Product details
Wilwood MC4 calipers must be matched by width and mounting configuration. This black left mechanical parking brake caliper has 1.19-inch bore dimensions, a 2.00-inch mounting span and the 1.10-inch-wide rotor specification. MC4 is a separate cable-operated parking caliper with a manual wear adjuster and return spring. Its lever accepts a 0.310-inch barrel-ended cable and can be clocked for routing. Pads and the caliper mounting plate are supplied; parking cables and a vehicle-specific conversion are separate. The Wilwood disc brake range is designed and manufactured for motorsport, street-performance and specialized applications. It includes brake lines, fittings, valves and master cylinders together with calipers and brake rotors. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California; its components must be matched to the complete braking system.

Fitment & Compatibility
