Wilwood One-Inch Compact Tandem Master, Chrome Powder-Coated, No Pedal Rod

This bright Compact Tandem master uses a one-inch bore and a rodless actuator interface. The chrome powder-coated aluminum body carries primary and secondary fluid chambers, with alternate side ports to accommodate the chosen line routing. The broader Wilwood Engineering range includes calipers, brake lines, rotors, valves, fittings and master cylinders for disc brake systems. Established by Bill Wood in 1977 and based in Camarillo, California, Wilwood designs and manufactures for motorsport, street-performance and specialized applications. Correct component selection considers the complete system's geometry and hydraulic requirements.

Fitment & Compatibility

Match the master to the actual manual or assisted brake system and verify actuator depth before installation.

The flange accommodates 3.22–3.40-inch centers, but pedal travel and fluid demand must also agree.
