Product details

This black 15/16-inch compact tandem kit includes the pushrod and a left-mounted combination valve. Preformed tubes connect the master cylinder and valve while keeping the front and rear hydraulic circuits separate. Since its founding by Bill Wood in 1977, Wilwood Engineering has designed and manufactured disc brake systems. Its Camarillo, California operation supplies master cylinders, brake lines, valves, rotors, fittings and calipers for specialized applications as well as motorsport and street-performance vehicles. Replacement and conversion parts need to match the complete braking arrangement.
