It's been a while. My car has been parked up in storage during a prolonged house move. Glad to say it's back home now, just!

The right hand front caliper had seized.

I managed to strip the caliper tonight. It seized due to being stuck fast against the seal. It was dry as a bone. No rust at all was inside.

I need to replace one of the 42mm pistons.

Can they be bought as original casting or have i got to replace both with something like the standard brembo 42mm piston?

Call PMB Performance to see if they have what you need.

+1, PMB all the way
