I own a 2001 GMC Sierra 1500 pickup truck. During early March of this year, my brakes failed due to rust and corrosion on the brake lines. Two of the steel brake lines under the truck were so corroded with rust that the brake fluid ruptured the lines when I applied the brakes, and poured out on the ground. My braked pedal went to the floor. I had zero brakes without warning. It was only by sheer luck that I was traveling very slowly when this occurred, and I was able to stop using the emergency brakes. I was in the town of renovo, and could have killed someone due to this mishap. We live on a mountain, and tow a trailer with horses. This could have been a complete disaster under other circumstances. There was absolutely no warning that the brakes would soon completely fail. It cost over one thousand dollars to replace all of the brake lines on our truck. I have the receipt.
Do not know if it was the front or rear brakes that were lost when driving. Drove carefully to dealership and had a corroded brake line replaced that had a hole or holes in it.
The incident started when the owner of repair service center backed my vehicle out of his garage, upon applying the brakes the entire brake system failed. This failure resulted in the vehicle rolling onto a major roadway. Fortunately, this brake failure did not result in a collision with pedestrians, fixed object, or other vehicles which could have resulted in deaths and injuries. Upon inspection of the brake system, it was discovered that two steel brake lines had ruptured and caused the brake fluid to escape profusely thus brake failure. These two ruptured lines were located next to the abs electro-hydraulic control unit. These steel brake lines had excessive rusting and rotting. The entire steel brake line system showed evidence of severe rusting or rotting. To correct this extremely hazardous and dangerous condition I had the entire steel brake lines replaced. I have secured the original, failed brake lines. I'd appreciate an investigation into this serious condition to prevent potentially dangerous collisions which could result in injuries and/or death. An investigation should also be conducted to determine if there is a possibility of defective material and/or design.
