Wilwood Black 7/8-inch Remote Tandem Master with Ford Mustang Manual-Pedal Pushrod

This black Remote Tandem master includes the eyelet-style pushrod for the specified classic Ford manual pedal arrangement. A seven-eighths-inch bore works with two seven-ounce remote reservoirs, making pedal compatibility and reservoir placement separate installation checks. Disc brake systems and components are the focus of Wilwood Engineering's design and manufacturing work for street-performance, specialized and motorsport applications. Bill Wood founded the Camarillo, California company in 1977. Its master cylinders, calipers, fittings, valves, brake lines and rotors are chosen according to the needs of the complete brake system.

Fitment & Compatibility

Wilwood's exact page identifies 1965–1973 Mustang/Ford applications, while its Ford-style flyer describes compatible factory manual-pedal geometry across 1960–1973 Ford cars. Verify the actual pedal, eyelet and mounting dimensions instead of treating those broad ranges as universal vehicle fitment. Retain independent circuits and full piston travel.
