Execution sequence
1. We prepare the car for work (see «Preparing the car for maintenance and repair»).
2. Remove the rear wheel (see «Wheel - replacement»).
3. To check the thickness of the brake pad lining, remove the plug from the brake shield.
4. Through the inspection hole in the shield, we visually determine the thickness of the brake shoe lining.
If the thickness of the brake pad lining is less than the allowable (see «Reference data»), we replace all brake pads of the left and right brake mechanisms (see «Rear brake pads - replacement»).
5. Install the brake shield plug.
Comment. This method does not make it possible to estimate the wear of the second brake pad (which may differ in case of malfunction of the wheel brake cylinder), wear of the brake drum and serviceability of the wheel brake cylinder. Therefore, it is better to remove the brake drum and carry out a full check.
6. Remove the brake drum (see «Rear brake drums - replacement»).
7. We measure the diameter of the brake drum, if it is larger than the allowable (see «Reference data»), replace the drums on both sides of the car (see «Rear brake drums - replacement»).
8. Determine the thickness of the brake pads, if it is less than the allowable (see «Reference data»), we replace all four brake pads of the left and right brake mechanisms (see «Rear brake pads - replacement»).
9. We check the absence of brake fluid leaks from the cuffs of the wheel brake cylinder.
10. We check the correct installation of the spring of the device for automatically adjusting the gap in the rear brake mechanism.
11. Slightly retract the pawl of the adjusting device and check the ease of rotation of the adjusting gear.
If the gear does not turn, the spacer bar must be removed (see «Rear brake pads - replacement») and repair or replace it.
12. We make sure that there are no traces of oil and other technical fluids on the brake drum and pads. If necessary, degrease them, for example, with a brake cleaner.
13. We assemble the brake mechanism and install the wheel.
14. Similarly, we check the brake mechanism of the second wheel.
