Maybe the drum brakes on your trailers need to be adjusted. One way to check is get a trailer plug tester or test light and stick in in your plug then hit the brake. If the Brake light on it lights up brightly it's getting it's 12+ volts and it's not your truck. If it's dim and it's turned all the way up it's your truck. It's more than likely that the star wheel adjusters inside (circa 1970's Chevy Pickup & yes your dealing with drum brakes here) are frozen with rust and grime. The other thing that could be happening is the magnets are trashed or the drums which is the thick metal that activates the magnets are scored badly. This scoring would not be where the brake pads contact the drum but rather the area that the magnet is activated by. Basically I'd advise you guys to go get your trailer brakes checked out unless you want to play with yourself. They sell complete brake kits and drums for cheap that unbolt at the backing plate. There is no worry of mixing the two wires. The power comes in one side and puts it through the magnet to ground.

I hope this helps some of you. Please fix your trailer so that you do not have a brake failure.
