Awesome explanation and video! I learned in Physics before ABS became a standard item in most vehicles that rolling to a stop is better than locking your brakes to avoid skidding. That meant pumping your brakes about 60 times per second. Lucky there's ABS! Thank you very much Dr. Kyle and Sabine.
Sorry for highjacking your comment. But why the fuck would i know what a "slip ratio" is or a "coeffecient of friction" is if i dont even know how ABS works? What university professor is this guy teaching? And what university professor doesn't know what ABS is? How can people be so "unaware" of what they're doing? I just want to know what ABS is, such a simple system yet such complex physics concepts are applied to explain it? Videos like this are exactly why bourbaki exists and ends up having to write mathematics textbooks themsellves
@@MU5T1 not really sure how to respond to this. introducing abs is exactly what this video did, lol. if any physics student watched this video alone and managed to build a custom abs system, his brain would probably be preserved for research, since it could performs miracles. just my opinion: if a physics student gets to the point of needing to develop an abs system, he would probably have completed highschool physics and a few years of college, and would not benefit from the explanation in this video.
You can test this system really easy in winter with the shiny slick snow ice surface. Hit the brakes hard and you’ll hear the ABS pump go to work and the brake pedal will pulsate. It’s kinda fun to do in a safe area and this system really works I can’t believe cars were made without this system
I kept on asking if the Friction is more in sliding why car would stop In less distance with ABS . Really thanks for providing the answer . Really appreciate your good work
This is just an old advice which can be detrimental in any modern car or bike with or without ABS. ABS system will be turned off if brakes are pumped and in a non ABS car which uses hydraulic braking system or power brakes will lose any kind of braking ability. Because of the vacuum pressure inside the valves, both ABS and non ABS cars use hydraulic system while ABS just prevents wheels from locking up and give steering ability in an emergency situation. It's written in a car manual. This advice is still rolling around because people just don't understand how a modern Braking system works. And yes, ABS works in milliseconds which no human can match.
An old racing trick. Since roads are designed so you can take a corner at the speed limit, people aren't trail braking into corners in their daily commutes. But you can't possibly pump brakes fast enough to mimic ABS optimum grip profiles. Pumping the brakes (or as racers call it, Brake Feathering) used to be a way to retain steering while braking. Which is the entire purpose of ABS. Because as you learned, locking the wheels causes understeer. An added benefit of feathering brakes is to create "weight transfer", which is when a car's motion is transfered to the front wheels under braking due to inertia. Grip is a function of the normal force applied to the gripping element. Weight over the tire, in simpler therms. Provided the wheels don't lock, this also increases the grip on the front tires. Racers use it to take turns at a higher speed as more grip means the car slips less thus can turn better. You shouldn't pump ABS brakes though. Most ABS Systems will understand that as an override command so you'll have to keep doing it so the wheels won't lock up.
@@bokinoki If by *modern* you mean a vehicle that was made in recent years, then you're dead wrong. My 100cc motorbike made in India in 2019 still works well with this technique. Go figure
Neel_kant I think you meant hydraulic/ air pressure based breaking systems.... cheaper vehicle like 2 wheelers still use cables to handle the breaks, they all have got Human ABS!. As you mentioned, motor bikes that have hydraulic disk breaks, if they don’t have ABS, it becomes really tricky to hit the breaks. In mountain bikes (cycle with fancy things), they call this feathering the breaks.
This video really helped me because automobile engineering is a subject in my school and some of the things our teacher taught were unclear, but after watching this video, I understood it a lot better. Also, my exams are coming soon and this video helped me to recall my memory. So wish me luck!
Actually the description is not 100% correct. This animation discripes 3 different systems as ABS. The ABS is just stopping the brakes from blocking not more ! The description for braking on a road with different surfaces or driving around a street barrier and holding the car in lane it's called ESC (Electronic Stability Control) or DSC. Also description how it works is not really correct. To hold the car in the lane on different surfaces the DSC (Drive Stability Control) is braking not blocking just one wheel at a time to hold the car in place. Also this system helps you to go around a barrier or any obstacle in your lane in a higher speed the system usually starts acting on a speed around 50km/h and prevents you car from slipping. This system (DSC) should be turned off by driving in deep snow. Because the DSC works together with the TCS (Traction Control System). The TCS prevents the wheels from continuous turning what makes you stuck in the snow. So next time you drive in deep snow find the button on your dashboard (or center console) with a DSC (or ESC, ESP) on it and push it A orange light will come on what says the car can slip now. This is ok for the moment because if you let the DSC on and drive in deep snow on the next hill you hit the gas pedal and the TCS will feel the wheels losing traction so it will bring down the motor tours and the wheels turning slower this will make you stuck in the snow!

Hi everyone. I'm Calvin M. P Sinaga. One of Automotive student in Padang State University. I just wanna say Thank you for this informative video on Anti-lock Braking Systems. It has significantly enhanced my understanding of this critical automotive technology. Your explanation of how ABS works by preventing wheel lock-up and maintaining traction, especially during emergency braking, is truly enlightening. I particularly found the segment on the relationship between tire slip angle and ABS performance to be fascinating. It's clear that this technology plays a vital role in enhancing vehicle safety. I think ABS is safety system that prevents wheel lock-up during braking. By rapidly pulsing the brakes, ABS allows the wheels to maintain some rotation, improving steering control and reducing stopping distance on slippery surfaces.
Thank you for making this video. I am studying for my driving test and this helped me understand how this system actually works. It turns out to be more important than I thought!
If anyone has doubts if this is reasonable, it totally is. The quickest team by a big margin is South Park who make 20 minutes content in 6 days. But they have far more than 4 people and far more than 60 people if you were to extrapolate it to this video. And in the case of South Park all of the moving animations most often come from existing assets already and it's mostly still backgrounds that have to be added. Having to make all these new mechanical parts and making the animations for them is what takes so much time.
The ABS actually increases the braking distance compared to braking perfectly with ABS off. However, it is very difficult to achieve and requires practise, not to mention the fact that ABS makes it easier to steer properly while braking. In the end I think ABS is a fair tradeoff between braking distance and steering capability.
There was definitely a big difference between some of the domestic manufacturers and Bosch ABS systems, my Audi A4 was much much better in the snow breaking, it seemingly new when to increase the brake pressure to make up for lost distance when ABS was triggered.
You know that rolling wheel actually have more friction than a skidding wheel IF YOU HAD clear YOUR 11 CLASS PHYSICS BACKLOGS. Therefore, reducing braking distance.
Not true. No matter how good you are at braking, under certain conditions, there will be times that one wheel may need more braking than another to most effectively reduce the car's speed. No matter how good you are at braking, you cannot choose which wheel is receiving X amount of brake pressure. So there are times where no matter what, ABS (assuming it's a solid system) will be superior to even the most trained drivers.
I would disagree, under most practical road conditions, ABS would decrease the braking distance during panic braking.. Only under hypothetical ideal conditions on paper would ABS increase the braking distance.. Dude, when u slip and slip badly, there is such a bad braking distance, which is enough to decide between life and death..
I was driving today, and had to slam on my brakes to avoid a bicyclist that came in front of me. I felt my brakes slip. I knew my car had abs but didn’t know what it what or felt like. It concerned me. Thanks for teaching me something new.
I did the same thing today. Did you have to repair anything? My abs brake system light is on, and taking it to the mechanic on Wednesday... trying to save money lol. I know your post is from 2 yrs ago, just giving this a shot..
You should be awarded for making a brilliant conceptual video on this topic. Teachers like you are the diamond which is not available every where. Thanks
The explanation of ABS is good. However, at 6:15 what is being referred to as EBD (Electronic Braking Distribution) is in fact not EBD. That is ESC (Electronic Stability Control) or a sub-function of ESC. EBD (actually Electronic Braketorque/Brakeforce Distrubution) distributes the brakeforce between front axle and rear axle. EBD does not counteract yawrate.
Thats the abilty of the transmitter and its distribution /release of pressure on individual reciever on each wheels...i forgot the instruments on each wheel ...on trailers air to open is applied to the diaphram of the brake drum the air is calibrated depending on the signal recieved by the transmitter
I have a couple of videos before on this topic. But this was the best among them. Very clear and practical. Thanks for that great videos. And waiting for such kind of videos
Great video! I learned something new today. I learned it vaguely from my dad who is a mechanic what ABS does. This in-depth explanation clears a lot on the physics of this system. The level of engineering done on this is pretty amazing. Now I know what that box near the brake fluid chamber does :)
This classic-style type of A/V presentation is always more effective in delivering information efficiently. It reminds me of Chevrolet's old video tapes! *Great Job*
I have a Honda 2012 accord and we just got hit with a heavy snow storm up in New Hampshire recently. She's a good car, and did her job when I decided to go driving the next day. Upon exiting my drive way, the ABS system kicked in, as I was turning on some slippery slush, as it should. Unfortunately, the system never turned off and has been stuck in the 'On' position since then. I took out my manual and learned how to turn it off. I have a family member who works in the automotive industry and thinks I either might have low tire fluid or a glitch in my abs system. I'll be checking it out soon, but this is a nice video seeing how it works.
quality tyres are one of the most important pieces of kit when it comes to control of the vehicle, all electronic systems depend on the tyre gripping the road
Actually, I would explain one part of the video differently (sorry for my imperfect English in advance). Static friction on same contacting surfaces is much higher then sliding friction, that is why, for example, its harder to start sliding sofa then keep it sliding when pushing, it feels like its sticked to the floor. Here, when wheels are rolling, they have static friction with ground, ABS, as explained in the video, prevents wheels from locking and by this, it allows us to keep maximum friction with the ground to reduce braking distance. Great video overall ^^
ABS is a technological marvel, It has reminded me of my old friend from high school where his first car was a 1998 Chevrolet Cavalier with a faulty ABS system. He ended up smashing a telephone pole because the roads were incredibly icy at the time and was going too fast. Lack of ABS played a big role in when he wrote that car off
Basically, how much force the wheel and surface can add to the car defines how fast the car stops. When a wheel its not slipping, it's able to deliver more force than when it is slipping.
This is a good explanation of ABS so thanks! However it skips over the whole fact that when a vehicle isn't skidding, braking comes from the transfer of the kinetic energy of the car into heat in the brake pads and not due the friction of the wheel on the ground, and this is also a factor that has to be considered with the "percentage of slippage" mentioned in the video since if your wheels have no rotational velocity they will not be rubbing across the brake pads and generating heat and losing energy that way.
they are both correct interpretations. One uses Newton's Laws of Motion with forces and the other uses conservation of energy. You can connect these two ideas by saying the frictional force is doing work on the car by converting its kinetic energy into thermal energy. Either ways saying both cases is redundant. Whether you use conservation of energy or newton's laws, in every single classical mechanics/dynamics scenario you will always come to the same conclusion.
ABS has a big flaw. Usually the intermittent action is mostly noted when raining and helps, however there have been times when I’ve been at normal speed in dry conditions and the car in front suddenly stopped, so I hit the brakes abruptly to the floor by instinct. ABS has caused the car to travel much more than what it would have if I had hit the brakes without the instinct of doing it abruptly, as I have made the test of being at the same speed and hitting the brakes normally. I always say I hate the ABS due to this fact but this video has helped me see this flaw is one of the many instances where ABS acts and more times than not it helps. I wish this issue could be looked at, perhaps releasing brake at a different or variable frequency
If you floor the brakes then i am glad you had abs with you. If a car in front of you brakes suddenly and you floor the brakes probably you will hit them without abs in a dry/wet/any condition. Especially in manual drive. So please dont disable abs for testing or for real.
@@YanYanicantbelievethistakenffs Hi. I didn’t disable them, just did the same speed (which wasn’t that fast, about 45 mph), but braking not so fast and it stopped quicker without sliding because it didn’t trigger the ABS system. The problem is, you can’t control instinct as to not floor it in an emergency. I believe ABS serve its purpose when it’s raining or there’s a puddle, but in dry conditions ABS is good only if you’re at high speed
@@thelastofyou i dont think you understand what happens when the wheels lock up, especially the front ones. ABS is a safety device. A locked wheel provides no steering, zero. If your front wheels lock up you can go sideways very very fast. If your abs hadnt been there you would have gone straight to the curb or into oncoming traffic. Disable your abs and go to an empty parking lot and slam your brakes. It will surprise you how fast your vehicle takes off to the side when the wheels lock up. Proper braking technique always stops you faster. Abs only activates when you use improper braking technique and it prevents you from losing control of the vehicle.
Same here that's why I'm looking into it. Some idiot made a left turn just in the nick of time for me to hit the brakes and I ended up within a foot or so.
When abs activates the brake vibrates, you can feel it on your foot while you are pressing the brake and you can also hear a faint sound of your brake pad grinding agains the disk every few milliseconds something like tutututututu, that way you know if you are slipping when on wet road or gravel on the road
Now I not only know how abs works but I also know why I could still steer a vehicle without abs by pulsing the brakes rather than fully pushing it at once. Thank you all.
i have seen a lot of videos from learn engineering all the them were very good, somehow i feel this one was slightly complicated by using the velocity concepts while it could have been explained in a much simpler way.. Although the complication was definitely simplified due to the visuals :) but a big thanks to these videos anyway!!
Thanks for this informational video.. Have visited my mechanic countless times..Complaining my car doesn't brake well when in high speed..I didn't know it's this ABS thing and it's advantages
ABS is really an accident-saver even on motorcycles. I had a 2003 Kawasaki ZR7S with no ABS, many times when I had to do emergency hard braking the back wheel locked up and I will do a donut fish-tailing at 50 MPH, if you did not have the experienced I had you would have crashed. Now that I have a modern bike, the Kawasaki ERN6 2017 I have ABS brakes. In the same hard braking the back wheel doesn't lock 'n slide or do donut fish-tailing. It's very safe, totally worth it!
Best man .....the best explanation 👍👍👍👍👍👍👍👍👍 very very informative....I hate mechanics specially rotational motion (during my 11th )...but your videos are building an intrest in me toward taking mechanical engineering in future.... Thanks a lot man...👍👍👍🙏🙏
In easy terms - abs prevents locking up wheels totally because that would lose steering capability. Intermittent braking instead of full braking. - the intermittent braking actually brakes better because of how rubber wheels interact with the road - abs sees if the car sways to one direction without steering and adjusts brake speed per wheel to make up for it. Hopefully it was helpful, anyway I just liked to write it down for myself too.
@@haiderali-rg1ns Or! Some of us get it faster than others........ or without certain tidbits having to be explicitly spelled out considering everything else. Praising blindly... like you're some unsung genius
Abs doesn’t reduce breaking distance , a good driver that brakes to the limit have a shorter braking distance. Abs avoid wheel locking when you brake over that limit , but it’s absolute not shorter .
@@aleksandersuur9475 Depend from were you are , but i would by very happy to show you ! But lets erase the first myth about ABS , its not build to make you stop quicker , its made so you tires doesn't lock, so you can avoid a obstacle and can maneuver your vehicle , no way you stop quicker !
Slight nitpick, normal braking doesn't lock up the wheels, you slow the car down with the friction of the brake pads on the wheels and there should be no slip against the road still.
5:40 love how this clip just seems to throw newton's laws of motion right out the window, most notably the one that describes the conservation of momentum.... if you have a 1-2 tonne vehicle sitting on top of these 4 rubber tires hammering on the breaks isn't going to make the vehicle accelerate even upon slippage
when you take something quite simple and explain it in the most complicated way, so complicated that even those who know this stuff will not be able to understand the explanation = ^^^
IamIUareU it’s explained very simply, it literally is broken down into the most simple form available. What were you expecting? “ABS switches your brake pads on and off”, why did you even watch this video?
Seraph909 Person A: You took something complicated and explained it in a complicated way Person B: You are wrong, they explained it simply Person C: That’s bs, ABS doesn’t work like that! Do you now understand the importance of reading something before you post?
I respected ABS one time when the right side wheels got in contact with wet surface while the left was dry... Without them I would have probably spinned..... I was going at 120km/hour
Abs had nothing to do with it if you didnt hit break, and if you did break at that point please take another driving lessons or at least take some "safe drive" course online or something like that before you kill yourself or even worse someone else 🤗
Thank you teacher for informasion,🙏🙏🙏 ABS or Anti-lock Braking System is a very important safety feature in motorized vehicles, including motorbikes. The ABS brake system is designed to prevent the vehicle's wheels from locking during sudden braking, so that the driver can still control the vehicle properly
Engineers who solve these problems are amazing.
Proud to be one of them.

perfect sliding is actually almost always at a lower frictional coefficient than "beginning to slide". This applies even to a smooth block of brick.

This is refreshing for me, as someone who used to work in a manufacturing assembly of speed sensors.
I've been watching your vids lately and honestly I feel smarter
Genius way of teaching. Should start doing fundamentals.

The part of explanation of negative acceleration is the best. Great video. Huge thanks from Armenia
I came for building 6-pack abs, stumbled upon this wrong video, and gained new knowledge on different abs. Thank you.
The explanation is just wow!!!! It amazes me how such concept is easily explained in this video,.. salute to you guys..
Great video! I learned something new today. I learned it vaguely from my dad who is a mechanic what ABS does. This in-depth explanation clears a lot on the physics of this system. The level of engineering done on this is pretty amazing. Now I know what that box near the brake fluid chamber does :)
This classic-style type of A/V presentation is always more effective in delivering information efficiently. It reminds me of Chevrolet's old video tapes!
*Great Job*
Yes. This technology saved my life last year...... When due to fog I was just about to meet an accident.....
Wow I was prepping for my theory exam and was wondering how ABS worked, this is SOOOOO cool and genius!
What theory exam asks you how ABS works?
I have a Honda 2012 accord and we just got hit with a heavy snow storm up in New Hampshire recently. She's a good car, and did her job when I decided to go driving the next day. Upon exiting my drive way, the ABS system kicked in, as I was turning on some slippery slush, as it should. Unfortunately, the system never turned off and has been stuck in the 'On' position since then. I took out my manual and learned how to turn it off. I have a family member who works in the automotive industry and thinks I either might have low tire fluid or a glitch in my abs system. I'll be checking it out soon, but this is a nice video seeing how it works.

Was wondering 😂😂😂
The absolute last of your worries
tch..women drivers
Hahaha
Puch break without clutch is much better
Thank you very much. WHen I was a university student there were no such learning aids. This would have helped me a lot.
quality tyres are one of the most important pieces of kit when it comes to control of the vehicle, all electronic systems depend on the tyre gripping the road
Well are the electronic systems themselves not more important?
All the physics i learnt in the high school summarized✔️💯
So this is what saved both my life and my car from crashing, Thanks for the informative video

Your channel is one of the best💪👏👏
Perfect…this is the best explanation on ABS functional and its fundamental…
Super video sir
I am an engineering student this video is so much useful with us sir.
Actually, I would explain one part of the video differently (sorry for my imperfect English in advance). Static friction on same contacting surfaces is much higher then sliding friction, that is why, for example, its harder to start sliding sofa then keep it sliding when pushing, it feels like its sticked to the floor. Here, when wheels are rolling, they have static friction with ground, ABS, as explained in the video, prevents wheels from locking and by this, it allows us to keep maximum friction with the ground to reduce braking distance. Great video overall ^^
Yeah he said friction during pure rolling is 0 which is not true, there can't be any rolling without friction.
ABS is a technological marvel, It has reminded me of my old friend from high school where his first car was a 1998 Chevrolet Cavalier with a faulty ABS system. He ended up smashing a telephone pole because the roads were incredibly icy at the time and was going too fast. Lack of ABS played a big role in when he wrote that car off

you explained ABS very well .i give you 5 stars
And thus the solution of slapping computational power into the problem reveals itself. Great series, BTW.
Basically, how much force the wheel and surface can add to the car defines how fast the car stops.
When a wheel its not slipping, it's able to deliver more force than when it is slipping.
This is a good explanation of ABS so thanks! However it skips over the whole fact that when a vehicle isn't skidding, braking comes from the transfer of the kinetic energy of the car into heat in the brake pads and not due the friction of the wheel on the ground, and this is also a factor that has to be considered with the "percentage of slippage" mentioned in the video since if your wheels have no rotational velocity they will not be rubbing across the brake pads and generating heat and losing energy that way.
they are both correct interpretations. One uses Newton's Laws of Motion with forces and the other uses conservation of energy. You can connect these two ideas by saying the frictional force is doing work on the car by converting its kinetic energy into thermal energy.
Either ways saying both cases is redundant. Whether you use conservation of energy or newton's laws, in every single classical mechanics/dynamics scenario you will always come to the same conclusion.

Without the ABS tho
It's not funny when she crash with abs on
You Cant Drift with the ABS on.
I know its a year late but its actually Traction Control that comes to mainplay for drifting while ABS helps a big deal in it too.
ABS has a big flaw. Usually the intermittent action is mostly noted when raining and helps, however there have been times when I’ve been at normal speed in dry conditions and the car in front suddenly stopped, so I hit the brakes abruptly to the floor by instinct. ABS has caused the car to travel much more than what it would have if I had hit the brakes without the instinct of doing it abruptly, as I have made the test of being at the same speed and hitting the brakes normally. I always say I hate the ABS due to this fact but this video has helped me see this flaw is one of the many instances where ABS acts and more times than not it helps. I wish this issue could be looked at, perhaps releasing brake at a different or variable frequency
If you floor the brakes then i am glad you had abs with you.
If a car in front of you brakes suddenly and you floor the brakes probably you will hit them without abs in a dry/wet/any condition. Especially in manual drive.
So please dont disable abs for testing or for real.
@@YanYanicantbelievethistakenffs Hi. I didn’t disable them, just did the same speed (which wasn’t that fast, about 45 mph), but braking not so fast and it stopped quicker without sliding because it didn’t trigger the ABS system. The problem is, you can’t control instinct as to not floor it in an emergency. I believe ABS serve its purpose when it’s raining or there’s a puddle, but in dry conditions ABS is good only if you’re at high speed
@@thelastofyou i dont think you understand what happens when the wheels lock up, especially the front ones. ABS is a safety device. A locked wheel provides no steering, zero. If your front wheels lock up you can go sideways very very fast. If your abs hadnt been there you would have gone straight to the curb or into oncoming traffic.
Disable your abs and go to an empty parking lot and slam your brakes. It will surprise you how fast your vehicle takes off to the side when the wheels lock up.
Proper braking technique always stops you faster. Abs only activates when you use improper braking technique and it prevents you from losing control of the vehicle.
Fantastic explanation about ABS. A lot of information in only 6 mins.

Omg! Abs saved my life today!
Same here that's why I'm looking into it. Some idiot made a left turn just in the nick of time for me to hit the brakes and I ended up within a foot or so.
@@ThePeterDislikeShow it's the air bag that's going to save you, not the ABS.
Wow! This is thoroughly and easily explained. Great video! Thanks for sharing!
When abs activates the brake vibrates, you can feel it on your foot while you are pressing the brake and you can also hear a faint sound of your brake pad grinding agains the disk every few milliseconds something like tutututututu, that way you know if you are slipping when on wet road or gravel on the road
That's very true
Simply explained. Even non engineering minds can benefit a lot from this. Thank u so much
After several years my jeep's ABS system is finally back to normal
Now I not only know how abs works but I also know why I could still steer a vehicle without abs by pulsing the brakes rather than fully pushing it at once. Thank you all.
Add about front axles and and its type. Please add the video before 1st Dec (it will provide me a great help for my exam).
Awesome way of learning 👍
i have seen a lot of videos from learn engineering all the them were very good, somehow i feel this one was slightly complicated by using the velocity concepts while it could have been explained in a much simpler way.. Although the complication was definitely simplified due to the visuals :) but a big thanks to these videos anyway!!
Amazing video, very informative even for an engineer!
Another nice video. You haven't posted for a long time, but it was worth it.
Thanks for this informational video.. Have visited my mechanic countless times..Complaining my car doesn't brake well when in high speed..I didn't know it's this ABS thing and it's advantages
ABS is really an accident-saver even on motorcycles. I had a 2003 Kawasaki ZR7S with no ABS, many times when I had to do emergency hard braking the back wheel locked up and I will do a donut fish-tailing at 50 MPH, if you did not have the experienced I had you would have crashed. Now that I have a modern bike, the Kawasaki ERN6 2017 I have ABS brakes. In the same hard braking the back wheel doesn't lock 'n slide or do donut fish-tailing. It's very safe, totally worth it!
In simple terms, ABS prevents the wheels from locking up so you don't skid.
Best man .....the best explanation 👍👍👍👍👍👍👍👍👍 very very informative....I hate mechanics specially rotational motion (during my 11th )...but your videos are building an intrest in me toward taking mechanical engineering in future....
Thanks a lot man...👍👍👍🙏🙏
Thought I knew a bit about abs but now I'm even more confused
In easy terms
- abs prevents locking up wheels totally because that would lose steering capability. Intermittent braking instead of full braking.
- the intermittent braking actually brakes better because of how rubber wheels interact with the road
- abs sees if the car sways to one direction without steering and adjusts brake speed per wheel to make up for it.
Hopefully it was helpful, anyway I just liked to write it down for myself too.
Exactly...this video making more confused. I do not why...few people praising blindly.
@@haiderali-rg1ns Or! Some of us get it faster than others........ or without certain tidbits having to be explicitly spelled out considering everything else.
Praising blindly... like you're some unsung genius
Don’t worry , just press brake pedal and don’t think about what’s going under your foot
This is a straight up fantastic explanation!
Very simple and easy to understand! Keep on doing this type of video again😁👍
Abs doesn’t reduce breaking distance , a good driver that brakes to the limit have a shorter braking distance. Abs avoid wheel locking when you brake over that limit , but it’s absolute not shorter .
Exactly
You mean using brake pads friction to slow down cars, but not too much to stop the wheels
I would very much like to see that mythical "good driver" that can outperform ABS, surely this can be demonstrated in an actual breaking test, yes?
@@aleksandersuur9475 Depend from were you are , but i would by very happy to show you ! But lets erase the first myth about ABS , its not build to make you stop quicker , its made so you tires doesn't lock, so you can avoid a obstacle and can maneuver your vehicle , no way you stop quicker !
@@aleksandersuur9475 you can find vids on YT
Slight nitpick, normal braking doesn't lock up the wheels, you slow the car down with the friction of the brake pads on the wheels and there should be no slip against the road still.
Its just like the "anti-skidding system" on aircraft's
Now say that in the short form
Amazing. Every days is a new lesson. thanks for sharing!
I understand it completely! People are devolving at such an incredible rate that they can no longer be taught how to drive a car
“You still dont understand do you?”
“That eight six has human abs”
"After all, ABS can't outperform the right foot of a highly experienced driver like him"
"You can't figure out how to properly use ABS until you've mastered braking without it. That's the Toudou school's rule."
I like how he put a women in the car just to make the whole accident thing more realistic.

5:40 love how this clip just seems to throw newton's laws of motion right out the window, most notably the one that describes the conservation of momentum.... if you have a 1-2 tonne vehicle sitting on top of these 4 rubber tires hammering on the breaks isn't going to make the vehicle accelerate even upon slippage
What are you talking about ? The video didnt state the vehicle accelerated after slippage
Brilliant video!
Very useful video...now i know what ABS means & how it works, & how it safely save lives &/or reduce fatal car accidents... thank you...
when you take something quite simple and explain it in the most complicated way, so complicated that even those who know this stuff will not be able to understand the explanation = ^^^
IamIUareU thank you. I was thinking the same thing.
He wasn't explaining ABS, he was explaining principles behind ABS.
IamIUareU it’s explained very simply, it literally is broken down into the most simple form available. What were you expecting? “ABS switches your brake pads on and off”, why did you even watch this video?
Seraph909
Person A: You took something complicated and explained it in a complicated way
Person B: You are wrong, they explained it simply
Person C: That’s bs, ABS doesn’t work like that!
Do you now understand the importance of reading something before you post?
A=Anti
B=Block
S=Sistem
I respected ABS one time when the right side wheels got in contact with wet surface while the left was dry... Without them I would have probably spinned..... I was going at 120km/hour
Abs had nothing to do with it if you didnt hit break, and if you did break at that point please take another driving lessons or at least take some "safe drive" course online or something like that before you kill yourself or even worse someone else 🤗

@@duxgaming9985 Agreed)(
Thank you teacher for informasion,🙏🙏🙏
ABS or Anti-lock Braking System is a very important safety feature in motorized vehicles, including motorbikes. The ABS brake system is designed to prevent the vehicle's wheels from locking during sudden braking, so that the driver can still control the vehicle properly
Disconnected mine on my 1997 Chevy Silverado the day i bought the truck.23yrs later,with 437000 k's on her.I still feel safe driving without the ABS.
love from bangladesh , love learning this
