Brake Hoses, Lines/piping, And Fittings problems of the 2002 GMC Sierra

The metal brake lines have corroded badly and now failed. Very unsafe, crash waiting to happen.

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.

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

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.

Dear sir or MA'am, I have a 2002 GMC Sierra truck that I bought new in 2002. The brakes recently failed completely while my wife was driving on or about September 26, 2014. The brake pedal went to the floor without significant braking action. Fortunately she was able to stop safely and was not involved in an accident. Upon examination, the brake line to the left rear wheel was completely rusted through. I examined the rest of the lines and noticed that the brake lines, the transmission cooler line and the fuel line all show signs of major corrosion, especially along the frame. I have less than 43,000 miles on this truck and it was garage-kept the first nine years I owned it. I live in ky where the roads are only salted a few times a year. The rest of the vehicle is relatively rust free. The truck is unsafe to drive now. Even if I patch the leak, the rest of the lines could fail at any time. I could suffer catastrophic brake failure while towing my boat or horse trailer or simply going down a hill. Furthermore, the fuel lines are under considerable pressure and if they rupture, there could be a very dangerous fire hazard. If the transmission cooler lines rupture, I could have a complete transmission failure. I have read that this is a known issue with Chevrolet and GMC trucks for years 1999 to 2003 and that the nthsa has looked into this in the past. If other trucks are in the same condition as mine (and I believe there are), there is a major safety problem on the roads right now. Yet, to date no recall has been issued. I think this is courting disaster. It is my opinion that lines made with inferior steel were used in the construction of this vehicle, yet gm refuses to acknowledge the fact. I urge you to look further into this matter. This is nthsa case number: 699264.

I was driving approx 35 mph when a dog ran in front of my vehicle. I applied the brakes to avoid hitting the dog. A moment later I went to apply brakes to slow down for an unfamiliar turn and my pedal went to the floor. I managed to downshift to come to a stop and upon inspection, noticed a hole in my drivers side rear brake line. All of the brake lines have a severe amount of rust. The bundle of lines running along the frame on the driver's side are the worst.

I was slowing to a stop light from residential street,into a main road, and brake pedal went to the floor. I pumped brakes and recovered pressure and stopped. I then proceded on the main road to next light. After being at the light with my foot on the pedal for approx. 15 sec. The pedal went to the floor and truck began rolling forward. I let pedal go and pumped and presure came back and held for about 15 more sec. Then failed again with truck rolling forward. I then drove the truck directly to the shop about 4 miles away. I was informed that a very alarming and common occurence with 99-06 gm trucks occured. My brake lines had rusted out completly. 650. 00 bucks later I'm back on the road. I was told to look at this site and I was amazed at how many other vehicles have reported this problem. I was wondering if gm would be so kind as to at least pick up the cost of the parts which I was told around 100. 00. Wishful thinking I guess.

Brake line burst when brakes were applied. According to multiple repair facilities all brake lines are extremely rusted and must be replaced. Rear brake components also rusted and must be replaced. Cost of repairs exceeds $3000. 00. I've had several vehicles the same age ( with more miles ) that don't have nearly the same amount rust even though they too have spent their winters in michigan. Stopping a vehicle has to be the most important aspect of a vehicle to get correct. How is it that manufactures are not required to use the best product available for brake lines?.

I have a 2002 GMC Sierra and just pulled out of my driveway going down the street to stop sign and brake peddle went all the way to the floor causing me to go thru stop sign. Lucky no one was going the other way! managed to make it back home and noticed driveway all wet . Looked under truck and noticed the break lines all rotted! I cant believe that general motors would make steel brake lines knowing that steel will rot !did they just figure that out? I thought they should know better!!!! why don't I here about other vehicle makes don't have this problem. Did they just learn about steel? this is and important safety item and breaks need to work all the time. I also noticed the my fuel lines are showing the same signs. Gm should repair and learn from this bad choice to install inferior equipment for such an important system in any vehicle. I have since repaired my break lines at a very expensive $1,500 !.

The contact owns a 2002 GMC Sierra 1500. The contact stated that when he applied the brakes, the brake pedal went to the floor. The contact was able to avoid a crash and cruise to a stop. The vehicle was taken to the dealer who determined that all of the brake lines were corroded. The vehicle was not repaired. The failure and current mileage was 140,000.

As many other GMC/Chevrolet truck owners, I am experiencing premature brake line rust issues. Luckily I was not involved in an accident, but a rusted brake line failed coming to an intersection. When the brake pedal was pushed, I felt a slight resistance and the brake pedal went straight to the floor.

The brake lines in my 2002 GMC Sierra truck have corroded to the point that fluid is being lost and braking is being negatively affected. This was found during a routine oil change, luckily there was not a incident on the road. My truck is well maintained, I understand there are thousands of other complaints.

Description: 2002 GMC Sierra?82,xxx. 00 miles. While dropping my daughter off at school, I stopped at a light, accelerated to make it up the hill, and as I came over the horizon I proceeded to stop, when I depressed my brake pedal to slow down, the pedal went right to the floor. I almost ran into another vehicle and had I not thrown the car into low gear, and depressed my emergency brake, I am certain that we would have smashed into the school bus in front of us. My wife called aaa, and had the car towed to the local GMC dealer. It seems that the entire brake line system is rusted out, and that this was the first line to blow. They had the audacity to tell my wife that the repairs would start at $3,300. 00 and would not guaranty that it could not be more expensive than that!. We take good care of the truck, last year we had all the brakes done, new tires, and recently had a new head gasket installed, and the oil changed, so it is obvious that the dealer does not ever do a thorough vehicle inspection. We cannot afford the shell out the money for these repairs, and I am hopeful that there has been some kind of a recall for this, since I see so many complaints about the same subject? please help!.

Xmas tree shopping w/family very long stopping distance, then no brakes. I made repair at holding bracket near left front wheel on frame. Then on 2/25/2014 another brake line rust failure near but in back of abs module to back wheels. I replaced that section . Today 3/15/2014 another failure at the first spot,holding bracket near left front wheel on frame. All this on 2002 GMC Sierra,funny I have a 2002 Ford taurus almost the same mileage no brake problems.

I was lucky and not moving when this occurred for the second time. Once again I was getting ready to leave in my truck when I stepped on the brake pedal to shift out of park and the brake pedal went to the floor. Should I take my chances on this happening a third time? perhaps I won't be so lucky and there may be an accident involved along with possible injury or death. I did find a recall for tailgate straps for this truck but not for corroded brake lines that are bursting? I find that to be unacceptable. What are the chances of someone dying from corroded tailgate straps? this is an incredible safety issue affecting millions of trucks and there needs to be a recall issued to have these brake lines replaced with stainless steel so as not to have this problem repeated in the future.

While driving my 2002 GMC Sierra I depressed the brake peddle to stop at a red light. The brake peddle went all the way to the floor and the truck continued forward. I swerved off the road to miss hitting the car in front of me. After inspecting under the truck I noticed one of my brake lines had rusted completely threw and the rest didn't look much better.

6/5/12 after only 54k miles on my 2002 GMC Sierra 1500 2wd pickup, I experienced an instantaneous and complete brake system failure as a direct result of a corroded brake line(s), which burst, causing a complete loss of brake fluid and pressure. The failure occurred one brake application after exiting the off-ramp of a highway; I was very fortunate that the failure occurred at low speed (approx. 15mph) while entering a parking lot. There was no collateral damage or injuries involved. Further inspection by the gm dealer reveled that all of the associated brake lines were heavily corroded and prone to failure at some point in the near term. The gm dealer offered to repair the one brake line that had failed for $600. 00 and indicated to me that replacing all necessary brake lines would be cost prohibitive. I elected not to have gm repair my vehicle; since the cost for replacing one brake line @ $600. 00 is ridiculous! further, replacing the failed brake line only was not acceptable to me since the associated brake lines are close to failing as well. I took the vehicle to a local reputable auto repair facility, who offered a much more reasonable quotation and who performed a comprehensive inspection/repair of multiple suspect brake lines in order to make the vehicle truly safe. I am not happy with gm due to their non-responsiveness of this very serious mechanical problem and associated risk to public safety. I do not believe it is reasonable for brake lines to fail due to corrosion within the first ten years of operation; especially, for a vehicle with only 54k miles. This is truly a public safety issue that needs to be addressed, however, I have no confidence that gm will act without federal intervention. Disappointed in gm -.

The contact owns a 2002 GMC Sierra 2500hd. The contact stated that the front brake lines failed and the rear lines were very close to failing. The contact took the vehicle to the dealer for service and was informed of the failures. The failure and current mileages were 108,000. The VIN was not available.

100% brake failure due to ruptured metal brake line, severe corrosion. All lines require replacement. GMC notified, no replace parts supported by manufacturer. Truck stopped with use of emergency brake.

The metalic brake line tubing ruptured causing brake failure while traveling 50 mph on a downgrade. The metal line above the rear axle, passenger side, corroded through and spewed brake fluid all over. The corrosion point is about 7-10 inches forward of the junction where the brake line transitions to rubber hose that goes to the rear axle junction. There is also an unusual amount of corrosion on the gas fuel filter fittings located just forward of the gasoline tank. I was able to slow and stop by downshifting and using the emergency brake. Brake lines should not corrode and fail in any climate on a 9 year old truck! they should not corrode period.

Brake line burst open while applying brake to park vehicle on an incline. Brake pedal went straight to the floor. Line was leaking where lines run along the frame under the drivers side front door. After further inspection all brake lines are extremely corroded and near rusted through.

The contact owns a 2002 GMC Sierra. The contact stated that the vehicle was taken to a private mechanic for service and the mechanic stated that there was rust found in the drivers side brake baking plate and brake line. The private mechanic also stated that there may be safety related failures involving the suspension and brake pedal because the pedal had to be depressed all the way to the floor before the brakes functioned properly. In addition, the contact also stated that the safety belts failed to open and close properly. The vehicle was not taken to an authorized dealer and the manufacturer was not notified. The vehicle was not repaired. The failure and current mileages were 101,950.

Brake line tubing.

The contact owns a 2002 GMC Sierra denali. While driving 25 mph and attempting to stop, the contact noticed that the brake pedal extended to the floorboard. The contact pulled over and also noticed that brake fluid was leaking on the driver side. The contact later inspected the vehicle and discovered that the brake lines were corroded. The dealer and the manufacturer had not been notified. The failure mileage was approximately 75,000.

Brake failure. Sudden brake pedal to floor. Brake fluid on ground in area under driver. Towed to dealer. Dealer replaced rusted out front brake lines from ebcm to both front wheels.

Brake lines are rusted out badly and one rear left line rotted through and began to leak. When the brake lines were inspected all the brake lines were found to be severely rusted.
