Wilwood Ford Mustang-Style Remote Master, 7/8-inch Bore, Chrome Powder with Pushrod

Chrome powder coating finishes this remote-reservoir tandem master, which includes a Ford-style manual-pedal eyelet. The seven-eighths-inch bore and two separate fluid containers support a custom dual-circuit conversion when the linkage and hydraulic requirements agree. Based in Camarillo, California, Wilwood Engineering has designed and manufactured disc brake systems since Bill Wood founded the company in 1977. Its fittings, valves, calipers, brake lines, master cylinders and rotors are used across motorsport, street-performance and specialized applications. Matching a component means checking both its own specification and the braking assembly around it.

Fitment & Compatibility

Compare the installed factory manual pedal to the supplied eyelet and the 3.22–3.40-inch flange span. The exact product page cites 1965–1973 Mustang/Ford applications; the Ford-style flyer gives broader 1960–1973 pedal compatibility. Confirm the individual vehicle and provide suitable separate front and rear circuit plumbing.
