These F1 Brakes cost over £50’000 per corner hit over 1000 degree Celcius and slow an F1 car at over 6G - which means 200mph - 40mph in just 4 seconds!
So, why do they cost 100X more than these Brakes from a regular road car? And why do they only last 250 miles?

Before we break down the exotic materials and why these F1 brakes cost so much, we need to understand the insane forces involved and the extreme power these things have.
For a long time in F1 the limiting factor for braking was the grip available from the tyres - so the brakes were pretty similar to those from a road car. For example, in the 60s they were using steel discs - not too different from these road car brakes.
However, tyres are now so advanced and F1 cars produce so much downforce - and therefore grip - that the brakes are subjected to monumental loads and temperatures.
The braking phase is also absolutely crucial to lap time, so if you can brake later than your competitors - you will have a big advantage. And so teams spend around half a million pounds per year on the best quality discs and pads.
All meaning that F1 cars can produce over 6G when braking - to put this more clearly, the F1 car produces three times the braking force of a McLaren Senna when stopping from 200mph.

Isn't this engineering incredible? It was awesome to be able to show you just how incredible these things are!
You really should join us for the chat with @Tommo at 8PM GMT tonight, and @Jaaames tomorrow at 7PM GMT!

Yes
How many sets of brakes do f1 teams use on one car over a weekend? And do they use old sets during the practice sessions?
what it's incredible is people using stupid measurement units like miles
PLEASE NO MORE MUSIC .
I was hoping to see some footage of the manufacturing of C/C f1 disks, the videos we see are from SiC brake discs...or is the only difference that silicium isn’t added at the end by infiltration ?
In conclusion, every F1 parts are crazy expensive
Yeah, almost same with my house price at one main part 😂
Just like airliners, and aviation industry.
@@UltimateAlgorithm There is a lot of similarity between aerospace manufacturing and F1 manufacturing. That's where most of the cost goes, manufacturing and R&D costs.
And crazy effective 💯
E X O T I C M A T E R I A L S
I need these brakes for my '99 Ranger. I hope they're in stock at Auto Zone.
Dont tell us your life live it
Ford fucking ranger.
Someone supposedly got Sachs F1 clutch from Amazon while ordering one for his (Sacsh OEM clutch) BMW. Maybe you'll get lucky. :P
cringe
Get it in the zone 🤣🤣😅
Every time they ask a former F2 driver about their first F1 testing experience they're like "Yeah, the acceleration is better, cornering speeds are much higher, but fucking hell, these brakes, man"!
Is that George Russell's interview with matt from wtf1?
1:00 Also applies to trains. Since trains (mostly) have a safety limited top speed, braking as late as possible can gain huge amounts of time if the train is late.
Without knowing for sure how try this is, I find it interesting taking in to account how long it takes for a train to break. Up to actual kilometers, if I remember correctly.
So as opposed to an F1 car where all of this happens in fractions of seconds and late breaking may be a few tenths later. I imagine In a train "late" could be anywhere from seconds to almost a minute later, depending on weight, ect.
That's a neat thought.
🎩👌
Trains have so much less grip available, though
@@counterfit5 yeah, of course. It's just all on a completely different scale, right?
this is easily solved by giving trains a bit of margin time between stations. If the train is late for any reason, it can just accelerate a bit.
@@migueeeelet
...
_No._
_They should obviously have rockets so they can rocket drift corners._
_Get your sensible opinion out of here!_
No, of course. That would make sense. I'm pretty sure that's how it is in a lot of cases.
05:22 "I'll just take a nap quickly"
Hahahaha noice
Power nap
LOL
😭😭😭
Thanks for the great video. I did some math from my break test video that you had featured :D I had the 66kw motor full throttle about 55 seconds there sending all power to one brake. So if take some drive train losses and take the fact into account that motor wasn't on best rpm area all the time and use 50kw as an average power sent to the wheel we get about 2.7 MJ of energy to explode one small steel disc brake. Of course you are not going brake constantly for one minute so in real life you could probably dump even more energy there since it would be spread for longer time.
And after doing that I spotted that you should have kilojoules there instead of megajoules on your results. But it seems that you could stop a car from over 200km/h with just one brake disc with out it exploding :D Even without taking air resistance into account. Also the simulated wheel speed on the test was probably bit over 200km/h since open diff multiplies the speed by two when you have only one wheel spinning.
So awesome to see you here!
Man u r smart !
What's up? Driver61 was calculating on 200 mph and you are doing math on 200 km/h? So - no entiende señor ?
Where did you get 200km/h from? He said 200 mph/ 321km/h.
@@carl8790 It doesnt matter. I did the math for those Golf braking from 70mph to 0 and it equals to 734115 Joules energy, wich is 1000 times less than 734 mega joules mentioned in the video
I was able to hold an F1 brake disc at the 2012 Canadian GP and I was blown away at how light it was.
Everything from a f1 car its made out of light material, except the engine
@@snifey7694 technically the engines are too. Aluminum is a light weight material in comparison to steel or cast iron. The V8s were just 95 kg, and they could have been lighter but the rules enforced a minimum weight.
correction:
@1:46 energy will be 734 KJ instead of MJ.😅
Noticed that too lol
Powerplant levels of energy? hmmmm.
I was gonna say. Those breaks would be hotter than the surface of the sun.
And 380% equals 6 times 🤔
5:22 this dude tho
LOL yeah that was funny to watch.
Lmao thought he passed out
she's a woman and the worker there did not strap her harness properly on her. could have broken her neck tho. really dangerous
@@ofuets if she didnt have something to stop her head then yes
how would you think that this is a guy
When he said "Ł50k per corner", I thought racetrack corner.
High customization + low volume production = $$$$$$$$$$$$$$$$$
You forgot the R&D costs, those make the most of the price.
17$? :D

*Sebastian Vettel Monza 2020 fiercely sweating*
Great video. Been turning wrenches for decades but have a better understanding of this system. Thank you for the video.
It’s all fun and games until the brakes on my 06 corolla start turning bright red too :/
thats why f1s dont have wheel housings, gotta have maximum air cooled tires
Can you continue your driving style videos ? Would love to see you analysing Vettel's driving style
Inb4 ice driving fish tail sbinalla joke.
Daniel ric would also be interesting with his late braking
Yeah!
Summary: spinnala
Vette's driving style is easy.
He turns, spins and moans
I’m confused about the video. Firstly, does “£50,000 per corner” mean they actually cost £200,000 since there are 4 corners of the car?
Secondly, why does it say “£5,000” and not “£50,000” at 0:21?
And lastly, you said “6 times the force” at 2:01, but 2832/734 is only 3.86 times?
^this.
I think this video is a reuploaded video. I remember he did a video on this before which is why I think it has a lot of the same content in it.
concerning the last issue:
The F1 car has to eliminate ~3 times the energy but does this in about half the time --> 6 times the force
@@LoneStarr1979 so maybe he misspoke then when he referred to energy instead of force?
I've been fan of F1 since my childhood really but your videos still make me open my mouth wide open, so much things and facts I didn't know about, thank you!
The majority of road going cars have single piston calipers, but there are quite a few more coming out with 2 pot and 4 pot calipers in recent years. It's great that the grip of tires, and increase in braking performance is actually starting to trickle down now
The reason they have more pistons is because cars are getting heavier, which means more force is required for wheel lock. Also 4 small pistons gives more even force than 1 large one, which is useful for very large diameter discs.
Can you make a video on the McLaren MP4-X concept car.
The addition of engine braking is a huge factor as well. Even more now with the Hybrid units...
As an American mechanic who specializes in brakes, I love this video. It shines light on things that I have dreamt of knowing and honestly, the facts are more insane than I expected. They heat the rotors for over a MONTH?! That is insane!!!!
Love the videos, and love you man. You have such a nice voice for narration and your knowledge base is wonderful. Can't wait for more content!
I love listening to your info about motor racing. Thank you!
Could you do a video on the body panels of race cars and how they get repaired or taken off during races?
Thank you very much for making these videos, they are very educational. I am totally surprised on the technology difference with the F1 and the street hot rod. Thanks again and have a nice day.
Those composite materials also the ceramics in sport cars have the amazing property of increasing grip and friction at high temperatures. As if the materials are designed for racing.
I was only ever a club, tin top racer, and the first time I used carbon metallic pads, on the Silverstone GP circuit, I flat spotted a tyre because they worked the other way around from the racing pads I was used to. Less pedal as the pads got up to temperature, not more! Lesson learned and a new tyre that only lasted one corner. Expensive when your sponsor is yourself. 🙄
New sub. Just found your channel, days of binge watching ahead and I can't wait always wanted to be a race engineer.
Another amazing video, thank you so much
Our pleasure!
Every time I watch your videos I am impressed and delighted. 8:52 1000 degrees for over a month? That's dedication.
This series of videos is so God damned good man. Thanks a ton for the amazing content.
Hi Scott. Great video! I've been wondering how racing drivers can modulate their brake pressure so accurately when pressing the pedal so hard! Clearly this is necessary to prevent lockups, for example
How you roll into ads or introductions is epic. Great video as usual
I remember braking hard on kart circuits through (bad) habit and one day in an endurance event I found myself pressing the pedal and no brake - it had overheated ! Terrifying experience as it was the first time it happened (like you often describe cars snapping away as you exceed the threshold range). I'd love to watch you chat to Jaaames but I've got stuff on ... Brilliant video - thank you :)
Before we "brake" down xD
Your videos made me realise just how expensive racing can be but I gotta admit that there is beauty in that insane engineering.
if you mean making a race car then yes!!!!!!!!! maybe thats why you see those drivers taking it very seriously
Subscribed. I find the engineering of these cars fascinating.
you can get these temps faster by having less surface area. the force per square inch would go up, resulting in more friction per square inch heating while also heating less material faster.
For all tuners watch precisely "They are not drilled"!(From brake pad side) = drilled doesnt mean better, it makes rotor weaker.
"over 6x" yet on screen it's 4x.
Also, the F1 car deccallerates wayyy faster then 2x as fast as a golf
Very intesting video that explains how race brakes works and what's the difference between the normal cars.. 👍
I guess that's why in games like F1 2020 for example the best way to brake is to start by 100% brake then gradually lifting whereas in a road car that would just end up locking the front tires, I assumed that was a result of the massive grip the downforce offered but I suppose the 'real life' answer is because the carbon carbon brakes were cold, curious now if the developers coded in that aspect of the brakes physics
Most of the F1 teams use a compound from Hitco, the same as used by most of the DPI teams. The Indy teams have tested those same compounds and are trying to change the rules to allow them ( they currently have to use the brakes from another manufacturer).
Great video, I love these technical ones.
Glad you like them!
That matierial was used also on the space shuttles nose and wing covers
Great content, thank you.
Great video, thank you for sharing🙌❤️🙌
Great video, slightly off topic question, what camera setup do you use? Quality looks amazing 🤩 🎥
We have a couple of GH5's, they are brilliant
On the straights, etc., they ride the brakes a little to warm them up before they do the hard braking into the turn.
What a Nice video! Tks for posting! I supposed that steel brake wheels were forged but with the vídeo I saw them being cast (less stiffness); I am a pilot and I fly one jet with carbon brakes. They work very consistent, I mean, braking efectiveness are supperb (dry runway, specially); - I had to refine my feet-feeling to get more confident with them! 🍾🇧🇷
I love this stuff. The tech was what drew me into F1. Incredible.
Interesting and usefully informative. Your clear explanations were not fogged by either high-falootin' bullshit or patronising simplicity. Well done!
Saw these being made, was amazing how long they took to make
How do they get brakes to bed-in? You know, how do they get enough material from the pads onto the rotors before a race to get the stopping power they need?
Your content is absolutely fantastic👍
That's incredible how fast these brakes can slow an F1 car down! 6 G's!!!
Another part that I'd be curious about is the history & function of the modern F1 car floor.
Wow, I just did the “improve your driving” questionnaire, it’s blooming accurate, describes my strengths and weakness’s to a T ..... blimey shocked how accurate it is
fun fact b7 rs4 used to have in 2006 360x34 8 piston steel brembos or as optional 380x38 6 piston carbon ceramics in front. the carbon disk, pads and wear indicators cost over 5500 euros and the disk is around 4500 euros itself. and this is only one corner :D
This is amazing technology. Thanks for going through F1 systems engineering. Help me understand how the car can brake at 6G but only have enough grip for 3.6G laterally? When I learned physics grip wasn’t different in different directions. Is this a tire(tyre) phenomenon?
tires work better longitudinally than laterally i guess, that's what they are designed for
Fun fact: The material used in F1 brakes (Carbon-Carbon) is the same thing that was on the Space Shuttle's nosecone.
The forge new limits sign is great, bit your head in front of it makes it read "forge limits"
I still don't understand why carbon brakes are so expensive, but I do want to buy some Forge Mits for some reason.
Oh man, you're on stereo too? That's awesome!!!
Another fabulous video, thank you
Great video! That was plenty of detail for people like me that know nothing about f1 brakes
Please demonstrate
How is lower and upper wishbone attached to uprights and chassis?
I have been thinking about what could be done with a cold gas thruster mounted on the unsprung part of the suspension. When needed, the thruster fires, applying several thousand extra pounds of contact pressure for each tire. Imagine how well a mini Cooper would stop on a slippery wet road if there was an extra 2000 lb of contact pressure on each tire... That might be enough to stop quicker than you could with the normal brakes on dry pavement. and yeah it'd be kind of a pain in the rear cuz he'd have to recharge the system and maybe replace some cosmetic panels that got blown off by the rocket thrust. But I think anybody who's been in a wreck would rather deal with that then deal with the usual result of having enough enough space to stop from 25 miles an hour (because of the wet) but you're going 45 mph.
Our company makes the breaks for the f1 cars McLaren and Ferrari buy from us it’s a mixtures lithium and aluminium really interesting to watch them do it
TOP NOTCH!!
Love the science involved.
👍🏁👍🏁
3:47 ‘breaks down the resin’ … there is no resin left in carbon/carbon pads & rotors. After the initial lay-up of the carbon fabric into the desired shape,the components are then roasted until all the resin is burnt away leaving just the carbon matrix behind. Then comes the expensive part … filling in the gaps with more carbon thru vapour deposition, which takes 3-6 months. Carbon, as an abundant element, is relatively cheap - it’s the time that adds the cost (and the cost of the energy to make it all happen)
my camaro has 1500 holes in the rotors. i got them from a friend that works at autozone. they smell like vanilla. also gave me stick-on vents for the calipers as well.
I found it interesting there is no steel in the pads. Makes sense though, at those temperatures.
We should not forget that F1 cars also use ERS which is an other name for regenerative braking. The F1 webpage states that ERS can provide 120KW of power in a lap. Most of that energy comes from the kinetic energy of the car during braking. So ERS helps considerably on braking.
Weel explained, clear and easy to understand even for those who aren't mechanics savy. Just one thing could you add english subs? For non anglophones people like me sometimes is hard to get all words correct.
So if both the pad and disk are made of the same material, do they not need to be bedded in before being used in a race?
FYI - Carbon Carbon tiles were used to keep the space shuttle safe from re-entry heating which reached several thousand degree Celsius
How long do carbon composite brakes discs take to cool down after red hot ?
Just subscribed. I’m very interested in learning about F1 technology
8:46 I would probably be cheaper build a massive solar furnace in the Arabian desert or Death Valley USA, and ship the discs to that place.
You will need solar power plant with energy storage capability to be able to maintain the furnaces working after sunset. Not that simple. But indeed in the long term that could make more economic sense. But I think we're getting rid of nuclear power too soon, though.
These types of videos are awesome!
I used to have a carbon clutch on my tarmac rally car, and it was by far the best "feeling" clutch i have ever driven on. But it needed to be hot to work. It would excessively slip until sufficiently warmed up. Once warm it was incredibly smooth, and easy to drive
Looking at the video showing the brake disk with all the friction being applied which almost causes it to almost go on fire because there is only one calliper would it not be better if it had two LARGER callipers with extra pistons which would apply more evenly proportioned grip for increased braking performance
something wrong with the youtube auto-generated subtitle, it show "Dutch(auto-generated)" instead of english
2:00 The brakes aren’t absorbing 6x the KE of a Golf, unless the Golf also has a similar aero package and KERS.
Thanks for the video series. Just a minor note @ 1:59 - I believe the math should read 1/2 * 746 * (100^2-13^2).
Justin you're correct, thanks for pointing it out. It still proves the point though, right. Thanks for your comment!
Once again Mr. 61 delivers a great video 🤙
6:33 road car brakes often have 2 pistons for the front wheels
Love the BTP video insert 👍
Is this a reupload, I remember watching this video a while back?
So brake rotors don’t warp it is almost impossible to get them too unless you put it in the same heat for the same time as when they are being cast what they do do is get so that the surface isn’t flat anymore and creates a spot that’s lower than the rest of the rotor
Great channel 👍🏼
Carbon-Carbon was used in some of the heat shield tiles of NASA's space shuttle. It probably is still used in some space craft heat shields
I really enjoy this content! Thanks so much for delivering high quality video as well as well as super fascinating content!!!
I have rewatched the moment at 5:22 about 10 times... It gets funnier every time.
It's sad the people get the wrong ideas of road card with Carbon Composite brakes, thinking they also need high temperature to work properly, they don't. They are adapted to road use and are brilliant. I even was warned at the Merc dealer against ordering with Carbon, and told how "they were only for track use and not good for daily driving", like they don't know anything or haven't tried them. Sure they need to be used once in a while, but that goes for all brakes. a normal steel disk not being used will also lose friction, until they are use a bit heavy and scrubbed off a layer of "polished" pads. My mom's car had useless brakes each time I lend it, for the first 5 minutes at least. (Porsche's 410mm PCCB is the best ever)
How do they maintain the heat in the rain?
i feel like they mainly cost that much because theyre not mass produced and they cant cover the design and manufacture cost by selling them in volume
When I start prepping my track car for hotlapping in the future, I'm looking at $900-$1,200 for racing brakes. I couldn't even imagine spending 50,000 pounds just for some brakes. 🤦🏾♂️
We got him to 500k, nicely done mate.
@Driver61 The math in this video make no sens at ALL! Title says it cost 50'000£, but the video text says 5000£ per disc. Also you say that they only last 250miles.
A normal F1 race is around 190 miles, so counting practice and qualy they drive more than 250 miles in a weekend.
Later you say it costs teams 500.000£ per year for disc/pads.
But if discs where 50.000£ each, that would only be 10 discs per year and thats asuming they get the pads for free... (since you provided no info of pad cost)
None of this math adds up what so ever!
Hmmm, your right. Seems odd! @driver61 can you explain?
These discs and pads are adjustable. The thickness of them starts around 35mm and between races they re-skim the surface and good as new.
