Red front hub brakes fit Bel Air, Biscayne, Impala and Caprice drum spindles. Check clearance around the 12.88-inch SRP rotors and calipers. The conversion combines the caliper, pad and rotor configuration specified for this axle and mounting arrangement. Wilwood Engineering was established in 1977 by Bill Wood and is based in Camarillo, California. Disc brake systems and components are its focus, from brake rotors and calipers to master cylinders, valves, brake lines and fittings. Its work spans motorsport, street-performance and specialized applications, with the complete brake system determining the correct individual components.
