For equivalent regional tools, refer to Special Tools .
Removal Procedure
- Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle .
- Remove the tyre and wheel assembly. Refer to Tyre and Wheel Removal and Installation .
- Remove the both brake hose bolts (1) attaching the hose to the rear brake calliper bracket.

- Remove the 4 wheel bearing/hub mounting bolts (1).
Caution: Support the brake calliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the calliper in this manner will cause the flexible brake hose to bear the weight of the calliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
- Without disconnecting the hydraulic brake flexible hose, remove wheel bearing/hub and brake assembly (2) upward and secure the wheel bearing/hub and brake assembly with heavy mechanics wire (1), or equivalent.
