Why rebuild OE calipers with RB components (piston):

Left OE / Right RB (OE 31.8x30.1mm vs. RB 32x30mm) Made with same material of Stainless Steel.

  • RB Piston are vented for quick piston engagement and release.
  • RB pistons are mirror finished and chrome plated to assure the smooth movement and lasting durability.
  • RB pistons feature thin wall cut - Very light weight (2/3 of OE) for a more efficient caliper operation.
