CALIPER REBUILD

How to determine the piston size (mm):

e.g. 30x32 = 30 in diameter, 32 in height



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

Why RB Stainless Steel Piston (vs. Aluminum):

1. Lower heat transmittal, only about 10% of aluminum
2. Less brake fluid replacement & down time.
3. Better dimensional stability (Lower heat expansion rate)
4. Better rigidity in brake torque transmittal.

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