First thing to try is to blow out both connections- on the truck and on the trailer. Unless you have caps for them they get all kinds of gunk in there over the winter that can cause short circuits. Chris

This is a dual axle trailer with electric brakes that hasn't been used for months (winter) and now is not 100%. One brake is locking up at the slightest touch of the brake pedal that actuates the brake lights. Could this be a wiring fault? Or could some object be embedded in the brake pad? Or?
