Terrible factory splices in brake wiring

Yep those are bad doesn’t matter who did them. I was having issues with my 07 trailer after I bought it new. It never stopped good, not even ok! I went around and replaced all the poor crimp connections. I would t want a crimp connection on anything that moves or vibrates! I soldered all the connections. It helped a bit. My problem ultimately was bad magnets. Replaced all 4 and the trailer would stop both itself and the TV without a problem. I figure they were bad from the beginning. It couldn’t have been driven with the brakes applied because the shoes were good. I doubt the pin was pulled because they don’t install batteries until it’s sold.

Either way good job on repairing a potential accident.
