1. Remove the wheel and tire assembly. For additional information, refer to Section 204-04. 2. NOTE: Caliper is removed for clarity. Position aside the front disc brake caliper and anchor plate. 1. Remove the two front disc brake caliper anchor plate bolts. 2. Remove the front disc brake caliper anchor plate and position aside. 3. NOTE: Carry out this step for F-250 and F-350 4×4 SRW vehicles. Remove the rotor. 4. NOTE: Carry out this step for DRW vehicles. NOTE: If excessive force must be used during brake rotor removal, the brake rotors should be checked for lateral runout prior to installation. For additional information, refer to Section 206-00. Remove the eight hub extender nuts, the hub plate and the rotor. 1. Remove the eight hub plate nuts. 2. Remove the hub plate. 3. Remove the rotor. CAUTION: Due to the fit of the splines, the hub lock will be difficult to remove. Lifting or lightly prying (with a small bar) on the axle U-joint will ease removal. When prying on the cap/hub flange, work around the flange to uniformly withdraw the hub lock. 5. CAUTION: The service replacement kit includes two O-ring seals. One for testing the hub lock assembly and one for reassembly into the wheel hub. DO NOT REUSE O-RING SEALS. CAUTION: Always check the vacuum leak rate of the wheel end assembly when repairing or diagnosing the axle, wheel end or hub lock performance. Loosen each retainer screw one to two turns. ? Gently pry on the hub lock cap edge to release gasket adhesion. ? Remove and discard the retainer screws. ? While lifting/jiggling the axle U-joint, pull or uniformly pry the hub lock from the wheel hub.

Remove two-thirds of the brake fluid from the master cylinder. Raise the vehicle and suitably support. Refer to Vehicle Lifting. Mark the relationship of the wheel to the hub flange. Remove the Wheel. Refer to Tire and Wheel Removal and Installation in Wheels, Tires and Alignment. Important: Do not use a screwdriver or pry bar to compress the caliper piston into the caliper. Any damage to the piston boot could cause corrosive elements to enter the piston sealing area and lead to the piston seizing in the caliper bore. Important: Do not exceed more than 1 mm of piston travel. Damage to the internal adjusting mechanism may result. 5. Using a large C clamp compress the piston into the caliper until resistance is felt, but no more than 1 mm of piston travel in order to gain enough clearance to allow the caliper to pivot off the caliper bracket. 6. Disconnect the park brake cable (1) from the brake caliper. 7. 8. 9. 10. Remove the bottom caliper slide pin. Pivot the caliper body (6) upward. Remove the inboard (2) and outboard (3) pads from the anchor bracket (5). Remove and inspect the pad retainers (1). Important: Inspect the caliper bolt suspension boots for cuts, tears, or deterioration. if damaged, replace the pin boots. Refer to Caliper Bracket Overhaul. Inspect the piston boot for deterioration. If damaged, Refer to Caliper overhaul. Caliper pin bolt for damage or corrosion. Replace if damaged or corroded. Do not attempt to clean away corrosion. Corrosion is typically caused by damaged pin boots. Installation Procedure
