Product details

The left-mounted combination valve joins a chrome powder-coated, one-inch compact tandem master in this package. Its input does not include a pushrod, so the actuator must be selected around the compatible booster or linkage arrangement. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, Wilwood designs and manufactures disc brake systems and a component range covering master cylinders, rotors, calipers, fittings, valves and brake lines. Across its motorsport, specialized and street-performance applications, the correct choice depends on the complete brake system rather than one dimension alone.
