Follow the same tightening sequence for the front wheel hub extension that is used on an eight lug wheel.
Install the front wheel hub extension nuts.
^
Tighten the front wheel hub extension nuts to 130 Nm (96 ft. lbs.).
11. Install the tire and wheel assembly.
12. Lower the vehicle.
13. With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
14. Slowly release the brake pedal.
15. Wait 15 seconds, then repeat steps 13-14 until a firm pedal is obtained. This will properly seat the brake caliper pistons and brake pads.
16. Fill the master cylinder reservoir to the proper level with clean brake fluid. Refer to Master Cylinder Reservoir Filling in Hydraulic Brakes.

Removal Procedure
1. Release the park brake.
2. Raise and suitably support the vehicle. Refer Vehicle Lifting
3. Remove the tire and wheel assembly.
4. Mark the relationship of the rotor to the hub.
5. Install a C-clamp over the body of the brake caliper, with the C-clamp ends against the rear of the caliper body and the outboard disc brake pad.
6. Slowly tighten the C-clamp until the pistons are pushed into the caliper bores enough to remove the caliper from the pads.
7. Remove the C-clamp from the caliper.
8. Remove the brake caliper bracket mounting bolts.
9. Notice:
Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose
is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause
damage to the brake hose and in turn may cause a brake fluid leak.
Remove the brake caliper and brake caliper bracket as an assembly and support with heavy mechanic's wire or equivalent. DO NOT disconnect the
hydraulic brake flexible hose from the caliper.
10. Remove the rotor retaining push nuts from the wheel studs, if applicable.
11. It may be necessary to strike the end of the hub or the rotor with a dead blow hammer to separate the rotor from the hub.
