This is also my bet. But theoretically everything you push or pull even if spastic should work without damaging anything. Maybe we have a bunch of myths that are not known to old engineers and tech nerds.

modern electronic handbrakes are proper E-brakes as in "Emergency" brakes. They use the abs system to perform an emergency stop. for cases like if the driver falls unconicous and a passenger could stop the car immediatly
@@ozan1234561if your brakes are leaking/malfunctioning you shouldn’t be driving the car at all. If they were leaking, you would have next to no stopping power, and once the fluid is gone, you would have zero stopping power.
I was teaching my daughter to drive last year in a 2023 Vauxhall Corsa with a button for a handbrake, i tried to pull it just the once and nothing happened, this experience defiantly shortened my life thinking i had zero control and now find out its pull and hold.
maybe when you momentarily pull just once, the car thinks you pulled it by mistake as oppose to pulling and holding it which it thinks you intentionally needed to stop
@@MrPaulNimeno I'm guessing this is what happened, i find out now she passed her test. If you look close enough you can probably still see imprints from my fingers in the Corsa :D
I used to drive buses and, all the models I drove included pneumatic actuated doors, which by their nature, are a tad laggy. When you push the button to open the door, it takes about 4 seconds before the doors actually open. Since we also stop as smooth as possible, we push the button before we've quite come to a standstill, that way, as soon as the bus stops, the doors open. This worked on all the buses I drove until our depot got some new buses. These new buses still had the lag between pushing the button and opening the doors but, would apply the emergency brake as soon as you touched that door open button. As a result, even though we're only moving at about 2 mph, when we push that button, if anyone is standing, they would get thrown off their feet. We all complained about this "feature" because we felt it was dangerous. Furthermore, if we waited for the bus to be at a complete standstill before pushing the button, our passengers would then experience the lag time. Causing them to glare at us for keeping them waiting. (believing we're doing this deliberately) Then on one occasion I decided to test what would happen if I pushed that button, while travelling at speed. While I had an empty bus, with no other traffic around, I braced myself by putting both feet against the dashboard. Then pushed the button at 20mph. Nothing happened. I then relaxed and put my feet back down, but then as i slowed to pull over, at about 8mph, the wheels locked up and I was thrown into the windscreen and then the doors opened. So it turns out that, although it wouldn't apply the brakes at speed, the bus would remember you've pushed that button and as soon as you've slowed down enough, it will then apply the emergency brakes. Hated those buses.
There is a major problem with electronic handbrakes... My friend has a new Ford Ranger 4x4 with electronic handbrake, he was on a trip recently and on an outback road which has river and creek crossings to contend with. His car was doing fine UNTIL... one of the river crossings flooded his alternator causing it to not charge the battery anymore. He found out whilst crossing another river when the battery completely died and the car automatically engaged the park brake, because the engine switched off. This left him stranded about two thirds the way across a flowing river with no way to move! Luckily, he was with other people in 4x4's and someone hooked up their winch and had to skull drag his car out of the river, which damaged the gearbox and transfer case.
@@Herc-h3d There likely a manual shiftlock release that I'd hope also disengages the brake. If a car dies with an automatic e-brake and needs to be towed there must be a way to disable it. I've seen a pull tab in the center console of some trucks but not sure if that was a Ford.
If transmission was damaged then it wasn't parking brake, he just towed his car with park lever engaged within gearbox or in drive. E-brake would actually saved his car because brakes would hold his wheels and not gearbox. And yeah, cars with automatic gearboxes go into park automatically when loosing power, some care have even hidden small battery just for this.
@@drayke8886 Nope. You're wrong! His car shifted to park when it lost power and because it's an electronic shift he couldn't get it out of park without power. The E-brake DID NOT save his car, it stranded the car in the middle of a flowing river!
@@Herc-h3d it's exactly what I said, e-brake wasn't engaged. Your friend was fighting with gearbox when towing, if the car would engage parking brake (as you said in 1st comment) he would fight brakes and nothing would be damaged. I'll say it more clearly for you, e-brake and "park" on transition are to separate systems. When parking on hill you should use e-brake to save transmission.
@PREDATEURLT it does. It check to see if it's able to build pressure and if not or it is not responding it will start applying park brake. How do you think all these ones work?
Fun fact... traditional hand brakes typically don't enable the rear lights which can be useful to briefly slow down while passing a certain something on the side of a highway. As for the hard braking... if I'm not mistaken manufacturers typically aim for about 1G of braking force which is about the limit the average driver can safely endure while minimizing the chance of losing control. BMW's stopping distance seems to closer to that while the chinese cars are like, "What's a G?".
@@LRK-GT I should add that if done repeatedly it can be rough on the rear brakes so be gentle. The stock assembly is typically not meant to be taking the full load of the vehicle and could end up warping the little rotors but it really depends on the model.
@@ouch1011 Chill brother, those days are behind me but for the record where I am they'll even try to pop you for going 75 with no traffic while the majority of drivers here have cruise control at 80 in the fast lane.
So, unlike a traditional handbrake with it's own mechanical setup, modern electronic handbrakes are just an input which the car can be programmed to react to in slightly different ways, but ultimately mostly just fully activates the regular service brake (which it can do otherwise already, since it's probably set up for auto emergency braking, braking during cruise control, etc)
Many of them I have seen electronically activate the caliper piston or shoes if they are drum brakes with a servo mounted to the rear of the respective mechanism. The point is to actually still have something to allow braking should the hydraulic / main portion of the braking system fails.
The electric parking brake is still done in a very similar fashion as a traditional parking brake, which is mechanical and completely separate from the hydraulic brakes, it’s just done electronically. Early systems literally just used a motor to pull a parking brake cable. However, when moving, using the parking brake to try and slow the car is 1) not very effective and 2) dangerous if the rear brakes lock up. This video showed that on the first car. So, modern systems use the ABS to stop that car using the hydraulic brakes. Much more effective and safe.
@@ouch1011 What are you basing this info on? ABS is integrated into the hydraulic portion of the braking system which the parking brake does not use on at least any model in the US I am aware of. They use a servo or motor that compresses the caliper piston or seperate shoes. All I have stop the car independantly of abs or hydraulic, and I have to drive several models of vehicles without using the service / hydraulic brakes as part of what I do for a living.
Front wheel drive cars used to have the handbrake on the front wheels in many cases because in snow or other difficult situations, you can apply the handbrake to even the torque between the driving wheels. Like old tractors that had a separate brake pedal for each rear wheel. It's a very crude form of diff-locking.
@@StephenButlerOne "safety" Honestly it's not a bad feature in the event you _need_ to use it, but it's still far safer to drive an older car with less nanny devices.
@@TheObsesedAnimeFreaks I'm not to sure about that. I've currently got an ioniq hybrid as a work car, and it may not be a sexy or sports car, it's a boring car, however it's probably the best car I've owned. Lots of emergency breaking functions, the best adaptive CC I've experienced, will take you to zero and then move off for you, it's lane keep, isn't the best I've used, but ok, Auto lights, and dippers, auto wipers, cooled and heated seats and wheel. I don't love the car, coming from a 19 Leon STFR 7DSG, before that a 16 GTC VXR, the ioniq is the better car. It just lack any type of character. But it's definitely the safest car I've owned in 30 years, and only going to get safer. I'm thinking of going Cupra Born next week, as I've never had an EV, and I have a feeling they aren't the future the industry like us to believe. So I want to try one before it's to late. Btw I love an ice car, hot hatches and warm estates (wagons), but I do like to swing wildly when picking cars. May go for a lexus OU 300e, that's looking decent too. I used to drive 100miles per week, I've just changed roles and I'll be working from home so I think an EV will fit in to the next couple of years into my life.the Cupra is winning ATM, as it has the hatchback vibe and is the only EV with positive handling ratings.
The point of the emergency brake is to allow you to bring the car to a stop in the event of brake failure. If all it does is use the brakes then its effectively useless in an emergency. The system on the BMW is completely seperate to the service brakes and while it might only apply to the rear wheels - and then only with limited force - it will still work if the main brakes can't for whatever reason. This is also mandatory in a lot of countries for road use. The rest look like they have one braking system and no redundancy with the e-brake simply being a way to engage brake assist without the pedal. If those brakes fail you've got no other options.
The e-brake on certain vehicles use the caliper to engage the brakes. If the brakes lose all fluid, the ebrake will still be functional. The caliper is mounted with a small motor to engage the pistons. Now if the caliper/s fail then there’s is no stopping it.
@@chasehilmy Thats how the BMW system works - the rear brakes are a disk over drum design so the disk is the service brake and the drum the handbrake or e-brake. Manual or electronic actuation doesn't make much difference but the Chinese cars shown here appear to use the same single system regardless of if its a pedal press or an e-brake pull. That leaves no redundancy which is the whole point of an e-brake in the first place. I suppose if the pedal itself snaps it might help but otherwise its fairly pointless.
"The point of the emergency brake is to allow you to bring the car to a stop in the event of brake failure. " This is a myth. It's not even an "emergency" brake, it's a parking brake. If it was meant to stop a moving car it wouldn't be on the rear axle, it'd be on the front. Locking your rear wheels is a bad fucking time.
The Chinese cars do utilise standard e-braking, but they also engage normal breaks. Don't like the stopping force though - can't help but think a child playing around will cause you to get a hard rear ending when you suddenly come to a perfect stop. I'll have to try it on my Civic and see what they chose for that
@@GF-mf7ml there is a way to remove the parking break, I don't know what that is exactly but I think it's a specialized too to reverse the parking mechanism out, like how semi's use cage bolts but different.
Well the question is, modern cars with emergency brake assist can also break by themself so i wonder if you pull the e handbrake they engage all 4 brakes the normal way or really only the handbrake. Because this looked like a strong brake engage, and not like you would expekt by only pulling the handbrake and only brake the rear wheels. The BMW braked like expected. So would be nice if you can disable the normal brake system on the other cars and test that again.
@@MelodicTurtleMetal yeah because i think its a way to get your car stoped in an emergency. So if your complete brake system fails what does the cars do? Nothing or really using hand brake to slow the car down
quora says: "You will crash if the entire system is empty . Parking brakes will not stop the vehicle in a reasonable time . They are not designed to stop the car in motion but to hold the car while it is parked. That is why they are no longer or seldom called “emergency” brakes but parking brakes"
With a mechanical hand brake, you wanna pull the leaver just enough to come into a controlled stop. You don’t wanna lock up the tires. If you pull too hard, the wheels lock up and you’ll slide. You apply the hand brake the same way you would with your regular brakes but keep in mind that the emergency brake does not feature ABS on older cars.
I have a 2019 Honda Insight.. I was teaching my daughter how to drive so I had to try this to see what would happen.. It happens exactly as it did in these newer cars.. AND I USED IT! TWO TIMES I had to pull that button up! The second time, the collision avoidance reacted faster than I did (thankfully) and kept her from rear ending the car in front of us. The first time, it was night time and she didn't see a car turning left in front of us.. I know people hate electronic e-brakes, but for me they saved my car..
The BMW is most likely programmed to safely stop if the passenger sees you having a stroke or something. It doesn't need to be a full emergency stop. You can do that with your foot as driver.
In my 2017 Chevy Impala, the E-brake button is on the driver's left side, over by the door. For a passenger to reach it, you would have to reach over the driver and around the steering wheel to get to it.
Waaaay back when I/we were very young, we often used the parking brake for assistance in cornering, especially on the gravel roads around the outskirts of town, was also great to perform a rapid U turn or "hand brakie" to quickly change to the opposite direction when PC Plod was after you...
Can you repeat the experiment without brake fluid or simulate a break in the hydraulic lines. Pretty sure the mechanical emergency brake reigns Superior.
@@otm646 For normal parking use yes. But I'm pretty sure that in the tested situation the hydraulic brakes were used too (at least in the Chinese cars). I think they even said, they heard the ABS engaging. And I don't think I't otherwise possible to stop that fast without completely locking any wheel. I would be interested too what happens if you remove all brake fluid. Simulating the unlikely event, that the hydraulic system has zero function and testing if the e-handbrake can be used as a fallback solution, like an old mechanical brake could be.
With the BMW, the rear parking brake will engage under 2 miles per hour and over 2 miles per hour, it uses the full braking system and the parking brake switch needs to be held for 2 seconds to activate.
The emergency brake has an ironic name. You use it every time you park in a manual, every time you park on a steep incline in an automatic and no one ever uses it during an actual emergency.
In a very old car I could lock the rear wheels with e-brake on snow. It was kind of fun. BTW, what's the advantage of using the electronic handbrake instead of traditional emergency braking using the foot brake? IMO the lever is there to use when parking. But well, when it's software-defined, it probably makes no sense to leave the parking function while still moving, so the first logical thing that comes to mind is just emergency braking (in chinese cars) or just smooth braking (in BMW). I think both options are fine. And even if it lock the rear wheels - it would be fine because it's a way to have fun in the snow ;) However, the lag is awful, I prefer mechanical handbrakes for that.
i think its nice that most of these electronic brakes need a bit of "convincing" before they engage...like the example mentioned in the video, i can see plenty of children curiously pressing buttons or flipping switches-- the car should give the driver those precious few split-seconds to get any hands away from risky inputs, but not take too long when theyre actually Needed...
I’ve owned 4 different vehicles with electric parking brake (2 GM, 1 Hyundai and 1 Kia). They all apply the service brakes when you pull the parking brake switch, then engage the parking brake when you are fully stopped. It’s basically the same as braking hard with the brake pedal, except it does it using the same system as the autonomous braking system (some use the ABS, others use an actuator to push the brake pedal).
I’m curious if it uses the hydraulic braking system fails what would happen? It seems like the electronic parking brake doesn’t use a separate emergency brake when it activates.
I'm not sure what the laws are in Russia, but in the US, they need to be two independent systems. So most likely, if the regular brakes failed, it will use the rear parking brake. This would be difficult to test, but I'd still love to see how it would perform.
Vlad, you and your lads do some amazing experiments with cars and engineering! Absolutely love the work you all put in! Great content! Many thanks for your very entertaining content. Much respect and admiration from Sth Australia ✌️☘️🙏
You forget that the computer is connected to all systems. Doesn't matter that the parking brake system only locks up one axle. Holding the switch back for an emergency brake causes the computer to actuate all brakes in the car, PLUS the emergency brake, for maximum stopping power. And who else knows what else it does. Lower the gear for engine braking or activate any other system. This is in case just a few wheel brakes fail, the computer will cause all brakes to actuate when the emergency brake is pulled. Whatever is left of the functioning brakes will contribute to stopping power. Absolutely *nothing* the driver does is directly connected to an engine system. Driving a modern car nowadays is like playing a video game. All the driver controls are just a big controller telling the computer what systems to engage. The driver will have zero control of the car is the computer malfunctions. Actually there are multiple computers in modern cars. Older cars had a steel cable connected to the emergency brake handle. Now it is just an electronic switch, which, when pulled, tells the computer to actuate the parking brake servo (or piston, not sure exactly how the parking brake is works in such a system) Pulling the switch up harder will NOT cause the brakes to squeeze more unlike in a manual cable system. The driver controls are NOT directly controlling anything. They just send signals to a computer which then sends signals to systems on the car to do the work with motors and pistons. Edit: Seems like you figured this out by the end of the video.
Meanwhile, Subaru Legacy and outback electronic handbrake (2017 at least) strait up LOCK all 4 wheel instantly, pure skid, 0 deceleration probably the most dangerous if your brake die
Years ago there was one Polish motoring paper that did this with 1st gen Peugeot 508 but they also tested brakes with empty systems, no fluid as if a brake line would be lost. Can't recall the exact detail, but it did function with at least any two brakes that have fluid in them. Possibly one caliper braking was also done, but I would have to check on that.
Interesting experiments with different cars, and bit of contrast among manual emergency brake to electronic brake version. 🎉🎉🎉 The bmw E brake seems the best of E-brake versions. However E brake and Manual brakes are principally intended for helping secure car when stopped and parked. So to bolster putting vehicle gearbox in lowest gear, or for automatic gearbox/transmission in Park. The increased inclusion of electronic, programmed, automatic feedback brake and other devices in cars is a double-edge-sword for leads car drives to become dependent on devices. Thus more oblivious to conditions present & dynamics along with Nature and its Laws.
On the next episode of Garage 54....Vlad limping around in a neck brace, arm in a cling & broken, and leg in a full leg brace. Why you ask, because someone screwed with his brakes in the last car....lol.
I like the bit at the end where the manual parking brake isn't even connected lol, kinda dangerous tho tbh if you have a brake master cylinder failure. The chinese cars are interesting, my hypothesis for the BMW is that the car does not actually want to wear down the parking brake shoes, BMW is pretty serious about protecting their hardware. it also might be to stop you from E-brake drifting.
BMW owner manual says that it's for if the driver goes unconscious or has a medical emergency anyone can stop the car with the electronic handbrake, it isn't meant to do the quickest stop...
Here in the States, we call it an emergency brake because all cars are required to have two seperate braking systems. The hydraulic brakes for normal use and the E-brakes in case the hydraulics fail. The E-brake is connected mechanically through cables like the brakes on a bicycle. The laws must be different in Russia because I'm pretty sure these electronic handbrakes wouldn't be usable in an emergency.
These are actually pretty common on new cars, i’m a mechanic in a southern state and they’re everywhere now. Absolutely despise them, they make my job harder and usually can’t be used when moving - they’re only for parking. I will never own a car with one for those reasons.
You call it an emergency brake because your standards of driver education are extremely poor. Locking the rear wheels up is a terrible thing to do in an emergency, it just makes the car unstable.
but what if the reason you are pulling the emergency brake is because your main brakes have actually failed in some way? how are these cars really going to stop if you have lost fluid.. this needs more testing
Depends on how the brakes have failed. If the rear brakes are completely shot, you have no chance of using the handbrake. Handbrake also bypasses the hydraulic system with a cable, so in a case of brake fluid loss, you can still apply the rear brakes.
It’s no longer an “emergency brake”. These electronic ones are called as “parking brake” now and the computer thinks it’s smarter than you and will let you put it as much as you want, but will never engage the brake. Because f**k you, that’s why. Cars past 2020 imo are bulls**t and tend towards consumerism than actual machines. Everything is made such that you cannot work on your own car and are shackled to the dealership and pay their insane premium on low quality oem parts.
Something is really off. Electronic handbrakes in most cars are just actuators which you press the brake pedal hard and just keep the rear calipers locked in position when you let off the pedal, they do not brake by their self, so if the hydraulic brake system fails you really don't have a handbrake. Something else must be going on with those cars, like sensing an emergency by pressing the handbrake button and do an emergency braking through the ABS unit which can be used to brake electronically without any pedal input. In which case if you really need a handbrake you're screwed cause you don't have any.
I had an old 2012 Toyota Avensis and the E-brake on that was a lot different... It would just completely lock up the rear wheels if i held the switch up whilst driving, so it definitely operated more traditionally on older Japanese cars!
ok, from what i can work out without googleing, long pull on E brake will apply the abs(chinese cars atleast) and when parking/using it normally it will apply with the servo motors on the calipers. in the event of hydrolic brake failure such as a hose bursting or seal blowing out, it will be exactly as useless as the brake pedal. but if it is a medical incident, then these are great. but emergency brakes should be an entirely seperate mechanical setup to cover both situations regardless. maybe even mechanical rear and hydrolic front to get the best of both worlds. 🤷
Thanks for this experiment. I've been too scared to try e-brake during driving tests in the past. My colleagues tell me you have to hold the e-brake but I just yell STOP STOP STOP when we're about to run a stop sign or red light.
Not entirely fair test for the mechanical lever e-brake ripping on it like that. I've used the mechanical lever e-brake in a car to slow down a car before. Mostly because i just wanted to know if it was possible. You can slowly pull it up and treat it as brakes that have no abs. It was interesting to see how the electronic handbrakes work though. I always assumed the e-brake button just wouldn't function while the car was moving. I feel like it should definitely be more common knowledge that the electronic e-brake button actually functions as an emergency button that stops the car safely.
In some cars there is a procedure you can do to disable the abs from working with the park brake so you get electronic park brake only. Each manufacturer is different.
I think it's got a lot to do with the anti skid setting why they are smooth at stopping. Will be interesting to see the button turned Off and try it👍💚💛❤️
being fair, using actual brakes for emergency is quite dumb usually you need that in case of service brake failure, no one's gonna use the e-brake if you can brake normally. also, it would be possible to stop earlier with an mechanical brake if you actually modulated it, and avoided to lock the tires up. same way you should never slam on the brakes in a car without abs (actually, in any car, abs is just a safety measure, not a replacement to human moduling)
also, a lot of older cars with disk brakes have the e-brake on the axle, wich is dumb, personally, i think the most elegant way i've seen that problem fixed is by using the rotor as a drum for a smaller drum brake for the e-brake
Ebrake purpose isn’t emergency braking, neither the handbrake was, e stands for electronic (although it seems American spies strongly believe in the emergency meaning). While it’s a good thing most modern cars manage it that way when pulled at speed, first gen ebrakes you don’t want to pull at speed because it will not behave like in the video! As for the 5 series weakness, it’s because bmw handbrakes uses a small drum on the inside of the rear discs instead of having a standard non-hydraulic activator on the rear callipers or a twin rear callipers setup
and I just assumed the electronic parking brakes were just that and did not have any sort of emergency function... good to know as both my daily drivers have that now!
My only concern is that e-brakes don’t seem to account for situations where the driver uses them due to normal brake failure, unless they are parking brakes equipped with an anti-lock mechanism for emergencies.
The chinese cars used the front brakes too. You can see the cars leaning forwards when braking that means the front axle is braking too. The BMW only used the rear brakes, that is why it took longer to stop. In Europe the parking brake is separate from the service brakes. I do not know if the chinese cars have 2 separate braking systems for all wheels, but the BMW does have one only for the rear brakes. When you pull the lever you activate that system I am not trying to defend BMW, I am just pointing out the differences
Modern auto boxes are electronic, so it won't shift until you come to a stop. Old "stupid" boxes will -when i was young and foolish, i tried to get a speeding ticket in reverse, because i figured that my car would do 80 kph in reverse. So i tried rehearsing a J-turn (because braking straight from 80 in reverse is extremely difficult), and i found that, on tarmac, in a RWD car with an auto it's much more difficult than in a FWD car with a manual, so i ditched the idea as too dangerous, even for my then-self. But it did shift from R to D, and from D to R on the move. Actually, the reverse speeding ticket stuff is redundant, because i did j-turns forward and in reverse plenty of times in the snow. So what happens is a bit of fun for a 21-year-old.
As the others said nothing happens in a modern car... In an older car with physical linkage it will go into reverse. If it's a powerful enough RWD car (like an SUV or a crown Vic) and you stab the throttle it'll spin the tires backwards. In a FWD car it has too much grip and just stalls the engine, but you can reverse real fast and slam it into drive and do a burnout. I've done all in a few old cars, never broke anything... I think the fastest I did it was about 50mph.
Great video guys. Here’s a suggestion for one. What happens when you run an engine with diesel fuel in place of engine oil? I know some people will flush engines with it, but will it cause damage to the engine (or clean it out) if you use it as the engines lubricant.
Those first 2 Chinese vehicles were rather attractive looking, especially the Arrizo. I guess Chinese cars aren't ugly misproportioned boxes anymore.. But that Lada...if there were a Miss Universe contest for cars there's your winner!
China are making some of the nicest looking cars around - also some of the best built right now. Heavy government initiatives and rebates designed to be the world leaders in modern cars, especially EVs. They are so good, and so heavily government subsidized, that literally no country can compete and have had to heavily tax Chinese imports to protect their own car industry. Only good thing about Australia right now - we have no car industry, so we get greedy cars in the cheap that the government won't tax (can't legally justify it either, so hopefully it'll stay that way).
Vaxhuall insignia mk1 before they did the recall you could pull it at any speed as me and my dad found out. He said no it won't work look, next thing you know we came too a stop on the motorway with 4 burnt out tyres. Like driving with cubes on, only a few months later they recalled them to correct the software due to an accident.
In my opinion BMW did it the best. If your passenger is fooling around and "pulls the trigger" just for fun you don't want the car to do an emergency stop with full braking force. Think about what would happen at much higher speed - maybe on a wet or snowy road - when someone activates the E-brake and you, as the driver, don't expect the car to behave like the chinese did. You would probably loose control and crash.
After seeing a clip on FunkFPV's channel of a *_brand new,_* fresh off the trailer, Chinese vehicle whose rear trailing arm's weld broke at the bushing mount (the circular part the bushing and bolt gooles through)... I was worried these shenanigans would result in similar! 😒 That other one was sad, too. You could see ask the Inspection Markings where someone used their green marker to indicate all is good... Whereas the welds didn't even look good on the outside! 😞
"Only do this with cars you rent" LMAO🤣😂
den whats wrong??
This is the intended use case of the e-brake. It's described in the manual of the car.

I used to drive buses and, all the models I drove included pneumatic actuated doors, which by their nature, are a tad laggy. When you push the button to open the door, it takes about 4 seconds before the doors actually open. Since we also stop as smooth as possible, we push the button before we've quite come to a standstill, that way, as soon as the bus stops, the doors open. This worked on all the buses I drove until our depot got some new buses.
These new buses still had the lag between pushing the button and opening the doors but, would apply the emergency brake as soon as you touched that door open button. As a result, even though we're only moving at about 2 mph, when we push that button, if anyone is standing, they would get thrown off their feet. We all complained about this "feature" because we felt it was dangerous. Furthermore, if we waited for the bus to be at a complete standstill before pushing the button, our passengers would then experience the lag time. Causing them to glare at us for keeping them waiting. (believing we're doing this deliberately)
Then on one occasion I decided to test what would happen if I pushed that button, while travelling at speed. While I had an empty bus, with no other traffic around, I braced myself by putting both feet against the dashboard. Then pushed the button at 20mph. Nothing happened. I then relaxed and put my feet back down, but then as i slowed to pull over, at about 8mph, the wheels locked up and I was thrown into the windscreen and then the doors opened.
So it turns out that, although it wouldn't apply the brakes at speed, the bus would remember you've pushed that button and as soon as you've slowed down enough, it will then apply the emergency brakes. Hated those buses.
@@KenFullman thats a terrible feature on those busses, and probably also a safety hazard 😂
omg the ending , rip in the forest
Fortunately, with manual transmissions, you can slow down a lot without using your brakes.

There is a major problem with electronic handbrakes...
My friend has a new Ford Ranger 4x4 with electronic handbrake, he was on a trip recently and on an outback road which has river and creek crossings to contend with. His car was doing fine UNTIL... one of the river crossings flooded his alternator causing it to not charge the battery anymore. He found out whilst crossing another river when the battery completely died and the car automatically engaged the park brake, because the engine switched off. This left him stranded about two thirds the way across a flowing river with no way to move! Luckily, he was with other people in 4x4's and someone hooked up their winch and had to skull drag his car out of the river, which damaged the gearbox and transfer case.
@@Herc-h3d There likely a manual shiftlock release that I'd hope also disengages the brake. If a car dies with an automatic e-brake and needs to be towed there must be a way to disable it. I've seen a pull tab in the center console of some trucks but not sure if that was a Ford.
If transmission was damaged then it wasn't parking brake, he just towed his car with park lever engaged within gearbox or in drive.
E-brake would actually saved his car because brakes would hold his wheels and not gearbox.
And yeah, cars with automatic gearboxes go into park automatically when loosing power, some care have even hidden small battery just for this.
@@drayke8886 Nope. You're wrong! His car shifted to park when it lost power and because it's an electronic shift he couldn't get it out of park without power. The E-brake DID NOT save his car, it stranded the car in the middle of a flowing river!
@@Herc-h3d it's exactly what I said, e-brake wasn't engaged.
Your friend was fighting with gearbox when towing, if the car would engage parking brake (as you said in 1st comment) he would fight brakes and nothing would be damaged.
I'll say it more clearly for you, e-brake and "park" on transition are to separate systems. When parking on hill you should use e-brake to save transmission.
@@drayke8886 BOTH engage when the engine switches off or loses power. He was fighting BOTH gearbox and brakes.
New cars on this channel, what a treat!!
Indeed 😂 Also what happened at the end is shocking and funny
But only Chinese ones. But no wonder after that friendship between Putin and ping.
Probably paid promo experiment
In VW it will apply abs at max and then apply park once it is at lower speed
So it wont work if lets say main brake would fail?
@PREDATEURLT it does. It check to see if it's able to build pressure and if not or it is not responding it will start applying park brake. How do you think all these ones work?
Does it also downshift to low gears to make maximum use of engine breaking? In case of DSG of course
@5Dale65 it does automatically. When dsg senses hard braking it will down shift. In sport this is more noticeable. But it does not down shift harsh.
I tried this in my 2019 Leon ST FR dsg and it felt like all four calipers engaged. It felt violent.
It is mind boggling reading the comments and seeing how many people are clueless as to how electric e-brakes work. 😂
Pls enlighten us
I don’t know, that’s why I’m watching these videos, to educate myself.
Fun fact... traditional hand brakes typically don't enable the rear lights which can be useful to briefly slow down while passing a certain something on the side of a highway.
As for the hard braking... if I'm not mistaken manufacturers typically aim for about 1G of braking force which is about the limit the average driver can safely endure while minimizing the chance of losing control. BMW's stopping distance seems to closer to that while the chinese cars are like, "What's a G?".
Also doesn't dip the nose. Totally haven't used the E-Brake for that...
@@LRK-GT I should add that if done repeatedly it can be rough on the rear brakes so be gentle. The stock assembly is typically not meant to be taking the full load of the vehicle and could end up warping the little rotors but it really depends on the model.
Or you could just not drive like a piece of shit. Cops don’t pull you over unless you’re speeding a LOT.
@@ouch1011 Chill brother, those days are behind me but for the record where I am they'll even try to pop you for going 75 with no traffic while the majority of drivers here have cruise control at 80 in the fast lane.
Do cops in USA really pull over for braking?
In Europe they have to have a proof: number on speed radar.
So, unlike a traditional handbrake with it's own mechanical setup, modern electronic handbrakes are just an input which the car can be programmed to react to in slightly different ways, but ultimately mostly just fully activates the regular service brake (which it can do otherwise already, since it's probably set up for auto emergency braking, braking during cruise control, etc)
Many of them I have seen electronically activate the caliper piston or shoes if they are drum brakes with a servo mounted to the rear of the respective mechanism. The point is to actually still have something to allow braking should the hydraulic / main portion of the braking system fails.
@@D3M3NT3Dstrang3rThis is what I'd really like to see tested. Some way to temporarily disengage the main lines and then test various cars.
The electric parking brake is still done in a very similar fashion as a traditional parking brake, which is mechanical and completely separate from the hydraulic brakes, it’s just done electronically. Early systems literally just used a motor to pull a parking brake cable. However, when moving, using the parking brake to try and slow the car is 1) not very effective and 2) dangerous if the rear brakes lock up. This video showed that on the first car. So, modern systems use the ABS to stop that car using the hydraulic brakes. Much more effective and safe.
@@ouch1011 What are you basing this info on? ABS is integrated into the hydraulic portion of the braking system which the parking brake does not use on at least any model in the US I am aware of. They use a servo or motor that compresses the caliper piston or seperate shoes. All I have stop the car independantly of abs or hydraulic, and I have to drive several models of vehicles without using the service / hydraulic brakes as part of what I do for a living.
Meanwhile, older Citroens applied the handbrake on the front axles, just to make sure you don't do anything silly... :P
Old SAAB's as well
Some audis as well actually
Front wheel drive cars used to have the handbrake on the front wheels in many cases because in snow or other difficult situations, you can apply the handbrake to even the torque between the driving wheels. Like old tractors that had a separate brake pedal for each rear wheel. It's a very crude form of diff-locking.
So basically there programing the fun out of cars 😂😂🤦♂️ great video as usual guys 👌
Or programming safety into cars.
@@StephenButlerOne "safety"
Honestly it's not a bad feature in the event you _need_ to use it, but it's still far safer to drive an older car with less nanny devices.
@@TheObsesedAnimeFreaks I'm not to sure about that. I've currently got an ioniq hybrid as a work car, and it may not be a sexy or sports car, it's a boring car, however it's probably the best car I've owned. Lots of emergency breaking functions, the best adaptive CC I've experienced, will take you to zero and then move off for you, it's lane keep, isn't the best I've used, but ok,
Auto lights, and dippers, auto wipers, cooled and heated seats and wheel.
I don't love the car, coming from a 19 Leon STFR 7DSG, before that a 16 GTC VXR, the ioniq is the better car. It just lack any type of character.
But it's definitely the safest car I've owned in 30 years, and only going to get safer. I'm thinking of going Cupra Born next week, as I've never had an EV, and I have a feeling they aren't the future the industry like us to believe. So I want to try one before it's to late.
Btw I love an ice car, hot hatches and warm estates (wagons), but I do like to swing wildly when picking cars. May go for a lexus OU 300e, that's looking decent too.
I used to drive 100miles per week, I've just changed roles and I'll be working from home so I think an EV will fit in to the next couple of years into my life.the Cupra is winning ATM, as it has the hatchback vibe and is the only EV with positive handling ratings.

The point of the emergency brake is to allow you to bring the car to a stop in the event of brake failure. If all it does is use the brakes then its effectively useless in an emergency.
The system on the BMW is completely seperate to the service brakes and while it might only apply to the rear wheels - and then only with limited force - it will still work if the main brakes can't for whatever reason. This is also mandatory in a lot of countries for road use.
The rest look like they have one braking system and no redundancy with the e-brake simply being a way to engage brake assist without the pedal.
If those brakes fail you've got no other options.
yup ... I'd rather have a completely seperate and mechanical system for emergency brake.
The e-brake on certain vehicles use the caliper to engage the brakes. If the brakes lose all fluid, the ebrake will still be functional. The caliper is mounted with a small motor to engage the pistons. Now if the caliper/s fail then there’s is no stopping it.
@@chasehilmy Thats how the BMW system works - the rear brakes are a disk over drum design so the disk is the service brake and the drum the handbrake or e-brake.
Manual or electronic actuation doesn't make much difference but the Chinese cars shown here appear to use the same single system regardless of if its a pedal press or an e-brake pull. That leaves no redundancy which is the whole point of an e-brake in the first place.
I suppose if the pedal itself snaps it might help but otherwise its fairly pointless.
"The point of the emergency brake is to allow you to bring the car to a stop in the event of brake failure. "
This is a myth. It's not even an "emergency" brake, it's a parking brake. If it was meant to stop a moving car it wouldn't be on the rear axle, it'd be on the front. Locking your rear wheels is a bad fucking time.
The Chinese cars do utilise standard e-braking, but they also engage normal breaks.
Don't like the stopping force though - can't help but think a child playing around will cause you to get a hard rear ending when you suddenly come to a perfect stop.
I'll have to try it on my Civic and see what they chose for that
My intrusive thoughts every time I get on the highway
The best intrusive though in cars still using a mechanical key: will removing the key at 130 km/h activate the neman?
that's one feature of modern cars i like lol. they just are alleged to be a pain if you end up with a dead battery or need a tow.
I have more than 3 cars dead battery or battery disconnected are common. I don't want to deal with these problems.
@@GF-mf7ml there is a way to remove the parking break, I don't know what that is exactly but I think it's a specialized too to reverse the parking mechanism out, like how semi's use cage bolts but different.
the last one at the end was hilarious got to love it you guys rock, kudos.
Well the question is, modern cars with emergency brake assist can also break by themself so i wonder if you pull the e handbrake they engage all 4 brakes the normal way or really only the handbrake. Because this looked like a strong brake engage, and not like you would expekt by only pulling the handbrake and only brake the rear wheels. The BMW braked like expected. So would be nice if you can disable the normal brake system on the other cars and test that again.
They're definitely using the entire brake system. The BMW is as well, but under two miles per hour the BMW will only use the rear parking brake.
On my Mazda6, when I pulled the ebrake during snow it locks up all 4 tires
It uses both, which is sad - I'd prefer it just lock up the rear wheels.
@@MelodicTurtleMetal yeah because i think its a way to get your car stoped in an emergency. So if your complete brake system fails what does the cars do? Nothing or really using hand brake to slow the car down

@@Phantom-rb8yv he's a whack. not funny
quora says: "You will crash if the entire system is empty . Parking brakes will not stop the vehicle in a reasonable time . They are not designed to stop the car in motion but to hold the car while it is parked. That is why they are no longer or seldom called “emergency” brakes but parking brakes"
My VW Passat apply full ABS braking. feels like an anchor dropping from the tailgate ⚓️
The end… I’m crying 😂😂
With a mechanical hand brake, you wanna pull the leaver just enough to come into a controlled stop. You don’t wanna lock up the tires. If you pull too hard, the wheels lock up and you’ll slide. You apply the hand brake the same way you would with your regular brakes but keep in mind that the emergency brake does not feature ABS on older cars.
I love how they are actually using the seat belt and shoulder restraint. That's unusual for them.
I have a 2019 Honda Insight.. I was teaching my daughter how to drive so I had to try this to see what would happen.. It happens exactly as it did in these newer cars.. AND I USED IT! TWO TIMES I had to pull that button up! The second time, the collision avoidance reacted faster than I did (thankfully) and kept her from rear ending the car in front of us. The first time, it was night time and she didn't see a car turning left in front of us.. I know people hate electronic e-brakes, but for me they saved my car..
The BMW is most likely programmed to safely stop if the passenger sees you having a stroke or something. It doesn't need to be a full emergency stop. You can do that with your foot as driver.
This channel is awesome. The video quality is perfect
😂the ending
LOL!
If you are in a car equipped with an electric handbrake and the driver has a medical episode, You can pull the electric handbrake to stop the car.
Yes, that seems to be the best explanation for this sort of functionality - in case of driver incapacitation.
In my 2017 Chevy Impala, the E-brake button is on the driver's left side, over by the door. For a passenger to reach it, you would have to reach over the driver and around the steering wheel to get to it.
Why is this a comment? E is short for Emergency brake e.g. "a medical episode"
It's also intended to be used if your main brakes fail, which is why it uses a secondary braking system.
@@matthopper1925 what if the secondary uses the main system
Waaaay back when I/we were very young, we often used the parking brake for assistance in cornering, especially on the gravel roads around the outskirts of town, was also great to perform a rapid U turn or "hand brakie" to quickly change to the opposite direction when PC Plod was after you...
Can you repeat the experiment without brake fluid or simulate a break in the hydraulic lines. Pretty sure the mechanical emergency brake reigns Superior.
In no instance does the parking brake use the hydraulic system. It's an electronic parking brake, the EPB is controlled by the ABS unit and ECU
@@otm646 u sure about those Ch1nese cars
'Modern' (been the case for decades) braking systems consist of multiple independent hydraulic circuits. It would be improbable to lose all at once.
The e-brake system uses a motor on each of the rear calipers, brake fluid is not an issue.
@@otm646 For normal parking use yes.
But I'm pretty sure that in the tested situation the hydraulic brakes were used too (at least in the Chinese cars).
I think they even said, they heard the ABS engaging. And I don't think I't otherwise possible to stop that fast without completely locking any wheel.
I would be interested too what happens if you remove all brake fluid.
Simulating the unlikely event, that the hydraulic system has zero function and testing if the e-handbrake can be used as a fallback solution, like an old mechanical brake could be.
This was a great video - keep it up Garage 54- testing extreme motor car stuff we are afraid to do ourselves.
With the BMW, the rear parking brake will engage under 2 miles per hour and over 2 miles per hour, it uses the full braking system and the parking brake switch needs to be held for 2 seconds to activate.
That ending. LOL 😂
The emergency brake has an ironic name.
You use it every time you park in a manual, every time you park on a steep incline in an automatic and no one ever uses it during an actual emergency.
In a very old car I could lock the rear wheels with e-brake on snow. It was kind of fun. BTW, what's the advantage of using the electronic handbrake instead of traditional emergency braking using the foot brake? IMO the lever is there to use when parking. But well, when it's software-defined, it probably makes no sense to leave the parking function while still moving, so the first logical thing that comes to mind is just emergency braking (in chinese cars) or just smooth braking (in BMW). I think both options are fine. And even if it lock the rear wheels - it would be fine because it's a way to have fun in the snow ;) However, the lag is awful, I prefer mechanical handbrakes for that.
i think its nice that most of these electronic brakes need a bit of "convincing" before they engage...like the example mentioned in the video, i can see plenty of children curiously pressing buttons or flipping switches-- the car should give the driver those precious few split-seconds to get any hands away from risky inputs, but not take too long when theyre actually Needed...
Another great video, yall have done everything from a to backwards r at this point.. great work
I’ve owned 4 different vehicles with electric parking brake (2 GM, 1 Hyundai and 1 Kia). They all apply the service brakes when you pull the parking brake switch, then engage the parking brake when you are fully stopped. It’s basically the same as braking hard with the brake pedal, except it does it using the same system as the autonomous braking system (some use the ABS, others use an actuator to push the brake pedal).
Garage 54 for American president
You started a video without saying "Hey, there fellas"? That is a first!
My Dark Horse has an electronic hand break that can legit be used to drift with.
Sounds like something Ford would do)
I’m curious if it uses the hydraulic braking system fails what would happen? It seems like the electronic parking brake doesn’t use a separate emergency brake when it activates.
They typically use an electric motor.
Yea seems like it uses front wheels and abs very well and emergency aka handbrake is meant to be when normal brakes failure?
I'm not sure what the laws are in Russia, but in the US, they need to be two independent systems. So most likely, if the regular brakes failed, it will use the rear parking brake. This would be difficult to test, but I'd still love to see how it would perform.
Vlad, you and your lads do some amazing experiments with cars and engineering! Absolutely love the work you all put in! Great content! Many thanks for your very entertaining content. Much respect and admiration from Sth Australia ✌️☘️🙏
You forget that the computer is connected to all systems. Doesn't matter that the parking brake system only locks up one axle. Holding the switch back for an emergency brake causes the computer to actuate all brakes in the car, PLUS the emergency brake, for maximum stopping power. And who else knows what else it does. Lower the gear for engine braking or activate any other system. This is in case just a few wheel brakes fail, the computer will cause all brakes to actuate when the emergency brake is pulled. Whatever is left of the functioning brakes will contribute to stopping power. Absolutely *nothing* the driver does is directly connected to an engine system. Driving a modern car nowadays is like playing a video game. All the driver controls are just a big controller telling the computer what systems to engage. The driver will have zero control of the car is the computer malfunctions. Actually there are multiple computers in modern cars. Older cars had a steel cable connected to the emergency brake handle. Now it is just an electronic switch, which, when pulled, tells the computer to actuate the parking brake servo (or piston, not sure exactly how the parking brake is works in such a system) Pulling the switch up harder will NOT cause the brakes to squeeze more unlike in a manual cable system. The driver controls are NOT directly controlling anything. They just send signals to a computer which then sends signals to systems on the car to do the work with motors and pistons.
Edit: Seems like you figured this out by the end of the video.
The last car lmao
Hahahahaha.. the end was seriously faaarny. Interesting vid. But the humour made it worthwhile.
Those are pretty strong breaks, honestly impressed.
We got dubbed car videos before GTA 6
Meanwhile, Subaru Legacy and outback electronic handbrake (2017 at least) strait up LOCK all 4 wheel instantly, pure skid, 0 deceleration probably the most dangerous if your brake die
The Lada though LOL 🛼
Years ago there was one Polish motoring paper that did this with 1st gen Peugeot 508 but they also tested brakes with empty systems, no fluid as if a brake line would be lost. Can't recall the exact detail, but it did function with at least any two brakes that have fluid in them. Possibly one caliper braking was also done, but I would have to check on that.
Interesting experiments with different cars, and bit of contrast among manual emergency brake to electronic brake version. 🎉🎉🎉
The bmw E brake seems the best of E-brake versions.
However E brake and Manual brakes are principally intended for helping secure car when stopped and parked. So to bolster putting vehicle gearbox in lowest gear, or for automatic gearbox/transmission in Park.
The increased inclusion of electronic, programmed, automatic feedback brake and other devices in cars is a double-edge-sword for leads car drives to become dependent on devices. Thus more oblivious to conditions present & dynamics along with Nature and its Laws.
Very interesting indeed. Thanks for testing and sharing!!
On the next episode of Garage 54....Vlad limping around in a neck brace, arm in a cling & broken, and leg in a full leg brace. Why you ask, because someone screwed with his brakes in the last car....lol.
I like the bit at the end where the manual parking brake isn't even connected lol, kinda dangerous tho tbh if you have a brake master cylinder failure. The chinese cars are interesting, my hypothesis for the BMW is that the car does not actually want to wear down the parking brake shoes, BMW is pretty serious about protecting their hardware. it also might be to stop you from E-brake drifting.
emergency brakes are not meant to lock up that defeats their purpose. they are to take you to a safe stop.
BMW owner manual says that it's for if the driver goes unconscious or has a medical emergency anyone can stop the car with the electronic handbrake, it isn't meant to do the quickest stop...
Here in the States, we call it an emergency brake because all cars are required to have two seperate braking systems. The hydraulic brakes for normal use and the E-brakes in case the hydraulics fail. The E-brake is connected mechanically through cables like the brakes on a bicycle. The laws must be different in Russia because I'm pretty sure these electronic handbrakes wouldn't be usable in an emergency.
These are actually pretty common on new cars, i’m a mechanic in a southern state and they’re everywhere now. Absolutely despise them, they make my job harder and usually can’t be used when moving - they’re only for parking. I will never own a car with one for those reasons.
The e-brake on my car engages electronically. You can hear the motor running when it engages or disengages.
Newer cars do not use a mechanical cable to actuate the e-brake. It's electronic, there is a motor on each of the rear calipers.
they are plain unsafe , all new cars are like that, but that is no way an emergency brake, if you car electronics is dead/faulty, good luck braking
You call it an emergency brake because your standards of driver education are extremely poor. Locking the rear wheels up is a terrible thing to do in an emergency, it just makes the car unstable.
but what if the reason you are pulling the emergency brake is because your main brakes have actually failed in some way? how are these cars really going to stop if you have lost fluid.. this needs more testing
The electric hand brake uses an electric motor.
Depends on how the brakes have failed. If the rear brakes are completely shot, you have no chance of using the handbrake.
Handbrake also bypasses the hydraulic system with a cable, so in a case of brake fluid loss, you can still apply the rear brakes.
It's not an EMERGENCY brake ffs. It's a PARKING brake. There's a reason there's a letter 'P' on it, and it doesn't stand for emergency.
In a hybrid the motors run backwards in an emergency.
It’s no longer an “emergency brake”. These electronic ones are called as “parking brake” now and the computer thinks it’s smarter than you and will let you put it as much as you want, but will never engage the brake. Because f**k you, that’s why.
Cars past 2020 imo are bulls**t and tend towards consumerism than actual machines. Everything is made such that you cannot work on your own car and are shackled to the dealership and pay their insane premium on low quality oem parts.
Something is really off. Electronic handbrakes in most cars are just actuators which you press the brake pedal hard and just keep the rear calipers locked in position when you let off the pedal, they do not brake by their self, so if the hydraulic brake system fails you really don't have a handbrake.
Something else must be going on with those cars, like sensing an emergency by pressing the handbrake button and do an emergency braking through the ABS unit which can be used to brake electronically without any pedal input.
In which case if you really need a handbrake you're screwed cause you don't have any.
i love the (in some cars you never heard of) in the tittle XD and i know all of them
Growing up, this was called a "Starsky and Hutch".
Try going 60mph and then shifting to Reverse. lol
LADA (or whatever car in white was). it should NOT suppose to break when pulled level you MUST hold it to engage. LADA works INCORRECTLY
I had an old 2012 Toyota Avensis and the E-brake on that was a lot different... It would just completely lock up the rear wheels if i held the switch up whilst driving, so it definitely operated more traditionally on older Japanese cars!
They are called “Parking” brakes in the US and not “Emergency” brakes for a reason. They don’t work like old time brakes.
ok, from what i can work out without googleing, long pull on E brake will apply the abs(chinese cars atleast) and when parking/using it normally it will apply with the servo motors on the calipers. in the event of hydrolic brake failure such as a hose bursting or seal blowing out, it will be exactly as useless as the brake pedal. but if it is a medical incident, then these are great. but emergency brakes should be an entirely seperate mechanical setup to cover both situations regardless. maybe even mechanical rear and hydrolic front to get the best of both worlds. 🤷
It's funny that the BMW didn't turn the hazard lights on during the emergency stop
Thanks for this experiment. I've been too scared to try e-brake during driving tests in the past. My colleagues tell me you have to hold the e-brake but I just yell STOP STOP STOP when we're about to run a stop sign or red light.
Not entirely fair test for the mechanical lever e-brake ripping on it like that. I've used the mechanical lever e-brake in a car to slow down a car before. Mostly because i just wanted to know if it was possible. You can slowly pull it up and treat it as brakes that have no abs.
It was interesting to see how the electronic handbrakes work though. I always assumed the e-brake button just wouldn't function while the car was moving. I feel like it should definitely be more common knowledge that the electronic e-brake button actually functions as an emergency button that stops the car safely.
In some cars there is a procedure you can do to disable the abs from working with the park brake so you get electronic park brake only. Each manufacturer is different.
I think it's got a lot to do with the anti skid setting why they are smooth at stopping. Will be interesting to see the button turned Off and try it👍💚💛❤️
Electric park brake works very well as an emergency brake
Guess what! The Lada at the end is absolutely not road legal 😂
That BMw has painted door, the ending was funny poor vlad must be in the trees now
Lights actually come on too!!with lever hand brakes they dont come on!!😂😂😂
Hand Brakes are great for Bootlegger U-turns.
being fair, using actual brakes for emergency is quite dumb
usually you need that in case of service brake failure, no one's gonna use the e-brake if you can brake normally.
also, it would be possible to stop earlier with an mechanical brake if you actually modulated it, and avoided to lock the tires up. same way you should never slam on the brakes in a car without abs (actually, in any car, abs is just a safety measure, not a replacement to human moduling)
also, a lot of older cars with disk brakes have the e-brake on the axle, wich is dumb, personally, i think the most elegant way i've seen that problem fixed is by using the rotor as a drum for a smaller drum brake for the e-brake
Ebrake purpose isn’t emergency braking, neither the handbrake was, e stands for electronic (although it seems American spies strongly believe in the emergency meaning). While it’s a good thing most modern cars manage it that way when pulled at speed, first gen ebrakes you don’t want to pull at speed because it will not behave like in the video!
As for the 5 series weakness, it’s because bmw handbrakes uses a small drum on the inside of the rear discs instead of having a standard non-hydraulic activator on the rear callipers or a twin rear callipers setup
@Garage 54 now try shift gearbox in "P" while driving
and I just assumed the electronic parking brakes were just that and did not have any sort of emergency function... good to know as both my daily drivers have that now!
My only concern is that e-brakes don’t seem to account for situations where the driver uses them due to normal brake failure, unless they are parking brakes equipped with an anti-lock mechanism for emergencies.
Only do this with cars you rent 💀💀
I had a Getz. It was pretty damn reliable. Good economy, never let me stranded. Sold it cuz it didnt had AC 🥵
WOW you got a car from the last 100 yearas for a change!!
It's good to know this.
Of course, the owner's manual tells about this.
Problem is, nobody reads them... LOL!
This is what youtube needs
This is why there actually called a parking brake NOT an emergency brake! This is not something you should be using in an emergency situation!
The chinese cars used the front brakes too. You can see the cars leaning forwards when braking that means the front axle is braking too. The BMW only used the rear brakes, that is why it took longer to stop. In Europe the parking brake is separate from the service brakes. I do not know if the chinese cars have 2 separate braking systems for all wheels, but the BMW does have one only for the rear brakes. When you pull the lever you activate that system
I am not trying to defend BMW, I am just pointing out the differences
I don't care about braking distance, the real question is, can you do handbrake turns with an e-brake.(when you disable esp)
thanks, good to know i always feared to try it
what happens if you shift the gear to R or P while driving? applying light break if needed while driving fast
On mine nothing until you hit zero speed and touch the brake,
Modern auto boxes are electronic, so it won't shift until you come to a stop. Old "stupid" boxes will -when i was young and foolish, i tried to get a speeding ticket in reverse, because i figured that my car would do 80 kph in reverse. So i tried rehearsing a J-turn (because braking straight from 80 in reverse is extremely difficult), and i found that, on tarmac, in a RWD car with an auto it's much more difficult than in a FWD car with a manual, so i ditched the idea as too dangerous, even for my then-self. But it did shift from R to D, and from D to R on the move.
Actually, the reverse speeding ticket stuff is redundant, because i did j-turns forward and in reverse plenty of times in the snow. So what happens is a bit of fun for a 21-year-old.
As the others said nothing happens in a modern car...
In an older car with physical linkage it will go into reverse. If it's a powerful enough RWD car (like an SUV or a crown Vic) and you stab the throttle it'll spin the tires backwards.
In a FWD car it has too much grip and just stalls the engine, but you can reverse real fast and slam it into drive and do a burnout.
I've done all in a few old cars, never broke anything... I think the fastest I did it was about 50mph.
Great video guys. Here’s a suggestion for one.
What happens when you run an engine with diesel fuel in place of engine oil? I know some people will flush engines with it, but will it cause damage to the engine (or clean it out) if you use it as the engines lubricant.
Those first 2 Chinese vehicles were rather attractive looking, especially the Arrizo. I guess Chinese cars aren't ugly misproportioned boxes anymore..
But that Lada...if there were a Miss Universe contest for cars there's your winner!
China are making some of the nicest looking cars around - also some of the best built right now. Heavy government initiatives and rebates designed to be the world leaders in modern cars, especially EVs. They are so good, and so heavily government subsidized, that literally no country can compete and have had to heavily tax Chinese imports to protect their own car industry.
Only good thing about Australia right now - we have no car industry, so we get greedy cars in the cheap that the government won't tax (can't legally justify it either, so hopefully it'll stay that way).
In the 1970's Saab used a cable as a back up on the front disk brakes
Vaxhuall insignia mk1 before they did the recall you could pull it at any speed as me and my dad found out. He said no it won't work look, next thing you know we came too a stop on the motorway with 4 burnt out tyres. Like driving with cubes on, only a few months later they recalled them to correct the software due to an accident.
In my opinion BMW did it the best. If your passenger is fooling around and "pulls the trigger" just for fun you don't want the car to do an emergency stop with full braking force. Think about what would happen at much higher speed - maybe on a wet or snowy road - when someone activates the E-brake and you, as the driver, don't expect the car to behave like the chinese did. You would probably loose control and crash.
After seeing a clip on FunkFPV's channel of a *_brand new,_* fresh off the trailer, Chinese vehicle whose rear trailing arm's weld broke at the bushing mount (the circular part the bushing and bolt gooles through)... I was worried these shenanigans would result in similar! 😒
That other one was sad, too. You could see ask the Inspection Markings where someone used their green marker to indicate all is good... Whereas the welds didn't even look good on the outside! 😞
