Brake Pads; Noise-cancelling 5-Layer shims minimize vibrations and optimize noise-cancelling performance Application-specific friction compounds restore Import OE performance; European applications feature ECE R90 certified friction formulations Break-in Coating promotes a quicker, more effective break-in of the pad and rotor and reduces future onset of brake pedal pulsation OE-style Chamfers and Slots help dissipate heat throughout the brake pad and minimize noise PTFE And Rubber Coated Hardware (where available) reduces friction to prevent pad-to-hardware binding Low-dust friction formulations help keep your wheels clean
