I inherited this used single wheeled double axle goose neck trailer. It has been abused in its'life. It has hauled way past its' weight rating in the past. I would like to fix it to use it but I am concerned about the condition of it. I am concerned about the structural integrity of it. I don't want to haul something to have the trailer break at a weld or something and collapse. How could I tell if the trailer is solid and not going to break? Also, the brakes have not worked in a while. Should I get new brakes or try to get these working? I want them to be reliable. Also, would these brakes be asbestos? The trailer was made in the mid 1990s. Thank You all for the help.
