Product details
Black powder coating finishes the left-hand thin-rotor CPB caliper. The hydraulic piston applies the service brake, while a separate cable input operates the parking lock in the same floating assembly. This combination is intended for suitable rear disc conversions or replacement of an identical CPB configuration, with a 0.38-inch nominal rotor width. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. The manufacturer produces disc brake systems and components for motorsport, street-performance and specialized applications, with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Individual components are chosen to suit the complete brake system.

Fitment & Compatibility
Compare the complete rear brake arrangement with the caliper drawing, not just the nominal piston diameter. The rotor must meet the 0.32–0.38-inch thickness limits and be centered correctly in the sliding body. Check cable approach, lever clearance, bleeder position and the receiving radial bracket before selecting this left-hand unit.
