Parking Brake Pedal Assembly Modified

Modified Pedal Assembly 

Phased in as of approximately 09/2002 a modified design of parking brake pedal systems have been fitted. See Figure.

The new version of the pedal assembly has a pulled notch instead of a pushed notch, as previously.

This results in different values for the adjustment of the parking brake.

On account of the successive production launch and the possibility that in the case of repair, that old replaces new or new replaces old, on each vehicle, the version of the pedal assembly is determined before the parking brake is adjusted.

The new and previous version can be distinguished by the position of the shaft journal (3) in the pedal lever (4). Moreover the notches (2a, 2b) differ in color. See Fig 1.

1. Late Type
   
   The shaft journal (3) of detent (2a) is mounted offset from the pedal lever center. Color of notch(2a) is light gray. See Fig 1.
2. Previous Version
   
   The shaft journal (3) of the notch (2b) is mounted centrally in the pedal lever (4). Color of notch (2b) is black. See Fig 1.
