Rear breaks stuck after change

[nasdamus]

Hello! Last night I had a frozen left rear caliper, metal on metal stuck. Tonight I went ahead and threw it on the lift and redid both sides rear brakes - new pads, rotors and reman calipers. Got everything installed, bled both sides and everything was great. Put it into drive to test (pulled all tires) and all of a sudden the right rear wouldn't move, left would turn but could hear slight friction grinding. Pulled everything off right, reinstalled and then the problem switched to the left side. Had someone pump brakes and I can see the caliper is not frozen. The emergency brake is not engaged. Anyone have any ideas before I have this towed to a shop?

Quick update in case anyone comes across the same issue. I pulled the calipers back off and then put the original calipers back up. I was then getting a scraping sound from the passenger rear. The wheel wouldn't move on its own but I could drive on it, the brakes worked fine. Pulled the wheel back off and caliper. Manually turned wheel to identify scrap. It still made the noise with the caliper and pads off. Turns out the clip that came with the Wagner brake pads was too large and had metal tabs on both sides. The side closest to the rotor was hitting the rotor. Swapped out clip with one of the original ones and now am good to go.
