Greetings: I have a '98 Ranger 2wd with about 250K miles on it. I have a question related to a problem with the right rear wheel brake dragging. When you first drive the vehicle after being parked for awhile, there is no drag. After a mile or two, the right rear wheel brake has a light but noticeable drag. It's just the right rear wheel, and the drag causes the wheel and brake to heat up and have a slight burning odor. I recently replaced the brake shoes, brake hardware, wheel cylinders and drums on both rear wheels. I suspected that the right rear drum might be the culprit after measuring about 0.030" of radial runout, so I replaced that drum with a drum of better concentricity; no help. I disconnected and disabled the parking brake mechanism, in order to determine whether that was causing the issue; the drag remains even with the e-brake linkage disconnected. I have repeatedly verified visually that the self adjusters on both wheels are all the way "in" and that they don't drift outward during operation. The front brakes are OK. I have verified that the wheel bearings are spinning freely and quietly. Has anyone else seen this kind of issue with rear brake drag? Thanks very much.
