Wilwood Chrome Powder-Coated Remote Master with Pushrod, 7/8-inch Tandem Bore

This chrome powder-coated master moves the fluid storage into two remote containers instead of an integral reservoir above the bore. Its seven-eighths-inch piston size and included pushrod must be selected together with pedal leverage and the displacement needs of both brake circuits. 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

Use the supplied reservoir brackets, hose and feed adapters to establish secure fluid supplies. The 1/2-20 body ports accept the supplied inverted-flare line adapters; the quarter-inch feed hose is not a pressure line. Confirm full mechanical stroke and complete piston return at the installed pedal.
