Could someone tell me a little bit about them all I know is that the hoter they are the better the better they work thats it.
Thanks

they reduce unsprung weight by i think upwards of 40% and also they reduce brake fade tremendously, the down side is they will cost you more than most toyotas to equip to your porsche

yes like porsche said they are alot better than the other materials used in brakes. But they can shoot up in prices, are you looking at putting them on your car, or are you just wondering about them?

"The best way to predict the future is to invent it."
carbon ceramic (silicon carbide matrix) have a very high specific heat capacity which allows them to absorb more heat in less time so to speak, this allows the brakes to turn more kenetic energy to heat (slow the car down), most race car brakes are actually carbon carbon brakes (carbon fibre in a carbon matrix, yeah its confusing, i dont get it myself) with a carbon ceramic coating since carbon carbon brakes dont work well with moisture (even the moisture in the air will severly hinder their performance) and will burn in air once they reach 500 degrees centigrade
steel and aluminum brakes arnt really used in racing since they dont have the specific heat capacity of carbon carbon or carbon ceramic rotors, these brakes can reach 1600 degrees centigrade under full braking power while normal rotors will melt at those temperatures, yes i said melt
do you want to put it on a car?for racing?Originally Posted by lukehow

carbon brakes dont solve the problem of fluid overheating (as far as i know)
steel rotors are still by far the most widely used brakes (+95%?). only the top formulas (F1, F3000, etc.) use C-C and only a few others outside of these classes (some lemans prototypes and GT, MotoGP, ...)
not to forget porsche, as i mentionedOriginally Posted by johnnyperl

porsche race cars (911 cup etc.) do not have carbon brakes.Originally Posted by my porsche
there are probably more (by individual car) street cars (360CS, porsches, enzo, MC12) with carbon brakes than race cars
carbon brakes need a lot of cooloing. porsche has had problems with it's PCCB (Porsche Carbon Ceramic Brakes) overheating due to poor cooling in Turbos and GT2s due to inadequate cooling due to the design of the front bumpers. however they still work awesome and will last 400,000+kms

Wasn't there a problem with some PCCBs degrading after only a few thousand miles?Originally Posted by 2ndclasscitizen
As I understand it they tend to work best with a bit of temperature in them, rendering them largely pointless on road cars which spend a lot of time at low speed in town, or cruising at constant speeds on the highway/freeway/motorway/autostrada/route national/autobahn/whatever.
Thanks for all the fish
do they dissipate heat well, or does it stick around for a while?Originally Posted by Coventrysucks
but yeah, it would be basically useless to have them on a road car

im gonna put carbon brakes on my sentra
