Brake Fluid Leak problems of the 2005 GMC Sierra 2500

Taking vehicle out of park brake pedal went all way to floor because steel line ruptured causing massive leakage of brake fluid, rolled out of drive way into street cutting wheel to avoid wreck before could get in neutral and roll to stop !.

While driving to work approaching an intersection the car in front of me signaled to turn right last minute and applied the brakes, I also applied the brakes and the pedal went all the way to the floor. If I didn't have enough following distance I would have crashed right in to the car. I only had about 1/2 inch of brake pedal and drove in low gear very carefully the rest of the short distance to work. When I got out of the truck I saw brake fluid pouring out of the brake lines below the drivers side door and they were completely rusted out. Upon further inspection I realized all my brake lines were rusty on a nine year old vehicle, I never saw anything like this before. I had to get the vehicle towed and repaired at a local garage that charged me $1,547. 61 to replace all the lines and did a horrible job. I had called the GMC dealer I dealt with in the past and they were inundated with recall work and had at least a 2 week wait and another gm dealer that GMC customer service provided me and they were also all booked up with recall work and so I was forced to trust a local shop. This a safety issue that could get people killed, I always have my wife and kids in the truck and it was a death trap. In talking to GMC reps is seems they have no intention to reimburse me for this premature and accelerated rusting condition that could have caused me or someone else their life.

After putting the vehicle in park and proceeding down my driveway, the abs lights began flashing and chiming on the dash. I pushed the brake pedal and it went to the floor. I stopped the vehicle with the emergency brake. I got out of the vehicle and noticed brake fluid dripping underneath the truck. I crawled under the truck and found the left rear brake line had corroded through just above the fuel tank. I called the dealer and he stated this is a known defect from gm. He said I needed all brake lines replaced and gm's new parts had an extra coating to prevent corrosion. It cost me $1100. This type of failure seems way too soon for a truck with 38,000 miles.

Brake pedal went to the floor. Inspection discovered that all the vehicle brake lines were rusted, some to the point of leaking brake fluid.

The hydraulic brake booster's pressure accumulator cracked and /or separated from the hydro-boost assembly during normal vehicle operating conditions. The presence of this crack or fractured surface allowed the hydraulic fluid to leak from the accumulator circuit of the booster assembly. The loss of fluid caused increased steering and braking effort.
