Factory pre-assembled brake pad set for constant and precise braking. High-precision, ultra-efficient steel braking system pads are CNC-machined and accuracy ground on both sides for an ultra-smooth area finish to guarantee maximum braking efficiency. Brake pad backing plates are heat-treated for optimum lifespan. Special high-grip brake pad material is particularly fused to supporting plates for high resistance to generated heat build-up.
