Adjusting Brake Push Rod (Adjusting Stop Light Switch): Notes

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.

The brake pedal has no stop. Since, when the brake pushrod is correctly set, the brake pedal has no support possibility in its original position, the permanently set free play in the brake unit is guaranteed. As a result, a pushrod play of approx. 1 mm is noticeable by manual actuation on the pedal plate of the brake pedal.

Adjusting the pushrod length changes the position of the brake pedal. To do this, undo the lock nut and turn the pushrod accordingly at the hexagon (arrow). See Fig 1 .

The brake pushrod is correctly set if the dimension X is 45 + 5 mm 

Perform measurement between the center of the brake pedal plate and the accelerator.
