Product details
Wilwood supplies this right MC4 mechanical parking brake caliper with an anodized finish. Its 2.00-inch mounting span and 1.10-inch-wide rotor configuration are key checks when selecting a single caliper for an existing system. 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. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc braking equipment for motorsport, street-performance and specialized use. Calipers, rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must be matched to one another.

Fitment & Compatibility
Confirm the cable pull direction, the 2.00-inch offset mounting plate and the rotor centerline. Check that the cable has the required 0.310-inch barrel end and that the lever can return fully. This is one parking caliper; it does not replace the hydraulic service caliper.
