Information
- Actual 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. → 4650TW TECHNICAL DATA/BRAKE WEAR LIMIT
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.

Measuring prerequisites

Note the labor operation numbers.
Measuring brake discs: 80 time units per axle.
