Product details

This black right-hand Combination Parking Brake caliper combines a hydraulic service brake with a cable-operated parking lock. It is the thin-rotor CPB configuration for a nominal 0.38-inch width, rather than an electric parking caliper. A single 34 mm piston works in a floating body carried by a fixed radial bracket. 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.

Fitment & Compatibility

Choose it for a rear conversion or matching replacement only after checking the rotor and axle bracket. The published rotor diameter range is 11.00–13.00 inches, and the fixed bracket uses 5.98-inch radial centers. Verify cable travel and end fittings, the M10 x 1.00 hydraulic connection and correct bias with the front brake package.
