Notes on checking and measurement points can be found in:
- Technical data relating to the tests . → 4X00IN TECHNICAL DATA/BRAKE WEAR LIMIT
- Description of Test 1 = Brake disc thickness . → 465002 CHECKING FRONT BRAKE DISCS - WEAR ASSESSMENT
- Description of Test 2 = Lateral runout and wheel hub . → 465004 MEASURING FRONT BRAKE DISCS
- Description of Test 3 = Brake disc thickness tolerance . → 465004 MEASURING FRONT BRAKE DISCS
To document the measured result, a copy or print of the data card illustrated can be used. The data cards cannot be ordered.
- Make a copy or print of the data card shown.
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 measurement (Test 1 through 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 alignment 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 labor operation numbers.
Measure brake discs: 80 time units per axle.
