As a hollow unit, is the expansion due to heat more linear? I can imagine that this is also because there is less material to absorb heat from the pad making it less of a heat sink. This is only a thought though.

Yeah that's it, I was dying to know, it was a track bike we (Me, Grunty and Squirrel) bought but life went wrong and everything had to be sold

so I never got a chance to work on it

i dont think brake pistons are cast i think they are drop forged then machined.

seems that everyone thinks it for weight and heat so far.

Any motorcycles use ceramic Pistons? The brakes on my mountain bike use ceramic Pistons which stops any corrosion issues.

the radial GSXR ones have a teflon coating

Ceramic would be too brittle for motorcycles

I was under the impression some Honda bikes had ceramic pistons. Could be wrong.

Maybe ceramic coated?

ceramics have come a long long way in recent years and they now make high speed bearings with it. the new bread of ceramics are tough as fek.

That is true.
I think it's years away before being viable for vehicles. Saying that if they start using them in WSB or BSB, it'll be 5 years from then before brembo produce a road suitable version
