Wilwood 13/16-inch Compact Flange Master Cylinder Kit, Banjo Outlet, Black Finish

This thirteen-sixteenths-inch Compact Remote master fills the bore-size step between the three-quarter- and seven-eighths-inch versions. The flange-mounted cylinder comes with two reservoir sizes, a hose, adapters and supports for arranging the fluid supply around the installation. From calipers and rotors to master cylinders, valves, brake lines and fittings, Wilwood Engineering's range covers disc brake systems and service components. Bill Wood founded the company in 1977; it is based in Camarillo, California and designs and manufactures for street-performance, specialized and motorsport applications. All component choices need to account for the complete system.

Fitment & Compatibility

Confirm that the selected bore and 1.12-inch travel meet the connected circuit's volume requirements. The pressure connection is a 3/8-24 banjo port, requiring a separately selected fitting rather than a flare nut threaded directly into the cylinder. Provide a rigid mount and free return of the piston and pushrod.
