Checking Clutch Free Play
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.
The clutch master cylinder has an inner stop. The push rod and the clutch pedal are always pressed against this stop by the clutch power spring. Due to the automatic hydraulic adjustment of the clutch, it is not possible to determine the clutch play by checking at the clutch pedal.
