The 180kg force is a bit misleading. The force they use is not just them pushing on the pedal, it is heavily influenced by the G-forces in play. So it is more like holding three times their bodyweight, it is not pushing 3 people off the ground with one leg. And they rarely hit the maximum. But even when you take away the misleading statements, it is still a hell of a lot of force they have to exert and they need to do that for 90 minutes. I wish they stopped saying that it takes X kg when that X kg isn't all done by the driver and when that X kg is done once in the whole fucking season... It just gives the wrong idea. The truth here is easily impressive enough: you or i will not be able to the same. We might have enough strength to push that pedal to about what it needs but we will not be able to do it multiple times in succession. About a decade ago i could've probably hold two people and take a step or two, and then my legs would've just given up. It is the amount of repetition they are able to do at around 90-120kg and still have great precision that is really impressive, and they do not have massive legs either. It is very compact strength.
Yes - the forces at play make a difference. The impressive bit is the fine modulation a driver is able to make under very high loads. I think of it in terms of "work" - the work load is still incredibly high regardless of G. That an F1 driver can do this consistently for a whole race is is more than impressive
I can't say you are completely wrong because there are subtleties to this. However, the whole load into the pedal is through the driver's leg and foot so he is pushing/supporting up to 180kgf, the exertion is the same. G is a big factor but the driver position means the seat, steering wheel and belts play their part in load distribution too (kitted driver of 80kg at 6g is about 470kgf)
@@ColinCarFanthere's some physics at play I don't fully understand to be fair, but I don't think the brake force comes for 'free'. The driver has to use a lot of force (how much I don't know), maintain that force and trail off in a controlled manner. The telemetry records the brake input in terms of hydraulic pressure, too - so how to get from one to the other I'm not sure. But we're not disagreeing for sure. And whatever the load may be, I'm pretty sure I could handle a few corners before I couldn't do it anymore!

I was very fortunate and got a paddock pass in Austin. During the Aston Martin garage tour they mentioned that the brake pads are $20k-$25k each and that they replace them once a day. So that's over a quarter of a million just on brake pads for a race weekend.
Wait a second: 25k each means 50k per wheel, means 200k for the whole car, means more than a full million for both cars for a race weekend. And that means roughly 300 millions for all teams combined over a full season. If we include the pre-season tests, then we talk about half a billion. That s a whole industry living just on F1 brake pads.
I learned from a mentour pilot video awhile ago that the wear factor of steel brakes is the hardness of application, but the wear factor of carbon brakes is the number of applications. Carbon brakes favor fewer, harder applications, which seems very good for racing.
I watch a lot of channels that do interviews, and the commentator will add narrative to explain something, maybe in more simple terms, or to explain something more fully. This video the narration seems to just repeat the information with no real reason.
The bit you forgot: BREMBO F1-INFOGRAPHICS - THE BRAKE PADS "The friction material used for Brembo pads has gone through significant changes. The actual material used, known as CER, has significantly reduced wear and guaranteed a more effective thermal conductivity. Compared to the previous composite, CER ensures excellent warm-up time, namely speed in reaching the maximum operating temperature for greater effciency, broad range of use, both in terms of pressure and temperature, and linear brake response. These are all features that allow the driver perfect modulation of the brake system. Incredibly low wear that means constant pedal stiff and performance throw the race. The material used for all Brembo discs is the same for all teams. During a complete season, Brembo provides each team, consisting of two cars, an average from 280 to 480 pads." The pads themselves look like big curved slabs of ~inch-thick carbon-carbon.
Scott, I'd love to see an episode about the telemetry and driver/team communication systems between the cars, pit wall and factory. What do the radios look like, what sensor data are uplinked, how is it processed and displayed to the teams, what comms are done in the background (i.e. without driver knowledge) and which are done via voice and require driver action. Thanks for the great content!
Wait! So, you press this pedal, it moves a piston in a master cylinder filled with fluid, and that activates a clamping motion in the pad. F1 really has done some crazy science fiction stuff there!
That's pascal's principle and it's used widely in all cars f1 or street cars sports or sedans Hydraulic Pressure through the braking pad to a cylinder of Hydraulic fluid generating higher force on smaller area using the same amount of force you do on a larger area on the fluid So if you press with force of 5N on the brakes The work you done for it gets multiplied on the brakes to like 10N due to the area being lower in the fluid pistons U can look up Hydraulic press mechanism of working or pascal's principle It's not that big of a deal here The impressive thing is the Braking discs and its high temp resistance and effectiveness

@@Julian-ty2ps that doesn’t literally mean there’s a wire. That just means that the pedal isn’t directly connected to the calipers. They literally explain that it’s all using hydraulic pressure, just like a road car. The “by wire” part means that there’s an element of electronic control in the middle.
I'm most impressed by you knowing the difference between less and fewer. Pretty much all the content creators I hear online these days use less when they should use fewer. The other thing that bugs me is people using the non-existent word exetra, when they should be saying et cetera.
my friend's husband worked many years as a braking consultant for one certain Italian racing team and gave me a limited tour of the team's facilities ... mind blowing how complex an f1 team operation really is ..
Look, the 180 kg of pressure needed to actuate a F1 break sounds impressive, but everyone who lift weights knows that there must be some major information missing. Look up a person deadlifting 380 kg and compare them to a f1 driver. Something ain’t adding up!
Go to a gym, find a leg press machine and put on 180kg of weights and with just your left leg, using just the base of the foot at the edge of the footrest, apply up and down pressure and do it for 2 minutes and come back and tell us how it went
f1 drivers are essentially laying on their backs. when they put THEIR effort into the pedal, the stopping forces push them harder into the pedal. as the adage goes "stand on the brakes", f1 drivers actually are doing just that.
Also the drivers use deceleration itself to increase the break pressure. It’s more like holding a180kg weight pushed, it’s difficult but not impossible for regular gym person to do so. But doing so 10 times per lap for 60 laps is the main issue
It's truly amazing how these brake systems work. The pressure the driver has to apply defies logic.......... especially when you factor in how many times they apply the brakes. Countering fatigue during the race must be a nightmare.
I am pretty sure it's like on a motorcycle, you hold the rear brake while releasing the front more to get the roration, in this case it might obey some control laws set by engineers, and input all by drivers.
I met Jim Hall, of Chaparral Fame, and apparently he is credited with using the car’s shape to create downforce. Him, being an engineer, hired two engineers from Convair aircraft corporation. Johnny Rutherford won one of his Indy 500 races in a Chaparral.
I understand that Esteban wants a heavy spring. Of course the drivers are not pushing with 180kg of force everytime they break. They would rival indoor cyclist with their legs. But when braking the deceleration also pulls on the leg and pedal so with every step it increases, so does the help you get. And that's probably why Esteban likes a firmer spring, so that on hard and sudden deceleration the brake feel remains as consistent as possible
Brakes are the most impressive system at any car, they handle so much, they are more fascinating than any car engine. It is interesting how long it takes to accelerate to like 200mph and how short it takes to brake down the car to a stop.
Brakes are one F1 element, like tyres, that a team cannot modify. Brembo kits each with a identical product which cant be modified. Even the oil in the hydraulics is specified. Air ducting to cool brakes is a critical design element and can also be an aero downforce element usually combined with front wing flow. They dont want ducting to impede flow and create excess drag.
I had a question about brakes I hope someone can answer: smaller master cylinder piston makes for more final brake pressure but a larger master cylinder piston makes for more responsiveness and more initial bite. So what would be the ideal master cylinder size ?
Don't get me wrong, at 1:15, if the second car can brake 10m later is mostly because of better tire grip, not brake necessarily. But that would be more agressive with the heat on the brakes, so is better to have a brake system that can manage that heat. It may apear intrinsic, but if you are at the limit of the tire, better brakes won't make difference on the deceleration ratio, or distance. However, considering the tire heat management that F1 brakes also affect, that is realy clever.
Braking is actually much more important than lap times! The vast majority of passes are made under braking. Even just in that example - if you brake at 100m, and I brake at 90m, then I already passed you!
Just to reiterate the braking pedal force - 180kg might mean a lot but you're already holding 70-80kg if you just stand on one leg, so the distance to 180kg isn't that long. Also, these brake pedals don't have much travel, you can really push on it with whole your body and not move much in your seat. I reckon braking isn't something the driver does with his ankle movement, but rather a whole body effort - literally standing on the brake. Counterintuitively, it allows for much finer modulation.
BRILLIANT VIDEO! Thank you for making such a great video! really great visuals and fantastic information presented in a very pleasing manner. Thank you!!!!
I have 371mm front and 365mm rear floating rotors on my Corvette C7. Brembo calibers as well. Each wheel brake is independently pressurized and controlled by the ECU and a servo manifold. Just wanted to brag. 😆
Hey up mate did the thing's you requested. Really good video haven't seen you before, i like your breaking fella its sweet hearing from someone at the top ov a box
It's fun to think about how all of the electronic programing that makes all of this possible, is basically just a computer reading a spreadsheet. Pretty neat
I found this very interesting indeed, thanks, in particular the harvesting energy and balance operation. You also got 'deep dive' into the narrative twice, great for anyone playing Buzzword Bingo. Blue Sky thinking is so yesterday!
I need a clarification the force needed to apply to the pedal ,we talking about if you need push the pedal all the way down or is the force you need to apply every time you use the pedal ...
The forward G force also helps them push the brakes…. Still absolutely insane! I remember a video where a “normal driver” hit the brakes as hard as he could from 100mph in an F1 car into a corner… and the team said he was only at like 20% braking 😳😳😳😳
these drivers were literally strapped into their cars, like they can barely move their necks to use the side mirrors. there is no forward motion from their body to help with braking. experiencing that kind of motion in various weather conditions and for almost 2 hours is suicidal
As a newer fan, started watching after Lewis got robbed and have always wondered how the brakes actually work cause all I see is a big drum. This is awesome thanks🎉
I don't have engineering Job Scott. I don't have an engineering background or to fill up my CV with engineering stuff and knowhow. I don't have engineering diploma. But damn am I interested in how something complex and comprehensive works. So to answer your question... Yes do keep these videos coming with proper explanations like in this video with the people who worked on those things and know exactly what's the designs intention and purpose.
Robert Linton is having Lithium Aluminum brakes made for his America GS 964 Porshce. ( he has the only America GS ever made) it’s incredible.. like.. beyond what Porsche is capable of..kinda
With 6 G's of deceleration, the mass of the driver's leg adds considerably to the brake pedal force. So he doesn't actually have to apply 400 lbs of force. If, for example, a leg is 50 lbs, at 6 G it's applying 300 lbs all by itself, the driver adding the necessary extra 100 lbs. It's like power brakes!
4:18 "That spring sits here" *shows an animated diagram with 8 different parts circled and labeled and no spring in sight* Me: "I'm sure it's... somewhere in there"
Interesting about the impressive pedal forces leadingto better feel and feedback. I recall reading years ago about Blue Angelsprecision flying team, having control stick set to require constant 50lbs of force just to hold it steady. Reason stated was it improves precision required of pilots. Same concept it seems.
driving 4 answers did a video a while back, about how larger discs don't actually stop you faster. but this F1 engineer says they do. intuitively, he seems right about leverage: for a given brake pad surface area and pressure applied, farther distance from the axle would seem to give an advantage. i can't remember d4a's reasoning, but am curious about any input here.

Don't get me wrong, at 1:15, if the second car can brake 10m later is mostly because of better tire grip, not brake necessarily. But that would be more agressive with the heat on the brakes, so is better to have a brake system that can manage that heat. It may apear intrinsic, but if you are at the limit of the tire, better brakes won't make difference on the deceleration ratio, or distance. However, considering the tire heat management that F1 brakes also affect, that is realy clever.
Do formula one utilize the ABS system
Love these videos that dive into the tech side of F1!
Braking is actually much more important than lap times! The vast majority of passes are made under braking. Even just in that example - if you brake at 100m, and I brake at 90m, then I already passed you!
I immediately remember Mario Andretti quoted saying "drivers still think the brakes are for slowing the car down".
Well no, it depends where the cars are to each other.
You watched the video then...
2:58 Im gonna need picture proof
“Why brakes are so important in F1” it’s kind obvious, when u are at 355 km/h the most important thing is the brake.
Such an interesting video. One of the best f1 channels on yt. 👍
Stevens _looks_ young and like he just stepped out of bed. Love the vibe.
It really is hard to explain with so much secret stuff, but still interesting. Thanks for the video.
Great video, as always. I love the technical stuff. Keep it coming! 👍🏻🤘🏻
You're incredible, don't stop creating videos!
Ryan, stop the genger videos ?
Do they not use brake pads? This implies that the caliper pistons actually are rubbing on the brake rotor. Or did I miss that??
Just to reiterate the braking pedal force - 180kg might mean a lot but you're already holding 70-80kg if you just stand on one leg, so the distance to 180kg isn't that long. Also, these brake pedals don't have much travel, you can really push on it with whole your body and not move much in your seat. I reckon braking isn't something the driver does with his ankle movement, but rather a whole body effort - literally standing on the brake. Counterintuitively, it allows for much finer modulation.
BRILLIANT VIDEO! Thank you for making such a great video! really great visuals and fantastic information presented in a very pleasing manner. Thank you!!!!
I have 371mm front and 365mm rear floating rotors on my Corvette C7. Brembo calibers as well. Each wheel brake is independently pressurized and controlled by the ECU and a servo manifold. Just wanted to brag. 😆
where is the owen wilson meme when you need it.
Brag when all you could get was a Vette? Let the internet know when you can afford a Porsche 911.
@@ronbelanger4113 Why would I want a 911? C7 Zo6 will destroy an overpriced stretched out beetle. My vette will definitely out brake that car.
@@Bailey-k2j😂😂😂😂😂😂😂😂😂
You wish.. you have a fast tractor with low body.
There is nothing that I am more interested in than aerodynamics.
Very much looking forward to the other videos in this series. Great content as always
Alpine
Al, like the name- pine like the tree.
Hopefully now you'll be able to say it correctly.🙏🙏🙏
Hey up mate did the thing's you requested. Really good video haven't seen you before, i like your breaking fella its sweet hearing from someone at the top ov a box
It's fun to think about how all of the electronic programing that makes all of this possible, is basically just a computer reading a spreadsheet. Pretty neat
I found this very interesting indeed, thanks, in particular the harvesting energy and balance operation. You also got 'deep dive' into the narrative twice, great for anyone playing Buzzword Bingo. Blue Sky thinking is so
yesterday!
I need a clarification the force needed to apply to the pedal ,we talking about if you need push the pedal all the way down or is the force you need to apply every time you use the pedal ...
The forward G force also helps them push the brakes…. Still absolutely insane! I remember a video where a “normal driver” hit the brakes as hard as he could from 100mph in an F1 car into a corner… and the team said he was only at like 20% braking 😳😳😳😳
these drivers were literally strapped into their cars, like they can barely move their necks to use the side mirrors. there is no forward motion from their body to help with braking. experiencing that kind of motion in various weather conditions and for almost 2 hours is suicidal
Alpine dude got some brains.
I second the sentiment of others: The Alpine engineer is great a presenter/teacher! Concise, collected and calm.
As a newer fan, started watching after Lewis got robbed and have always wondered how the brakes actually work cause all I see is a big drum. This is awesome thanks🎉
F16s use floating carbon discs but have multiple rotors that are squeezed together. Similar yet different systems.
I don't have engineering Job Scott. I don't have an engineering background or to fill up my CV with engineering stuff and knowhow. I don't have engineering diploma.
But damn am I interested in how something complex and comprehensive works. So to answer your question... Yes do keep these videos coming with proper explanations like in this video with the people who worked on those things and know exactly what's the designs intention and purpose.
Robert Linton is having Lithium Aluminum brakes made for his America GS 964 Porshce. ( he has the only America GS ever made) it’s incredible.. like.. beyond what Porsche is capable of..kinda
With 6 G's of deceleration, the mass of the driver's leg adds considerably to the brake pedal force. So he doesn't actually have to apply 400 lbs of force. If, for example, a leg is 50 lbs, at 6 G it's applying 300 lbs all by itself, the driver adding the necessary extra 100 lbs. It's like power brakes!
5:24 he realises he's British so he stops himself from saying ''back'' and opts to say ''rear''
Alpine finally getting good publicity
What are the brake pads made from, and how much do they cost per set, do they last a whole race?
7:52 it's aluminum-lithium alloy. Pretty common in aerospace, and used in F1 brake calipers.
4:18 "That spring sits here"
*shows an animated diagram with 8 different parts circled and labeled and no spring in sight*
Me: "I'm sure it's... somewhere in there"
0:39 One man fridge is another's minibar!
Interesting about the impressive pedal forces leadingto better feel and feedback.
I recall reading years ago about Blue Angelsprecision flying team, having control stick set to require constant 50lbs of force just to hold it steady. Reason stated was it improves precision required of pilots.
Same concept it seems.
driving 4 answers did a video a while back, about how larger discs don't actually stop you faster. but this F1 engineer says they do. intuitively, he seems right about leverage: for a given brake pad surface area and pressure applied, farther distance from the axle would seem to give an advantage. i can't remember d4a's reasoning, but am curious about any input here.
That caliper is a beauty!
