All 1966 Ford F-100 pickup trucks were equipped with drum brakes. When the brake pedal is depressed, two brake pads expand and press against the inside of a brake drum. Over time, the brake drum becomes damaged from the tremendous pressure. In extreme circumstances, a damage brake drum will also cause the brake pads to wear out prematurely. Brake drums can sometimes be repaired by a process called "turning." If the brake drum is too damaged for repair, it must be replaced. In either event, the existing brake drum must first be removed.
Raise either the front or the back of the truck with a jack, depending on which end of the truck the brake drum will be removed from.
Place a single jack stand underneath the frame rail on each side of the truck, then lower the truck onto the stands.
Disengage the parking brake if the brake drum will be removed from the back of the truck.
Remove the lug nuts which secure the wheel and tire assembly to the tip of the axle shaft with a lug nut wrench.
Lift the wheel and tire assembly off of the axle shaft to expose the brake drum.
Pull the brake drum off of the axle shaft.
