There are a few things that could be causing the problem you are having with your trailer brakes. First, you will want to check the adjustment to your brake assemblies. When turning the trailer wheel, you should be able to hear the brakes barely brushing all around as the wheel spins. If that is not the case you will want to adjust the brakes by accessing the adjustment gear on the back of the brakes (see video link). You will want to tighten up this gear until you cannot easily spin the trailer wheel. Then, you will want to back the gear off, usually about 10 clicks, but can vary for different brake setups.

After adjusting the trailer brakes, I would recommend re-adjusting your brake controller. You will want to unplug your brake controller for a few minutes to reset it and plug it back in. Then, drive and engage the trailer brakes with the manual over ride switch which will warm the brakes. Warming your trailer brakes will simulate conditions when the brakes are being used. Then you will follow the instructions on your brake controller for initial setup.

If the above recommendation does not work, it is possible that the brake magnets of the brake assemblies are worn and need to be replaced. You will want to inspect the brake magnets for windings. I have also linked an FAQ on testing your brake magnets.
