Product details
The 2.00-inch floating attachment distinguishes this right Wilwood MC4 mechanical parking brake caliper. This individual black unit is built for the 1.10-inch-wide rotor configuration and requires accurate alignment with the mating rotor and bracket. 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. For motorsport, street-performance and specialized braking applications, Wilwood Engineering designs and manufactures disc brake systems and their individual components. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood supplies a range encompassing calipers, rotors, master cylinders, valves, fittings and brake lines, all selected to match the complete system.

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.
