Product details

This chrome powder-coated remote-master kit retains separate fluid feeds for the tandem circuits and includes the classic Mustang pushrod arrangement. Its 15/16-inch bore and left-mounted valve must suit the existing brake installation. Wilwood Engineering designs disc brake systems and manufactures a range of calipers, master cylinders, valves, fittings, rotors and brake lines. Founded in 1977 by Bill Wood, the Camarillo, California company serves specialized, street-performance and motorsport applications. Component selection requires understanding the brake assembly as a whole, including its hydraulic sizing and mechanical interfaces.
