Factory pre-assembled brake pad set for constant and exact braking. High-precision, ultra-efficient metal braking system pads are CNC-machined and accuracy ground on both edges for an ultra-smooth area complete to ensure maximum stopping effectiveness. Brake pad backing plates are heat-treated for maximum lifespan. Special high-grip braking system pad material is very fused to supporting dishes for high resistance to generated heat build-up.
