Product details

The red right-hand CPB provides two brake functions in one caliper: hydraulic stopping and a mechanical cable parking mechanism. Its dust-booted stainless piston is specified at 1.34 inches, equivalent to the nominal 34 mm designation. This version’s 0.32–0.38-inch rotor thickness envelope separates it from the wider CPB bodies. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications; selection depends on the complete brake system.

Fitment & Compatibility

The rear axle requires a bracket that establishes the correct radial height and rotor offset while allowing the caliper to float. Match the 5.98-inch centers and inspect the full wheel envelope. Check the vehicle’s parking cable end, actuation travel and hydraulic fitting independently; this caliper alone is not an axle conversion kit.
