Raybestos disc brake caliper support keys maintain braking performance and reliability. Caliper support keys ensure even brake pad contact with the brake rotor to prevent unbalanced pad wear, noise, and vibration. Replacing worn support keys improves braking effectiveness to deliver safe and reliable driving performance. Raybestos parts are vehicle specific and they meet factory specifications so they are easy to install without any modifications. Raybestos provides a limited warranty for non-conforming products.
