Wilwood Compact Master Cylinder and Remote Reservoir Kit, 3/4-inch Bore, Black E-Coat

This three-quarter-inch Compact master kit combines a single hydraulic outlet with a choice of reservoir positions. Its black-coated aluminum cylinder has a 1.12-inch stroke and is supplied with seven- and ten-ounce containers for selecting the required fluid capacity. Since its founding by Bill Wood in 1977, Wilwood Engineering has designed and manufactured disc brake systems. Its Camarillo, California operation supplies master cylinders, brake lines, valves, rotors, fittings and calipers for specialized applications as well as motorsport and street-performance vehicles. Replacement and conversion parts need to match the complete braking arrangement.

Fitment & Compatibility

The pedal must accommodate the cylinder's full stroke and permit the pushrod to return completely. Verify the flange spacing, 5/16-24 rod connection and 1/8-27 NPT pressure outlet; the remote hose is a reservoir-feed line rather than a high-pressure brake hose.
