I think you answered your own question Rescuer, it's likely the PO did put the pads on but that's not the whole job. I think you really need to take the calipers apart, clean them up, clean the pistons of all the crud that's probably on them and reassemble the lot with new seals and dust covers. At that time you can remove the caliper sleeve and make sure it's clean and well greased. Repair kits for the brakes come with the seals and the rubber boots for the ends of the mounting sleeve.
As I mentioned before take a close look at the brake caliper bracket where it goes over the brake disk. The slot should be centered over the disk. If it is and your brake binds it's because the PO replaced the thin pad on one side with a thicker one. If the caliper had frozen in position with a thinner pad, it can't move to allow for the thicker new pad resulting in a lot of drag and wear. If the caliper is properly free to move side to side as it's supposed to the pads will wear pretty evenly.
Just gotta bite the bullet, there's a long summer coming with lots of riding. Don't take a chance with the brakes, they're more important than the engine toward keeping you and your bike alive and healthy!
