Brake Disc Measurement Sheet

Information

Notes on checking and measurement points can be found in:

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
- 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. → WM 4600TW TECHNICAL DATA/TEST VALUES AND BRAKE WEAR LIMITS
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) into 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.
