if visual survey is complicated, remove wheels;
measure thickness of external brake shoes together with the metal basis of a block. Thickness of internal brake shoes define visually;
brake shoes of lobbies and back disk brakes reach a wear limit if their thickness makes 7 mm together with the metal basis of a block. In this case all brake shoes on one axis are subject to replacement.

       NOTE
Under the most adverse service conditions of the car wear of brake slips makes no more than 1 mm on 1000 km of run of the car. At normal operation of the car the resource of work of brake shoes makes not less than 30 000 km of run of the car.
