Product details
This red Wilwood MC4 right mechanical parking brake caliper uses a 2.00-inch floating mount and the 1.10-inch rotor-width configuration. It is sold as one caliper, with its piston and mounting specification selected for the complete brake assembly. 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. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures calipers, rotors, master cylinders, valves, fittings and brake lines as part of its disc brake range. Its motorsport, street-performance and specialized products are chosen around the requirements of the whole braking system.

Fitment & Compatibility
