Wilwood Remote Tandem Master, 1-1/8-inch Bore, Chrome Powder Coating, Without Rod

The largest bore in this rodless Remote Tandem range is housed in chrome powder-coated aluminum. Separate seven-ounce reservoirs serve the two circuits, while the threaded pressure ports on both sides permit the required outlet and plug arrangement. The disc brake systems Wilwood Engineering designs and manufactures include calipers, rotors, master cylinders, brake lines, valves and fittings. The company dates to Bill Wood's founding in 1977 and is based in Camarillo, California. Motorsport, specialized and street-performance applications all call for parts matched to the operating requirements of the full system.

Fitment & Compatibility

Provide a compatible pedal or booster actuator and check its engagement without preloading the piston. Use the appropriate flare adapters, secure the two reservoir feeds and allow full stroke before any pedal stop. This is a custom-system component rather than a model-specific replacement based solely on mounting dimensions.
