Caution! Loosen and tighten the wheel mounting bolts only with the vehicle on the ground. Tightening torque of the bolts is 65–95 N·m (6.5–9.5 kgf·m).
Warning! Do not use gasoline, diesel fuel or any other mineral solvents to clean brakes.
Attention! When installing old pads, replacing the front and rear pads with each other, as well as between the left and right wheels, is not allowed. This may lead to uneven braking.
Caution! Brake pad sets must be replaced simultaneously on both sides of the vehicle.
Attention! If the brake fluid level in the reservoir is at or near the "MAX" mark, pump out some of the fluid from the reservoir. Otherwise, it will spill over the edge when installing new pads.
Note: When replacing the shoes, also inspect the brake drum. Measure the diameter of the drum working surface with a caliper. The maximum permissible drum diameter is 201.5 mm. If the diameter is equal to or greater than the maximum permissible, replace the drum. If there are marks, the drum can be bored to a diameter of 201 mm. It is recommended to replace the drums on both sides at the same time.
1. Put the car in first gear and chock the front wheels. Raise and support the rear of the car. Remove the wheel.
2. Wash with detergent and dry the brake mechanism.

10. Remove the rear shoe guide spring.
11. Remove the rear shoe by disconnecting the drive lever from the parking brake cable end.
12. Remove the cotter pin from the rear shoe.
13. Remove the thrust washer.
14. Press the pin and remove the drive lever from the shoe. Remove the pin from the shoe.
15. Check the thickness and condition of the brake pad friction linings.
16. Install new pads in reverse order. When installing, insert the upper toes of the pads into the piston grooves.
17. Before installing the drum, use two tire irons to push the brake shoes together and install the drum in the reverse order of removal.
18. Install the wheel and lower the car to the ground. Then press the brake pedal several times to set the piston to the working position. Check the brake fluid level in the reservoir and top up to the norm if necessary.
