USEFUL TIP: Perform the work on the vehicle with the rear wheels raised (on a lift or the vehicle supported by a jack). The parking brake lever should be lowered all the way down (the vehicle should be unbraked).
You will need: a lug wrench, a flat-blade screwdriver.
1. Engage first gear and place chocks under the front wheels.
2. Remove the decorative cap of the rear wheel (see "Changing a Wheel").
3. Raise the rear wheel and place the rear of the vehicle on the side of the drum being removed on a support. Remove the rear wheel (see "Changing a Wheel").
4. Pry it off with a screwdriver..
5. …remove the retainer from one of the studs…
6. …and remove the brake drum.
NOTE: After prolonged use, a ridge will form on the outer edge of the drum working surface due to wear, making it difficult to remove the drum. In this case, loosen the parking brake cable (see "Adjusting the Parking Brake Drive").
WARNING: Do not press the brake pedal with the brake drum removed, as this may cause the pistons to completely come out of the slave cylinder and brake fluid to leak out of the hydraulic system.
7. Measure the diameter of the working surface with a caliper. If the diameter exceeds the maximum permissible value, the drum must be replaced.
NOTE: The maximum permissible wear diameter (230.2) is marked on the inner surface of the drum in the casting.
8. Inspect the working surface of the drum. It should be flat and smooth, without ring marks and clearly visible ovality (the ovality should be no more than 0.5 mm, it can be determined by the unevenly worn working surface of the drum). If the ring marks are very deep or the uneven wear of the working surface is clearly visible, the drum will have to be replaced with a new one.
WARNING: Replace brake drums in pairs (left and right at the same time).
HELPFUL TIP: Inspect the surface of the brake pads.
HELPFUL TIP: If the linings are wet with brake fluid, the slave cylinder seals are not tight, replace it (see "Replacing the rear wheel brake slave cylinder").
9. Remove and check the second brake drum in the same way.
10. When installing the old drum, use a file to remove the ridge on the working surface of the drum that has formed as a result of wear.
11. Return the clearance adjuster to its original position (see paragraphs 8 and 9 "Replacing the brake pads of the rear wheel brake mechanism").
12. Install the drum in the reverse order of removal.
13. Adjust the clearance between the brake shoes and the drum by pressing the brake pedal several times.
14. Install the wheel and decorative cap (see "Changing a Wheel").
15. Check the ease of rotation of the wheel. Slight contact of the drum with the pads is permissible.
