Wilwood 1-1/8-inch Compact Master Cylinder Kit with Black Body and Remote-Mount Hardware

This 1-1/8-inch version provides the largest bore in the specified Compact Remote family while keeping the same flange footprint. Its single pressure circuit can be supplied by either included plastic reservoir, mounted on the body or located remotely with the supplied hose and bracket. Bill Wood's founding of Wilwood Engineering in 1977 established a disc brake design and manufacturing business based in Camarillo, California. Calipers, rotors, master cylinders, fittings, valves and brake lines form its range for motorsport, street-performance and specialized applications. Choosing a service component still requires checking the mating parts and overall system configuration.
