Test 1 (brake disc thickness)

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2005 Porsche 911, 2004 Porsche 911, 2003 Porsche 911, 2002 Porsche 911, and 2001 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

Measure the brake disc thickness -X- in the area of the outer or inner friction surface traces -arrows- , at 3 measuring points (each offset by 120 °) -A / B / C- . Refer to Fig 1 . To do this, use a suitable micrometer screw or a brake disc gauge (drawing shows a GT2 brake disc).
