1. Left wheel; 2. Right wheel; 3. To the front of the car
Position of the pads after assembly
1. Left wheel; 2. Right wheel; 3. To the front of the car
Attention! The pads are changed only as a set for one axle.
Together with the shoes, the tension springs are also changed, which, subjected to periodic thermal loads, gradually lose elasticity and do not provide sufficient removal of the shoe from the drum. As a result, the drum touches the shoes, causing their premature wear.
Replacement
1. Loosen the wheel nuts, lift the rear (or front) part of the car.
2. Remove the wheels.
3. Release the handbrake.
4. Mark the position of the drum, unscrew the screws (if provided) and remove the drum.
5. If the drum cannot be removed, pour penetrating liquid between the axle flange studs and the drum holes and tap the drum from the inside along the contour.
6. If this measure does not produce results, then move the pads together.
7. To do this, on brakes with horizontal pads, remove the plug from the brake shield and rotate the regulator gear wheel with a screwdriver.
8. On vertical brakes, use a narrow-blade screwdriver to pry the adjuster lever away from the gear wheel and rotate the adjuster gear wheel with another screwdriver.
Brake with horizontally positioned pads
9. Remove the tension spring.
10. Remove the brake shoe pressure springs by pressing on the cup and turning it 90°.
11. Remove the pads together with the lower spring.

28. If after turning the inner diameter of the drum is greater than the maximum (indicated on the drum), replace the drum.
29. Install the drum and check the brake adjustment.
