Remove the rear hub/drum or disc. Clean the axle and inspect the bearing contact surfaces for wear and damage. The spindle should be replaced with a new one if it is bent, damaged or worn. Disconnect the parking brake cable from the brake assembly. Disconnect and plug the rear brake line at the wheel cylinder. Remove the four backing plate mounting bolts and detach the brake assembly and spindle. The bolts may have Torx-type heads, which require a special tool for removal. Be sure to mark the location of any spindle shims. Place the shim(s) (if equipped), spindle and brake assembly in position, install the bolts and tighten them, following a criss-cross pattern. Connect the brake line and parking brake cable. Install the hub/drum or disc, bleed the brakes and adjust the parking brake.
