Brake Hoses, Lines/piping, And Fittings problems of the 2000 GMC Yukon

Rusty brake lines resulting in complete brake failure. Thankfully the vehicle was stationary at the time, so no accident as a result of this failure.

After getting cut off and having to make a panic stop the brake lines in my truck burst causing the pedal to go to the ground and offer no braking power. I then tried the emergency brake which also didnt work due to the burst lines. I was finally able to steer into the shoulder of the road and put the transmission into a lower gear to slow down before putting it into park at 25 mph and skidding to a stop. After getting home and doing research and learned of your investigation. Something needs to be done as I almost died.

The contact owns a 2000 GMC Yukon. The contact stated that while driving approximately 5 mph, the brakes failed to engage when depressed and the brake pedal abnormally traveled to the floor board. The contact mentioned that the abs system activated independently . The vehicle was taken to a dealer where it was discovered that the brake line was corroded. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure and current mileage was 157,500. Updated 02/24/lj the consumer stated the recalls were never done. The recalls were falsely reported as being complete. The front bearing assemblies had to be replaced, at the consumers expense. Updated 02/25/14.

Applied pressure to brake pedal and it went to the floor. Took the car to a midas muffler garage as it was closest for diagnosis and found that the brake line had rusted away. It had rusted out at the point where it goes over the top of the gas tank. They told me that they have seen this many times on these cars.

Coming to a stop and brake pedal went to floor. . . . My vehicle then rolled into intersection causing an accident when the other vehicle collided with the front of my vehicle. Further investigation found brake line burst. To remedy situation I replaced all brake lines.

My mechanic advised me that the brake lines are rusted and would cost @ $3000 to replace. Yukon will not pass PA inspection and is dangerous to drive.

Brake line from abs module to rear brakes failed due to corrosion.

Driving on south on route 95 through connecticut at approximately 65 mph on 17aug12. Had to stop suddenly due to traffic incident ahead. Applied brakes but line burst and peddle went to floor. Car would not stop but fortunately was able to move into breakdown lane to allow longer stopping distance. Narrowly avoided rear ending car in front of me at high speed. Brought vehicle to dealer for repair. They found the left rear brake line had ruptured due to rust. Dealer replaced 40" of brake line. A similar event occurred during may of 2013 on route 3 in massachusetts. A collision was narrowly avoided.

While driving vehicle and towing boat depressed brake pedal and it went to the floor. There was no prior warning that brakes were about to fail. Used emergency brake to stop vehicle. After getting vehicle to secure location, observed steady stream of brake fluid running onto ground from under drivers side door. Apparently rotten brake lines that run from front of vehicle to rear failed.

Brake line on driver side rotted causing rapid loss of fluid.

After no warning (lights, chimes or alarms), applied brakes and pedal went to the floor. No brakes. Luckily it was very early and nobody was on the road when I blew through a stop sign intersection. Local dealer says aluminum brake lines were severely corroded and had ruptured. Nearly $2000 to replace aluminum brake lines with steel. Everyone knows when you place different metals in contact where they can get wet, you will get electro-chemical corrosion of the weaker metal, in this case, aluminum. Thats why boats use aliminum and zinc as a sacrificial metal in marine environments - to protect the engine from corrosing. This is surely an engineering flaw. On my Yukon, the auminum brake lines are attached to the steel frame underneath the vehicle where they are sure to get wet anytime it rains, thus guaranteeing the weaker aluminum metal will corrode. I have a 45-year-old mustang with original brake lines (steel) and no corrosion. 10 years is absolutely unnacceptable for brake lines to be corroded to the point of catastrophic brake failure through normal use and normal weather. I live in maryland, not alaska. Our weather is average. There should be a recall and I should be reimbursed.

Rigid brake line corroded and failed leading to greatly diminished braking capacity. This poses a safety hazard. I was told by the gm dealer I brought the truck to that all of the brake lines are severely corroded and need to be replaced.

Dt: the contact owns a 2000 GMC Yukon. The consumer experienced total brake failure at a low speed on a busy intersection. The dealership later found that the stainless brake lines rusted through. There was no prior warning. The road condition was pavement on a dry road. The failure occurred under normal braking. The consumer had the repair performed on her vehicle. This is the first time she has experienced braking problems. Repair invoices are available. The vehicle had to be towed to the dealership.
