Wilwood One-Inch Side-Mount Compact Master Kit with Banjo Port and Two Reservoir Sizes

This one-inch Compact Remote master attaches through its side bosses rather than a two-bolt end flange. The long pushrod and choice of supplied reservoir sizes help define an installation where pedal location and fluid-container clearance must be planned together. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. The company designs and builds disc brake systems, with calipers, master cylinders, rotors, brake lines, fittings and valves serving street-performance, motorsport and specialized applications. Selecting an individual part requires checking how it works with the rest of the braking assembly.

Fitment & Compatibility

Confirm the three-inch mounting-hole spacing, 5/16-24 rod end and available piston travel. Use the proper separately supplied banjo fitting at the 3/8-24 pressure port; a same-thread inverted-flare line does not provide the required seal. Follow the instructions when arranging the low-pressure hose and remote reservoir bracket.
