Wilwood Front Two-Piston Drag Brake Kit, Ford Pinto/Mustang II and Mercury Bobcat (1971–1980), 10-Inch Drilled

This Wilwood front drag kit uses two-piston Dynapro Single calipers over drilled 10.00-inch solid steel rotors. Replacement five-lug hubs adapt the specified Pinto/Mustang II spindle arrangement for competition use. The 0.32-inch rotor width and two-piston layout set it apart from the larger four-piston Dynalite kit. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Select the correct 1971–1980 Pinto, 1974–1978 Mustang II or 1975–1980 Bobcat application and compare the original disc/drum spindle. The supplied hubs support five-lug configurations rather than retaining four-lug wheels. Check the +0.41-inch wheel offset change and the clearance diagram for the chosen wheel. Hydraulic lines are separate, and any master-cylinder pushrod adjustment depends on the existing hydraulic setup.
