I'm not positive what you are referring to. Carbon is a common material found in friction material, but by volume it is a small amount added as a friction modifier and a thermal conductor.

If you are speaking of carbon fiber rotors, it is just the rotor that has carbon fiber and I don't really know what other materials are added to the carbon fiber, but I know lots of people that do know. I'll ask next time I have some BS time with one of them.

I was under the impression that the brakes used on high end race cars like Formula 1 were carbon fiber until I watched the Canadian GP this past weekend. During the broadcast I thought either Matchett or Hobbs say they weren't using carbon fiber anymore but carbon carbon. They also said they were carbon cinders. I think that's what I heard. 

Anyway, it was a carbon reinforced carbon panel that failed due to impact that caused the Space Shuttle Columbia disaster. It failed because while the material is strong and has great heat related properties it is brittle. I didn't think brittle would make good brakes so I was wondering what the F1 brakes were made of these days. I guess they could have been referring to carbon reinforced silicon carbide, but that didn't sound like what they talking about on the F1 broadcast.  They made it sound like they were using a purer form of carbon.

Ford doesn't put Brimbo on their vehicles, not even their Shelbies as far I I know since we produce them all. They must be after market sales by people that have more money than brains.

Thanks brakeman for the insight.

Brembo's are offered as an factory option in the $2500 "GT Performance Package" - Brembo calipers and larger rotors is the pitch, FWIW. That $2500 includes a number of other items as well, including a limited-slip diff, larger wheels and so on.

I have a lot of experience in Sensors and their manufacture as well.

When will we have "wet" disk brakes on cars?

Fluid cooled brakes, usually oil, are heavy, require a complete cooling system, and are very fuel inefficient due to the constant and considerable fluid drag on the stationary vanes. They are more suited to dirty environments because they are self-contained. I don't think they could handle the high thermal conversion of a high speed stop, the designs I read on the web would explode under a racing stop. Our Japan heavy industries division probably has some fluid cooled brake designs, but I've never pulled up the prints as I'd just be fishing to find it on our system since there is no "search key" term to find fluid cooled brakes."
