The first occurance was a year ago when driving to play golf. When I was about one mile from the course, the brake pedal went to the floor when depressed. I was able to make to the course and called a tow truck. The repair was made by the local dealer. He asked me if I lived at the coast due to the corrosion found on the brake line. I do not live near the coast and the vehicle is garage kept with only 102,000 miles on it. Most recently while driving in town, I depressed the brake pedal and the same thing happened. It went to the floor and was very slow to stop. In my estimation, this is very poor workmanship on behalf of general motors! I hope that no person has been killed due to this defect.

On several occasions when applying brakes to stop the yukon it fails to stop and then ABS kicks in causing brake pedal to vibrate and loss of pressure in brake pedal then truck does not stop it slides. I have replaced master cylinder did not help, truck needs all new brake lines due to rust. I have quickly move around cars to prevent a accident, due to this brake failure. Since I am in south florida gm won't fix this known manufacture defect because sf is not a "salt belt" state, but I live on the beach and the salt water has started to have a major impact just like the northern states on these faulty brake lines. The break lines are covered in rust and this is a major safety concern and gm should fix all vehicles with this known defect not just some. This 2002 yukon is sle with a 5.3l VIN z.

Today my wife took our very good condition well maintained garage kept 2002 gmc yukon to dunkin donuts to get coffee. She was stopped in the drive thru line when she heard an air sound as her foot on the brake went to the floor, she was able to limp home, about a mile, by pumping the brakes and it was early so nobody was on the road. Indeed the brake line above the fuel tank was broken, I know because I dropped the fuel tank. We were lucky she didn't get in an accident and we weren't on vacation far away. I also flush out the brake lines with new fluid every time I change the brake pads. I know a lot of people with cars much older than ours and no brake line issues. We also had brake line issues with a 2003 gmc yukon xl. Something needs to be done about this since this is not normal. And this happened when she was stopped in line, not after a hard emergency braking.

While braking from a speed of 45 MPH to stop for a traffic signal, the brakes failed. I was able to engage the parking brake to stop the vehicle several feet past the stop line. Fortunately, no accident resulted from this incident. The vehicle was taken to a local shop where they discovered that the brake line had failed at a 90 degree bend due to corrosion. Upon research, the shop said that a service bulletin had been issued stating that the entire brake line would need to be replaced because it is subject to corrosion at every point where there is a mounting bracket attaching it to the vehicle.

After a morning of driving around town doing errands I returned home with groceries. While there I decided to swap out my reverse light bulbs before driving my son to baseball practice. While making this maintenance repair the brakes on my truck failed completely. The brakes sank all the way to the floor. Fortunately I was able to keep the truck from backing into the cars parked across the street behind me..and that I had not gone right out to drive my son to baseball. When I got out to inspect the brake lines had completely imploded and brake fluid was leaking everywhere. After having it towed to a repair shop I was told my brakes had completely rusted out.

Abs and brake light dashboard indicator light activates after any rain or underside of car becoming wet due to road moisture. Water, salt, and other environmental contaminants cause various components of the ABS to fail triggering the ABS and/or brake failure light on dashboard to turn on. Various gm dealer recommend replacement of the electronic brake control module and brake pressure valve in addition to associated connection hardware. Estimated cost of parts is in excess of $2k and labor is $500. No assurances are given this will fix problem. Previous recalls by gm, vehicle owner complaints, internet websites, and internet forums address ongoing ABS and brake light system problems due to exposure to water, moisture, and other environmental elements; indicates the life cycle of gm ABS and brake systems are severely reduced in comparison to all other makes and model cars/trucks with ABS systems. The number one the federal safety agency complaint issue remains the ABS brake system on gmc yukons produced from 2000 to 2006. There have been various the federal safety agency/gmc recall notices that address partial fixes to the ABS but none requiring the recall of the complete ABS system itself. Failure of the ABS will result in brake lockup at any speed. The failure of the ABS system to function properly because gm did not design the system for it's operating environment has created a dangerous expensive problem for gmc yukon owner/operators.

Driving on rt 22 in nj at 55mph when traffic light changed to red and stepped on brakes and the pedal went all the way to the floor. The car only slowed slightly and ended up in the middle of the intersection before it stopped. Lucky that it was in the mid afternoon and the traffic was light because the distance to stop was about 5 times the normal distance and had to use emergency brake to stop the car. There was a sudden failure of the brake line due to corrosion, I had the car inspected by a mechanic, causing the pressure to drop in the system. After the incident I went online and found that this is a problem for years with this make and model. I am a surgeon and find it worrisome that this agency has not recalled this defect and that gmc has not notified consumers of the possibility so they can have the brake lines changed.

On april 19, 2013 I was driving with my daughter in wilmington de to the amtrak station. Approximately 3 blocks away from arriving, my brakes failed as I attempted to stop at a traffic light. The brake pedal went completely to the floor. As there was almost no stopping power left, I pulled the emergency brake and downshifted to low, and partially slowed, stopped in the last section of the intersection. I pulled to the side of the road and had the car towed to my auto shop. My mechanic told me the front brake lines were rusted to the point of causing a major brake fluid loss. He replaced the brake lines with stainless steel tubing and fittings. I had to pay $485.35 to make this repair. I now know the federal safety agency is investigating these dangerous and defective gmc brake lines in the 'rust states' including my home in pennsylvania. The us govt should force gmc to recall these inferior corrosive brake lines to avoid the chance for fatal accidents, and gmc should reimburse me for my costs. I will now file a second the federal safety agency incident report for a second "rear" brake line failure in oct 2013. -[xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
