Replacement
1. Loosen the wheel nuts, lift the rear of the car. Remove the rear wheels.
2. Remove the drum. 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. As a last resort, move the drum by evenly screwing the bolts into the special threaded holes.
3. If the brake shoes interfere with the removal, remove the plug from the brake shield and bring the shoes together. To do this, move the regulator lever away from the toothed wheel and rotate the toothed wheel of the regulator counterclockwise with a screwdriver.
4. Clean the brake from dust and dirt. Check and replace the pads in accordance with the attached pictures.
5. Disconnect the spring from the front shoe.
6. Remove the front shoe pressure spring by pressing on the cup and turning it 90°.
7. Remove the lower spring.
8. Remove the rear shoe pressure spring.
9. Disconnect the regulator lever spring.
10. Disconnect the small crank cable.
11. Remove the regulator.
12. Remove the governor lever axle split lock washer from the rear shoe.
13. Remove the split washer from the handbrake lever axle.
14. Knock the axle out of the old block and press it into the new one (if the axis is missing).
15. With the lever positioned on the axle of the new pad, compress the split washer.
16. Install the regulator lever and secure with a new split washer. Install the spring.
17. Lubricate the friction surface of the shoe with high-melting grease. Clean and lubricate the moving part of the adjusting pin.
18. Disconnect the regulator and spring.
19. Install the assembled lever onto the brake shield and secure by installing the pin, spring, thrust washer and cup.
20. Attach the lower spring.
21. Install the shoe by engaging it with the regulator.
22. Place the tension spring on the other shoe.
23. Secure the shoe with a pressure spring.
24. Clean the drum and check the surface condition. Check the drum ovality, if there is severe damage, regrind the drum. If after regrinding the diameter is greater than the maximum, replace the drum.
25. Repeat these steps for the other wheel brake.
26. Adjust the handbrake crank (1 – spring, 2 – cotter pin, 3 – axle). To do this, disconnect the cable. Move the crank in direction A until it stops against the shoe (gap B = 0).
27. Loosen the lock nut and set the clearance C by rotating the bolt. Tighten the lock nut. Attach the spring and cable. Perform the adjustment for the other wheel.
28. Make sure the adjuster pin rotates by moving the handbrake lever inside the car.
29. Install the drums. Press the brake pedal several times. Then spread the shoes until they touch the drum by turning the adjuster gear through the hole in the brake shield with a screwdriver. Move the shoes slightly so that the drum can rotate freely. Install the plug.
30. Then assembly is performed in reverse order. Check the position of the pedal. If the pedal is too close to the floor, then while reversing, press the brake pedal several times to adjust the gap between the pads and drums using the automatic regulator (only works when reversing).
