1 Other Fuel System problem

Failure Date: 02/22/2013

Front brake line failed. Completely rusted, it blew out inside one the clips that hold it in place. Horrible design. Truck is sitting in my driveway because I cannot afford to repair brakes. Estimate was over 1500, just to replace the lines, with coated steel, not stainless. Fuel lines are all rusted as well. All need replacement.

2 Other Fuel System problem

Failure Date: 09/12/2012

Backed out of driveway and brake pedal felt soft. Got to end of street and suspecting a problem began slowing early. Brake pedal went to the floor with very little pressure and very little stopping power. Went back to house and found a large puddle of brake fluid where the truck had been sitting. Opened the hood to look at brake reservoir and found it empty but also realized all hard brake lines in view were heavily corroded and crusted. Leak was from burst hard line below driver. All hard lines are heavily crusted and corroded near the point of failure if not already failed. Some fuel lines also corroded.
