Wilwood Compact Flange Master Kit, 5/8-inch Bore and Banjo Outlet, with Two Reservoirs

The five-eighths-inch version of Wilwood's Compact Remote flange master uses a straight-thread banjo outlet. Two supplied plastic reservoirs let the installer choose a 7- or 10-ounce container and arrange it directly above the cylinder or remotely with the supplied feed hardware. Wilwood Engineering designs and manufactures disc brake systems in Camarillo, California. Bill Wood founded the company in 1977; its range now encompasses calipers, rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. Each component must suit the hydraulic and mechanical requirements of the complete system.

Fitment & Compatibility

Use the 2.25-inch flange centers and match the 1.12-inch stroke to the pedal and hydraulic demand. The 3/8-24 banjo port requires the correct banjo fitting and sealing washers, sold separately; it is not an inverted-flare outlet. Route the low-pressure reservoir hose independently of the pressurized brake or clutch line.
