2007 GMC Sierra Classic: brake failure

Filed Jan 4, 2015 · Brakes · 58,255 miles · IN

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!

2007 gmc sierra classic with approximately 54,000 miles was being driven into a garage to have wheels balanced. As the technician applied the brakes entering the garage, the brake lines on the front drivers side of the vehicle ruptured and the brake peddle went to the floor. Brake fluid poured out onto the floor and the brakes became completely unusable. If this had happened a few hours earlier in the day as I was traveling on steep mountain highways in west virginia I have no doubt an accident and probable fatality would have occurred. All recommended maintenance had been performed at the gm dealer where the truck was purchased and no warnings from gm were given that the brake lines were showing any signs of wear or that a complete brake failure like this could happen.

I was driving my 2007 gmc siearra classic 2500hd wt and my brake line failed. I went threw the stop sign out onto a main road and just missed getting t-boned by a tractor trailer. I had no brakes at all. My brakes are all up to date. Brand new brake pads and rotors. I read tons of complaints online of people with the same problem with gm vehicles brake lines rusting out prematurely. My truck only has 32,164 miles on it and is well taken care of. I get compliments on my truck everywhere I go. I got nowhere with gm corporate or marty's gmc in kingston,ma where I bought this truck brand new. They all pretended they do not know anything about these brake lines failing. They now use a different coated brake line to replace the cheaply made brake lines at the customers expense. Please make gm do a safety recall on these failing rusting brake lines before someone gets killed. I was almost not here to tell my story.
