1. Inspect the fluid level in the master cylinder reservoir (2).

•	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 (2) 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 (1) before proceeding.

Important: Brake pads should always be replaced in axle sets.

2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.

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.

Important: Make sure shims are securely affixed to backing plate of the brake pads.

1. Clean the piston to brake pad contact faces as required.



2. Install the brake pads (1) into the brake caliper (2) against the caliper pistons.



3. Install the lower retaining pin (1) into the caliper body through both brake pads (4).

Important:: Arrow located on anti-rattle clip indicates direction of disc rotation. Make sure correct installation of the anti-rattle clip.

4. Install the anti-rattle clip (2) behind the lower retaining pin (1).
