Brake Hoses, Lines/piping, And Fittings problems of the 2007 GMC Sierra 1500

At 50000 miles had to replace both front hubs bearing where destroyed. At 6500 m iles brake lines ruptured while driving.

Rusted out brake line at 72000 miles. What a disappointment but it doesn't look like I am the only one. Its a shame gm doesn't man up and correct the problem of rusted out brake lines. Luckily I was in front of my house when it failed and not running down the road pulling my 4000 lb. Boat. And yes I have read all the info online about the nhtsb investigating this problem and let gm off the hook by saying owners should wash their cars to remove the road salt that caused this problem. I guess Ford and Dodge owners crawl under their trucks in the winter and do this as there was no investigation on them. By the way I live in TN where winters aren't that bad. And one other thing what marketing buzz saw decided it would be better not to have a split brake fluid reservoir so at least I would have 1/2 of my system, had no brakes front or rear because of this.

The contact owns a 2007 GMC Sierra 1500. The contact stated that the vehicle experienced a loss of braking ability. While driving various speeds, the contact was able to stop the vehicle by using the emergency brake. The failure occurred without warning. The vehicle was towed to the mechanic where it was diagnosed that the brake lines were defective and needed to be patched. The vehicle was repaired; however, this was the third instance of the failure occurring on the vehicle. Wildcat Chevrolet (5525 hopkinsville rd, cadiz, ky) was contacted and confirmed the failure, but the vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 80,000.

Brake lines failed on my 2007 GMC 1500 and my 2007 GMC 2500. It appears to be a common problem with GMC vehicles from 2003 to 2009. Why wasn't these vehicles recalled for this. I was told that GMC was offering a discounted price for failed brake lines, but the dealer charged me full price. $1,667. 00. The discounted price was supposed to be $500. 00.

I went to a local recycle business to drop off some cans. Upon entering the building at about 10 mph, this guy motion me to stop and walked in front of the truck. I hit the brakes and the peddle almost went to the floor, but did stop. Just missing the guy that walked in front of me. Realizing that a brake line broke and that the dealership wasn't far away, I drove really slow to get there. I left it over the weekend. Monday they found that the brake line that runs from front to rear rusted and burst. $ 463. Later I took the truck home. After crawling under the truck when I got home, I noticed more brake and fuel lines with allot of rust. I applied some paint that's supposed to slow down corrosion. I'm glad I wasn't on the highway with my grand kids in the truck. Or worse, the fuel lines could break. I believe there should be a recall on the brake and fuel lines. How much would it have cost for the manufacturer to have installed stainless steel lines when the truck was built? I'm sure it wouldn't have been much. I hope nobody has to die before anything is done. Thanks for your attention.

While driving the vehicle at a rate of 20 mph and started stopping and notice the brakes where going out. I had then lost brake pressure altogether. Used the parking brake to get stopped after putting the vehicle into neutral. I had the truck towed to my local independent mechanic and he checked the vehicle and found all the brake lines to be rusted out, and had lost all brake fluid. Upon finding this he found the majority of the undercarriage to have severe rust damage an several parts also.
