Gets Brakes Checked
Often on vehicles with front disks and rear drums, the rear drums get out of adjustment and it is difficult to know as the front disks do most of the stopping. This is particularly true on a truck that is driven predominantly empty. You may have needed the rear brakes and they were simply not there. As for the brakes on the trailer activate the surge brake and check to see if the wheel will spin. When I am alone without help or may as well be without help I use a ratcheting tie down to pull the surge brake back. If you are without the mechanical aptitude go get your brakes checked. Many places do it for free. I know that Sears and Midas do. When your brakes get that hot it can boil the brake fluid and render the brakes useless not a situation I would want to be in, especially with #6000 worth of boat, trailer, beer, and all of the other paraphernalia that go onto the boat behind me.
