Product details
Red powder coat finishes this left-hand Wilwood MC4 parking caliper. Its right-hand lever and offset plate with mounting holes on 2.00-inch centers distinguish the installation from MC4 units using a straight bracket or an opposite-pull actuator. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.
