Hey brake needs to be set at .002. Use a brake tool. If u don't the brake will sag a little on inspection. Also it sounds like your brake is not centered in the hole. This will still allow it to pick but will cause it to drop at a angle of the drum. Also if u have the KDL drive on it and the car drifts up only on the top floor, after it parks I have a fix for that. But PM me if that's the case.
