2. The assessment of a condition of brake shoes can be made by a way of their visual survey through the special window provided in the case of a support. The standard thickness of slips makes 10 mm, minimum admissible - 2.0 mm. |
3. Replacement of worn-out brake shoes should be made at the same time on both brake mechanisms of one axis of the car.
4. If non-uniform wear of blocks takes place, it is necessary to check freedom of moving of the piston in the cylinder of the corresponding support. |
