Product details

Chrome powder coating gives this seven-eighths-inch Compact Tandem master its bright exterior. The integral fluid chambers eliminate separate reservoir hoses, while the included pushrod connects to a correctly designed manual pedal linkage. A disc brake manufacturer based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. It designs and manufactures calipers, rotors, brake lines, fittings, valves and master cylinders for street-performance, motorsport and specialized systems. The chosen service part must agree with the complete system's connections, dimensions and operating demands.

Fitment & Compatibility

Use the 3.22–3.40-inch flange range and check the actual installed rod length. The primary circuit should serve the axle with greater effective caliper piston area as detailed in the instructions. The 2:1 volume ratio does not replace a correctly selected proportioning valve or establish a 2:1 pressure bias.
