While towing our 42 foot camper with the 1 ton GMC dually truck we had a sudden loss of truck braking causing us to run thru a red signal light. The brake lines had rusted and burst leaving very little braking from truck. The brakes were inspected by a gm dealer only 6 months ago and were deemed ok after a 1200 dollar repair bill to replace rear brakes. . This is a real safety issue with such a catastrophic loss of braking . This truck is made for towing and should never have the braking ever be compromised. The truck has 125000 miles and should have had a more durable design integrated into the brake lines. There also was an enhanced chance for fire since brake fluid was sprayed on engine when brakes failed.

Metal brake lines rusted prematurely @ 29,900 miles causing brake line to rupture. This caused brake failure. Truck had to be towed to dealer who diagnosed rusted brake lines. For future safety all metal brake lines on truck required replacement. Failure occurred in work parking lot so no accident occurred due to failure.

Rusty brake lines lost brakes, think that a vehical should go 10 years without brake lines rusting away I was lucky when they broke I was home but just got back from another state and was at highway speeds.

I had a minor vehicle accident when I applied the brakes they went straight to the floor. I hand my vehicle towed to shop and it was found that the brake lines had rusted thru in the bracket on the firewall.

The contact owns a 2002 GMC Sierra. While driving 45 mph, the brake pedal was depressed, but the vehicle failed to stop. The contact veered into a ditch to avoid a collision. The vehicle was towed to an independent mechanic who diagnosed that the brake lines were corroded and needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 100,000.

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.

My pickup truck was in motion when driving on a city street I had to slow down. The brake-petal went almost completely to the floor. I almost hit the vehicle in front of me while trying to stop. After pulling to the side of street I checked under the truck and discovered that the rear metal brake line adjacent to the truck frame had rusted and burst.

Vehicle was stopped. Brake peddle went to the floorboard. Not able to pump up any pressure. Investigation showed brake fluid coming from perforated brake line at left front wheel. No braking action available! appears to be some type of corrosive reaction between the brake line and the clamps used to fasten the line to the chassis. Note: this vehicle has never been operated in snow or road salt to my knowledge.

Went to stop at traffic light and experienced brake line rupture due to excessive rust. Had to use emergency brake to coast to a stop. Fortunate no cars were in lane. $1200. 00 for repair of lines.

I was approaching a stop light driving on a 4 lane 55 mph speed zone. As I was approaching the stop light I starting pressing on the brake pedal. The pedal had no resistance it kept going to the floor. I started pumping the pedal trying to slow my truck down, no use. I pushed pedal all the way to the floor. This slowed a little. But not enough. I down shifted the automatic lever and starting guiding the truck off the road to avoid the stopped vehicles. I missed the vehicles. Luckily I was only 3 miles from home. I managed to limp home by driving very, very slow and using the gear shifter to slow me down. When investigating the cause at home I found the brake line on the right front had rusted through and there was a leak. All the brake lines on this truck are rusted and in bad shape. I called the dealer glenn Buick GMC where I purchased the truck new in 2003. I spoke to the service personal "corey" about repairing the rusted lines. He said GMC was not standing behind this "failure" ! I was on my own ! seems GMC knows of these failures and so do you and you have agreed not to make them stand behind it and you have chosen to allow more accidents to happen ! you = national highway safety what a shame ! shame on you and GMC ! had I not been "lucky" this could have been a terrible accident! any help in resolving this issue would be appreciated! this issue will only get worse ! as I am sure there are other trucks with this potential problem waiting to happen!.

While pulling out of my driveway I experienced complete brake failure. Looked under truck and brake fluid was everywhere and the brake lines were severely rusted and had busted. Looked it up and this appears to be a common problem with this model truck but there has never been a recall?! this issue needs to be addressed with gm.

Without any warning, my brake lines failed and I could not stop my truck. I live in the northeast and it would seem reasonable for brake lines to rust out. However, my truck is only 10 years old and I have spent thousands of dollars keeping it washed, including the undercarriage. I have never had a brake line fail on another car and I have driven some really old vehicles. I have also never heard of anyone I know having a problem with their vehicles. This is because it is a specific problem with GMC Sierra and chevy silverado.

I experienced a brake line failure on my 2004 GMC Sierra crew cab pickup truck. I was traveling at a slow rate of speed and coming up to a traffic light and the brake pedal pushed all the way to the floor board. The rear emergency brake was used to stop the vehicle. I found the area around the brake module, in the frame area under the driver's area, soaked with brake fluid and corroded brake lines.

A vehicle approaching from my left side was speeding and ran the stop light in front of me at approximately 40mph. I slammed on my brakes to avoid the collision and my brakes wet to the floor. I missed hitting the car by about 1 foot. At an inspection at a dealership it appears the brake lines had rusted through under the drivers side of the truck. Apparently form road salt corrosion,.

Again. My truck had complete brake failure again due to corrosion on the steel lines. This is an otherwise nice truck with brake lines that look like they've been in the ocean their entire lives. Gm dealer quoted over $1,700 to fix. Gm owned warranty company refuses to cover repair. Gm customer service tells me to pound sand.

Another gm rusty brake line failure while attempting to stop on a 2005 GMC Sierra 1500. I don't expect things to last forever, but brake lines are essential to the safety of a vehicle and they should not be rusting to failure at this point. I don't care what the climate is. At this point my truck is in the shop getting fixed on my dime (gm refuses to repair it). But they need to look into this. I have worked on/driven many much older cars in the same condition, and I have never seen brake lines rust to this extent in 10 years. My last car was a 20 year old monte carlo that still had original brake lines. In my opinion this has the potential to turn into bigger safety issue at some time. In my opinion, it is only a matter of time.

Tl-the contact owns a 2003 GMC Sierra. The contact stated while driving approximately 60 mph, the brakes were depressed and traveled abruptly to the floor. The vehicle failed to come to a stop until the emergency brake was engaged as the brake pedal was applied. The vehicle was towed to the residence. The contact discovered that the entire brake lines fractured due to corrosion. The vehicle not repaired. The manufacturer was notified of the problem. The approximate failure mileage was 73,000. Js.

Applied brakes to stop and brake peddle went to floor do to rotted brake line.

Brake line failed and broke, upon inspection all brake lines were corroded and brittle, had to replace all brake lines.

When trying to exit highway offramp brakes completely failed due to brake lines rusting through. Vehicle was brought to a stop with parking brake.

Brakes failed unexpectedly. The pedal went all the way to the floor and barely slowed down the truck at all. This was due to a brake line that rusted through. The repair was $765. Had I been in an area with higher traffic there would have been an accident.

Made a left hand turn at a traffic light after it turned green. I was the only vehicle at the time making the turn, nobody in front or behind me. Drove about 1/10th a mile to the next light, when it turned yellow, I immediately hit the brakes to stop. At first the brakes worked then my foot went to the floor, I had no brakes. I came to a stop in the middle of the intersection. I then backed up, to get behind the light. As I stated at the beginning, there was nobody in front or behind me at the other light making the turn with me, so when I was approaching the next light, I had nobody in front of me, behind me or to my right. The roadway was four lanes, two in each direction, with a center medium. I was driving in the left lane. So I am lucking to drive another day and someone else too. The cause of the problem is that the brake line that goes from the front to the rear, running along side the frame, on the driver side, rusted out and broke. I contacted gm about this, and after talking and complaining about what happened, they said there was nothing they could do for me. My problem is that, this is a safety issue, and they take no responsibility for it. I should have been at least notified in some way as an owner that my life may be in danger if I do not have my brake lines checked and replaced if needed. They no about the problem and are not contacting owners of my vehicle and others with the same problem. I am lucking to have not been hurt or killed or hurting and killing someone else. I did not know of the problem until after it happened. I am now faced with doing the work myself, which is a major undertaking, or having the local GMC dealership doing it for 1500+, which is where it is right now, waiting for my call. Thank you.

Brake line rusted thru causing the truck to lose brakes entirely. This vehicle has never been out of florida, and I am the original owner since new. Never driven on salty winter roads or snow.

I was traveleing at 35 mph and approached a stop light. The brakes failed and I went through the red light. I nearly was hit by oncoming traffic. The brake line has a sever leak at a rusted area in the line.

Heading into parking spot at walmart , applied brakes would not stop , heading head on into parked car , slammed emergency brake , put into neutral , finally stopped . Had to have towed to mechanic brake lines all burst due to rust , mechanic said cost to fix , approx. $1000 or more ? which I don't have . Thank god I was going slow and didn't cause any injury , pour design and pour quality parts per mechanic on gm's part , notice a lot of complaints on these era of trucks.

As I was traveling about 35mph approaching a red stoplight I proceeded to press the brake pedal all the way to the floor, with no braking of the vehicle. Luckily I was able to quickly shift the vehicle into neutral and engage the emergency brake and avoid collision. After further inspection I found the hard brake line running to the front left wheel had ruptured causing the loss of brake fluid. The line ruptured in an area where it was severely corroded and upon inspection, the other hard brake lines of the system looked severely corroded also. All will have to be replaced! this failure could have had a very bad consequences at a higher speed, closer proximity to other vehicles, or with a less experienced driver!.

I was traveling in rule area of mich. After dark,a deer jump out in front of me! I hit the brakes,a brief brake surge, then the pedal went to the floor! no brakes! the brake lines under the drivers seat area were rusted through! I stop at a gas station. I found brake fluid all over and a man asked me what had happened,I told him what I found , he and I couldn't believe they were so rusted out ! my truck is in very good shape! except for the brake lines! it's got a stainless steel exhaust system but they scrimp on one of the most critical systems for safety ! unbelievable! by the grace of god I didn't hit the deer! but what if it had happened in town or if the deer was a child! thank god it happend the way it did and no one got hurt!.

Tl- the contact owns a 2003 Sierra GMC. The contact stated that while driving the vehicle at approximately 25 mph the contact pressed on the brakes and the brake line broke. The contact used the parking brake to stop the vehicle. The vehicle was not taken to the dealer to be diagnosed. The manufacturer was not made aware of the issue. Rwk.

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.

The vehicle was purchased new and has been regularly maintained. The brake lines and frame are heavily corroded. While pulling out of a parking spot on 10/26/14 brakes were applied abruptly which caused a rupture of the corroded brake lines. All brake lines will need to be replaced in order to safely return the vehicle to service. Other family members have 2004 chevy yukon and 1994 GMC 2500, both vehicles had brake lines fail due to corrosion and required complete replacement in order to safely return the vehicles to service. This is a serious safety concern and these brake line failures are not normal wear and tear. I have had several vehicles much older than this vehicle which still have stock brake lines with no corrosion.

My 2000 GMC Sierra 1500 pickup, which has spent its entire life in virginia, lost its brakes while I was towing a dual-axle trailer and boat. Thanks to god's protection, this happened right as my made my final stop right in front of my house, so I was barely moving. Had this happened just moments earlier, I would have been travelling around 50 mph on a winding country road. I looked under the driver's side door and found the brake line and fluid running from it. While there was surface rust on the lines, I wouldn't say it appeared that a failure was imminent. Clearly, inferior materials were used for the brake line when less corrosive materials should have been used. Gm should acknowledge their poor choice of materials and provide, at the very least, replacement brake line sets. Their current "deeply discounted" set costs more than an aftermarket set.

I drive a company truck during the week and make a habit of driving my Sierra once a week as well. I was going down the driveway to the main road when the pedal fell to the floor. No brakes whatsoever. I used the emergency brake to come to a safe stop. I looked under the hood to realize that the brake lines were rusted and had blown a hole. This truck is not that old and I do not live in a northern state where salt corrosion is an issue. I baby my truck and keep it up. I later did a search on the web an found out that thousands of others are having this issue as well. This is ridiculous, this is a bad material choice for brake lines. GMC needs to realize this and recall all of us and install coated, or better yet, braided/poly-covered lines to make sure this never happens again. What if I were traveling at a higher rate of speed and had my family in the car? I can see their stand on this being a maintenance issue, but I have friends with early 80's and 90's model trucks that still have the original brake lines in them, not corroded or rusted, and still work great. Get on the ball GMC and take responsibility for this.

Brake line ruptured leading to complete loss of braking. Hit car in front of me as it came to a stop. This is the second time that the brakes have failed due to brake line rupture due to excessive corrosion of the brake line metal. Please force gm to issue a recall.
