2004 GMC Yukon Owner Comments

problem #4

Oct 292011

Yukon 4WD 8-cyl

  • 64,200 miles


The subject vehicle had recently been parked after towing a 29 foot long travel trailer. It had sat for approximately two weeks since we last used it. During the 2011 30 October snow storm in pa, I went to pick it up to use it. I started down the driveway and went to apply the brakes and the brake pedal traveled to the floor. All of the antilock and brake warning lights appeared on the dash. I was able to stop the vehicle and back it back the driveway and park it. We later called aaa and had it towed to a local Chevy dealer. They diagnosed the problem and let us know that they had found a brake line that burst due to corrosion. This brake line is almost directly under the power brake booster assembly and is somewhat hidden from view. It lies atop the frame in this area and according to the dealer had corroded. According to the dealer they had to fabricate a replacement brake line and were able to replace it. They further indicated they looked at the other brake lines and did not see any further indication of corrosion. I have driven the GMC for about ten miles since the repair and the brakes appear to be back to normal. Let me add this, I have owned 15 different vehicles in my life and not one has had to have a steel brake line replaced. This is the first. Just like the other GM owners, when these lines fail the braking ability to stop this two ton vehicle is almost non-existent I am very thankful this line did not fail while towing the 29 foot travel trailer.

Brake pedal effort is excessive, resulting in several near misses due to inability to stop rapidly. Have notified dealer(s) several times, and they have stated that brakes were okay. I personally feel that brake pads and/or rotors were too small for weight of the truck.

The contact owns a 2004 GMC Yukon. While driving at 25 mph the contact engaged the brakes and the vehicle would not stop and caused it to crash into the rear of another vehicle. The failure mileage was 70,000. Between the two vehicles, four people sustained minor injuries. This was the second time the brakes failed. The vehicle was not drivable and will not be repaired. The current and failure mileage were 70,000.

The consumer would have to depress the brake pedal hard to the floor for vehicle deceleration. This would cause extended stopping distance. The dealership was notified, but did not resolve the problem. The cause was not determined. Please provide any additional information.
