1. Check thickness of brake shoes and, if necessary, replace them. |
| 2. If it is visually difficult to define thickness of brake shoes, remove a support and take brake shoes for further survey. Measure thickness of brake shoes, thus, if thickness of a frictional layer less admissible, replace a brake shoe. |
| 3. Measure thickness of brake disks by means of a micrometer. If thickness of a brake disk less admissible, replace a brake disk. Replacement of a brake disk is made also in the presence of cracks, zones of an overheat and other damages. |
| 4. Before installation of wheels check a condition of brake hoses and freedom of moving of brake hoses. Thus there should be no a contact to any sharp sides. |
