Product details
A red powder-coated CPB housing provides the service and parking functions in one left-hand rear caliper. Hydraulic pressure applies the 41mm piston, while the separate mechanical actuator locks the brake through a suitable parking cable. Bill Wood founded Wilwood Engineering in 1977, and the company is based in Camarillo, California. It designs and manufactures disc brake systems and a component range of calipers, brake rotors, master cylinders, valves, fittings and brake lines serving motorsport, street-performance and specialized installations.
