Brake Fluid Leak Problems of GMC Sierra 1500 - part 1

While driving vehicle, complete brake failure occurred. No traffic on road was able to coast to stop without accident. Quick inspection showed severe brake fluid leak. After towing, repair shop found ruptured hydraulic brake line due to corrosion, and multiple other similar weakened spots. All hard lines replaced. Manufacturer declined warranty assistance. Of note, vehicle purchased new, with no heavy duty use, nor high mileage. Original parts in my possession for verification.

I was driving home from work on 421 in eminence, ky. I pushed the brake pedal & I had no brakes right in front of harry hill park. Gm & I are very lucky that no one was killed yesterday. The brake line corroded & leaked the brake fluid, so when I pushed the pedal, it went right to the floor. The vehicle is pretty clean & after checking many blogs & youtube videos this is a very common problem on gm trucks. I checked the recalls on this truck & the tailgate cable is recalled for breaking under load due to corrosion; this could injure somebody, but not as vital compared to the braking system as someone could die in a horrible incident. I would greatly appreciate your attention to this serious matter. Thank you.

The contact owns a 1999 GMC Sierra 1500. While driving approximately 30 mph, the brake pedal traveled to the floor when the pedal was depressed. The vehicle came to a stop and the contact noticed fluid leaking underneath the vehicle. The contact had the vehicle towed to quality Chevrolet (1292 route 9 south old bridge, NJ, 08857; 732-316-2600) where it was diagnosed that the brake line exploded and areas of the braking system were rusted, which caused the braking system to fail. The vehicle's braking system needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 216,000.

When coming to a stoplight, I apply the brakes and the pedal goes down more than it should, but I get stopped. While holding the brake and waiting for the light to change the brake pedal goes slowly to the floor. Next, I pull into a parking lot and get stopped. I put the truck in park an look under the hood at the brake master cylinder, no fluid leaks, then I c look at each wheel, no fluid leaks. I get turned around and head home because I know something is wrong. Driving home the brake pedal is soft. I'm soon home and I park the truck but with the motor still running, I slowly depress the brake pedal, it goes slowly to the floor, next time I depress the brake pedal it goes to the floor in a split second. I get out and inspect under the truck. I see brake fluid leaking from the lines running down the frame right under the drivers door.

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.

While driving at approximately 55 mph on urban road I had to slam on my brakes because of a driver backing out of a driveway in front of me. Brakes initially slowed vehicle then brake pedal went clear to the floor. I quickly engaged parking/emergency brake and was able to stop just in time while simultaneously running off the right side of the road. After inspection leaking brake fluid was observed on left upper frame rail just to the rear of the radiator. After being towed home future inspection revealed a longitudinal fracture on the brake line for the right front wheel. No injuries, minor damage to right side (brush scrapes).

When backing out of a long driveway, the brake pedal suddenly dropped to the floor and brakes did not slow, stop or engage at all. I pumped the brake several times with no response whatsoever and was only able to stop by pulling onto the grass while applying the emergency brake. I found one brake line on the front driver side had rusted through, but none of the others had a leak and the brake fluid was still full. With only one brake line damaged I lost all braking power.

While on state highway and driving the legal limit, I was approaching a green traffic signal. An ambulance with emergency lights was approaching from the cross direction. I applied brakes and without warning brakes pressure completely failed. I had absolute minimal brakes and I went completely through the intersection. It appears to be rusted brake lines. When I apply the brakes, brake fluid squirts out of the front passenger side brake line where it crosses over from the driver's side. I have had all my work done at gm dealers and they never have mentioned this issue. I searched the internet and see multiple reports on this issue and that gm states this is a maintenance issue. I am over 60 and have never had a vehicle where the brake lines needed to be replaced. I was fortunate that my lane was clear or this would have resulted in an accident. It is beyond rational thought as to how gm can say this materials defect is not their problem. Nhtsa should reevaluate this issue and force gm to recall their product before lives are lost.

Slowed down and turned into a parking spot and the abs system kicked in. Did get the pickup stopped and noticed brake fluid leaking by the driver real wheel. Had almost no brakes getting the pickup home. Upon inspection found the rear brake line had ruptured due to corrosion. The abs system has been kicking for no reason before this. Talked to a mechanic and he said there have been a lot of corrosion problems with the 1999 to 2003 gm pickups.

The brakes on my truck failed due to the brake line corrosion. I pushed on my brakes while backing out of my driveway lost all braking power and had my brake . Luckily I was in my driveway when this happened. All of the brake fluid leaked onto the ground, I had my vehicle towed to the dealership and had the brake lines replaced. Upon speaking with the service advisor he said that this was common and that the new brake lines were coated and will not rust. None the less the repair cost and towing cost was quite expensive.

On the morning of Friday August 21, 2015, my wife went to move my 2002 GMC sierra. She pulled out of our driveway and proceeded up-hill about 300-400 feet, and then turned around in a neighbor's driveway, when coming back down the hill she tried to brake to stop in front of our house, but the brakes totally failed without any warning. She then went up a slight hill on the other side of our house, but still couldn't stop, and didn't think to put the truck in park as she slowed. She rolled backwards down the hill and was able to steer into a neighbor's yard where the truck came to rest on a berm. At the time she said there were cars parked on both sides of the street and had a car been coming the opposite direction she would have crashed into it. Had there been pedestrians they could have been hit as well. When I came home that afternoon, I added brake fluid to the reservoir, and then pushed on the brake pedal. I saw a huge stream of fluid pour from below the driver's side door. I looked under the truck and found the brake lines surprisingly corroded. If sudden, immediate loss of brakes without any warning is not cause for a recall I do not know what is.

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.

I had just replaced the third set of wheel bearnings, asked my wife to hold brake so that I could torque axel nut. When she pushed the brake pedal, I seen brake fluid pouring down the frame of truck. Checked lines all were rusted very bad. Called matheny motors of parkersburg wv. The cost of replacement of lines was quoted at over $1200. 00 I can not express enough how upset I am that this safety item was not made of stainless steel on a vehicle that was at the cost of almost $40,000. 00.

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 didnt 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, couldnt 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.

Traveling north on route 28 near chantilly, virginia, a line of cars in front of me came to an abrupt halt. I pressed my brake peddle hard and within three seconds the brake peddle was at the floor. I quickly maneuvered my truck to the right and was able utilize the emergency brake to slow the truck to a stop. Incredibly, my son and I were not injured, we did not hit the line if vehicles in front of us, and were all spared a potentially deadly outcome. After coming to a stop, my son and I inspected our truck and brake fluid was leaking from the left supply line to the rear break. The line had burst due to hard braking and corrosion of the fuel line. We were saved for some reason, however, if this had been on a weekday during commuting hours, the outcome would have been entirely different. The NHTSA should continue to hold gm accountable for this poor engineering (fuel lines) and eventual catastrophic situation that will, or probably already has, happened.

My 16 year old daughter was driving the truck at the time of the failure. She has her temporary license and was driving for the third time. After driving in town and on some rural roads, she started getting too close to other cars at stop lights and stop signs. I began telling her to stop sooner, she said she was trying. It only got worse so we went home. She almost ran into our house as tried to stop in the driveway. Because she is a new driver, she did not realize the brakes were going out. After we got out of the truck I noticed a puddle of fluid forming under the driver side. I determined that it was brake fluid. I raised the hood and had her press on the brake pedal. Brake fluid started spraying out of a brake line near the frame. The brake lines from the master cylinder to the abs module are very rusty along with every other brake line. This truck may be 12 years old and have 87,000 miles but I have always taken very good care of it and it still looks new inside and out. I do not believe a major safety component like the brakes should be failing at this time. Other critical components have warning systems to alert you to possible failures but when there is no way to tell if something critical will fail I believe those parts should be made to last. If the life expectancy of a part is limited, the manufacturer should recommend service at a reasonable interval. My daughter is now scared to death to drive any of our cars because she feels it could happen again. I am just glad I wasn't pulling my 20 foot boat and had to make a panic stop at highway speeds when the line failed. Someone could have got injured or killed I am currently getting quotes to have it repaired. So far I have received prices ranging from $600-1500. I feel gm should cover most to all of these expenses because they used sub-par parts to build a critical component of the brake system.

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.

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.

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!.

Brakes failed in my driveway. Bkake pedal went to the floor with almost no resistance. Fortunately I didn't hit anything. I inspected brake master cylinder & found all fluid had leaked out, area under it was wet with fluid, also, the brake lines under the cylinder looked very rusted.

While driving my vehicle and towing a 4000+ pound boat, my brake petal went to the floor. When I got out of the vehicle, there was brake fluid leaking on the ground. I detached the boat and attempted to see if I could drive the vehicle to the repair facility. There was no braking power available so the vehicle was towed to a repair facility. Repairs were around $900 for a replacement of all the rusted brake lines.

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.

2002 GMC Sierra 1500-brakes went out suddenly as I was turning into a busy intersection. Pedal went right to the floor-no brakes. There was no separate system circuit that brought the truck to a halt, there were no dashboard warning lights engaged, and no brake fluid leak before that would alert me to a failure. Had to use emergency brake to pull over to a safe spot- vehicle needed to be towed to repair facility. Repair facility stated this is a common problem with these vehicles- but there was no recall or safety bulletins issued that they could locate.

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.

Odometer 35,590 miles, truck fluid leaked at the ® rear wheel and the brakes on ® side caught fire. Front brakes were at 6mm and rear brakes were at 1mm. I was driving on the highway. The brakes have been changed 8 times since I bought the truck (every 7,000 - 12,000 miles). Metal to metal with rotors being replaced.

Brake line ruptured due to corrosion. I was leaving a hess station in massachusetts after filling up and when I stepped on the brake before pulling out into traffic the pedal depressed all the way to the floor. I immediately engaged the emergency brake and put the truck into reverse to park the vehicle and investigate the problem. I found a large brake fluid leak under the hood near the base of the steering column where the hard brake line clips to the truck frame. There was a significant amount of corrosion on the brake line. All four (4) brake lines are currently being replaced at the dealership where I bought the vehicle for a cost of ~$2400.

I had towed my boat on the interstate for 2 hours to a lake. Upon reaching the destination I was attempting to launch the boat at the boat ramp. While I was backing my boat trailer into the water I was using the brakes to ease down the ramp. Two family members were in the boat to back it off the trailer once in the water. The pedal suddenly went completely to the floor, I stepped on the emergency brake to stop the truck from rolling into the water. I got out and saw a large puddle of brake fluid under the truck on the drivers side just behind the front wheel area. I got in the truck to see if the brakes could be applied again but went completely to the floor. In order to get the truck, trailer and boat off the ramp I had to put the truck in drive, quickly release the emergency brake and apply the gas to prevent truck from rolling backwards. Upon looking under the hood I found the brake line was rusted in a clip and had ruptured where the left front wheel brake line was retained in a clip on the drivers side frame just next to the steering column. Since it was early enough I was able to get the truck towed to a local mechanic to get the ruptured line replaced. On 5/29/2014 while moving the truck in the driveway the brake line for the right front wheel has now ruptured, upon inspection the rupture is in the exact same location where the brake line is retained in the clip attached to the frame on the front drivers side next to the steering column. At this point I can only assume I will need to replace all the brake lines on the vehicle. If this had happened on the interstate or had to make an emergency stop during the initial incident I would have likely hit someone, lost my boat and injured or killed myself or family members. Brake lines should not rust like this in FL and the loss of one brake line should not eliminate your entire braking system to all four wheels.

The contact owns a 2006 GMC Sierra 1500. The contact stated that while driving 40 mph, he attempted to engage the brakes but the pedal sunk to the floorboard and the brake warning lamp illuminated. The contact mentioned that after inspecting the vehicle he noticed that the brake lines were corroded and leaking brake fluid. The vehicle was not taken to the dealer. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure and current mileage was 61,000.

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!.
