Product details
This chrome powder-coated master combines an oval dual reservoir with a fifteen-sixteenths-inch bore. It omits the pedal rod, making the actuator interface a separate installation choice for an appropriately designed manual or assisted brake system. 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
Match the flange spacing, piston-recess engagement and available travel in the actual vehicle. Use the provided inverted-flare adapters and plugs for the selected side outlets, with proper double-flared pressure lines. The integral 8.0- and 4.8-ounce chambers provide fluid reserve; they do not determine front-to-rear pressure bias.
