Brake Hoses, Lines/piping, And Fittings problems of the 2004 GMC Sierra 1500

Corroded brake lines. This has been reported previously. I was driving down rural road getting ready to turn in my driveway when my brakes gave out. I I was lucky enough to be able to get it into the gravel driveway without killing someone. When I looked underneath to find the brake lines were corroded and one had burst. I had part of the line fixed with copper tubing. I am have since had 2 more lines burst. As well as a fuel line leak. This has become frustrating.

I purchased this vehicle brand new in 2004 and have taken very good care and almost 100,00 miles in almost 14 years however I applied the brake and all the brak fluid came out I had to drive over a person lawn to avoid hitting a person and a moving vehicle on 7/1/2017 due to rusty brake line and checking all lines were rusted . I am almost 75 years old and very concerned I was aware the lines were all rusted due to imported brake lines with inferior metals, never heard about and notice or recall. I almost injured a person and hit a car if I did not drive on someones lawn the vehivle was moving about 35 mph .

Brakes went out as I was pulling into my driveway, brake line corrosion.

Power train pcm defective with transfer case with bad designing with shoe pump, and brake line corroded and leak. Brake system will not prevent vehicle to stop when brake lines are leak. For my 2004 I was lucky driving on slow speed on city road, and I was able to use emergency brake to stop my truck.

On January 24, 2017 traveling on PA turnpike at posted speed limit of 70mph, when I applied brakes to slow when approaching slower vehicles. Brake pedal went to the floor and vehicle almost ran into the rear of slower vehicles. Metal brake line ruptured above left front wheel. When inspected, all brake lines exhibited extreme rust/corrosion to the point of flaking and thinning. This is an extreme safety issue which could have resulted in a major collision and would have injured or killed occupants. This problem is a major known safety defect and needs to be remedied by gm.

Driving vehicle, and lost brakes. Discovered the brake line had rusted thru causing loss of fluids. After researching this I found out this is a very common problem with certain year model gm vehicles. This is a extremley dangerous situation, and I cant believe there has not been a recall on this. Does it really take deaths for gm to act on defects they are aware of? I have a 1988 Jeep wrangler and the brake lines look a lot better than those on my truck. The sad thing is you cant even buy the break lines from the dealer because they dont sell them, would someone please look deeper into this before someone else gets killed or injured.

Entire brake line failure do to rusted brake lines.

While backing in driveway, brake pedal hit the floor with no pressure. Lost all fluid in system. 3 brake line to break in 4 years.

I was parking our 2004 GMC sierra pick up truck when my foot went right to the floor. After getting out of the truck, I noticed all the brake fluid draining out of the brake line on to the ground. When our mechanic looked at it, he said all the brake lines were rusted out and that the whole undercarriage of the truck was entirely rusted out. What a disgrace.

Got in my car and proceeded to go down the road I was doing about 45 miles an hour I hit the brakes to slow down and the brake pedal went the whole way to the floor after I got stopped and checked it out the brake lines are completely rusted through.

Incident #1 while traveling at 50 mph on a country road I applied brakes to decelerate for a 75 degree right hand bend in the road. The brake pedal went to the floor. I had to column shift down through third, second, and then to first gear, to slow down. I was unable to get to emergency brake. Fortunately it was on a lightly traveled road and there was no on coming traffic as I had to veer into that lane to make the turn. I was able to hobble home, with hazards on, by downshifting to slow down. The truck was towed to local repair shop. The rear brake lines had failed and were replaced. Incident #2 while traveling at 30 mph traveling down hill a raccoon ran across the road. I applied brakes in a defensive manner and the pedal went to the floor. I again had to column shift through third, second, and then hobble down hill in first gear. I was unable to engage emergency brake. I was able to hobble home down shifting through the gears. The truck was again to same shop and I had them replace all brake lines.

I was approaching a stop sign driving approximately 45 mph. When I applied the brakes the pedal went to the floor, and the vehicle wouldn't stop. I manuevered past several vehicles almost striking them. I was able to apply the emergency brake to stop the vehicle after some distance past the intersection. I am a police officer with 25 years on the job. I have attending various driving courses related to my profession. If a lay person was in this situation a serious accident would have happened. I barely escaped the accident due in part to training and a large amount of luck. On the day of the incident the vehicle had stopped normal at three prior intersections without giving any warning of a potential problem. I have read on line the theory about the salt causing the damage to the brake lines. I have never driven this vehicle in the snow since it is a spare vehicle. The vehicle has 72000 miles a large majority of those miles driven on the highway (summer and fall). I bought this vehicle new from the dealership in 2004. The cost to repair the brake lines was $1,100 dollars. A recall should be made in regards to this defect before someone is killed or seriously injured. I had a mechanic shop repair the vehicle since the dealership claimed they had no other reported failures on this vehicle. A quick look on various websites showed that to be a false claim. Anyone driving these types of vehicles please have your brake lines inspected by a mechanic.

While exiting the highway driver pressed brake pedal which sank all the way to the floor with approx 5 percent braking power. Driver lifted off and reapplied the brakes in an attempt to fix problem at this point a dash light and alarm illuminated to warn of brake issues; braking power was still only 5 percent. Driver was able to stop before an accident occurred but only because of light traffic and plenty of run off area. Upon inspection of vehicle it was evident that the brake lines had corroded and ruptured under the drivers door. Vehicle was taken to dealership where 6 brake lines were replaces due to corrosion. Vehicle was not driven in northern winters and has not been on any beaches.

The brake lines on my truck rotted off and it cost over a grand to fix them. There should be a recall.

While coming to an intersection the brakes were applied and the pedal became soft and when to the floor, without slowing the vehicle down. The transmission was shifted into neutral and the emergency/parking brake was applied immediately in order to stop the vehicle. The vehicle went to the local dealership where the diagnosis was a brake line had ruptured due to corrosion (rust) on the driver side rear line. The other three lines were in a similar state and had the potential to fail at any time. There was no indication on the message center that there was ever inadequate pressure to stop the vehicle with the hydraulic brake system even when it was steered to the side of the road and the brake pedal was applied to put the transmission into park.
