Parking Brake - Poor Release - Repair Procedure
Remove and destroy Bulletin 206-01, dated 4/97. Replace with this Bulletin.
Updated information is shown by black bars and asterisks.
Issue:
Some XK8 vehicles within the above VIN Range, may experience either a parking brake (handbrake) warning lamp that remains ON, and/or a rattle noise from rear of vehicle on uneven road surfaces.
Readjustment of the parking brake mechanism will provide a more positive return to the hand brake lever, ensuring that the warning lamp does not remain on. Removing the slack from the cable will eliminate the rattle which may be caused by the hand brake equalizer.
A secondary return spring and support bracket were introduced at VIN 009014. This bulletin includes instructions for installing these components.
Action:
In case of a customer complaint of the above conditions on a 1997 MY XK8 within the above VIN range proceed as follows:
