Adjusting The Switch If The Pedal Travel Is Too Large
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.
Press the pedal; press the plunger into the switch by one notch (audible click). This decreases the pedal travel to the operating point by approx. 3 ... 4 mm. Then recheck the adjustment.
