I have a 6x10 carry on trailer. It doesnt have brakes should I have them installed. Do not carry heavy loads just mower etc etc. Im pulling it with a 98 F-150 4x4. i will be getting a 6x12 open trailer soon should I have brakes installed. Do some trailers 6x12 open come with brakes? Can they work through the electrical wiring connection. Give me some input will pulling loads with no brakes on trailer ruin my truck brakes??
