Yes, we got it figured out after trying out 4 different remanned calipers from NAPA. I broke down and bought a new caliper off Amazon. The hose ports on the remanned calipers were all slightly oval in shape, the flares inside the caliper were all slightly off center. All except one remanned caliper leaked brake fluid after the hoses were screwed in and seated properly.
The new caliper worked exactly like it should, flares and ports were spot on/perfect. I think the issue was that the ramanned calipers were so grossly out of spec that they were hanging up on the caliper slides causing them to lock up on the rotor. The new one didn't have any problems with it and functions flawlessly.
