I almost ran into another car because the other driver stopped suddenly and I had to pump the brakes over and over to stop when the rusted line broke. I was on a city street driving speed limit and was lucky to be able to stop. I was towing my trailer last week and almost lost the trailer because the entire underbody is rusted. I have had several trucks and never have seen this happen. It was a scary situation in both cases.
