Product details

A four-bolt mounting flange is built into the black 15/16-inch compact master in this manual-brake kit. The supplied pushrod and left-side combination valve must match the pedal and hydraulic circuit arrangement. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. Its disc brake design and manufacturing range includes valves, master cylinders, calipers, brake lines, rotors and fittings for street-performance, specialized and motorsport use. These parts are selected together so the completed braking system has the required hydraulic and mechanical arrangement.
