How to measure piston size:

e.g. 30x32 = 30mm in diameter; 32mm in height*



All seal and boot dimensions are determined by the piston diameter.

*Two common heights: 30 and 32mm


Why RB Stainless Steel Piston (vs. Aluminum):

1. Mush lower heat transmittal, only about 10% of aluminum = Less brake fluid replacement.

2. Better dimensional stability (Lower heat expansion rate) = Better rigidity in brake torque transmittal.



3. Detail machining & thin wall cut with chrome plate on surface.
