Working on a family members ford fusion. I replaced the rear pads and rotors. The one rear rotor was pretty worn out. 2 weeks later I notice that the rotor is wearing out pretty bad in one spot. So I took the wheel off today to take a look. And it seems like the pads are making constant contact with the rotor. And with the brakes applied or not, they squeal. So is it a bad caliper? I put lube on the floating pins. Or is it the e-brake that is stuck? The other side is fine and doesnt have a problem. Here are some pics
