2004 GMC Sierra 1500: brake failure

Filed May 26, 2020 · Brakes, Fuel system · KY

Corroded brake lines. This has been reported previously. I was driving down rural road getting ready to turn in my driveway when my brakes gave out. I was lucky enough to be able to get it into the gravel driveway without killing someone. When I looked underneath to find the brake lines were corroded and one had burst. I had part of the line fixed with copper tubing. I have since had 2 more lines burst. As well as a fuel line leak. This has become frustrating.*dt

On january 24, 2017 traveling on pa turnpike at posted speed limit of 70mph, when I applied brakes to slow when approaching slower vehicles. Brake pedal went to the floor and vehicle almost ran into the rear of slower vehicles. Metal brake line ruptured above left front wheel. When inspected, all brake lines exhibited extreme rust/corrosion to the point of flaking and thinning. This is an extreme safety issue which could have resulted in a major collision and would have injured or killed occupants. This problem is a major known safety defect and needs to be remedied by gm.

As I approached a major intersection the traffic light turned yellow and I applied the brakes preparing to stop. The brakes failed and the petal went to the floor. The truck rolled halfway into the intersection before I was able to step on the emergency brake and fully stop the truck. The dashboard flashed on indicating "repair brakes"...a little too late to help. If I had a vehicle in front of me , I would have hit it and possible injuries would have resulted. I had my daughter in the front passenger seat and was glad for seat belts.

I was driving on my way home from a restaurant, just about 4 blocks from my home I applied my brakes and anti lock brakes was acting up and I pressed a little hard to stop before a stop light and the pedal went right to the floor. I had to drive very slow to get my truck to my home as I have no brakes. By the time I parked my parking spot I got out and opened my hood to look at the brake drum didn't see anything and proceeded to look underneath my truck and found a puddle of brake fluid just under drivers side bottom. I was amazed to see that and it looked so rusted, couldn't pinpoint where the leak is coming from on the lines it was all soaked with the fluid. Right now I feel that the gm corporation should replace all the lines at a no cost to me. They should not have put an inferior product on the truck and it is dangerous they can have someone killed if the brakes fail on a higher speed !!! They tricked the customer into buying a quality made trucks and its not! It is made of cheap cheap cheap quality parts that I spend on with my money when I brought the sierra 1500 new from a gm dealer in july 2004 mileage at the time happened around 118385.

Brake failure! Brake line rusted through allowing fluid to leak out. I do not understand why they have safety belts, air bags, safety glass, and many other safety features on cars and trucks but do not make it mandatory that all brake components (lines) are not made of stainless steel tubing! Being unable to stop in an emergency because of brake failure can result in many catastrophic accidents and unnecessary deaths or injuries!

Driving into the village, had to stop for someone making a left turn, and the brake pedal went to the floor. Complete braking failure. No accident, I was able to pull off to the right, but real scary, my son was with me. Got the truck home and now all the brake fluid ran down the drive way. Looks like gm went cheap again, the brake lines are horribly rusted and the fluid is leaking from an area just under the drivers seat.

While driving in the city my brake pedal went all the way to the floor and I had minimal braking power. I was able to stop the vehicle safely but the brakes lines are completely gone. They are all rusted and have several holes in them and must be replaced.

Coming up driveway in 2004 gmc sierra pickup truck and went to apply the brakes and the pedal went straight to the floor - no brakes. Had to push emergency brake to stop truck. After getting out of the truck, saw fluid leaking out beneath truck under driver's side door. Looked under vehicle and found brake lines had rusted completely through and brake fluid was draining out.

Brakes failed without warning and vehicle would not stop. Pulling into car wash and when brakes were applied the pedal went to the floor and the truck went out the other side of the car wash. Could have been very dangerous as I pull an equipment trailer with 7000 pounds on it and it would have been impossible to stop. I will never own a gm product again. This is unacceptable.
