    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! stereo.com/driver61 to join us!

      1. Observing Rogue

        This makes me think about an AWD electric vehicle, Regen Braking all wheels. Even in a race setting, would Regen allow the use of normal brake rotors & pads?

      2. isaacroc

        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 ?

      3. A-6M ZERO

        PLEASE NO MORE MUSIC .

      4. Pablo Rodríguez Roca

        what it's incredible is people using stupid measurement units like miles

      5. N Woida

        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?

    2. Who is John Galt?

      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.

    3. Chris Braid

      So what about the regen braking ? Would it help to have supercapacitor battery banks to absorb the energy and fire the car out of the corner you just braked into ?P.S. I don’t like the way that brakes waste energy and slow us down. We need to relearn driving with minimal braking as it gives our vehicles better balance ....

    4. William Su

      What is carbon carbon? Are they just a pure carbon material, or are we talking about like a refractory ceramic carbide?

    5. Pwnzistor

      Fun fact: The material used in F1 brakes (Carbon-Carbon) is the same thing that was on the Space Shuttle's nosecone.

    6. Shadowboost

      I've been to the shop that machines those holes. Very cool shop, made some really amazing shit, including some of my parts

    7. Alex Manning

      I really enjoy this content! Thanks so much for delivering high quality video as well as well as super fascinating content!!!

    8. Junior Johnson

      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).

    9. AHands

      Wait - You show in your video they are £5,000 ($6,900) per corner. Honest mistake or deliberate clickbait in adding another zero?

    10. n 135246

      instant 2' : less than 4 times the energy, not more than 6 times, according to your calculations

    11. James Drissel

      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.

    12. Panagiotis Demelis

      What Great videos you Guys do! Keep up with this Great work. What is also good about your videos, to my opinion is that one can see, that the impression that F1 technology is gradually transferred to every day Cars is quite misleading and many times irrelevant.

    13. Milos Balunovic

      mentioning more braking force, and number of "pistons" .... you are aware that only hydraulic pressure area is what is important (and on one side also regarding the "clamping force" )

    14. Fuel

      Awesome content! Really inspired by Driver61 a lot. Starting up our very own youtube channel about automotive and anything regarding cars/wheels! Can show some love towards our channel? Give some comments for us to improve! :D

    15. Peter Mainwaring

      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. 🙄

    16. Kitty

      0:19 are they 50k or 5k? make up your mind

    17. Markus Patients

      If I were a racecar driver I would never use the breaks. Better yet, have them taken off to save weight...

    18. Laugh Sandwich

      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

    19. busybee

      only reason...theyv e.... F1 in the name any joker can get the same for half that price

    20. Chris H.

      Why they don't use magnetic brakes without friction??

    21. OddJobMTB

      They cost 50k to buy or make? Big difference.

    22. Nicholas Cartlidge

      Love the channel. Why aren't f1 wheels made of carbon fibre?

    23. Juttla Family

      How do 1 make carbon -carbon.

    24. Haden Vardaro

      Could you do a video on the body panels of race cars and how they get repaired or taken off during races?

    25. usernamwdrama

      Awesome stuff.

    26. Meton12765

      Also, that using your own body-weight and momentum to aid in braking. That's a thing for Saab-drivers. Whether you want to or not. You definitively need to replace seatbelt pre-tensioners every 5 years or so. as they do get activated quite a bit. :D :D :D But, then again, plebians gonna pleb.

    27. Meton12765

      Yeah, and yet again, wrong. Road cars with high performance braking systems. also use grooved / drilled vented discs to allow somewhere for the gas to flow and not to create a gas layer between the pad and the disc. This is effin' brake engineering 101 from the 1980's for heavens sake. Road cars _have_ come along quite a bit in the past 30 years. Mostly thanks to F1 and Group B and later WRC pushing the damn envelope. :D The advances in motor racing most often, translates to actual real-world advances in road cars. THAT'S WHY THE CAR COMPANIES DO IT IN THE FIRST PLACE! Such as, the Carbon Ceramic Composites they use to coat Porsche discs with. The material is nano engineered carbon lattice over a vented disc. And it doesn't wear more than 0.1mm over it's entire use life of around 50 000km. Same tech is being applied to F1 and airplane brakes, as this approach mitigates the cooking off of brake fluid and dissipation of break pad material phenomena as they are effective at far lower operating temperatures and don't, you know, plume off like a old school carbotanium cooked in a steel kiln for a moth. :D

    28. Meton12765

      Yeah, no. Shitty road cars only have one piston. :D Saab (in it's 20 year old, Old Gen 900 form) had twin piston vented discs with ABS. In 1991. And in the OG9-3 and NG900 they have four at the front in Aero and High pressure turbo spec. Esp the Viggen has this taken to full-tilt stop-on-a-dime from 250km/h. :D And maintained this level of stopping power up until the demise of the marque. Volvo wouldn't settle for anything less, and I do believe they're S90 T8-R has quad-piston vented in the front. And twin piston vented at the rear... Something I often need to remind myself of when driving. Since, cars around me, DO NOT stop in less than 50m from 80km/h roadway speeds if I really stomp on them, in good summer weather, naturally. And I don't drive with anything but fresh rubber, that is, 2 year old tires ain't good enough anymore. :D Also, the process used to make those carbon brakes, isn't just "very similar" to airplane carbon brakes. It's literally the _same_ process. In fact, that brake caliper you handled at one point of the video that you allude to being F1 part. Well, it also has aeronautical part classification. Because, standardization, motherfuckers for the win! :P

    29. Wind of change

      Easy, I can tell you this without watching the video. Simple design, high tech and expensive carbon ceramics.

    30. magpierh

      The numbers in the voiceover don't tally with the figures on-screen; you say 750MJ while the image shows 734, then say the F1 car experiences over 6x the force, while the image says 384% (so almost 4x)

    31. Bigbot Hoee

      Doesn't cost 50k if your paying that you getting rapppped

    32. dubtube

      Whatever it is it has to be expensive because it's F1, it's part of the show

    33. Carl Harverson

      Ah carbon, that rarest of rare elements

    34. CRISPY DUCK

      I thought the thumbnail was a watch

    35. minty

      Weird how it's the opposite in cycling. Carbon brake tracks are worse of a braking surface because they're way worse at dissipating heat than aluminium

    36. nasos nasos

      Love

    37. Whisky Canuck

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

    38. elvewizzy

      Ferrari engineers: Write that down! Write that down!

    39. Pip Pipster

      0:20 But I thought you said £50,000 ... Here it says £5000?

    40. Ryan O'Keefe

      I have rewatched the moment at 5:22 about 10 times... It gets funnier every time.

    41. Tri Handoko

      Do yo know what? The airplane brake is more advance and more expensive than this

    42. Audiojack

      "This caliper has six pistons where a road car system only has one." Most certainly still do, but if your vehicle is heavy-duty or performance oriented, it's not uncommon to see 2-pot or 4-pot calipers, and some do sport 6-pots and even 8-pots too, on some relatively tame supercars like the Audi R8.

    43. rkan2

      5:50 - -20c only? :D I think most car brakes will work way past the point of your engine oils or fuel..

    44. Observing Rogue

      ...So F1 disks, are like expensive alcohol or cheese, or meat? The cost is from the extra time, care, and quality-over-quantity business model.

    45. David Baker

      Can u (or anyone else!) explain how the hell a front wing can possibly cost over £200k? (According to Christian Horner!)

    46. ngc 5139

      Stop exaggerating.

    47. aleksandar tokin

      Fun fact, pure carbon has a higher melting point than tungsten carbide

    48. Crooks

      Science

    49. Robert

      Try converting the brake energy into the horsepower equivilant if you really want to blow some minds.

    50. Mean Cat

      I wish one day he gets to assemble a F1

    51. Giles Bonner

      @3:06 how is "carbon carbon" a composite? wouldn't it mean they're just made of carbon? vs carbon ceramic for example?

    52. Claude Baron

      Just for any rides out there that are streets legal, theirs tones of products available form cheap to very expensive, just for my sport bike it’s street legal and already most sport bikes are already very well equipped of everything but if I want to change the calipers ‘’ just the calipers, no pads, no hoses, no master cylinder, for 2 calipers of the brand Brembo ( witch are in the best ones if not the best ) no the top quality but a very good one the prices for 2 calipers Brembo are around $ 2,000 , so imagine for a F1 😂😂😂😂😂 But ever heard the expression ‘’ to stop on a dime ‘’ !? With this it’s almost true, I’ve tried one bike on time who was all set-up for racing , not as a factory one but still, and I’m used to rides motorcycles, 35 years experience, did racing, stunts, you’ll name it !, and the first time I used the front brakes on this bike,( and I was been carful ) I almost fly over the handlebars, as it stopped so brutally guess it takes times to use to.

    53. Mansour

      These brakes are ancient lol

    54. SS454LS6

      I was able to hold an F1 brake disc at the 2012 Canadian GP and I was blown away at how light it was.

    55. Vincent Menke

      That matierial was used also on the space shuttles nose and wing covers

    56. Crispy K

      Still doesn't explain the 50000£ price... I doubt that there's more than 15000£ worth of materials. But people will pay 50000£ and the "manufacturers" use "research" as an excuse for the high price. But you don't redo the research when you produce a disc. You just make a lot of discs based on the research that's you've already found, and most likely already made the money back so now it's just profit. But i might be wrong ;)

    57. Roosevelt Brentwood

      oh oh I know this one! it’s because f1 cars go really fast and have to stop quickly!

    58. arekdbz3

      It is good that you highlight "world fastest GAMER". Let it be clear. Cause there are dozens of better simracers in iRacing if not in hundreds

    59. Hubert Behrendt

      Cast iron* not steel

    60. Jeff Vlimant

      I remember an episode of Top Gear where Jeremy Clarckson tried an F1 car. What you tell in his video is pretty much the explication of what happened for him and why he was so inconfortable in it. Your videos are SO good man !!

    61. That Guy

      Subscribed. I find the engineering of these cars fascinating.

    62. Rafael Teixeira

      F1 numbers always surprises us

    63. Data Recovery Sweden

      Great content, thank you.

    64. Bartłomiej

      02:02 380% read as "over 6 time energy"...

    65. The Real Alfalfa Male

      How can a disk be over £50K per corner when a disk is round?

    66. Tony Perri

      carbon-carbon is what the thermal tiles on the space shuttle were made of

    67. Benjamin Whedon

      This series of videos is so God damned good man. Thanks a ton for the amazing content.

    68. Niko942

      Unfortunately stereo.com doesn't support PC's at all, only phones. They don't even allow us to download the past podcasts. Is there any chance the podcasts could be uploaded somewhere where PC users could get access to them?

    69. Anonymous Person

      Think of thousands of these piling up in landfill.

    70. zOlid

      @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!

      1. David G

        Hmmm, your right. Seems odd! @driver61 can you explain?

    71. Yash P

      Probably I need this one for my cycle

    72. Mario Blanco Gonzalez

      2:00 the maths for the kinetic energy of the F1 are incorrect. Actually, the kinetic energy difference is 1/2*[mass]*[[Initial speed]**2 - [final speed]**2], instead of what's shown in the video 1/2*[mass]*[[Initial speed]-[final speed]]**2. But the overall message is well understood

    73. Digital_Jedi

      6g of stopping force. That's 6g in the forward direction. A human head weighs about 11lbs or 5kg. The driver's head is being pushed forward with 66lbs or 30kg of force. They could likely lift a small child with their neck muscles.

    74. SubZero

      Would carbon carbon breaks get up to temperature in hotter climates? I've experienced breaking fading too many times to not consider this as an option or at least something similar

    75. Gseric47

      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. 🤦🏾‍♂️

    76. Brap Brap

      5:42 is that a pad from an MX5 on the right?

    77. Nisten T

      Hey can you make a video about the air system of the pilot in racing cars. I I know fighter pilots have to store their liquid oxygen, is it the same for F1 drivers? How is it protected? Can the can explode? When in history was this first introduce? Do they breathe pure oxygen or a mix or nitrogen? I have no idea if there's enough to this for a whole episode but rather than going in a rabithole of research myself I much preffer the way you compress technical knowledge in these videos :) Cheers

    78. EqualsThreeable

      Is this a reupload, I remember watching this video a while back?

    79. Luca Gattoni-Celli

      Another fabulous video, thank you

    80. Cktime ThirtyTwo

      “Why they would be useless if you applied them to a road car” As thousands of Mercedes, McClarin, Lamborghini and Ferrari owners run around the town on ceramic brake packages 😂

      1. Steven Kelby

        That's a spurious argument.

      2. Driver61

        Carbon Carbon and Carbon Ceramic are pretty different

    81. Big J small j

      Good insight thank you. It all comes down to economies of scale really, doesn't it. If they were to be made in millions then the production would be cheaper, not as cheap as the steel discs but a lot cheaper than what they are. But of course since there is no such demand they will never be made in millions, hence always 100 X expensive

    82. CED99

      2:00 2832/734 =/= 7x Also kJ as BTP point out not MJ - so out by a factor of 1000 there 0.5*746kg*(87m/s)^2 = 2823237 J 50,000/50 = 1000 not 100 as well Enjoyable video though :thumbsup:

    83. Harry Nelson

      These are not bad, got some on my ford KA

    84. James Sharpe

      The forge new limits sign is great, bit your head in front of it makes it read "forge limits"

      1. Steven Kelby

        I still don't understand why carbon brakes are so expensive, but I do want to buy some Forge Mits for some reason.

    89. alberto robinson

      Cheers

    90. Stefan Liesker

      Don't think they use woven carbon fibre. Believe they are single fibres.. minutely small.. and pressed into a mould and backed. No resin in the brakes

    91. Connor Seaborn

      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?

    92. Taylor Turk

      Very informative video, I greatly enjoyed it. I’ll never download stereo! Don’t need more video apps that do what a podcast already does

    93. Capewell Productions

      Oh man, you're on stereo too? That's awesome!!!

    94. Badeend

      use a tree, its way cheeper dont tho

    95. abhigejf

      Cutting edge tech, never heard of an iron ;-p

    96. Beyond the press

      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.

      1. SubZero

        So awesome to see you here!
