Since, all the other wheels on the trailer seem to be in proper working order, we can assume that the brake controller is working correctly.

Sounds like you might have a brake assembly that is out of adjustment. Using a Brake Adjustment Spoon # W80630, or a flat head screwdriver, you can adjust the star wheel that can be accessed at the back of the brake backing plate. At the 3:00 minute make of the attached video, our technician will explain how to adjust the trailer brakes.

If the problem is not fixed by adjustment, then you may have an issue of a damage brake component or worn magnet that may need to be replaced.

I also attached an article that explains how to test the brake magnet for defect for you to review.
