2006 GMC Sierra brakes problems

Filed Dec 26, 2015 · Brakes · 81,750 miles · OH

Total brake failure while in motion. Corroded brake line ruptured causing immediate loss of all fluid. Had this happened 5 minutes earlier, I would have been on a four lane highway in bumper to bumper christmas traffic. At 70 years old I can only imagine how catastrophic an accident my reflexes would have generated. The fluid sprayed on the hot engine creating a cloud of smoke. I was afraid the truck was on fire. The fluid cooked off the engine as smoke and again luckily there was no fire. Now after extensive repairs, I am very nervous behind the wheel of this vehicle. This very dangerous situation with corrosion should be addressed as blogs on the internet indicate this dangerous issue has been ongoing for quite awhile. I have attached the invoice of the repairs required. I was in the drive through of a mcdonalds and had placed my order and was pulling to the window to pay when the brakes failed. Luckily I was only moving slowly at that time, thus able to avoid injuring anyone or damaging any other vehicles.

Brake pedal went to floor almost causing an accident before the vehicle came to a stop. Before the service light came on. The service light did come eventually at which time we checked the master cylinder which was extremely low so we filled it thinking that was the problem. The next day we noticed brake fluid dripping and after checking realized that at least one of the brake lines were were rusted through in several places and all of the other lines are terribly rusted and probably on the verge of leaking also. This is a truck that we usually pull our camper with. Luckily we were not pulling it at the time this occurred.

Was coming to a stop light and brake pedal went all the way to floor. Had to step on several times to get stopped. The factory electrical wire in factory loom in factory clamp hooked to brake line wore a hole through brake line to right front wheel. Wore through directly under the master cylinder. Luckily I was not going at high speed or this could have been a fatal incident!!!!!!!!! This is something that come from factory and needs to be addressed.

Brakes failed at highway speed, brake pedal went to the floor with very little braking. On investigation, brake oil would spray from the brake line under the truck.

Brakes failed while coming to a stop in light traffic. Braking action reduced to approx 10 to 20 percent of normal. Driver felt a "pop" and the brake pedal went to the floor, followed by a 'service brake system' warning message. A large puddle of fluid formed under the truck when parked and a quick look under the truck showed lots of fluid from the front of the bed to the rear of the truck. Further investigation showed heavy corrosion on all rigid brake lines. All brakes lines will be replaced. The failed line powered the rear brakes. This truck is only eight (8) years old. This could have been lots worse if the brakes failed one week earlier when I was pulling a camper through the tennessee mountains.

I went to put on my brakes, I first started to stop then my brake pedal went all the way to the floor. I hit a vehicle in front of me. The collision shop that I had it repaired at said the brake lines were rusted. After further investigation I read a lot of complaints about this same defect in chevy and gmc trucks.

I was approaching the stoplight fletcher drive and lee highway at approximately 25 MPH heading east on lee highway around 1600 edt in warrenton, va. There were four (4) cars waiting to turn left onto fletcher drive in front of me. The car in front of me came to a sudden stop. I applied the brake with approximately 2 car lengths in front of me. The brakes started to grab but then the brake pedal went all the way to the floorboard. I pumped the brakes and my truck continued to roll and then hit mr. [xxx] vehicle at approximately 5-7 MPH. I was unable to come to a complete stop until making contact with [xxx] car. I asked if he was ok or hurt and he replied yes, I am ok. Why didn't you stop?? I explained that I tried. I then suggested that both of us pull into the fauquier bank parking lot and exchange insurance information. At this time, I noticed my brakes had completely failed and the truck was leaking a significant amount of brake fluid onto the parking lot (coffee can or more in 10 mins). I stated that since it was a mechanical failure on my vehicle, I would feel better submitting it through insurance. I also showed him the leaking brake fluid. [xxx]. Asked why I was driving with failed brakes and I explained that the brakes had failed at the intersection, that my brakes were working properly prior to the accident and that my truck had just been picked-up from service at the dealership (country chevrolet) on monday with no problems. The dealership just informed me that all the brake lines need to be replaced and that they have corroded through and basically "exploded". A similar issue occurred with my 2003 gmc sierra in 2009, but with no accident. All brake lines had to be replaced due to corrosion. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Without any warnings when attempting to come to a quick stop brake pedal went to the floor and had no braking power. Avoided crash by driving onto a lawn. I have found that all the brake lines where they are attached to the frame in a plastic support under the drivers door have rotted through. Contacted gmc with no success just informing they are aware but no re-calls.
