Brake Hoses, Lines/piping, And Fittings problems of the 2004 GMC Sierra 2500

Pulling out of a parking lot, lost brakes. Steel brake lines by fuel tank, let go causing truck to loose brakes.

I was traveling south on I-75 highway about 70 mph, in motion, in northern michigan and had to stop fast when an accident occurred in front of me. I slammed/mashed my foot on the brake pedal only to feel it fall to the floor, the metal hydraulic line failed and I now have no brakes at all!! I began to press on the parking brake and down shift the transmission to assist in the slowing of the vehicle. I also steered around the stopped cars into the side and ditch of the road. I luckily had the right reactions but not all people do or cannot act as fast. This is a dangerous issue with this GMC sierra 2004. Please have it recalled. I had to have the repair shop replace all the metal brake lines as they were corroded. I have never had a vehicle fail its brake lines like this. My vehicle only has 48,000 miles on it and is garage kept super clean.

The contact owns a 2004 GMC Sierra 2500 hd. While driving 10 mph, the brakes failed without warning. It was diagnosed that all the brake lines needed to be replaced. The manufacturer was made aware of the failure. The approximate failure mileage was 176,395.

I live in south east MA. Were sault is use always and it has rotted my brake lines at the abs controll a line let go on my truck with family and my grand babies I am a heavy truck operator with a cdl so I know not to panic I got my truck stopped without a crash but if my wife was driveing or my young daughter they wouldnt be so lucky we in the saulting states should have staneless steal for safty cant be to much to ask for young lifes at stake or people who panic what should I do at the time I was in the city of taunton I was coming to a heavily traveled street in rush hour trafic the brake line to rear brakes falled because of rot on inspion I see they are all rotting and need to be repaired I dont have body rot or frame rot of any kind always car wash after storms on nice days.

I was leaving a parking lot, and as I hit my brakes, there were no brakes. I limped home, using the e-brake and transmission to keep the truck under control. Upon inspection I found the front brake line rusted and leaking.

This seldom used, well maintained, garaged truck, blew out the brake lines on left side on the frame, under the door, resulting in total brake failure. I had to use the parking brake to stop the vehicle. I was on my way to pick up a #9000 boat. If I had that boat behind the truck, it could have killed me, or others on the road. Brake lines are not a normal service part. Replacing all the brake lines is costing me 1300, at a minimum. My neighbor next door has a similar 2004 GMC sierra, with about the same mileage, only his is a 1/2 ton, where mine is 3/4 ton. His truck had the same failure the week before, in the exact same location on the lines. Do a simple search looking for brake failures on these vehicles, and you find that its well documented. This should be a recall before people are killed. There is no way that I should be looking at brake line failure on a 10 year old garaged truck that has a tow capacity of over 10,000 #'s. How should someone detect the integrity of the brake lines to determine when the should be replaced?.

On 9-19-2014 the truck was stopped at a red light and started to inch forward. Slight pressure on the brake pedal stopped the movement. The event was so quick and slight I thought nothing about it. I turned on the freeway and drove 30 or 40 miles before touching the brake pedal again. When I did it went almost to the floor without slowing the truck speed any appreciable amount. At that point I knew I had a serious problem. I geared the truck down and was able to avoid being involved in an accident. If I had needed to come to a full and fast stop it could easily have been a disaster. An internet search revealed gm has had this problem for some time without notice to truck owners that it exists. An inspection of the brake lines was done and indicated a failure in the brake line system due to rust. The fuel lines showed the same kind of deterioration. Pictures can be provided to verify the lack of advanced rust conditions to the underneath of the truck other than the brake line system, the fuel line system, and the drive shaft. The truck was purchased new in south carolina and has been driven there 90% on the total mileage on it.

Brake lines rusted and leaking.

The complaint is that the brake lines failed and are made of very poor material. The brake line failed on my way to work one day on March 10,2015.

The contact owns a 2004 GMC Sierra 2500. The contact stated that the brake failed to engage while attempting to apply the brake pedal while driving 35 mph. The vehicle was towed to a local mechanic for inspection that confirmed that the brake lines were corroded. The vehicle was not repaired. The VIN was not available. The manufacturer was not made aware of the failure. The failure and current mileage was 98,000.

When attempting to stop, the truck began to stop and then all of a sudden the brake pedal went to the floor. At this point there were no brakes at all. Thankfully no one was in front of me so I was able to coast until the vehicle slowed, and then use the e-brake to slow down enough to turn. Upon further inspection, a brake line had broken.

While traveling on the PA turnpike at approx. 60 mph, traffic suddenly slowed in front of me. I was pulling our 30 fifth wheel camper at the time. I applied the brake hard had a split second of braking action and then the brake pedal went to the floor. I was able to use the manual trailer brake control to slow the truck some, swerved into the left lane missing the car in front of me by inches and the car to the left of me swerved into the far left lane to avoid hitting me. (three lane highway) I managed to drive the truck to a rest area about a mile down the road using both the trailer brakes and the truck emergency brakes. The cause of the brake failure was that the brake line located under the drivers area had rusted through and ruptured.

The contact owns a 2004 GMC Sierra 2500 hd. The contact stated that while driving 40 mph, he applied the brakes but the vehicle did not respond. He continued applying pressure until the pedal touched the floorboard and finally, the vehicle came to a stop. The vehicle was taken to a dealer for diagnosis and the contact was informed that the steel brake lines exhibited massive corrosion and were leaking. The vehicle was taken to a different dealer where the repair was completed. The manufacturer was notified of the failure. The failure and current mileage was 80,000.

My brake lines rusted at the rear of the lt front wheel splash area. This vehicle has low miles for the year and was not driven in salt or deice. The brake line should not need to be replaced at this time with so much service life left. I was lucky, the brake line burst in my driveway.

Rusty brake lines on 2004 GMC 2500hd sierra. Almost caused me to have an accident because the brake petal went to the floor immediately when the brake line burst. I have pictures of the old rusted brake lines if you would like to see the pictures. Since it seems to be a wide spread problem on gm pickup trucks from researching it on the internet, I'm curious to know when they are going to recall them? just saw on the news where there is a government recall on 2005-2009 Subaru's for the same problem. It cost $1290. 00 to repair all the brake lines.

Complete brake failure, when brake line blew out while trying to stop. Prior to hitting car in front, swerved into left turn lane and applied emergency brake.

I was approaching a one lane covered bridge on the way home from work and another approaching vehicle failed to yield. I made an emergency stop by pressing firmly on the brakes. Brake pedal went right to the floor. I had to quickly use my foot operated emergency/parking brake to stop from having a head on collision. I had to pay close to $1200 to have the entire brake line system replaced due to severe rust of the brake lines. I am very fortunate that this turned out the way it did. My life and the lives of others are being endangered by gm not using a material that is resistant to corrosion.

Brake lines all rotted away near abs module mounted in frame. I had to take to a shop to get all line replace from abs module forward. This truck has never been near salt ever. 100,000 miles and already relining the truck! fuel lines look like they only have a few months left. This is a danger and a huge waste of money for a buyer I have had other gm cars that are 30 years old with 350,000 miles with factory brake and fuel lines.

Leaving small rural road. Brake pedal went to floor and vehicle rolled through stop sign. No oncoming traffic. Upon inspection, left forward brake line had ruptured due to corrosion. Only matter of time before other brake lines will fail.

The contact owns a 2004 GMC Sierra 2500 hd. The contact stated that while driving 25 mph downhill, the driver was attempting to brake and the pedal depressed to the floor. The contact mentioned that the failure occurred twice before. The vehicle was taken to the dealer, who diagnosed that the brake lines were completely corroded. The manufacturer was made aware of the failure and did not offer any assistance. The vehicle was not repaired. The failure mileage was 33,000 and the current mileage was 36,000.

Both front hydraulic brake lines corroded on drivers side, with loss of braking, on chassis top rear of front wheel. It appears that there is a large wiring loom (1 1/2" o. D. ) clipped on top of hydraulic lines, one to lf and rf wheels. Corrosion on both lines are at the contact of the loom and lines. Vibration may have caused the loom and lines to rub and allowed moisture to corrode the brake lines.

The contact owns a 2004 GMC Sierra 2500 hd. The contact stated that while driving approximately 50 mph and attempting to decelerate, the brake pedal went straight to the floorboard abnormally. The vehicle was taken to a dealer where they advised him that the driver side rear steel brake line had failed. They advised him that all brake lines needed to be replaced due to the severity of the corrosion. The vehicle was not repaired. The manufacturer was contacted and they offered no assistance. The failure and the current mileages were approximately 38,400.

Brake lines are rotted out. I pushed on my brake pedal while comming to a red light and it went to the floor, the rusted lines had broken and my brakes did not work. Luckely I was not going to fast or to close to the car in front of me so I was able to slow enough to turn off the road by pushing in my parking brake.

The contact owns a 2004 GMC Sierra 2500 hd. The contact was driving 25 mph and applied the brakes for a traffic stop when there was a pulsation coming from the brakes. This caused the brakes to be depressed abnormally into the floorboard. The contact could not stop the vehicle until he engaged the emergency brakes. The vehicle was driven to the dealer and after inspection, the dealer informed him that the brake line was rusted and had ruptured. In addition, the dealer advised that there were no recalls for the failure. The manufacturer was contacted who advised that a representative would later return his call. The vehicle was not repaired. The failure mileage was 42,000.

The contact owns a 2004 GMC Sierra 2500. While the contact attempted to move the vehicle, the brakes failed. He inspected the vehicle and found a leak, and noticed that the brake lines were corroded and leaking brake fluid. The vehicle was towed to the dealership who stated that the main brake lines were also corroded. The vehicle was repaired. The manufacturer will be contacted. The failure and current mileages were 50,000. Updated 03/16/jb.

I was approaching an intersection in my 2004 GMC sierra 4x4 2500hd pickup truck with a 2800 pound trailer when I pressed the brakes to stop. The brake pedal went to the floor and I was unable to stop. The trailer brakes were not enough to stop the vehicle and I continued into the intersection and was almost struck by two other vehicles. They just missed hitting my vehicle and causing serious injuries to myself and my passenger, as well as themselves. When I opened the hood there was brake fluid all over the drivers side of the engine compartment. I had the vehicle towed to the nearest GMC dealer. The dealer told me that a brake line had burst and needed to be replaced. He also stated that all the brake lines were corroded and needed to be replaced at $750. 00 per side. He told me that this was a common problem for these vehicles and that these lines only last 4-7 years on average. There is also significant corrosion on the frame. My vehicle is always garaged and regular maintenance is done. The dealer then told me that since we live in a snow belt state that I should expect this and that GMC will not help with the repair. I told him that I am very upset and that I have been a firefighter/paramedic for over 25 years, and if what he just said was true, then I would have had to rescue an awful lot of people from their crashed vehicles if on average brake lines only lasted 4-7 years. I feel that this needs to be reported and investigated because it is a very serious safety issue and people are going to get hurt if what the dealer told me is true. I would appreciate it if you would look into this matter. At this point my vehicle is sitting at the dealership in an unrepaired condition until further action by either GMC or NHTSA happens.

1. Applied brakes when leaving driveway. 2. Brakes failed completely. 3. Brake lines completely rusted out. Right front failed allowing brake fluid and requisite pressure to escape. I replaced the failed section.
