Product details

This anodized left-hand Wilwood MC4 uses the right-hand cable lever specified for this configuration. Its offset mounting plate and mechanically applied piston provide a separate parking brake, with the nominal 0.81-inch rotor width selected independently of the hydraulic service caliper. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components. Bill Wood founded the company in 1977; its motorsport, street-performance and specialized range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines.
