1. Inspect the fluid level in the brake master cylinder reservoir (1).

•	If the brake fluid level is midway between the maximum [dash ] fill level and the minimum allowable level, no brake fluid needs to be removed from the master cylinder reservoir (2) before proceeding.

Important: DO NOT completely empty the master cylinder reservoir (2) or remove any brake lines otherwise complete bleeding of the braking system will be necessary.

Important: DO NOT re use the removed fluid.

•	If the brake fluid level is higher than midway between the maximum [dash ] fill level and the minimum allowable level, syphon the brake fluid to the midway point using a hand vacuum pump (1) before proceeding.

2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
3. Remove the rear wheels. Refer to Tire and Wheel Removal and Installation.

1. Inspect the fluid level in the master cylinder reservoir.

•	If the brake fluid level is midway between the maximum fill level and the minimum allowable level, no brake fluid needs to be removed from the master cylinder reservoir before proceeding.

Important: DO NOT re-use the removed fluid.

•	If the brake fluid level is higher than midway between the maximum fill level and the minimum allowable level, syphon the brake fluid to the midway point using a hand vacuum pump before proceeding.

2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
3. Remove the front wheels. Refer to Tire and Wheel Removal and Installation.



4. Install 2 wheel nuts (1), in reverse, to opposite wheel studs to retain the brake rotor to the rear wheel hub.
5. Place a drain tray beneath the brake caliper assembly.

Important:  Install a rubber cap or plug on the exposed brake hose end in order to prevent fluid loss and contamination.

Important: Copper brake hose sealing washers become work hardened due to the heat generated with brake applications and will not reseal. Install NEW copper brake hose sealing washers whenever the brake hose to brake caliper banjo bolt is removed.

Important: To facilitate removal of the brake caliper, the reversed wheel nuts holding the brake rotor in position will need to be loosened and the brake pads fully pushed back against the pistons within the caliper.




6. Remove the brake hose to brake caliper banjo retaining bolt (1) and remove the brake hose (2) from the brake caliper (4).

Discard the washers.

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.

Notice: When adding fluid to the brake master cylinder reservoir, use only Holden specification number HN 1796 (Super DOT 4/DOT 4 Plus) brake fluid from a clean, sealed brake fluid container. The use of any type of fluid other than the recommended type of brake fluid may cause contamination which may result in damage to the internal rubber seals and/or rubber linings of hydraulic brake system components.

1. Clean the brake caliper mounting surfaces and brake caliper mounting threads using brake clean and a thread chaser (M12x1.5) to remove the remaining adhesive and avoid thread damage during bolt installation.
2. Check the serviceability of the brake pads. Refer to Brake Pad Inspection.

Important: Each inner and outer brake pad should be installed and removed in its original position. To decrease the risk of installing the brake pads in the wrong position, index the brake pads according to their installed position. Failure to install the brake pads in their correct position will cause the brake pads not to seat correctly in the brake caliper.

3. Install the existing or NEW brake pads if required. Refer to Rear Disc Brake Pads Replacement.
4. Position the brake caliper over the brake rotor. The brake rotor may need to be moved forward to allow clearance for placement of the brake caliper.

Notice: Refer to Fastener Notice in the Preface section.





Important: Under no circumstances is an impact wrench to be used on the following bolts.

5. Install the NEW brake caliper to knuckle retaining bolts (3).
