Rendezvous Parking Brake

Have a 2004 Buick Rendezvous that after changing the brake pads all the way around have a parking brake issue. The braking from the disk brakes is great with the new pads but the parking brake which is a separate drum brake system is not working correctly. The parking brake lever almost bottems out before engaging and is not engaging to the full capicity it was before. I did not mess with the parking brake pads and cannot find any information about adjusting them. I have found a few complaints about this problem but short of "took it to the dealer for an expensive adjustment" haven't found out how to adjust it myself.

Any help out there from you Rendezvous experts?
