Check of a condition of brake disks
If forward wheels are removed for conducting check of brake slips, then also the condition of brake disks is at the same time checked.
On disks there should not be deep grooves (because of dirt or too strongly erased blocks). Grooves deeply crash into new brake slips that considerably reduces the 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 to the admissible minimum size yet.
Too thin disks are replaced with couples.
The bluish shade of a brake disk does not matter.
