Had transmission problems, put the car in the shop to have the rebuild done. Before I put it in, I was trying to troubleshoot the issues. Seemed like I had a stuck caliper on passenger front. The wheel would not move easily, in neutral, by hand. Seemed to be freezing. So I bought a new caliper, new brake hose. Brake pads were still good, I changed them out just a few months ago, replaced the rotors at the same time. Got the new caliper on there, and it seems to be doing the same thing, only now there's an intermittent grinding/scraping when I take off. At high speeds it's either not happening, or happening so fast it's not noticeable. Braking doesn't seem to change it, it's not a constant squeal like the fingers. It's almost like the rotor is warped, and it's rubbing on one side of the spin. Transmission shop says it looks like the caliper is rubbing on the side of edge of the rotor, not on the sides where the brake pads are, but the lip edge. They think maybe I got the wrong caliper. I checked the receipt, and the part numbers matched with the site, and there doesn't seem to be any difference between models, such as different calipers, they all show the same. I thought maybe the metal line between the master cylinder and the rubber brake hose to the caliper might be bad or something. I'm not having any issues with any other side, and it wasn't grinding like this before I put the new one on. Still seems to stick though, I can turn it by hand, but not like I can on the drivers side.

Ideas?
