While driving the truck the brakes failed, pedal going to the floor. Took the truck to a repair shop and they stated that all the brake lines were rusted through, and more importantly, where the leaf springs attached to the underside of the car was completely rusted and the truck was unsafe to drive. The shop could not repair the car, and knew no one locally who could repair the car. There have been numerous rust issues with the truck over the years as follows: spare tire mounting rusted through and the spare tire flew off the truck in traffic; the fuel line had to be replaced twice due to rust; and the rear brakes rusted and had to be replaced three times.
About a year ago had one steel brake linbe bust because of rusted. Now today in my yard hit brake pedal right to floor again. Rusted brake line again. Have other brake lines rusted very bad.
