One of the benefits of ceramic bearings (besides lower rolling friction) is cool running. Maybe running cool helps keep friction down?

Ceramic brake pistons probably don't transfer much heat to the brake fluid, which is a good thing.

Good suitable road going brakes are here now. If you need racing brakes on your street bike, you should take it to the track. Actually modern sport bikes have racing brakes from the factory.
If ceramic pistons were cheaper, we'd likely have them now on everything. If they work better, then WSB and GP bikes already have them.

Hard braking at every corner, especially from high speeds, will sometimes overheat common brake fluids, but you can use uncommon fluids if you're racing, and if your street riding includes hard braking from high speeds at every corner... wouldn't you be racing on street circuits?

And maybe dissipate heat quicker than metal pistons?

Probably lighter too?

I think they might use impact extrusion to make the rough shape and then turn them on a lathe to get the dimensions more accurate. It'd save tooling costs over turning them from a solid piece.

They're probably hollow to save money on material as well as reduce expansion effects

Bikerstoolbox.co.uk sell different tools to suit your budget, I just got the mole grip type tool since the cheaper ones were rubbish.
