Product details
A black left-hand MC4 caliper provides cable-actuated parking hold in this 0.81-inch nominal-width format. The sliding design incorporates an aluminum piston protected by a dust boot and a manually adjustable lever mechanism. It is supplied with the steel bracket, parking pads and noise shields described for this exact mechanical caliper. 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
Confirm the left-hand cable pull and the 4.75-inch bracket pattern. A rotor within the 11.00–14.00-inch diameter envelope must also meet the thickness range and align with the pad faces. Check the barrel-ended cable connection, full return movement and available wheel clearance, then set the mechanical adjuster for the completed installation.
