Check of a condition of brake disks
If forward wheels act in film for carrying out check of brake slips, the condition of brake disks is at the same time checked also.
On disks there should not be deep grooves (because of dirt or the too strongly erased blocks). Grooves deeply run into new brake slips that considerably reduces term of their service and reduces brake effect.
The scratched brake disks can be ground on the lathe if they for long time of service were not erased yet till the admissible minimum size.
Too thin disks are replaced with pairs.
The bluish shade of a brake disk has no value.
