Product details

This Bronco-pattern rear conversion combines black four-piston Dynapro calipers and plain 12.19-inch rotors. Internal parking-brake shoes provide the mechanical function, with the bracket selected for a Small Ford housing end. 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

Confirm the Small Ford Bronco flange and 2.36-inch axle offset using DS1015. The specified 5 x 5.50-inch rotor pattern, axle register and cable linkage must match the actual rear axle.

In addition to the bracket pattern and measured offset, inspect the axle flange profile. Its outside diameter may not exceed 6.61 inches and it requires the documented 0.050-inch x 45-degree chamfer. The instructions show a 2.88-inch axle register with the applicable centering provision.

The installation reference identifies Small Ford Bronco rear applications with 2700-lb axle/10-inch drums for 1966–1973 and 2900-lb axle/10-inch drums for 1974–1975. The measured2.36-inch offset and actual housing flange still govern selection.

Hydraulic hoses/fittings and parking-brake cables, adapters and cable hardware are not included. Choose a compatible cable arrangement for the internal parking brake; universal cable systems may require vehicle or cable modifications.
