Why RB Stainless Steel Piston?
Stainless Steel (vs. OE Aluminum) Piston :- Lower heat transmittal, only about 10% of aluminum
- Less brake fluid replacement & down time.
- Better dimensional stability (Lower heat expansion rate)
- More rigidity means more efficient in brake torque transmittal.
How RB pistons are made & advantage
- Machined from a solid 303 SS bar stock with high strength, hardness and rigidity compared to typical Aluminum pistons.
- Thin wall cut (vs. straight cut) to reduce the piston weight and increase of cooling surface.
- Vents (6x) assure stable contact with brake pad and quick brake release.
- Chrome plated mirror finish for an ultimate braking performance and extensive seal life.
- Eliminate multiple piece sub-components (seal inside the seal) like some OE (Porsche 996) pistons.
- Since our pistons are of ONE solid piece stainless steel so no "puck" to chip, separate, or melt (aluminum)

Advantage of a thin wall cut stainless steel piston vs. straight cut:
weight saving - Lighter wt means quicker brake response in braking and release.
