LOL. The Z's parking brake is a simple cable and drum setup. When you set it, there may be a little shift of the car before it's really set and stable (you just feel a little roll and hear some rubbing as it takes a hold). If the force is OK and the brake holds the car, then it's normal. My post linked to above was because my parking brake didn't hold my car at all. It just needed a tension adjustment.
