Brake Disc Measurement Sheet

Information 

• Actual values that are identical in all versions are already entered! 
• These values can change in the course of further development. Check if necessary and add the new values accordingly. →  4600TW TECHNICAL DATA/BRAKE WEAR LIMIT  . 

To document the measured result, a copy or printout of the data card illustrated can be used. The data cards cannot be ordered.

1. Make a copy or printout of the data card shown.

   Information 

   Notes on checking and measurement points can be found in:

   • → 4600TW TECHNICAL DATA/BRAKE WEAR LIMIT .
   • Test 1 = Brake disc thickness.  → 465002 CHECKING FRONT BRAKE DISCS (WEAR ASSESSMENT)  and → 465302 CHECKING REAR BRAKE DISCS (WEAR ASSESSMENT)  .
   • Test 2 = Lateral runout on brake disc and wheel hub.  → 465004 MEASURING FRONT BRAKE DISCS  and → 465304 MEASURING REAR BRAKE DISCS .
   • Test 3 = Thickness tolerance of brake disc. →  465004 MEASURING FRONT BRAKE DISCS   and →  465304 MEASURING REAR BRAKE DISCS  . 
2. 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.
3. Perform measurements (Test 1 to 3, actual status) and enter the values in the data card.
4. 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.
