Wilwood Mustang-Style Compact Tandem Master, One-Inch Bore, Chrome Powder and Eyelet

This chrome powder-coated Compact Tandem master includes the eyelet pushrod for the specified classic Ford manual-pedal arrangement. Its one-inch bore supplies two independent circuits from the integral reservoir, with optional outlet locations on both sides of the housing. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. Its disc brake design and manufacturing range includes valves, master cylinders, calipers, brake lines, rotors and fittings for street-performance, specialized and motorsport use. These parts are selected together so the completed braking system has the required hydraulic and mechanical arrangement.

Fitment & Compatibility

Verify the actual manual pedal against the Mustang-style geometry, including the master page's 1964–1972 reference. The broader Ford flyer identifies additional compatible pedal arrangements but does not remove the need for measurement. Check full stroke, free return and the supplied flare-adapter sizes before connecting the brake lines.
