4.3.26. Check of degree of wear of brake shoes, disks and drums
It will be required to you: caliper or ruler.
| Note If when braking the car takes away aside or extraneous noise is heard, check a condition of brake shoes. | 
1. Install the car on the elevator or a jack (supports).
2. Remove a forward wheel.
| 3. Check through an opening in the case of a brake bracket a condition of blocks. If thickness of frictional overlays of less admissible (tab. 4.3), replace brake shoes (see. "Replacement of brake shoes of the brake mechanism of a forward wheel"). | 4. Measure thickness of a brake disk. If its thickness of less admissible (see tab. 4.3), replace a brake disk (see. "Replacement of a brake disk"). | 
Table 4.3 Sizes of brake shoes, disks and drums, mm
| 5. For check of degree of wear of brake shoes of the back brake mechanism remove a back wheel and the brake drum (see. "Removal and installation of the brake drum"). | 6. Measure thickness of a frictional slip together with the basis. If thickness of less admissible (see tab. 4.3), replace blocks (see. "Replacement of brake shoes of the brake mechanism of a back wheel"). | 
| Note Replace blocks in the following cases: – thickness of frictional slips is less than 2 mm; – the surface of slips is greasy; – slips are unsteadily connected to the basis. | 
7. Measure diameter of a working surface of the brake drum. If it is more admissible (see tab. 4.3), replace a drum (see. "Replacement of the brake drum").
