Fitment & Compatibility
Check the existing Ford Bronco brake conversions against the dimensions above. The hub flange and rotor attachment are separate interfaces and both must match the intended brake package. The parking-shoe diameter, anchor arrangement and complete drum-in-hat mechanism must match. A bare hat is not a complete parking-brake assembly.
