Brake Hoses, Lines/piping, And Fittings problems of the 2005 GMC Sierra

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.

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.

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,.

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.

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

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.

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.

When applying brakes going down hill, put the brake pedal to floor and din't have any brakes. Brake line rotted.

I went out to move the truck and noticed there was fluid on the driveway. I examined the rear driver side and there was a brake line that had rusted through. I contacted the local dealership and they stated they were unaware of this being an issue with those trucks. I had researched and found that there have been multiple complaints to gm about this issue. Fortunately, this occurred when the vehicle was parked and did not fail while driving my family in the vehicle. What I have read is that the brake lines were manufactured with poor quality materials and that they fail. . Read more...

I was driving on a highway getting ready to make a left hand turn off the highway when all of a sudden my brake pedal went to the instead of continuing the turn I pulled onto the center median so I would not hit the on coming traffic. I ruptured a brake line and had to have my truck towed to a repair shop. After reading on line I understand this is a persistent problem with the Sierra and silverado. I also have read that gm is aware of the problem but refuses to issue a recall because they feel it is not a safety issue. We'll if I had not pulled the wheel back to the right and went into the median I would have been involved in a head on crash,I would call that a safety issue.

Was traveling on baldwin rd. , clermont county, ohio. I applied the brakes to slow for a corner and the brake pedal went to the floor board. I finally got the vehicle stopped and I realized what had happened. I had a discussion with a mechanic at my dealership while my truck was still under warranty about the condition of the brake lines in the engine compartment, and was told that the rust was just discoloration and nothing to worry about. When I called the dealership on 3/7/2014, I was told by the service manager that he was not aware of any investigation.

Brake lines heavily rusted. Looks like they will soon fail.

Helped friend with plumbing problem, as I backed out his drive way brakes seemed a little soft. At first stop sign brake pedal went down about 1/4 more on travel than normal. At next stop sign a car was already stopped, I applied my brakes, pedal to floor, no brakes at all. Dropped transmission into first gear, slowed some. The car at stop sign luckily proceeded on thru. I was not able to make a complete stop, and rolled thru the stop sign. Just about hit another car. I was able to nurse truck home. I have a garage at home with a car lift in it. I like working on old cars, and motorcycles. Worked on cars and trucks since I was 16, am 61 now, and by no means a novice working on, or racing cars!!! after checking trucks braking system. Left front steel brake line was rusted badly and had ruptured. As I continued checking the brake system, all brake lines extremely rusted. I have a 1952 styleline deluxe that the original brake lines look better. Truck my have seen snow 3 to 4 times in its life, pretty sad. I am lucky to not have killed some one or myself. Have pictures of brake lines and truck is still on lift. Extremely poor quality brake lines. GMC should recall. With out a dought sure some has been killed or injured, there will be more if not addressed now!!!!!!!!!.

The contact owns a 2005 GMC Sierra. The contact stated that while driving 35 mph, the brakes failed. The contact applied the emergency brake to stop the vehicle. The vehicle was inspected by the contact, who was a certified mechanic and the failure was diagnosed as a fractured brake line. The manufacturer was notified and informed him that there were no recalls for the vehicle. The vehicle was not repaired. The failure and current mileage was 117,000.

I was approaching a stop light and applied pressure to the brake pedal. My foot went to the floor and the truck did not stop. I was able to activate the parking brake and safely stop the truck. On inspection, it was discovered that the factory installed steel brake lines failed due to corrosion. The vehicle is well cared for and has no signs of body rust but the brake lines are almost completely rusted away front to back.

All brake lines badly rusted. Line above fuel tank rusted through and leaked while driving. Pedal went to floor. To avoid colliding with vehicle in front of me went off road. No damage to my truck.

I drove into lumber yard hit the brakes and they were gone. As my speed was low due to parking lot, I was able to stop without incident. Brake lines were completely rusted and all the brake fluid drained into parking lot. I had the brake lines repaired at considerable cost as they were all rusted. They needed to be custom bent by the shop. Luckily no one was hurt or killed. This should not have happened. I had rust in all lines and the grouping of lines over the drivers side frame rail next to front tire was the culprit area with all lines rusted thru. I had no stopping power. I had to use parking brake to stop.
