Brake Disc Measurement Sheet

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2013 Porsche 911, 2012 Porsche 911, 2011 Porsche 911, 2010 Porsche 911, and 2009 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

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.

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 .
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.
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.
