Product details
For an assisted system requiring the larger compact-tandem bore, this master provides a rodless interface and integral dual reservoir. The aluminum housing has a chrome powder finish and two-sided outlet options for adapting the pressure-line layout. Established in 1977 by Bill Wood, Wilwood Engineering designs and manufactures disc brake systems from its base in Camarillo, California. Calipers, fittings, rotors, valves, master cylinders and brake lines serve its motorsport, street-performance and specialized applications. The full assembly, including its mating connections and operating requirements, governs the correct part selection.

Fitment & Compatibility
Confirm the one-and-one-eighth-inch bore is suitable for the booster, pedal ratio and brake volume. Check actuator engagement without side interference or piston preload, then verify the entire stroke remains available. A separate combination valve may be required to set rear pressure for the vehicle's actual brakes.
