Expert Reply:
The problem you are having could be in how the brakes are wired. Basically you will have one power wire coming back from the trailer connector. Once it reaches the nearest axle the wire will tee off with one end going to the right side of the trailer and the other going to the left.
The wiring on each side will go to the nearest magnet. If there are 2 axles it will tee off a second time on each side with one wire going to the front magnet and one to the rear magnet on each side. I have included a picture that illustrates this.
Also make sure that the magnets are grounded to clean and corrosion free bare metal surfaces near the magnets.
If something such as the spindle is bend or if the brake mounting flange on the trouble side is not straight and concentric it can cause the drum to make contact with the brakes all the time and that would cause them to heat up. You may also need to adjust the trouble side differently to account for manufacturing tolerances.
