The wiring is no good. Probably corroded. Certainly not heavy enough.
Trailer companies tend to cheap out and put 14ga wire in for brakes. Sometimes they splurge on 12ga. Brakes really need 10ga wire.
Zip tie the brake wiring to the outside of the axles. Sleeve them in PVC or something but don't thread the wires inside the axles. What happens is the wires rub on the holes they pass through, and short out. They might rub on the PVC but even if they rub through PVC is non-conductive.
