Wilwood Rear Black Combination Parking Brake Kit for Ford Mustang (1994–2004), 12.88-Inch GT Slotted

Wilwood's rear Mustang CPB kit combines a hydraulic single-piston caliper with a cable-operated parking mechanism. Black calipers clamp 12.88-inch GT slotted rotors, mounted on hats for the 1994–2004 solid rear axle. The package does not fit Cobra independent rear suspension. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Confirm the 8.8-inch Ford housing arrangement and 3.25-inch axle offset before installation. For 1995–1998 cars, Wilwood specifically calls for a custom rear hose solution that it does not supply. Later hose references still require application selection. Check parking-cable attachment, rotor-to-caliper alignment and the wheel clearance drawing rather than assuming every Mustang rear brake package is interchangeable.

Match the individual model, year, submodel and brake configuration in the fitment table below.
