Maintaining the speed, tighten the brake by one tooth and drive another 400 m. Release the brake and let it cool. This removes any rust that may form on the friction surface and wear products.
Adjustment of the parking brake is necessary when:
- Replacing brake pads.
- Replacement of brake drums/rear brake discs.
- Installing the adjusting device back.
- Too much travel for the brake lever (over 10 teeth).
- Replacing the brake drive cable.
The parking brake cables and all moving brake components must move easily.
Adjustment
1. Loosen one mounting bolt on each rear wheel.
2. Raise and support the rear of the vehicle on stands.
3. Remove the cover of the parking brake lever "1" at the top and pull it forward through the handle.
Service stations use a special tool BMW-341030 to adjust the parking brake.

5. Completely unscrew one mounting bolt on each rear wheel. Rotate the wheel so that the hole is vertical at the bottom. Shine a flashlight into the hole; the adjusting nut should be visible in it.
The wheel should not be removed as shown in the illustration.

If the adjusting nut on the left side of the car turns in the direction of the arrow, the brake shoes are pressed against the drum. On the right side, the screwdriver turns in the opposite direction.
7. After adjustment, check whether the wheels rotate freely, if necessary, unscrew the adjusting nuts again. The wheels must rotate freely.
