I was getting the fairly common electronic brake controller fault display at random on our way home from Florida. This is a 2022 F350. I tried cleaning the connections and put dielectric grease on them. Didn't help. It did not happen often (maybe 6 times). When it did happen I noticed that it would seem like there were no brakes on the trailer as I slowed down for a light or exit ramp, then they would suddenly catch and brake hard. Then it would be fine for a while before it happened again.
Started to do hub maintenance and check the brake pads this week. First one I pulled off I found a green wire inside the drum had somehow worn down the insulation to expose wire and it was laying against the spindle. It broke when I moved it so there weren't many strands holding it together. Spliced it up and all good so far; although I haven't driven it enough to confirm there isn't any other issue. But the other three looked fine.
