Atcbrownie, I didn't see where anyone confirmed your suspicion on the loose brake wire, but yes, that is what most likely wore your brake out and not necessarily an adjustment issue. It received more power at each braking and caused the eventual fail.
I highly doubt this is the problem. All brake magnets are fed in parallel. If one was not connected, the other 3 would still pull their same currents at whatever voltage the brake controller was sending. Even if it was possible, then the other 3 would all look like this one. Unless the wire somehow ENERGIZED the single brake all the time (doubtful if it was "loose"), I don't see this as the problem.
OK, I just noticed the video above. I watched it, but I don't understand what the guy is trying to explain. How do I adjust with the wheel and hub in place?
If I just leave them alone are they going to eventually adjust themselves to the correct position, no matter how far off they are right now?
You must adjust them "Manually" you will not have "much/any" stopping power until the shoe's are "Burnished/Seated" to the drum ark! This is ALL explained in "Full Detail" in Dexters Brake Manual! Youroo!!
On our recent KY to FL trip I noticed reduced braking as we were nearing
Ft Myers. Once in the camp ground I tossed a patio mat under the trailer and
rolled under there to have a look.
I found the brake wires for one axle hanging loose.
It appeared the wires were short from the factory and somewhere along
the interstate I'd hit a dip or something and the axle went down and
pulled off the connectors from the short pigtails.
Luckily I had extra wire and wire nuts that I used to extend and re-connect
the dead axle. Had to adjust the controller back down once we rolled out
I had noticed short wires during my new trailer inspection but forgot to
follow up. Luckily we didn't loose both axle brakes and didn't have any panic
stops along the way!
