Rear Brake Drums — Removal, Inspection and Installation (Opel Astra G)

1. Raise the rear of the car and place it on stands. Remove the wheel.

2. Release the handbrake.

3. Loosen the screws and remove the drum (see photo). If the drum cannot be removed, the shoes should be brought together. To do this, remove the plug from the hole in the brake shield. Insert a screwdriver into the hole and move the parking brake shoe drive lever.





If necessary, loosen the parking brake cable adjusting nut.

4. Carefully clean the drum. Check the drum for cracks and signs of wear.

Check the condition of the inner surface; if there are traces of deep wear, the drum must be replaced. If a ridge has formed on the inner surface due to friction between the pads, both drums must be ground to the same diameter. If after grinding the inner diameter of the drum exceeds the maximum permissible value, replace both drums together with the pads.



5. Install the drum in the reverse order. When finished, spread the shoes by pressing the brake pedal several times. Adjust the parking brake (if the adjusting nut was loosened).
