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