Product details
The standard black left-rear CPB is a hydra-mechanical caliper with one 34 mm service piston and an integrated parking-cable actuator. Its floating body is intended to remain aligned over the rotor as the pads operate. The nominal 0.81-inch opening and 5.98-inch radial interface define this caliper version. 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
Match the rear bracket, rotor centerline and pad footprint to the exact mounting drawing. The rotor thickness must lie within 0.75–0.81 inch and its diameter within 11.00–13.00 inches. Check cable housing and end fit, lever movement and the M10 x 1.00 inlet, along with correct hydraulic balance for the complete brake package.
