I should of said start checking the ground side. Likely at your trailer age, they use the frame for the ground path, often just a self tapping screw. Pull the screw, clean paint/rust from around
and in hole. Clean all corrosion off terminal. (Replace?) Once all is clean and tight, all is working, spray paint the area to slow return.
BTW, if the breaks grounds to axle, don't mess with it, run wire at least to frame.

I have checked everything visible and I can't see anything that looks like it would be a problem. I have heard of insulation wearing off inside the axles over time. It might not be my problem but I think that I will pull new wires thru and then I will know.
Replacing the wiring will give you peace of mind that the wires are are good and you'll need to replace all the connections for the new wires so in the end your problem will be fixed.
safe travels.
Just like telling who is tourist, just looking at connections, your eyes can lie to you.
As for insulation wearing off; First, the only way missing insulation will stop electricity from going where you want it is the electricity finds another way back to battery. (Short cut, or short) A short that would carry enough currant to keep brakes would blow fuse/breaker (if somebody was silly enough to use in brake circuit) or burn the wires.
Also, wire inside the tube will not rub enough to cause problems, except where it goes thru the tube.
Now I'm going to poop in some people's oatmeal. First, I need to give some info so you can decide if I'm trumping around, or have a idea what I'm doing.
I have built trailers, bought and rebuilt wrecked trailers. 1, that cutting and welding burned most of wiring out of has been pulled probably 2 million miles over 20 years after I rebuilt it.
And for about 10 years winter time when construction hauling was slow I put my phone number out at scale to do repairs for the guys that had to get there snot fixed and down the road. Trailer light issues made more than a few house payments. Now you can see not much of this is strictly RV, but do the electrons know they are going on vacation instead of to work?
Now a question for the OP, and anybody else that has a electrical problem that is hard to find. You know your tool and skill set. Are you right sure that when you run that new wire, can you route it, protect it and make the connections well enough to say there will be no more problems?
Some of my biggest bills was when somebody has "just run another wire" to solve a problem and didn't do a good job. Most times the old wires are not removed, so more places for trouble. Plus it is hard to run wire, because wires or other things are blocking the safe path of old wires. 99% of the problems are easy to fix, once you find them.
It is my opinion, based on what I have seen, if you lack the ability to find your problem you are not qualified to run new wires.
