Product details
The red right-hand Wilwood MC4 is a separate cable-operated parking caliper with a left-hand actuation lever. Its 1.19-inch aluminum piston has a dust boot and manual wear adjustment; the dedicated drawing specifies an offset plate with mounting holes on 2.00-inch centers. 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.
