Wilwood Front Dynapro Kit for Mustang II, Pinto and Bobcat Disc Spindles, Black, 11-Inch Rotors and Five-Lug Hubs

Black Dynapro dust-boot calipers, 11-inch plain rotors and five-lug hubs convert the documented Mustang II, Pinto and Bobcat disc-spindle arrangement. The supplied hubs change the wheel attachment from the original four-lug layout. Founded in 1977 under Bill Wood, Wilwood Engineering operates from Camarillo, California. The company designs and manufactures disc braking systems and components, including calipers, master cylinders, brake rotors, fittings, valves and brake lines. Its motorsport, specialized and street-performance range requires individual parts matched to the complete braking arrangement.

Fitment & Compatibility

Use the 1974–1978 Mustang II, 1974–1980 Pinto or 1975–1980 Bobcat disc-spindle row. DS1019 calls for compatible five-lug wheels and complete wheel-pad support. Inspect the original caliper ears for interference and trim only where the instructions require; retained four-lug wheels are incompatible.

Documented model groups, subject to each year, submodel and spindle/axle qualification: Ford Mustang II, Pinto; Mercury Bobcat.

Requires the documented original disc spindle and compatible five-lug wheels. Four-lug wheels are incompatible. DS1019/DS1020 calls for limited removal of original caliper ears only where they interfere; preserve the bracket mounting holes.

The installation reference distinguishes wheel-pad overhang from a supported stamped steel wheel. Overhang requires a 0.20-inch-thick steel spacer, 6.60 inches in diameter, part 300-11961 (listed in the installation parts list). A stamped wheel without overhang should instead use the separate 0.09-inch-thick, 6.15-inch-diameter shield 300-10716.

Flexible brake lines are not included. Original lines are not assumed to connect to the Wilwood calipers; select the application-specific or correctly sized universal hose and matching fittings.

Kit includes 5 lug hubs. Not applicable to 4 lug vehicles.

Universal Flexline kits available: 220-7056 (14"), 220-7699 (16") or 220-8307 (18"). Choose correct length for your application.

A separately selected master cylinder may require modification of the existing pushrod assembly; it is not supplied in this brake kit.

An independently added universal parking-brake cable system may require cable or vehicle modifications. It is separate from this front service-brake kit.
