Brake Fluid Leak problems of the 2000 GMC Sierra

As I was approaching a stop sign at 30 mph, I went to apply the brakes and the brake pedal went to the floor board. I pumped the brakes a couple times to regain pedal pressure with no luck. I was lucky that no other cars were at the intersection or else there would have been an accident for sure. I made a quick right hand turn and used emergency brake to stop. There was a puddle of brake fluid coming from the abs module underneath the drivers side door. Upon further inspection, the brake line ruptured due to rust and corrosion. I am relieved that no one was at the intersection and that I did not have my wife and 3 kids in the vehicle at the time the brakes went out. I have owned many vehicles and never had a single vehicle where metal brake lines have rusted out. I have owned this truck for 10 years and now question gm and their quality and integrity. At this point, I probably won't buy another gm truck because they rust out in less than 10 years and my family's life was at stake for a design/quality flaw. I now have to spend $1000+ dollars to replace all brake lines on my truck when gm could have installed stainless steel brake lines in the first place. Disappointed GMC truck owner.

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 .

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.

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.

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.
