Brake Fluid Leak problems of the 2003 GMC Sierra 1500

Started my vehicle applied the brake to shift to drive and the brake pedal went to the floor. I got out of the vehicle and there was a puddle of brake fluid on the ground on the driver side under where the drivers seat is. There was brake fluid dripping from a rusted brake line. I'm lucky this happened when the vehicle was stopped and not while I needed stop because it was a complete loss of brakes.

I was towing my 33' travel trailer with my very well maintained 2003 GMC Sierra 1500 pick up truck. After a four and a half hour trip on the interstate highway doing 65 mph, I arrived at my campground. As I was backing my trailer into my camp site, my brake pedal went to the floor and my dashboard lit up with warning lights. I had complete brake failure. I put the truck in park and got out to look under the truck. Right below the driver seat, brake fluid was pouring out of the brake line which had burst open. I had no brakes. Thank god this happened while I was backing the trailer in at 2 mph. Minutes prior to this I was going 65 mph on the highway, towing a 33' trailer. I shutter to think what could have happened if this line burst while at highway speeds. My wife and I were freaked out for days thinking about what could have happened. We had to have the truck towed to a repair shop and endure a very expensive replacement of all the brake lines, which were completely corroded. While the truck was being fixed I did some research on this problem and found that there were many, many, complaints about this exact same problem concerning 1999 - 2003 GMC and chevy pick up trucks and other models. Gm claims that you would still have some brakes because there are separate brake lines to the front and rear brakes. This is true, but I lost so much fluid, so fast, I had no brakes. Does someone always have to die before they force a recall? there are so many complaints on this matter and I know there is an on going investigation by the NHTSA. Enough investigating, force the recall before someone dies if they haven't already.

On 8/9/15 at approximately 3:25pm an individual pull out in front of me. When I applied the brakes to keep from hitting him, the brake pedal went all the way to the floor board. I noticed at the time the "service brake system" indication was showing on the driver cid. I was able to drive the truck to a safe location and park it. I looked under the vehicle and noticed brake fluid on the ground under the right front wheel. The tow truck driver also checked and noticed brake fluid shooting up when the hood was up. At that time, he noticed the right front brake line had rusted through. The truck was then towed to cunningham GMC in springfield, TN.

The contact owns a 2003 GMC Sierra 1500. While driving approximately 40 mph, the brake pedal was depressed and traveled to the floorboard. The contact noticed brake fluid leaking from the vehicle. In addition, the rear seat belt latch failed to function. The vehicle was taken to a dealer where it was diagnosed that the brake line needed to be repaired. The vehicle was repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 144,917.

Driving down middlebelt road coming up to a red light I hit the brakes and the brake pedal went to floor, truck finally came to stop, looked under hood and could see brake fluid leaking out of right front brake line.

During major snow fall after new year 2014, upon arriving home from work, with my wife and another passenger, I attempted to stop and my brake pedal sunk to the floor, nothing, no brakes. I nearly drove through garage door. I had to cut the wheel and punch the gas to perform a "half doughnut" to avoid hitting my house. Had there not been signifigant snow on the ground, this maneuver would have been impossible. The following day while navigating vehicle into garage, we had an incident , causing minor damage to truck & garage. Upon inspection, I discovered the steel brake lines were extremely fragile do to rust. 2 lines from proportioning valve to abs unit, & 2 lines from abs unit to front wheels deteriorated under body near chasis. One of the lines from prop valve to abs failed, leaking brake fluid. I went to abeloff GMC where I was informed only lines from prop valve to abs where available. I purchased and changed them. However, as I suspected the front lines would leak due to the fact they would be disturbed while changing prop v. To abs lines. They failed before I got the truck out of the garage, causing a minor accident in garage . I then found a company online, classic tube, which provided me with a kit containing all brake lines made from stainless steel. So, not only could we have quite possibly been killed, but I now have [2] extra brake lines that cost me $125. 00 that I don't need. Gm could at least had the decency to make all the lines availeable. I also discovered that this problem is not uncommon. Had these brakes failed a few minutes earlier, say on rte 80 w in PA, it could have been tragic for me, my wife ,my passenger, and anyone in the way!.

I put my truck in reverse to back out of the shop and my brake pedal went to the floor. I quickly threw it in park an turned the truck off. I then pushed the brake pedal again and it again went to the floor and I heard brake fluid squirting out. I put the truck on the lift and raised it up to inspect the issue. After doing so I found very rusted brake lines and components. After research I found this to be a very common issue with these trucks. Seems maybe gm should be fixing the issue. I wouldn't think a truck less than 10 years old should have such rusted brake parts. Especially since the exhaust is made from stainless, why not brake lines?.

Tl- the contact owns a 2003 general motor Sierra 1500 hd. The contact stated while driving 55 miles per hour, the vehicle would suddenly come to a complete stop until the brakes were applied repeatedly. The contact noticed the vehicle was leaking break fluid which led to the discovery of a rusting brake line. The vehicle was not taken to the dealer, and the manufacturer was not contacted. The failure and current mileage was 34,000. Rvk.

When attempting to stop truck, brake pedal faded to floor. Upon inspection, the brake lines exhibited severe corrosion and rusted thru allowing fluid to leak out. The truck has less than 90,000 miles.

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.

On September 29, 2010, I was driving my truck on rt. 66 west approaching linden va. At approximately 65 mph when traffic began to stop abruptly because of roadwork. I was in the left lane and applied my brakes. At this time my brake pedal went to the floor. I had begun my stop far enough away from traffic ahead of me that I was able to slow down without hitting anyone in front of me. I moved my truck over to the right shoulder, then onto the ramp for the linden va. Exit and then parked on the shoulder there. When I got out of the truck I found a puddle of brake fluid quickly forming under my truck, below the left frame rail behind the left front wheel. When I looked up to see where the fluid was coming from, I found the leak coming from a bundle or four brake lines, that were heavily corroded, that ran beside the frame rail. At this time I made arrangements to have the truck towed to my residence. At the time I was towing a single axle utility trailer. The truck has not yet been repaired. This truck is a 2003 GMC Sierra 1500 hd crew cab short bed, 8600 gvw. It is nearly identical in equipment to a 2500 hd crew cab short bed. I purchased this vehicle new.
