Are TWB's brains available for picking? or just pickling? Mon Jul 30, 2018 5:50 pm

Yes, I know you're on tour and yes, I know my sense of timing is absolutely lousy 
and no, I don't expect an answer (if any) before you get back to the grindstone 
.
I just pulled apart a pair of four-pot opposed-piston Brembo calipers (provenance unknown) that used to adorn the front of my Moto Guzzi V1000G5. All four piston sizes are 20mm x 32mm diameter; exactly the size of the smaller piston in the four-pot K100RS etc. brakes. A chat to my not-so-local Guzzi parts supplier revealed that Brembo no longer list an overhaul kit for these calipers. I'm a bit reluctant to shell out for eight K100RS overhaul kits (I wonder why?) when all I need is three pistons and eight sets of seals.
So, the question is (when you are in a position to be able to answer it), have you any idea which other BMWs use the same size caliper pistons?
