Product details
For a dedicated mechanical parking brake, this right-hand Wilwood MC4 uses a cable lever and red floating body. Match its 4.75-inch mounting plate and 1.10-inch-wide rotor-width version to the brake assembly. Wilwood Engineering’s disc brake range includes calipers, rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977 in California; it is based in Camarillo and serves motorsport, street-performance and specialized brake applications.
The MC4 is a separate cable-operated parking brake caliper, not a hydraulic service caliper. Its lever can be clocked in three positions for cable routing, with a return spring and a manual wear adjuster. The lever accepts a 0.310-inch barrel-ended cable.

Fitment & Compatibility
Use a separate parking brake cable with the correct barrel end and sufficient lever travel. Check cable pull direction, lever clearance and mounting-plate position. This mechanical caliper does not connect to a hydraulic brake hose.
Parking pads and the mounting plate are included. Match the parking brake cable, rotor position, bracket placement and cable routing to the vehicle.
PMB Performance has worked with parts and brake fitment for over 20 years. Supply the installed caliper identity and the rotor and bracket measurements for a practical compatibility check.
