 While backing in my driveway sloped downhill, applied brake peddle to slow before stopping. brake peddle went to the floor. luckily i had mind enough to apply the emergency brake to come to a stop before running through my garage. upon inspection, i noticed fluid running off the frame rail onto driveway. i noticed brake lines in frame rail were corroded bad. called dealer, they say they replace brake lines all the time in these vehicles. they wanted $1100. a local garage replaced all the lines for $800. i am the original owner and take good care of vehicle. is this a class problem? should this be covered under a recall? happy to supply vin if needed, just don't have it with me. *tr

 Tl-the contact owns a 2003 gmc sierra 1500. the contact stated that while driving approximately 30 mph, the brake pedal was depressed and there was no response. in addition, the brake pedal traveled to the floor upon engaging. the vehicle accelerated through an intersection after repeatedly applying the brake pedal. the emergency brake was engaged in order for the vehicle to stop. the vehicle was towed to an independent mechanic who stated the brake lines were completely corroded. the vehicle was in the process of being repaired. there was an investigation associated with nhtsa action number pe10010 (service brakes, hydraulic: power assist: hydraulic: hoses, lines/piping, and fittings). the manufacturer was not made aware of the failure. the approximate failure mileage was 155,000. the vin was not available. pmb

 Dear sirs; we own a 2003 gmc sierra 1500 extra cab truck. it was purchased in june of 2003. it has just over 100,000 miles on it. it has been maintained throughout and garaged. on sunday, august 26, 2012, our son was driving the truck in our neighborhood and the brakes failed without warning. (this vehicle is primarily driven by my husband to work and back daily. no indicator light ever came on.) there were children playing in the street. after avoiding a ball that had rolled down a driveway and into the street, he pressed on the brake and the pedal went to the floor. he then pressed on the emergency brake, the emergency brake did not stop the truck. on his third attempt was able to steer to the curb and throw the truck into park to stop. thankfully, there were no kids in his path. he would not have been able to stop and his life would be altered forever. not to mention our lives and that of an innocent bystander/ child. looking online to see if there have been problems reported, we found the nhtsa has an investigation on this gmc trucks and suv?s. the brakes on this truck were done between 70,000 and 80,000. all pads were replaced, 2 new rotors and 2 rotors were cut. no mention of brake line deterioration, corrosion, or visible problems were brought to our attention at that time. this vehicle is used mainly by my husband who drives it 6 miles one way to work daily. no problems, squeaking, or pedal changes had been noted. we were all really quite shaken by this incident. we had it towed to a dealership for repair. it went there during the labor day holiday thus delaying the repair. we were informed that the brake lines had rotted out. any information or direction will be greatly appreciated. *tr

 The braking system failed when the pedal went to the floor. investigation revealed that the steel brake line had rusted and ruptured. the only precursor to this was noise from the abs unit at low speed. it appears that all of the brake lines are badly corroded and will need to be replaced.

 Main brake line blew while my wife was backing up in a parking lot, the only way to stop was to put the car in park while moving. we had it towed to our local mechanic who had to replace every brake line. the truck only has 68k miles on it. the mechanic said they were very bad and we were lucky to be safe. i cannot believe this issue has not been addressed and recalled by gmc. our bill was an unexpected $1,300. i'm expecting a call back from a district gmc contact monday about the issue. i'm fighting to be reimbursed as this is a known deadly issue and needs to be recalled. how have they not been sued from this problem yet?

 A brake line burst underneath the truck when i applied the brakes with substantial pressure (not enough to engage abs on the dry pavement). was able to swerve to avoid vehicle that cut us off and use emergency brake to slow/stop vehicle in a safe place. all brake lines were severely rusted/corroded and needed to be replaced. fuel lines were replaced as well at the same time, due to severe corrosion.

 I entered my vehicle to drive home and realized that i had no brakes. after looking underneath i realized that my brake lines were rotted and leaking. one line is currently leaking but they are all in very bad condition. i was left with no option but to have the vehicle towed home. i am going to have to replace all the brake lines as even the ones that aren't currently leaking are in very poor condition. it would be unsafe to drive the vehicle without replacing them. i am very fortunate that the failure didn't occur while i was driving at a high speed. when i parked the vehicle the brakes were fine and when i came out 20 minutes later i had absolutely no brakes.

 Luckily there was no accident as i have been teaching my 16 year old daughter to drive. the brakes felt spongy and not as responsive as normal on my way home from work. when i stopped in my driveway, i looked under the vehicle and brake fluid was pouring out of an apparently ruptured line to the back brakes. there was no warning light on. regardless of the miles, this truck is barely 8 years old. a quick internet search shows that this model year and nearby years of the same type of truck have experienced this problem. had this been on a highway trip with all fluid draining out, there certainly would have been an accident.

 Starting at <5k miles the vehicle power train clunked when shifting from 2nd to 3rd gear. now at 70k miles it clunks when shifting between all gears except final drive. the dealership replaced the output shaft on the tranny, then the u-joints, and modified the electrical shift patern. it still clunks. power steering intermittently locks up at slow speed turns, especially when braking. light bulbs burn out almost every three months. had to pay ($486.00) for replacing the intake manifold gasket when vehicle had little over 40k miles. brakes fade and the pedal almost goes to the floor, again intermittent. i have almost caused several accidents due to the steering and brake issues. gmc issued a letter stating this is a normal occurance and will not cause damage. well, it's getting worse in sound and clunking harder during shifting.

 2003 gmc half ton sierra truck. 3 time since 2003 that i've had to take it in for clunking noise felt thru steering wheel. lubed a couple times then replaced the intermediate steering shaft. still no guarantees that it won't happen again. also very hard to steer when braking and brakes don't respond well when applied quickly. the first time the intermediate steering shaft needed attention the truck only had 15,000 miles on it. the second time was 30,000 miles and the last time was 45,000 miles and occured in march 2010.

 Premature failure of brake lines due to accelerated corrosion. all metallic portions of brake lines exhibiting severe corrosion along total length and loss of thickness to the point of failure. have inspected 6 other trucks of same year and model and all exhibited similar degree of corrosion. it is obvious that brake line material of construction is deficient.

 Corroded brake lines on 2003 gm sierra 1500 long box pickup truck. first failure was in january 2009. second failure in february 2010. when truck was inspected in nov. 2009, inspector indicated that gm truck brake lines are a known safety hazard. he looked over mine, but did see evidence of need for immediate repair. truck was bought new in oct. 2003 by me, and now has only 24,500 original miles on it. gm should most definitely be required to recall these vehicles and replace all corrosion-prone brake lines with corrosion-proof ones. there is no greater safety concern than braking. i am taking truck to have all lines replaced at my expense, in the interest of my and others' safety. but, gm should not be allowed to foist junk with massive safety consequences upon consumers and get to walk away from it. the potential here makes the toyota gas pedal problem seem like a trivial joke! *tr
