Brake Disc Measurement Sheet

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2012 Porsche Cayman, 2012 Porsche Boxster, 2011 Porsche Cayman, 2011 Porsche Boxster, and 2010 Porsche Cayman. However, it is still accessible from the selected car via links, so may be relevant.

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.
