I would start by examining your trailer brakes. If the shoes or springs are very worn, and are out of adjustment, they could be causing the brake assembly to hang up, or stick. You can use a circuit tester, like part # PTW2993, on the blue wire exiting the rear of the brake controller, and check for voltage when the brake override switch is activated. If the voltage disappears immediately once the switch is released, you'll know that it is the brakes hanging up, and not the brake controller malfunctioning.
