Brake Disc Measurement Sheet

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!
- In the course of further development these values may change. If necessary, carry out a check and insert the new values accordingly. → WM 4600TW TECHNICAL DATA/BRAKE WEAR LIMIT
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.
Perform measurements (Test 1 to 3, 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.
