2. Jack up and support the rear of the car so that the rear wheels do not touch the ground. Block the front wheels, engage gear and release the handbrake.
3. Loosen the nuts on one of the rear wheels and remove the wheel. Loosen and remove the 2 countersunk head screws securing the brake drum and remove the drum.
4. If the drum cannot be removed, then most likely the brake pads need to be moved away from it. Remove the plug from the drum support disk (located at the lower rear of the disk) and insert a screwdriver into the resulting hole. Press the handbrake lever located in the drum and move it to the side in order to move the shoes away from the drum. Replace the plug.
5. After removing the drum, thoroughly clean the rear brake from dust and be careful not to inhale it. To clean the drum, you can use a dry paintbrush and a damp cloth.
6. Inspect the rear brake for brake fluid leaks from the brake cylinder and traces of grease leaks from the wheel bearings. Check the condition of the rubber boots on the cylinder and the general condition of the moving parts. If fluid or lubricant leaks are detected, the source of the leak must be localized and eliminated. If at least one brake lining needs to be replaced, all 4 will need to be replaced. Inspect the linings for wear, and if the thickness of the friction material on at least one lining has reached 2.5 mm, the linings must be replaced. The procedure for replacing wheel bearings and seals is described in chapter 7.
7. Before installing the drum, inspect it for grooves, traces of corrosion and other defects. If the drum has defects caused by wear under the influence of the pads, you can take the drum to a specialized workshop.
8. Perform similar operations on the second rear wheel. Installation of brake drums is carried out in reverse order. Install the wheels in place and secure them with nuts. Lower the vehicle to the ground and tighten the wheel nuts to the specified torque. Press the brake pedal several times to adjust the brake pads, and then adjust the handbrake (see section 4).
