Product details
The black right-rear CPB combines a hydraulic service brake and cable-operated parking lock in one floating caliper. A 34 mm stainless piston acts within the dust-booted body. This is the standard nominal 0.81-inch rotor-width version, with a fixed radial bracket establishing its position over the rotor. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its disc brake systems and components serve motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among its products, selected according to the complete brake system’s requirements.
