Product details

This adapter joins the specified Wilwood billet reservoir to a compatible remote master-cylinder inlet. The two different connection sizes—9/16-18 and 11/16-20—must be matched to the components on either side of the fitting. A complete brake system depends on compatible component selection. Wilwood Engineering designs and manufactures disc brake systems along with calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized use. Bill Wood founded Wilwood in 1977; the company is based in Camarillo, California.
