Brake Fluid Leak problems of the 2006 GMC Sierra 1500

While driving on two lane road,service brake system light flashed, vehicle was hard too slow down and stop. Stopped vehicle and saw brake fluid was leaking from left front wheel brake lines.

I had just replaced the third set of wheel bearnings, asked my wife to hold brake so that I could torque axel nut. When she pushed the brake pedal, I seen brake fluid pouring down the frame of truck. Checked lines all were rusted very bad. Called matheny motors of parkersburg wv. The cost of replacement of lines was quoted at over $1200. 00 I can not express enough how upset I am that this safety item was not made of stainless steel on a vehicle that was at the cost of almost $40,000. 00.

Brake line ruptured due to corrosion. I was leaving a hess station in massachusetts after filling up and when I stepped on the brake before pulling out into traffic the pedal depressed all the way to the floor. I immediately engaged the emergency brake and put the truck into reverse to park the vehicle and investigate the problem. I found a large brake fluid leak under the hood near the base of the steering column where the hard brake line clips to the truck frame. There was a significant amount of corrosion on the brake line. All four (4) brake lines are currently being replaced at the dealership where I bought the vehicle for a cost of ~$2400.

I had towed my boat on the interstate for 2 hours to a lake. Upon reaching the destination I was attempting to launch the boat at the boat ramp. While I was backing my boat trailer into the water I was using the brakes to ease down the ramp. Two family members were in the boat to back it off the trailer once in the water. The pedal suddenly went completely to the floor, I stepped on the emergency brake to stop the truck from rolling into the water. I got out and saw a large puddle of brake fluid under the truck on the drivers side just behind the front wheel area. I got in the truck to see if the brakes could be applied again but went completely to the floor. In order to get the truck, trailer and boat off the ramp I had to put the truck in drive, quickly release the emergency brake and apply the gas to prevent truck from rolling backwards. Upon looking under the hood I found the brake line was rusted in a clip and had ruptured where the left front wheel brake line was retained in a clip on the drivers side frame just next to the steering column. Since it was early enough I was able to get the truck towed to a local mechanic to get the ruptured line replaced. On 5/29/2014 while moving the truck in the driveway the brake line for the right front wheel has now ruptured, upon inspection the rupture is in the exact same location where the brake line is retained in the clip attached to the frame on the front drivers side next to the steering column. At this point I can only assume I will need to replace all the brake lines on the vehicle. If this had happened on the interstate or had to make an emergency stop during the initial incident I would have likely hit someone, lost my boat and injured or killed myself or family members. Brake lines should not rust like this in FL and the loss of one brake line should not eliminate your entire braking system to all four wheels.

The contact owns a 2006 GMC Sierra 1500. The contact stated that while driving 40 mph, he attempted to engage the brakes but the pedal sunk to the floorboard and the brake warning lamp illuminated. The contact mentioned that after inspecting the vehicle he noticed that the brake lines were corroded and leaking brake fluid. The vehicle was not taken to the dealer. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure and current mileage was 61,000.
