I have some doubts about the integrity of the brake wiring on our trailer.
Brakes seemed very poor - almost non existant. This last winter on a trip south to warmer climes, I did a little work on them. I replaced corroded ground connectors, and put on four new complete brake assemblies backing plates, shoes, and magnets.
When I went to solder the existing brake wires to the new magnets, I found that the copper was corroded black. I fanned out the individual wire strands and scraped them back to bright copper as best I could before re-twisting and soldering them - then covered them with weatherproof shrink tubes.
The brakes are much improved now - I can actually feel their effect!
I have also measured the current flow upon application and get about 15 amps which seems right, so I think my connections must be half decent.
I do still find however that the brakes are not as effective as they were on our previous "Award" 27 ft trailer that had pretty much the same set up.
On the last trailer, if I applied too much gain to get good braking at highway speeds, then the wheels would lock up at low speeds unless I backed off on the gain when slowing down to city street speeds - they certainly won't do that on our Airstream, I run at max gain all the time.
I suppose the difference could be due to the fact that the last trailer had a light wt of about 3500 lbs whereas the AS is 7400 though - maybe it is to be expected.
I did consider completely rewiring the brakes to ensure everything was as good as I could make it.
Since they are working half decently now after my recent work, I probably won't bother.
But what I had thought of doing because if the problem of the wiring running inside the belly pan, was to bypass the old wiring and run new HD wiring up to the front, clipped outside the belly pan, possibly in some type of plastic or metal conduit.
Seemed to me a lot easier, both in initial application and if I later had to work on it. I don't think there would be much of a downside.
