I have an 04 tb ext that I recently changed the passenger side upper ball joint in. Ever since then it feels like that brake is dragging and it's to the point that the pad is worn and now chewing into the rotor. Could this be a bad caliper that just happened to go bad around the same time? I'm going to change the pads and turn the rotors this weekend but am wondering if I should change the caliper also. Any suggestions?
