- Description of Tests 1-3, rear.
A copy or print-out of the data card shown here can be used to document the measured result. The data cards cannot be ordered.
- Make a copy or print-out of the data card shown here.
Information
- Actual values that are identical in all versions are already entered!
- 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.
