All vehicles require the front brake disc replacement method to start with positioning the
Brake Caliper away from the brake hose unless the brake caliper can hang freely from the brake hose. Take out the two caliper anchor plate bolts before setting aside the brake caliper and anchor plate assembly while securing it with mechanic's wire. When dealing with single rear wheel vehicles a penetrating and locking lubricant should be added to the brake disc-to-
Wheel Hub mating surfaces while using a wheel stud mark on the corresponding brake disc stud hole to achieve the lowest front brake disc runout during assembly. When dealing with dual rear wheel vehicles follow this procedure: remove the hub extender nuts and the hub extender before treating the brake disc-to-wheel hub mating surfaces with penetrating and lock lubricant and noting the hub extender stud match with the corresponding brake disc extender stud hole. Wash away all rust and foreign items on the brake disc and hub using brake parts cleaner after you take off the front brake disc. Begin by using thin anti-seize lubricant on the hub flange while lining up disk marks with hub marks and putting the brake disc into position. Dual rear wheel vehicles require a hub extender that should be installed and tightened with 176 Nm of torque (130 ft. lbs.). Position brake disc caliper anchor plate before installing two bolts which need to be tightened at 225 Nm (166 ft. lbs.) for F-250 and F-350 models and at 400 Nm (295 ft. lbs.) for F-450 and F-550 models.
