Well, I got a chance to remove the hubs today and found all sorts of issues. First off, the wiring looked like my 9 year old son wired it and when I started stripping the wires that go to the magnet, they are black. When I cut into the wires, I see very little to no copper. The wires are like this up to the magnet and the magnet looks like it has chew marks on the front end. From the look of the pads and drums, it seems the brakes and magnet have not been in contact with the drum for some time. It looks like the best option is 4 new brake assemblies complete with pads and magnet for me. The bearings and drum seem to be in decent shape. I am going to a local trailer shop to confirm, but I think I found my problem (Hopefuly, hehehe). Knowing my luck, I will replace these and have the same problem. I will post once I replace. Thanks to all.
