Steve, you need to find the procedure for bleeding the brakes. Find the slot or hole you place your pry bar to pump the cylinder. Jack the trailer up and put on jack stands, get your son to help. While spinning a wheel have him pump it to make sure brake on each wheel is stopping and releasing properly. Check all the moving parts at coupler and master cylinder looking for excessive wear or loose parts. And your really checking to make sure brake is releasing after it stops and you release pressure on the master cylinder. If you guys haven't been into your system recently there should be no reason to have to bleed brakes. If bleeding brakes makes it better then problem comes back most likely you have a master cylinder leaking by internally. If you have to add much fluid to get performance back up you most likely have really worn brake shoes or pad's whichever you have.
