While approaching an intersection I applied the brakes the pedal went to the floor ABS light came on and the was total brake failure. Guided the vehicle off the road and had it towed to the shop. They found rusted brake lines at the ABS valve along with a rusted backing plate for the valve. In order to improve vehicle safety the lines will all be replaced with stainless steel so this doesn't happen again. This is a very poor design since a single failure should not cause total failure of a supposed dual breaking system.

Total brake failure while stationary and engaging drive mode in driveway. Brake pedal went to floor. Parking brake also soft and ineffective but restored normal condition shortly thereafter.. No brake or ABS system service alerts or fault warnings prior to failure. 'service brake system' alert present after failure. No obds codes present. Suspect brake line corrosion. Approximately 170,000 miles. Recent tire/brake/alignment inspection revealed no issues. This is a very clean, "new to me" used vehicle with an excellent record of service.

While traveling home this morning from a ball game on nc back roads with our two children, my wife [xxx] said the brakes failed and the warning light came on and the buzzer sounded. Unable to stop, they rolled through a stop sign and pulled into a church parking lot. Upon inspection, brake fluid was dripping from a rusted brake line just inside the left rear wheel. I purchased the vehicle new and it has been in the charlotte, nc area most of its service life. Annual trips to northern michigan with proper post trip washings should not have created this amount of rust and corrosion on key components such as the brake lines. This known problem must relate to the inferior quality of metal of gm allowed the supplier to use. The numerous failures I've read about have not been limited to the northern climates and consequently will result in numerous deaths as these vehicles age further. Answering the problem last fall with pre made replacement brake lines for customers to buy and have installed falls short of meeting gm's obligation to deliver safe and reliable vehicles. The affected vehicles should be inspected and repaired proactively by gm asap. Several years ago subaru promptly recalled their corroded brake lines; why has gm been given a pass?

All automobiles in north-america should have stainless steel brake lines and fuel lines to prevent corrosion, it only makes sense and its not the end of the world as far as cost; brake failure is probably the most dangerous thing that can happen that can be life threatening. I am aware that auto manufacturers want us to replace components and make money down the line, but brake components such as brake lines have to be excluded from this.

Coming to a stop to make a left hand turn, light coating of snow on the road made it slippery, ABS braking cycled I held brake pedal down as the manuals say to do with ABS system, truck slowed ABS cycled again and then pedal went to the floor. My vehicle ended up sideways in road and thirty feet from my turn and nearly in a ditch, I then backed up to make my turn and brakes went to the floor again as I stopped to enter my road , fortunately my home was only about 500 yards from this spot. I had almost no brakes at all as I entered my driveway and parked.I then inspected fluid level in master cylinder which appeared full , from there I followed line down to the ABS module to the braided brake line and still saw no leaks, then followed the braided brake line to the brake line tubing to the frame behind the wheel well where the line closest to the wheel well was leaking fluid and it had sprayed all over the line and under carriage and frame and wheel housing shroud. The line is rusted out and burst the truck has less than 80000 miles on it and is well maintained and I bought this truck new with 8 miles on it and paid $43000 for it. This is horrendous and incredibly dangerous there was no stopping power at all, had this happened on the highway or at a busy intersection there would have been a collision.

Was backing up into parking space and applied brakes to stop. Brake pedal went all the way to the floor with no braking capability. Had vehicle towed to service facility and they reported that the front brake lines had rusted through causing fluid to be pushed out. I thought that these vehicles had a dual brake cylinder so that there would be braking capability on the rear brakes but that did not happen. Fortunately was going slow and applied emergency brake to stop. Paid repair facility to replace front brake lines. Second incident occurred on november, 2013 where I applied brakes prior to moving transmission from park to drive while on a hill. When I applied brakes the pedal went all the way to the floor with no braking capability. I determined that the left rear brake line is spewing fluid. Again, no braking capability in the front brake system. Had vehicle towed to a repair facility. I assume that the rear brake lines have also rusted through. I have read numerous incidents on internet about gmc brake lines rusting. This is a serious problem as there is no braking ability at all except for the emergency brake if one of the brake lines rusts. First, these lines should be made of materials that do not rust. I have multiple 60's and 70's vehicles where the brake lines are not rusted. Second, there is a problem in the dual master cylinder of these vehicles where they fail to work when either the front or the rear lines fail.

While driving down a hill in orillia ontario canada, I had a sudden loss of brakes. I was able to swerve through 3 lanes of traffic and after nearly hitting another car in a service station parking lot I brought the vehicle to a stop. My brother checked the vehicle and found that all brake fluid had leaked out of a ruptured corroded brake line next to the ABS sensor under the driver side of the vehicle. Please add my name to the list of over 110 other complaints regarding brake lines which are corroded.
