Notes on checking and measurement points can be found in:

Technical data relating to the tests.
Description of Test 1 = Brake disc thickness. → 465102 CHECKING FRONT PCCB BRAKE DISCS (WEAR ASSESSMENT USING TEST EQUIPMENT VAS 6813)
Description of Test 2 = Lateral runout and wheel hub. → 465004 MEASURING FRONT BRAKE DISCS

Information
- Nominal values that are identical in all versions are already entered!
- These values may change in the course of further development. Check them if necessary and add the new values as required.
Before taking measurements (Test 1 to Test 3), enter the general data, vehicle type and the missing nominal values (new brake disc thickness/brake disc wear limit) in the data card.
Carry out measurements (actual status) and enter the values in the data card.

If brake discs are to be replaced, carry out Test 2 with the new discs again and enter the latest values in a new data card.
