Wilwood 5/8-inch GS Remote Master with Inverted-Flare Outlet and Threaded Inlet

This GS Compact Remote master uses a five-eighths-inch bore in a rebuildable die-cast aluminum housing. The remote supply connects through a threaded inlet, allowing the fluid container to be mounted away from the cylinder while the pressure outlet remains on the body. For motorsport, street-performance and specialized applications, Wilwood Engineering designs and manufactures disc brake systems and their components. The Camarillo, California company was founded by Bill Wood in 1977. Its range of rotors, calipers, valves, fittings, brake lines and master cylinders supports assemblies whose individual parts must be selected to work together.
