1. Place the car on a lift or jack (coasters).
2. Remove the front wheel.
3. Check the condition of the pads through the hole in the brake caliper housing. If the thickness of the friction linings is less than the permissible (tab. 4.3), replace the brake pads (see «Replacing the brake pads of the brake mechanism of the front wheel»).
Table 4.3. Dimensions of brake pads, discs and drums
4. Measure the brake disc thickness. If its thickness is less than the allowable (see table. 4.3), replace the brake disc (see «Brake disc replacement»).
5. To check the degree of wear of the brake pads of the rear brake mechanism, remove the rear wheel and brake drum (see «Removal and installation of a brake drum»).
6. Measure the thickness of the friction lining together with the base. If the thickness is less than the allowable (see table. 4.3), replace pads (cm «Replacing the brake pads of the brake mechanism of the rear wheel»).
Note. Replace the pads in the following cases: – the thickness of the friction linings is less than 1.5 mm; – the surface of the overlays is oiled; - the pads are loosely connected to the base.
7. Measure the diameter of the working surface of the brake drum. If it is more than allowed (see table. 4.3), replace the drum (see «Removal and installation of a brake drum»).
