I will second or third or fourth agree with checking or just plain redoing the wiring connections first.

Follow up:
After another quick check of things (adjustments, elec connections and voltage), along with finding 2 elec brake distributors to chat with, I am going with the magnets are just worn out. The wear hole indicators are either gone or barely visible. This trailer rolls 10k to 12k miles per year at 12k to 13k pounds, so I guess it is no surprise.
IMO, I highly doubt the brake assemblies are meant or expected to last that many miles. Realistically, unless you are a full timer, most TTs or 5ers probably do not see 30k miles in their life time.

1. If I was doing this, I would replace all 4 Drum assemblies at about $100 each. This gives you new BRAKE SHOES and Magnets and is very EASY to do. Also have a local shop turn the drums

2. The CORRECT test for the brakes is NOT using your brake Controller. If you suspect Magnets, I would apply 12 volts direct to the Brake Pin on the 7 way tow cord or just pull the break away and see if all 4 lock up. Doug

Look at the wires where they come out of the axles. It's a wear point the insulation on the wires get chaffed and cause a lot of issues. If that's the issue run a wire outside upper part of the axle, secure with zip ties.

Beat me to it...people talk about years and that works OK for typical use but your average RV may only get 2-5k miles per year. Miles will provide a better estimate of wear. Really it's brake use that wears them out, so non-freeway driving is the killer.

yep, highway miles is different that city miles.
I used to turn the brakes almost off in the city back when I had a cheapo controller. I just did not need the braking power to stop fast when speeds were low. On the highway I just never needed to do a lot of braking, so my brakes could go miles and miles.
Now that I have a high-end controller I leave it alone, it brakes softly when the truck does, and brakes harder when the truck does, less wear than a timed controller that brakes soft a second, then increases braking forces over a few seconds. Best $200 spent.

I would not replace the drums until they need replacing. $400 (4x100) might be pocket change for some, but most would rather not toss that money away needlessly, and I would never go disc on a regular trailer. Drums are fine for most sized trailers. DIsc are wonderful, but I cannot justify the expense when the drums are more than enough. Most tow vehicles do not need trailer brakes to begin with, which of course is of opinion. I still cringe to think dear old dad towing the family trailer with the station wagon equipped with 4 drum brakes, on the car, not the trailer, none on the trailer.

LOL. I think of that every time a discussion arises about tow vehicles. The old 72 Buick station wagon with 350 - 4 barrel had plenty of power to tow. My grandparent used one to tow a tt from Washington to Michigan and back.

Those old 3 speed transmissions did not have locking torque converters either.
