Product details
This red Wilwood MC4 is a right-hand cable-operated parking brake caliper for nominally 0.81-inch-wide rotors. The included steel mounting plate uses 2.00-inch mounting centers. It provides a separate mechanical parking brake rather than hydraulic service braking. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and parts for motorsport, street-performance and specialized applications, from calipers and rotors to master cylinders, valves, fittings and brake lines.

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.
