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