Wilwood 1-1/8-inch Combination Remote Master Cylinder Internal Rebuild Kit

A one-and-one-eighth-inch piston distinguishes this larger-bore Combination Remote rebuild kit. It renews the hydraulic sealing assembly and associated spring, boot and retaining parts without supplying a cylinder body or reservoir. Wilwood Engineering's design and manufacturing work covers disc brake systems for specialized applications, street performance and motorsport. Founded by Bill Wood in 1977, the company operates from Camarillo, California. Its component range includes master cylinders, fittings, brake lines, rotors, valves and calipers, each requiring selection in the context of the complete brake system.
