Control of a condition of brake disks
If for check of a condition of blocks wheels are removed, at the same time it is necessary to check and a condition of brake disks.

- On disks there should be no deep grooves (appeared as a result of influence of dirt or strongly worn-out blocks). Otherwise these grooves deeply врежутся in new brake shoes that will essentially reduce term of their service and, besides, will be lowered by brake influence.
- The brake disks damaged by furrows can be processed on the lathe, in case they not истончились as a result of long service life till the minimum size (look the table below).
- It is necessary to replace too thin disks in pairs.
- The bluish shade of brake disks has no value.
