Product details

The drilled rotor option uses black Superlite calipers over 14-inch iron friction rings and the Bronco-specific parking hats. Its rear housing-end interface is the New Style 2.36-inch-offset arrangement, with internal parking shoes supplied alongside the service-brake components. Wilwood Engineering designs and manufactures disc brake systems and components in a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977, and it is based in Camarillo, California. The range serves motorsport, street-performance and specialized applications, with component choice governed by the complete system's requirements.
