Brake Hoses, Lines/piping, And Fittings problems of the 2004 Chevrolet Silverado 3500

Front brake lines failed causing fluid loss and complete loss of brakes. Happened at slow speed, but still was unable to stop before hitting a fixed object.

2 problems: 1- while driving with no warning the brakes failed. After coasting to a stop I noticed a brake line had ruptured at the frame rail under driver area. I was able to crimp brake line with a pair of vice grip pliers and move truck to a safe location for repair. I believe the brake lines used on these trucks to be of such inferior quality that sudden failure is a common occurrence. 2- my truck has dual tanks for diesel fuel and they have worked sporadically for years. I did not see this as a safety issue as much as an inconvenience. However while my truck was idling on a hot summer day I noticed diesel fuel dripping out of the front tank filler cap. Apparently the pump that pumps the fuel from the rear tank to the front tank was receiving a signal to pump even though the front tank was completely filled. It was continuing to pump and leaking the fuel out the filler neck. This seems like a serious safety hazard to me. I do not know if the root of the problem is the float that sticks in the rear tank, the sending units that fail, a wiring ground issue or some other electronic glitch. I do know issues with dual tank duramax diesel trucks are about as common as the truck itself is. After researching online I realized many other owners of my vehicle model have had both of the exact same problems so I thought I should report them.

I was coming home from work this evening and was pulling up to the garage and the brakes failed causing me to hit the garage. I was traveling less than 5 mph. The brake pedal went all the way to the floor and the vehicle would not stop. After getting out of the vehicle found brake fluid all over the driveway. Brake lines was found to be rusted in two in several places after having a friend who is a mechanic come and look at vehicle. He found a couple lines that had exploded thru right under the drivers side seat on top the frame and another one above the fuel tank. After googling what had happened there thousands of complaints with NHTSA on this problem with gm vehicles. Why are we paying you people to try and keep the public safe. This is a very ongoing problem with gm vehicles and needs addressed promtly.

While driving my chevy Silverado 3500 dually at approximately 50 mph, I had so make a sudden emergency stop. My brake pedal went to the floor with virtually no stopping power for the vehicle. I swerved out of the way to avoid an accident and was very lucky. The truck went directly to the repair shop which has informed me that the brake lines are rusted through and all need to be changed. I called the chevy support number to report this problem and ask about a recall. The rep took the last eight of my VIN number and said there is no known problem with the brakes on this vehicle. I tow heavy equipment with this truck for work, so it is an alarming safety concern for me for the brakes to suddenly not work without warning. I am lucky that nobody got killed due to this problem.

Brake line rusted and failed while driving. Heavy rust on several brake lines, frame, and cross members.

Brake lines rusted through casing brake failure and a crash. No warning light.

Brake lines, transmission lines and engine coolant lines all failing on 2004 chevy Silverado 3500 hd as well as on 2003 GMC sierra 2500 hd. These problems have caused numerous amounts of time to repair and replafe, and today there was a brake failuer on the 2004 hd GMC that almost resulted in deadly accident. These lines should not have rusted and we have issues with both vehicles on the same lines. These vehicles were producted with inadequate parts for all lines on the underside of vehicle. There should not be 1,000 plus complaints from consumers regarding the rusting of these components, of which have cuased several major anmd life safety issues. The brake lines are an integral part of any vehicle and to have them rust thru to the degree of all the complaints there is obviously an issue with the compenents the manufacturer installed on these vehicles. Between our 2004 chevy and 2003 GMC trucks we have replaced all of the tranmission collant lines, oil engine lines and ready to change brake lines in 1 truck with the other truck having to also be replaced due to rust. The entire underside compenents are completely rusted through.
