Brake Fluid Leak Problems of GMC Sierra - part 2

Entered parked truck in personal driveway. Applied brakes prior to stating and petal went to the floor with no warning. Opened hood and noticed big puddle of brake fluid in driveway. Added more brake fluid only to see it leak right back out on the ground. Contacted repair station, had truck towed. I was notified by the repair station that there was severe brake line rust and they could only complete a partial repair at a local area of the broken brakeline due to the major cost involved!.

Was coming up on a single lane bridge . When I started to brake my foot went to the floor. Lucky for me I did not have any oncoming traffic, and drove over the bridge safely. I then noticed check brake system sign on dash board. Pulled over and there was brake fluid dripping from the drivers side around gas tank area. The line was corroded and burst.

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.

I left my house for work and approx. 3 blocks from my house I attempted to slow down to make a right hand turn. I pressed on the brakes and the pedal went all the way to the floor. I had no brakes. At this time and this was the first time, the brake light on the dash came on. I was driving at 30 mph with no brakes, I coasted into a parking lot and used the parking brake to stop the truck. Outside and under the drivers door of the 2004 Sierra extended cab there was brake fluid leaking. The 8 year old truck had rusted brake lines that failed. My concern is that I lost all brakes without warning. After a little research I noticed many of these trucks have the same problem. They are 5000 pound torpedos on the road and without warning. Will something be done before a serious accident occurs? I tried contacting GMC via their website e-mail but an error message occurred. Try a complaint on their site. . . . . It don't work!!!.

Total brake failure occurred while moving out of a parking slot. Pedal went to the floor; upon investigation found brake fluid pouring from left rear wheel area (could not determine actual location); suspect corroded steel brake line. Further investigation found evidence of fluid leakage in home driveway where parked overnight. This is 2nd brake line failure on this vehicle (1st was January 2012; replaced line but was advised by mechs that other lines were ok at the time, this is two brake failures in 7 months on this truck).

Vehicle was driven on a driveway and the brake pedal lost complete resistance and went flat to the floor. Total brake failure occurred without any warning indicators. Inspection of the metal brake lines positioned near the left front wheel revealed that all four lines showed severe signs of corrosion and one of the lines had produced a hole therefore leaking brake fluid.

Brake fluid all leaked and I barely stopped the truck on my home driveway. Dealer says I need to replace all four metal brake lines.

I was driving down my street and tried to stop at the stop sign. The brake pedal started to stop the vehicle and then suddenly went straight to the floor. I drove the one block back to my house and parked the vehicle. I observed a large puddle of brake fluid under the drivers door. Upon inspection, I saw a bundle of rusty brake tubes running down the frame rail of the truck. I had the truck towed to my mechanic.

I got into my GMC applied the brakes before starting the truck and all of a sudden the brakes went to the floor. I got out and discovered fluid dripping from under the truck, on the drivers side, about in line with the back of the drivers seat.

While pulling a small enclosed trailer and going down a hill I experienced a complete brake failure. I had absolutely nothing for brakes. I ended up going through a redlight and missed any vehicles in the intersection, started to downshift to slow my speed. Crossed over an intersection for a bike trail with noone in the way. Then had to make a hard right turn to go under a train tressel narrowly missing an on coming car. When I finally got the vehicle stopped I had dropped vertically 80 + feet in the matter of less than a half mile. On the ground was a puddle of brake fluid fromthe corroded brake lines that had burst rendering my truck in to an unstoppable downhill bobsled. The weather conditions we sunny and 80 degrees. Luckily noone was in my way and I was able to miss any objects and steer the truck to a safe spot. I am also thankful that neither of my kids were in the truck with me at the time of this incident. I feel that there should be some accountability in to what a manufacture uses for vital safety items in a vehicle. Brakes lines should be a part that should outlast the usefulness of the vehicle . Not something that should be a possible failure point any given time. This is a matter of public safety how many more people have to die or get injured due to a cost savings of using regular steel lines on the one part that makes you vehicle stop? I have heard of plenty of people with multiple vehicle types who have had their brake lines fail. This is just unacceptable thank you for anything that you may try to do on this issue .

The contact owns a 2003 GMC Sierra 1500. The contact stated that the front and rear brakes failed and would not respond when depressed. The contact examined the vehicle and discovered that the brake lines were corroded and leaking brake fluid. The vehicle was not repaired and the manufacturer was not made aware of the failure. The VIN was not available. The failure and the current mileage was 108,000.

I stepped on the brake pedal to shift the truck from out of park and the pedal went to the floor. I got out of the truck and found a puddle of fluid in the area in front of the drivers side rear tire. It appeared as though the brake line going to the back brakes ruptured in the area behind the gas tank.

While my buddy was backing my boat trailer and boat into the water for me, he yelled to get out of the way, the vehicle was sliding down the boat ramp. He was able to stop before going into the water. I told him I just had the brakes done this fall and he said the brake pedal went straight to the floor. I got in to pull the truck up and the pedal did go straight to the floor. A large puddle of brake fluid was on the ground at the boat launch. I had the vehicle towed to the repair shop and found that the brake lines had corroded so bad, they rusted right through and lost almost all of the brake fluid. The lines were so bad, I needed to get the entire brake line system replaced.

While driving in town I noticed my brake petal was feeling soft, the next time I depressed the petal, it went all the way to the floor and the vehicle would not stop at all. I coasted into a parking lot and used the emergency brake to complete the stop. I looked under the vehicle by the drivers side door and witnessed the fluid dripping out of the brake lines. The car was towed to a local mechanic, where he discovered all four lines had failed at a point where all the lines were held together by a mounting backet, just under the driver's side, and mounted to the frame. Had I been at higher speeds and had to make a quick stop the outcome would have been much worse.

The brake lines are rusted through allowing all of the brake fluid to leak from the vehicle resulting in no brakes.

The contact owns a 2001 GMC Sierra. The contact stated that while reversing from a residential driveway, she the brakes failed and brake fluid leaked from the vehicle abnormally. The vehicle was taken to the dealer who stated that they needed to replace the brake lines. The vehicle was repaired. The manufacturer was contacted and stated there were no recalls for the vehicle. The failure mileage was 88,000 and the current mileage was 100,005. The VIN was not available.

Brake line to the front passenger wheel blew apart causing the brake fluid to leak out, and dramatically decreased the stopping ability of the vehicle. Had this line replaced by a local repair shop, and was notified by personnel that all of the lines were in bad condition, and needed to be replaced soon.

Attempting to stop for a school bus, as I pressed on the brake pedal it went to the floor and the truck did not come to a complete stop. After pulling over, it was discovered that the brake line was leaking fluid on the ground. Upon further inspection, noticed the brake lines are corroded. Be it know that the frame and body parts on this truck are also rusted as to not pass state inspection. The truck is just over 10 years old and unsafe to drive due to multiple manufacture defects.

The contact owns a 2001 GMC Sierra. The contact stated that while driving 20 mph, the brake pedal depressed to the floor. The vehicle was coasted to the side of the road and the contact noticed that there was a brake fluid leak. The vehicle was then towed to an automotive shop, where they cut off the rotten portion of the brake line and repaired it. The brake failure occurred a total of three times. The dealer did not diagnose the failure, but a private mechanic repaired the brake lines. The failure mileage was 130,000 and the current mileage was 145,000.

I was driving and went to apply brakes for the stop sign ahead, and I had no brakes. Once I had the truck home I parked it. I determined that the brake lines had rusted through by having a piece of cardboard under the truck to locate the leaking brake fluid. I'm so lucky that I didn't have a camper on the truck and had gone on vacation to colorado, as I intended this to be my recreational vehicle for this purpose. I am haunted by the possible scenarios and crashes that could have occurred to me and my family. Wife, son, and two daughters. This needs to be addressed before other human beings end up seriously injured, traumatized, or death being very highly likely. So I have a near new truck sitting in the yard for nearly the past five years. My attempt to install after-market brake lines has been a failure. Gm should be responsible for this catastrophic failure. I know as time goes by other brake lines on these models will rust and fail. I will be here as a witness, and so will the truck as I have refused offers to sell it.

2000 GMC Sierra brake line corrosion issue. Ruptured steel line below the drivers door. 1). After a hard stop due to other motorist pulling out in front of me the brakes were not as firm as before. 2). The next morning I found an oil spot on driveway and brake reservoir half empty. Investigated and found heavily corroded brake lines in a group of four below drivers door against outside of frame. One line leaking fluid badly. 3). I went to general motors to purchase new brake lines and was told that the come in bulk rolls only. They have to be bent to shape and flared to be installed. This seems like a very labor intensive repair and would be very costly. I am weighing my options.

My front brake line corroded and ruptured and started leaking fluid. I had no brakes and had to towed for repair.

The first incident I was pulling out of a parking spot and noticed my brakes were gone. The pedal went all the way down to the floor. Got out of the vehicle and there was brake fluid leaking from underneath the truck. Took it to the mechanic and was told the brake line was rusted. Had it repaired and since then we have had 4 additional incidents.

While driving 5 mph consumer lost power steering and braking control. Consumer managed to pull over, and had the vehicle towed. Dealership was notified, but did not resolve the problem. Consumer states he stepped onto the brake pedal and heard a loud explosion under the hood. The consumer immediately lost brakes and steering and smoke also poured from under the vehicle. Once he vehicle was stopped the consumer exited the vehicle and saw fluid pouring from the vehicle onto the ground. The hood was opened and the consumer saw the vehicle was taken to two different dealer but the found nothing wrong. The dealer replaced the hydrobooster assembly accumulator which had come apart.

When applying brakes, they vibrate/ braking distance is extended. Dealer has turned, and then replaced front rotors every 5000 miles. Also, rear wheel cylinders were replaced due to fluid leak.
