The slides are frozen. Not an uncommon problem on that body style vehicle.
The caliber is frozen in one position and the piston is only applying the inboard pad.
I would replace the calipers.
Side Note..there was a GM technical bulletin on this complaint with a set of special tools to remove the slides and hone the bore, but after 14 years it is doubtful that any GM dealers still have the complete set of tools to perform the repair
