Product details

This right-hand Wilwood MC4 applies a separate parking brake through a mechanical cable rather than a hydraulic hose. Its anodized body, 1.19-inch aluminum piston and 4.75-inch mounting bracket suit the nominal 0.25-inch rotor-width configuration. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. It designs and manufactures disc braking systems for motorsport, street-performance and specialized applications, with a component range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility

Match the mounting plate and cable pull to the vehicle's parking-brake layout. Check actual rotor width and diameter, and ensure the cable end, travel and return arrangement suit the lever; this caliper does not replace the hydraulic service brake.
