Product details
A cable lever applies this black left-hand MC4 independently of the hydraulic service brake. Its die-cast body and forged anvil clamp a nominally 1.10-inch-wide rotor, with a manual wear adjuster and return spring governing the parking mechanism. Parking pads and a steel mounting plate with 4.75-inch centers are supplied with the individual caliper. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components, including calipers, rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized 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
Locate the mounting plate so the caliper runs over the intended parking-brake track; Wilwood lists 0.99–1.10-inch rotor width and 11.00–14.00-inch diameter for this version. Choose a separate cable with the specified 0.310-inch barrel end and check left-hand pull direction, available stroke and full lever return. The three-position lever cartridge helps route the cable, but does not replace checking clearance through the installation movement.
Parking pads and the mounting plate are included. Match the parking brake cable, rotor position, bracket placement and cable routing to the vehicle.
