On february 3, 2015, I noticed my brakes pedal were going closer to the floor. I got home and noticed that my brake lines at the rear was leaking brake fluid onto my driveway. I attempted to pull the vehicle up further in the driveway and the brake pedal went all the way to the floor. I had to push in the emergency brake. On february the 7th I contacted my gmc dealer in wendell, nc. I advised them that I was getting aaa to tow my vehicle in due to brake line problems. The dealer repaired my rear and front brake lines and charged me a total of 1,949.00 and said that their was not a recall on this part.

I was pulling out of my driveway in my hummer h2 when the brake pedal went to the floor. I got out of my h2 and noticed a large amount of brake fluid running out from under the rear end near the left rear wheel. I looked under the vehicle and noticed a brake line was rusted in two. I checked under the hood and saw that the brake fluid reservoir was completely empty.

I was driving down the highway interstate 70 in maryland and went to apply my brakes . As I applied the brakes , the truck pulled hard to the right ,and the brake pedal went to the floor . If I would not have swerved onto the median , I would have ran into the back of another vehicle . After stopping , I looked under the vehicle and observed a puddle of brake fluid on the ground ,and the front suspension was covered in brake fluid. After further inspection, I noticed that all the brake lines were corroded. Gm states that your vehicle can still stop if you lose one of the brake lines . In my situation , I found this to be a false statement . This is a very dangerous situation ,and I was very surprised when I took the vehicle into a certified gm dealership and found that they would not do anything about this issue. They offered a voucher for 1000 towards a new vehicle . I own a 1968 camaro that is all original ,and I do not have any rust issues with the brake lines . How is this possible that a car 35 years old does not have this problem ? And even more crazy , that gm turns a blind eye to this dangerous issue . Needless to say, I will not ever buy another gm product !

Brake lines rusted through and failed catastrophically and without warning causing a complete loss of braking while stopping for a red light. Since the entire system was rusted, there was no reserve braking from the dual system. I was traveling at a moderate speed and was able to recover without an accident. I replaced all the brake lines at a cost of $1100, not knowing that this was a common defect in gm vehicles. I saw today in the new york times that many other gm vehicle owners are experiencing the same problem. It is apparent that gm engineers have not heard about the concept of galvanic corrosion and used the wrong materials for critical components.
