Attention! 1. Brake pads are changed only as a set for one axle.
2. With each replacement of the drum brake pads, the return and clamping springs of the pads also change. Due to the continuous heating/cooling that the springs are subjected to, they lose their elasticity and over time the pads touch the drums, causing them to wear out.
1. Loosen the wheel nuts, raise the rear of the car.
2. Remove rear wheels.
3. Remove the drum (or hub, if a fully unloaded axle shaft is installed on the vehicle). On a vehicle with semi-unloaded axle shafts, the drum may not be removable. In this case, pour penetrating liquid between the axle shaft flange studs and the drum holes and tap the drum from the inside along the contour.
4. If the pads interfere with the removal (a wear notch has formed on the drum), then remove the plug from the brake shield (preventing it from falling inside the drum) and bring the pads together. To do this, remove the regulator lock from the gear wheel and turn the regulator gear wheel counterclockwise with a screwdriver (see photo).
5. Further procedures for replacing the pads are illustrated in the photo.
6. Clean the drum and check the condition of the surface. Check the ovality of the drum; in case of severe damage, grind the drum. If after turning the diameter is greater than the limit, replace the drum (see photo),
7. If there are traces of brake fluid leakage from the wheel cylinder, then replace the cylinder as an assembly, or remove and replace worn or damaged parts.
8. Check up an inhaling of bolts of fastening of a board of a brake. Clean the brake shield from dirt and corrosion.
9. Install the drum. Adjust the initial gap between the shoes and the drum. To do this, spread the pads until they come into contact with the drum by turning the toothed nut through the opening in the brake shield. When finished, replace the plug of the opening in the brake shield.
10. Install the wheel, tighten the nuts and lower the vehicle. Check brake pedal travel. If the brake pedal approaches the body floor at the end of the stroke, the brakes need to be re-adjusted. When finished, check the operation of the brakes before leaving.
