Attention! Dust generated during normal operation of the brake system is harmful to health. Never blow it out with compressed air or inhale it. Always use a certified filter mask when working on brakes. Under no circumstances should you use petroleum-based solvents to clean the brake system. Use only brake cleaner!
Attention! Parking brake pads should be replaced on both wheels at the same time; never replace pads on only one wheel.
1. Remove the brake disc (see paragraph 5).
2. Estimate the thickness of the friction material on the pads. If the thickness of the lining as a result of wear has reached 0.8 mm or has become even less, the pads should be lured.
3. Remove the hub assembly with bearing (see chapter 10).
Note. It is possible to perform the pad replacement procedure without removing the hub/bearing assembly, although the working space is quite limited.
4. Wash the brake elements with a brake cleaner (pic. 10.4).

5. When performing the procedure for replacing brake pads, follow the accompanying photos (pic. 10.5, a-x). Do not break the prescribed sequence and read the captions under each figure.

6. Install the brake disc. Temporarily screw in the three wheel nuts, not the studs, to hold the disc in place.
7. Remove the plug from the hole on the brake disc. Adjust the clearance between the shoes and the parking brake drum by turning the adjuster with a brake adjuster or a screwdriver until the shoes come into contact with the drum built into the disc and the disc cannot be rotated (pic. 5.6, a, b). Unscrew the adjuster by eight teeth, and then install the plug in the hole.
8. Install the caliper bracket (pic. 5.2, b) and brake caliper (see paragraph 4). Tighten the bolts to the specified torque given in the Specifications at the beginning of this chapter.
9. Fit the wheel and tighten the wheel nuts to the specified torque as specified in Specifications at the beginning of this chapter.
10. Apply the parking brake and count the number of clicks as it moves. Should be about 5-7 clicks. If it is not leaking, adjust the parking brake as described in next paragraph.
