F 250 2WD Pickup V8-7.3L DSL Turbo VIN F (1994)
With both types of brake lathes, set cutting tool to just contact the high spots on the front disc brake hub and rotor then adjust cutting tool to the
minimum depth required to clean up the front disc brake hub and rotor face. The total material removed (combination of both sides) must not
exceed the minimum discard thickness that is marked on the inside of the front disc brake hub and rotor.
To improve initial brake pedal feel and surface finish on a machined front disc brake hub and rotor, lightly sand rotor surface with 120 grit paper
prior to road testing.
Removal
1. Raise the vehicle until the tire clears the floor and remove the wheel and tire assembly.
2. Remove the brake caliper and secure to the underbody to prevent damage to the brake hose. It is not necessary to disconnect the hose from the
caliper. Do not let the caliper hang with its weight on the brake hose or the hose may become stretched, twisted or ruptured.
3. Remove the grease cap, cotter pin, retainer adjusting nut and washer.
4. Remove the outer bearing cone and roller.
5. Pull the hub and rotor off the spindle and remove and discard the grease seal.
6. Remove the inner bearing cone and roller from the hub. Remove all traces of old lubricant from bearings, hub and axle spindle.
Runout Check
Rotor Run-out Check
NOTE: Whenever brake front disc brake hub and rotor has been separated from hub face, clean any rust or foreign material from mating surface on hub
face and front disc brake hub and rotor. Failure to do this may result in increased lateral runout of the front disc brake hub and rotor and brake pulsation.
Install front disc brake hub and rotors on hubs and hold in place by using inverted wheel lug nuts and washers to seat front disc brake hub and rotors to
hubs. Tighten wheel lug nuts to 115-142 Nm (85-105 ft lb).
Using a dial indicator D78P-4201-B, or equivalent, measure front disc brake hub and rotor lateral runout as shown. The dial indicator should be centered
on brake surface. Rotate front disc brake hub and rotor while measuring runout. If runout is greater than 0.08mm (0.003 inch), front disc brake hub and
rotor must be repositioned (indexing) on hub to obtain the lowest possible runout.
