Product details

A chrome powder-coated master with a 1-1/8-inch bore is supplied with the specified Mustang manual pushrod. This compact tandem package locates the combination valve on the left and includes its preformed connecting tubes. Wilwood Engineering's disc brake systems bring together calipers, rotors, valves, master cylinders, fittings and brake lines. Founded by Bill Wood in 1977 and based in Camarillo, California, the company designs and manufactures products for motorsport, street-performance and specialized applications. The installed system determines which individual component is appropriate.

Fitment & Compatibility

Match the documented classic Mustang installation. Check the larger bore's relationship to pedal leverage, caliper fluid demand and available cylinder stroke.

Wilwood’s kit summary gives a 1964–1973 Ford/Mustang range, while the corresponding bare-master family identifies 1964–1972. Confirm the actual manual pedal, supplied eyelet and mounting geometry, particularly for 1973, before ordering.
