Check and replacement
1. Remove the brake disc.
2. Clean the handbrake mechanism.

4. Remove the handbrake springs.
5. Remove the pad spacer.
6. Remove the rear pad retainer spring.
7. Remove the rear shoe and regulator.
8. Remove the front shoe pressure spring, disconnect the cable from the lever and remove the shoe.

10. Move these parts to a new block and crimp the washer.
11. Lubricate the friction surface of the brake shield and the threads with a thin layer of refractory grease.
12. Lubricate the sliding surface of the regulator with a thin layer of refractory grease in the indicated places.
13. Attach the cable to the lever and install the front shoe.
14. Secure the block with a spring.
15. Put on the lower spring and install the regulator.
16. Install the rear pad.

24. Install the caliper bracket, tighten the bolts to the specified torque.
25. Install the wheel.
26. Check the number of clicks of the handbrake lever before full braking, which should be 5. Otherwise, adjust (see subsection 8.13).
27. To break in the brake pads, proceed as follows.
28. Driving at a speed of 50 km/h on a flat, dry highway, apply the brake by applying a force of 8 kgf to the lever and drive for about 0.5 km, then release the lever.
29. Repeat this procedure 2-3 times, allowing the pads to cool beforehand.
