NOTE: If the vehicle pulls to one side or makes unusual noise when braking, check the condition of the brake pads.
1. Place the vehicle on a lift or jack (stands).
2. Remove the front wheel.
3. Check the condition of the brake pads through the hole in the brake caliper housing. If the thickness of the friction linings is less than the permissible value (Table 4.5), replace the brake pads (see "Replacing the front wheel brake pads").
4. Measure the thickness of the brake disc. If its thickness is less than the permissible value (see Table 4.5), replace the brake disc (see "Replacing the brake disc").
Table 4.5 Dimensions of brake pads, discs and drums, mm
NOTE: On vehicles with rear disc brakes, similarly check the brake pads and rear brake disc for wear.
5. To check the degree of wear of the rear brake pads, remove the rear wheel and brake drum (see "Removing and installing the brake drum").
6. Measure the thickness of the friction lining together with the base. If the thickness is less than the permissible value (see Table 4.5), replace the pads (see "Replacing the rear wheel brake pads").
NOTE: Replace the pads in the following cases:
- the thickness of the friction linings is less than 1 mm;
- the surface of the linings is oily;
- the pads are not firmly connected to the base.
7. Measure the diameter of the working surface of the brake drum. If it is larger than the permissible value (see Table 4.5), replace the drum (see "Removing and installing the brake drum").
NOTE: The maximum allowable working diameter of the brake drum is stamped on its inside.
