Product details

A small integral reservoir and five-eighths-inch bore make this compact aluminum master suitable for the specified clutch and smaller hydraulic requirements. The bare body carries a screw-on cap, a threaded pedal rod and one pressure outlet. Based in Camarillo, California, Wilwood Engineering has designed and manufactured disc brake systems since Bill Wood founded the company in 1977. Its fittings, valves, calipers, brake lines, master cylinders and rotors are used across motorsport, street-performance and specialized applications. Matching a component means checking both its own specification and the braking assembly around it.
