This straight Wilwood adapter screws into the specified iron GM Metric caliper and presents a male -3 hose connection. The included crush washer seals the caliper-side interface. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and builds disc brake systems for motorsport, street-performance and specialized uses, including calipers, rotors, master cylinders, valves, fittings and brake lines. Each part must match the requirements of the whole braking arrangement.
