Disks with slightly bluish shade – absolutely normal phenomenon.
Pay attention to deep scratches on disks. They specify in the extraneous subjects clamped in overlays, the rough road dirt, the hardened or worn out overlays. At presence of "milling traces» depth to three millimetres still it is possible not to be anxious. However in any case release overlays and remove already crushed extraneous subjects.
Measure a thickness of a disk is better by means of a calliper and two coins of euro. Put from both parties of a disk on one coin between a calliper and a disk. Naturally, it is necessary to subtract a thickness of these two coins from the received value.
It is necessary to hand over the disks "peeled" to is minimum possible thickness in scrap metal. The scratched disks can be ground, however. Thus replace and process disks always in pairs.

Reading and subtraction: for reception of correct value it is necessary to subtract a thickness of both coins after measurement. |
