Product details
This black right-hand MC4 is a cable-operated parking caliper for a nominal 0.81-inch-wide rotor. A die-cast body works with a forged anvil and steel mounting bracket, while a booted aluminum piston applies the parking pads. Pads, noise shields and the bracket are supplied with the caliper; its mechanical drive has no hydraulic inlet. 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
Check the 4.75-inch bracket interface and rotor centerline with the existing installation. This version lists a 0.70–0.81-inch rotor thickness range and 11.00–14.00-inch diameter envelope. Confirm right-hand cable approach, the 0.310-inch barrel end and enough lever travel, then adjust the parking mechanism using the appropriate MC4 instructions.
