ACDelco Advantage Coated Disc Brake Rotors deliver reliable stopping power with enhanced corrosion resistance. Each rotor is coated with a robotic-applied, baked-on layer to help prevent rust and seizing, even in harsh conditions. The non-directional ground finish extends pad life and minimizes thickness variation for smooth braking. Mill-balanced and built with multiple alloys, these rotors ensure consistent performance and durability — ready to install right out of the box with no machining required.
