Wilwood Left-Bracket Chrome Remote Master Cylinder and Valve Kit, 7/8-inch Bore with Pushrod

A chrome powder-coated Remote Tandem master gives this 7/8-inch kit a separate-reservoir layout. It arrives with the captured pushrod, two 7 oz containers and the left-hand valve assembly, including formed master-to-valve tubes. 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.
