Pistons (Stainless Steel)

How to determine piston style and size:


All seal and boot dimensions are determined by the piston diameter, but must note whether you have external or internal fit boots.

Why RB Stainless Steel Piston (vs. Aluminum):

1. Much lower in 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.
