Trailer was fine and backed it into my driveway. Now that it is time to get the boat out, the brakes are locked. Trailer will roll freely in reverse, but locked in forward. Friend said to flip plug and that would release brakes, but that did not work. Had trailer for a year and this was never an issue. Help, I need to get my boat winterized!!!!!!!!!!!!
Here are some pics I took. Plug has always been missing 4th prong without issue as you will see in pic.
