Product details

A chrome powder-coated compact master with a 1-1/8-inch bore supplies the tandem hydraulic circuits in this left-bracket kit. The combination valve and formed tubes accompany the master, while an operating pushrod is excluded. 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.
