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! stereo.com/driver61 to join us!
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 ?
@@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.
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"!
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. 🎩👌
@@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.
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.
@@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
@@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.
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!
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.
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?
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. 🙄
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)
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!
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 :)
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
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.
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?
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.
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.
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.
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?
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
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.
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).
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
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)
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
At 2:00 the calculation for an F1 car is wrong, you’re supposed to take the square of velocity then subtract. You seem to be subtracting velocities before squaring, thus giving you a smaller number. It comes to 3,666 KJ
A road car has one piston calipers, then there is me: watching this in my 30 years old merc diesel with 4 piston calipers in front and two piston calipers in the back😅
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.
@Driver61 So road/track car brake pads release gasses when it's overheating due to material differences between the pad and the rotors. Does this mean slotted rotors actually help with removing these gasses? I had this debate with another track driver and he's adamant that slotted rotors are marketing fluff.
Plus they're there to aid in cooling the Rotor, obviously more so with "Cross Drilled" Rotors, but then the holes are are also diminishing the "surface area" available for optimal pad usage..... But they sure look cool.... Lol!!!!
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.
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
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.
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
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. 🤦🏾♂️
Great video but just asking is there then a very special biskpoke f1 brake fluid used as well that’s even more expensive than what’s used in GT 3 race cars let’s say
You said road cars only have one brake piston like that applied to all of them. I'm pretty sure there's some high-end performance cars that have multi-piston brakes and I'm sure you know that as well.
@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!
in 09 my 911 pccbs were 14k to replace…it wasnt a good feeling im sure with inflation today thats over 20k i got them bc i liked the yellow calipers on the gt silver..should of just powder coated them but youth and money isnt usually a great combo my current 911 has regular brakes
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
They may last for 250 miles - but a new disc is installed for EVERY race. And are made for each track specifically. Makes sense when every ounce of weight is a concern.

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.

That's incredible how fast these brakes can slow an F1 car down! 6 G's!!!
Fun fact: The material used in F1 brakes (Carbon-Carbon) is the same thing that was on the Space Shuttle's nosecone.

How you roll into ads or introductions is epic. Great video as usual

Tnx for the very unique and useful video that answered precisely what I was looking for.
I see, so we are talking about megawatts of energy dissipation in such small area/volume. Impressive. Even road car breaks are pretty impressive.

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.
On the straights, etc., they ride the brakes a little to warm them up before they do the hard braking into the turn.
Thanks
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.

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! That was plenty of detail for people like me that know nothing about f1 brakes
@3:06 how is "carbon carbon" a composite? wouldn't it mean they're just made of carbon? vs carbon ceramic for example?
Did some quick math:
2,983,818.5728 Joules of energy
Assuming
Mass=746kg
Velocity=200mph or 89.44 m/s
[Apply E=½mv²]
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
I love this stuff. The tech was what drew me into F1. Incredible.
I love listening to your info about motor racing. Thank you!

Another part that I'd be curious about is the history & function of the modern F1 car floor.

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
"we are breaking down every part of an F1 car".
In a while we'll see you building an F1 car just from these spare parts you use for the videos haha
6:33 road car brakes often have 2 pistons for the front wheels
Lol at 5:20 did you guys have to show that guys head slamming into the front like that?
"over 6x" yet on screen it's 4x.
Also, the F1 car deccallerates wayyy faster then 2x as fast as a golf
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.
I have rewatched the moment at 5:22 about 10 times... It gets funnier every time.
This series of videos is so God damned good man. Thanks a ton for the amazing content.
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
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?
0:20 I think you missed a zero
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. 🤦🏾♂️
Great video but just asking is there then a very special biskpoke f1 brake fluid used as well that’s even more expensive than what’s used in GT 3 race cars let’s say
How long do carbon composite brakes discs take to cool down after red hot ?
You said road cars only have one brake piston like that applied to all of them. I'm pretty sure there's some high-end performance cars that have multi-piston brakes and I'm sure you know that as well.
@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.
In 2:01 F1 cars absorb around 3.8 times the energy as a road car, not 6 times the energy as said spoken in the video.
Very intesting video that explains how race brakes works and what's the difference between the normal cars.. 👍
Why not watercooling them? Or LN2 cooling
Subscribed. I find the engineering of these cars fascinating.
in 09 my 911 pccbs were 14k to replace…it wasnt a good feeling im sure with inflation today thats over 20k i got them bc i liked the yellow calipers on the gt silver..should of just powder coated them but youth and money isnt usually a great combo my current 911 has regular brakes
I'm a mechanical engineer and this stuff is the reason why I want to specifically one day work as an automotive design engineer!
It’s all about weight.The cars race short distance with limited fuel.Heavy more durable disks add too much
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
They may last for 250 miles - but a new disc is installed for EVERY race. And are made for each track specifically. Makes sense when every ounce of weight is a concern.
