This RV belongs to my kids. An on the road check was sone to be sure it was not locked up, and the controller was backed way down. The shop repair and inspection were done only a couple miles from home. Just to be clear, I am more than familiar with electric brakes in all respects — repair, replace and adjust. The shop verdict is that the offending brake was seriously over adjusted. Yet, there had been no problem for 1500 miles, and the factory insists it was adjusted when new.. It appeared suddenly. Now everything is properly adjusted and it has been inspected. So the question is this: what would cause a non-self adjusting brake to suddenly become over adjusted? Dexter says it can't unless there is a brake "malfunction'". But they can't even suggest what that might be. Bad magnet? Intermittent short? These wheels and tires are on an in-cab monitor, so the temps will show if the problem returns. Its originally showed a slightly higher temp (5 or 6 degrees) but nothing dramatic. A passing motorist warned that the brake was smoking.
