Noticed a puddle of fluid on the garage floor. Investigated and found it to be brake fluid. The entire reservoir emptied on the floor after a day. I had a hole in one of the brake lines under the drivers side. Looking under the truck all the line were terribly corroded and could break at any time . Taking it to my mechanic next week to replace all the lines. 9/1/2015

I drive a company truck during the week and make a habit of driving my sierra once a week as well. I was going down the driveway to the main road when the pedal fell to the floor. No brakes whatsoever. I used the emergency brake to come to a safe stop. I looked under the hood to realize that the brake lines were rusted and had blown a hole. This truck is not that old and I do not live in a northern state where salt corrosion is an issue. I baby my truck and keep it up. I later did a search on the web an found out that thousands of others are having this issue as well. This is ridiculous, this is a bad material choice for brake lines. Gmc needs to realize this and recall all of us and install coated, or better yet, braided/poly-covered lines to make sure this never happens again. What if I were traveling at a higher rate of speed and had my family in the car? I can see their stand on this being a maintenance issue, but I have friends with early 80's and 90's model trucks that still have the original brake lines in them, not corroded or rusted, and still work great. Get on the ball gmc and take responsibility for this.

When traveling through an intersection at a green light another vehicle illegally entered the intersection. I saw the vehicle and attempted to stop but when I hit the brakes the pedal went down to the floor and no braking action occurred. I was told I blew a brake line. The car was repaired of the damage from the accident but I had to pay for the brake line repair. After getting the truck back I brought it back to the repair shop for an alignment within a few days. While the repair shop was driving the car in for the alignment a second brake line blew. There is not a recall from gmc and there no reason why the brakes lines should be rusting out and blowing on a car that is well maintained.

Brake line burst when I pumped brake pedal prior to start of trailering a horse trailer. Gmc dealer stated brake lines were rusted through. Dealer had inspected vehicle week before during tune-up and did not notify me of rust or issues with brake and fuel lines rusting in gm trucks. I found reported issues with rusting brake lines in gm trucks per my own research. Brake lines are being replaced at my expense.
