There are different magnets for different size brakes. I don't know if they will interchange, but this is interesting: https://www.etrailer.com/question-8117.html
One common cause is too small wire, wired first to one magnet, then the next, then the next... The first one in line gets the most voltage, not a lot of difference, but can be enough to cause problems. Best method is to wire down the middle, tee off to each wheel, try to keep the leads the same length, use #12 wire. Soldering the connections is best, heat shrink and liquid tape make a good water proofing. If there are any of the little blue fold over connectors, they need to be removed, horrible way to wire anything, especially something subject to water and shock vibration!
As with any brake system, a little bit of grease can cause a lot of problems. Any leaking grease seals need to be fixed and the grease cleaned or shoes replaced. Another factor is suspension geometry, or differentials in weight on a particular axle or wheel. Be sure the trailer is riding level, all the spring linkage is in order and moving freely.
As with any brake, a tiny amount of grease will create big problems. If there is any seal leakage it needs to be corrected, cleaned up, or shoes replaced.
