I reacted by hitting me brakes and while I was slowing down my brake petal suddenly went all the way down to the floor. I was traveling approx 5-10 mph when I hit the vehicle in front of me. After moving our vehicles from the road, I discovered brake fluid dripping from under my engine. I inspected the brake fluid reservoir and the master cylinder. . . Both looked normal. I got under the front of my truck and I could see brake fluid had been sprayed all over the lower front of the engine and front bumper. I could see that the brake lines were very rusty. Before the accident there wasn't any indication that I was having problems with my brakes. I seems as though the brake line just failed. I was traveling on a local road in a straight line approx 30-35 mph when the accident occurred.

Was able to make it home with brake peddle hitting floor and brake line failure light and audio warning. Approx. One month earlier, parking brake line, rusted through and broke. Upon searching for brake line leak, I was frightened on how rusted out all the brakes lines are,.

I have had 2 incidents with my 02 GMC Yukon where the brake lines have failed due to early and unexpected/unreasonable corrosion where they failed without warning almost caused serious accidents. The first incident occurred with about 76,000 miles on the car and I was driving on the highway and applied the brakes as I approached the exit ramp and the pedal went straight to the floor without the vehicle stopping. With my family in the car I drifted past the exit and approximately another 1 mile before finally coming to a stop on the shoulder. After getting the car towed to a local mechanic, they informed me that the rear brake lines rusted through and this was a common problem they see on gm vehicles. They were surprised I was not in a serious accident and I paid $500 to have the replacement lines fabricated. About a year later with about 85,000 miles on the vehicle and again without warning as my wife was driving my children across a bridge and attempted to brake and again the pedal went straight down to the floor not stopping the vehicle and she held down the horn to warn pedestrians and other cars. The vehicle finally stopped after running 2 red lights. The mechanic indicated that all the lines coming out of the master cylinder/booster were rusted through and brake fluid was pouring out. Again having to fabricate and replace all the lines out of the master cylinder was expensive, this time costing $1,500. The NHTSA needs to do a full investigation of this problem as I have heard many times that this is a faulty design and extremely dangerous requiring a recall. I take good care of my cars, have the undercarriage cleaned frequently and ask my mechanic to inspect everything on the car on a bi-annual basis and these incidents happen without warning. I hope gm will reimburse all those like me who spent thousands fixing the vehicle after a very dangerous situation.

I started vehicle, depressed the brake pedal, I then placed the shifter into reverse and proceeded to drive when I realized the vehicle wasnt stopping as usual. I then put the shifter into drive and parked it . I got out of the vehicle and noticed alot of fluid (on the drivers side) all over the ground. I called a tow truck to have it moved to a mechanics location for further inspection. The main (corroded) brake line burst causing fluid to leak everywhere and creating a potetially serious life threatening driving hazard ( brake failure) had I not parked the vehicle it would have been a different ending. . . . This needs to investigated immediately.

The brakes recently failed on our 2002 GMC Yukon xl 1500 4wd SUV. While descending a moderately steep hill on our street, my wife depressed the brake pedal to slow the vehicle, and the pedal went all of the way to the floor. Thankfully, she was able to coast the vehicle up the next hill and bring it to a stop. Inspection revealed brake fluid had leaked from a highly corroded brake line on the underside of the vehicle, below the driver's seat. Three other adjacent brake lines were also similarly corroded. Upon contacting the nearest gm dealer (tom gill Chevrolet, florence, ky), the service agent informed me "that's not uncommon in a 9-year old vehicle. " four almost completely rusted brake lines, in just 8 years? that ridiculous! I have a 16-year-old Toyota in the driveway that doesn't have this problem, and I shouldn't expect to have it with my much more expensive and far newer american made SUV. Tom gill service refused to give me an estimate of repair, stating I would have to have it towed the 17 miles to the dealership, with a "we're competitive--we'll give you a competitive price. " comforting. A few more calls to local shops revealed an estimate of between $850-1,100 for removal and replacement of all four lines. I ended-up spending 22 hours pulling-out the old lines and bending/flaring/installing entirely new front lines myself. Last week I learned I'm not alone--a wcpo news report revealed this is problematic with gm trucks/suvs, with gm deflecting blame to "salt brine. " after all of these years, american manufacturers are still taking shortcuts and canning ethics. . . Toyota will continue to win market share as long as this crap continues. I'm angry because it's putting our families at risk. No one got hurt this time, at least not in my family, but the potential is certainly there. I think gm should be held accountable, and I am holding onto the corroded brake lines as evidence in the event of a future recall. I'd also like those 22 hours back.

Driving from tampa to orlando in my 2002 GMC Yukon with trailer in tow. Brakes went to floor while had to use emergency brake. I was tow home by aaa no fluid in reservoir filled it up. Saw fluid leaking under drivers door look with flashlight and saw cluster of lines corroded leaking from a round device and running down the rail toward back. About two ft. Long. I think they are the metal brake lines and their failure seems like a defect in material as I think they should be made of a harder or more lasting stainless steel or something as brakes are the most important device on a vehicle. I now feel for the safety of my family GMC said improper maintenance. I think GMC should take care of their faulty defective brake lines before someone is killed or maybe they have already.

I recently experienced a total brake failure after driving to the grocery store today. Yesterday, I realized that to stop, I had to press the brake pedal almost all the way to the floor. I knew something was wrong because my brakes had been working just fine. Today I noticed the same problem and reported it to my boyfriend, who conducted a visual inspection at the brake lines and underneath the driver side seat, brake fluid was leaking out rapidly and was puddling underneath the vehicle. Had I not stopped, I would have been in a serious accident. As a result, I can not drive my vehicle because the brakes are no longer working. I have a 2002 GMC Yukon denali xl.
