Driving to work one day, a car in front of me suddenly stopped to turn left. I hit my brakes and felt a "pop" and the brake peddle went straight to the floor, no brakes. I was travelling about 55 mph so at that point, I am a 55 mph spear on wheels. I swerved to the right and drove across someones driveway and through their yard. This weekend was the city wide garage sales, and thankfully, these folks were not having a sale in their driveway or yard, or else this could have been a terrible accident. The only rust issue with this truck is the brake lines and fuel lines. If your lines rust before your body rust, then I feel there is a serious design flaw. If it was something else rusting then it wouldn't be as big of a deal. But when you are talking brake lines, it is just a matter of time before this flaw causes another catastrophic brake failure, leading to an accident involving serious injury or death. A 10 year old truck should not have this problem. I have owned vehicles that were 15, 20 years old and have never had to replace brake lines. Someones life is worth so much more than a cheaply made brake line.

Arriving at my RV site in alabama from upper michigan a neighbor saw something leaking from near the left front tire of my pickup. Upon determining it was diesel I immediately drove to the local chevy dealer. They said due to the condition of the lines they all be replaced. Next day I was asked to come to the garage to look at the brake lines as they could not move any to get proper routing of the fuel lines. The lines attaching to the abs modulator, total of 6, looked like you could crumble them with your hand so all were replaced as well. I pull a 33 foot fifth wheel and consider we were extremely fortunate nothing happened on the road.

The contact owns a 2004 GMC Sierra 2500. The contact stated that the brake failed to engage while attempting to apply the brake pedal while driving 35 mph. The vehicle was towed to a local mechanic for inspection that confirmed that the brake lines were corroded. The vehicle was not repaired. The VIN was not available. The manufacturer was not made aware of the failure. The failure and current mileage was 98,000.
Brakes failed to stop vehicle at intersection/stoplight. Brake pedal went to floor and stayed there. Determined that rust through in brake line at driver side of frame, under driver seat, had allowed fluid loss.
The vehicle was parked on a 35-40 degree sloped driveway. Got in, stepped on brake,started vehicle, released emergency brake, shift into reverse, and brake pedal went to the floor, with truck rolling backwards. Wheel was turned, and truck hit a side of retaining wall. It did not roll back excessively fast, but it could not stop in time to avoid hitting the wall. Found badly corroded brake lines. One had ruptured right behind the driver's front wheel fender well.

I had stopped at a gas station and when I left I was going approximately 35 miles per hour when I put pressure on the brakes and the brake lines ruptured . Was able to get to a repair shop and they said that the lines had rusted through. All lines had to be changed,.
When attempting to stop, the truck began to stop and then all of a sudden the brake pedal went to the floor. At this point there were no brakes at all. Thankfully no one was in front of me so I was able to coast until the vehicle slowed, and then use the e-brake to slow down enough to turn. Upon further inspection, a brake line had broken.
While traveling on the PA turnpike at approx. 60 mph, traffic suddenly slowed in front of me. I was pulling our 30 fifth wheel camper at the time. I applied the brake hard had a split second of braking action and then the brake pedal went to the floor. I was able to use the manual trailer brake control to slow the truck some, swerved into the left lane missing the car in front of me by inches and the car to the left of me swerved into the far left lane to avoid hitting me. (three lane highway) I managed to drive the truck to a rest area about a mile down the road using both the trailer brakes and the truck emergency brakes. The cause of the brake failure was that the brake line located under the drivers area had rusted through and ruptured.
The contact owns a 2004 GMC Sierra 2500 hd. The contact stated that while driving 40 mph, he applied the brakes but the vehicle did not respond. He continued applying pressure until the pedal touched the floorboard and finally, the vehicle came to a stop. The vehicle was taken to a dealer for diagnosis and the contact was informed that the steel brake lines exhibited massive corrosion and were leaking. The vehicle was taken to a different dealer where the repair was completed. The manufacturer was notified of the failure. The failure and current mileage was 80,000.
I have a 2006 GMC Sierra 2500 hd on 7/24/2013 the truck was having tires installed at a local store. They truck was brought in for a wheel alignment service by a mechanic . The mechanic showed the leak and the corrosion on the brake lines above the I beam. They said to call the dealership in town. I called my insurance company to tow the 2006 GMC to the dealership. After the dealership discovered the problem with the rusted lines they asked for $ 1400. 00 for replacing the rusted lines.
My brake lines rusted at the rear of the lt front wheel splash area. This vehicle has low miles for the year and was not driven in salt or deice. The brake line should not need to be replaced at this time with so much service life left. I was lucky, the brake line burst in my driveway.
Rusty brake lines on 2004 GMC 2500hd sierra. Almost caused me to have an accident because the brake petal went to the floor immediately when the brake line burst. I have pictures of the old rusted brake lines if you would like to see the pictures. Since it seems to be a wide spread problem on gm pickup trucks from researching it on the internet, I'm curious to know when they are going to recall them? just saw on the news where there is a government recall on 2005-2009 Subaru's for the same problem. It cost $1290. 00 to repair all the brake lines.
The contact owns a 2003 GMC Sierra 2500 hd. The contact stated that while driving 30 mph, he attempted to decelerate and the brake pedal went all the way to the floor. The vehicle was taken to a private mechanic who inspected the brakes and noticed there was a hole in the brake line that caused a leak. The mechanic stated that he needed to replace the entire brake line. The manufacturer was not notified. The failure mileage was 99,075. The VIN was not available.
I was on my way to work and I lost all brakes,took it to a mechanic ,he informed me it was rusted brake lines.
I purchased the 2006 2500hd diesel pickup new. The truck has had poor braking since new and the dealer has always said it functions normally. I have had the dealer do all the maintenance on the truck other than oil and filter changes. The undercarriage of the truck including all lines, brakes rotors, hubs¦ has been rusting since new. The underside of the truck looks like a 20 year old plow truck. On 12-6-2012 I was driving on the highway in traffic and the experienced a complete brake failure. Some how I did not hit anything and was able to get to the shoulder and coast to a stop (very lucky in n. J. Traffic). The brake lines blew the truck was towed back to the dealer and they find the lines are gone as well as the rotors that they replaced about 2 years ago. The pads are still in great shape but the rotors are rusted beyond usability. Looking into this I find I am not alone and would like to know if I can get info on the issue including, is the problem fixed in the new trucks and is compensation available as the truck is on its way to the rust grave yard with the sheet metal rusting from the underside also.

Rotted out brake lines @ 118,000 miles . Should be a recall . No accident but was pulling my boat at time of failure. Could have been a very bad accident . Just finished changing all the brake lines what a job. Between this n the injectors this truck was a poor value. All done with gm had too many problems with their trucks with no support from gm or it's dealers. Lost lifetime customer.
Complete brake failure, when brake line blew out while trying to stop. Prior to hitting car in front, swerved into left turn lane and applied emergency brake.
The contact owns a 2003 GMC Sierra 2500 hd. The contact stated that while traveling 20 mph, he attempted to stop and the brake pedal failed. The brake pedal could not be fully depressed. The contact was able to slow the vehicle to a stop and merge to the side of the road. The vehicle was towed to a private mechanic where it was determined that the brake lines were completely rusted. The vehicle was repaired. The manufacturer was not contacted about the failure. The failure mileage was 108,500 and the current mileage was 108,505. The VIN was not available.
Was driving down road at speed limit, hit brakes, rear brake line burst (was severely rusted). I was unable to stop vehicle and proceeded through a red light at a busy intersection with my 2 year old on board in his car seat. How we both made it out of that incident unscathed is amazing. I was unable to stop and had to pull off to the shoulder and hit the parking brake. It took my son a good 2 months before he was able to rid himself of fear and anxiety due to what happened.
I was approaching a one lane covered bridge on the way home from work and another approaching vehicle failed to yield. I made an emergency stop by pressing firmly on the brakes. Brake pedal went right to the floor. I had to quickly use my foot operated emergency/parking brake to stop from having a head on collision. I had to pay close to $1200 to have the entire brake line system replaced due to severe rust of the brake lines. I am very fortunate that this turned out the way it did. My life and the lives of others are being endangered by gm not using a material that is resistant to corrosion.
The contact owns a 2003 GMC Sierra 2500 hd utility truck. The contact stated that while traveling 30 mph, the brakes became inoperable. The contact was able to merge off road where the vehicle was towed to the dealer. The dealer confirmed that the brake lines and brake pressure control module failed. The vehicle was not repaired. The manufacturer was not contacted. The failure and current mileages were not available. The VIN was not available.
Brake lines all rotted away near abs module mounted in frame. I had to take to a shop to get all line replace from abs module forward. This truck has never been near salt ever. 100,000 miles and already relining the truck! fuel lines look like they only have a few months left. This is a danger and a huge waste of money for a buyer I have had other gm cars that are 30 years old with 350,000 miles with factory brake and fuel lines.
I was driving my 2002 GMC Sierra 2500 hd on i95 when traffic came to a sudden stop. I slammed on the brakes at which point the abs system started pulsing the brakes, but the brake pedal suddenly went to the floor with no further brake response. Thankfully, the brakes slowed the truck enough prior to failure to prevent a collision at 65 mph. I hit the car in front of me at ~5-10 mph, causing bumper damage to my truck and the car in front of me. I was able to get the car to the side of the road and to my horror I had no brakes. The vehicle was towed to a local authorized GMC dealer who has maintained the truck for me. They confirmed that the brake lines catastrophically failed when I slammed on the brakes. The rusted brake lines burst when I slammed on the brakes. They indicated that all of the brake lines had to be replaced do to rust throughout. I can't believe I have been driving this truck around with a pending catastrophic brake failure without warning from gm or the servicing dealer. If the word is not put out to owners of affected GMC truck, lives will be lost. I shudder to think what could have happened if I had been pulling up to a pedestrian filled crosswalk when the failure occurred. Updated 10/03/lj.
Depressed brake pedal to stop truck and pedal went straight to the floor. Front brake lines had ruptured due to corrosion. This truck is my main tow vehicle and I had a small trailer on when this occurred. My truck has not seen much winter use since new and I am the owner since new.
While driving down a country road in my pickup truck my brake lines failed in 2 spots due to rust and corrosion. I was pulling a trailer also. Very very dangerous. Lucky to have acted so fast in using the emergency brake.
Steel brake line ruptured under truck causing loss of brakes while towing a boat.

Was traveling on a straight stretch of road approaching a red light. As I attempted to apply the brakes the brake pedal went straight to the floor - the vehicle would not stop. I then dropped the transmission from "d" or drive to "l1", engaged the "tow setting" of the transmission, and applied the parking brakes while maintaining the parking disengagement lever in the "up" position in order to stop the truck. The brakes failed. Gm dealership confirmed that the brake lines had rusted through. The entire brake system froze in place resulting in the replacement of the lines, rotors, discs.
All the brake lines are rusting through.

Tl- the contact owns a 2005 GMC sierra 3500. The contact stated that while driving 40 mph, the brakes were engaged and the vehicle failed to stop. The contact mentioned that he had to engage the emergency brake in order for the vehicle to stop. Also, the contact stated that after inspecting the vehicle he noticed oil leaking. The vehicle was not taken to the dealer. The vehicle was taken to an independent mechanic who diagnosed that the brake lines needed to be replaced. The manufacturer was made aware of the failure who did not offer any assistance. The failure and current mileage was 42,000. The VIN was not available. Pmb.
Started the truck and applied the brakes to shift into gear and the brake pedal went to the floor. After several times pressing the pedal there was no brakes at all. The truck was towed to the dealer where I was informed all the brake line were rusted and needed to be replaced at a cost of $1,300. 00. The truck only had 35,000 miles on it. If I had been driving, I am sure this would have likely caused a serious accident.
First the transmission cooling lines rusted out costing over 400. 00 to repair. Today the brake lines failed because of rust. This will be a very expensive repair. I was fortunate that I was able to avoid crashing the truck when the brakes failed.
The 2005 GMC 2500hd fwd (well maintained and oiled to prevent corrosion) experienced a failure while towing my 24' pursuit fishing boat (7200 lbs. ) home from sturgeon point marina to hamburg, NY 14075 (approximately 10 miles) with "minimal" stopping capability as the dot 3 brake fluid was being expelled. I had to feature the throttle to negotiate stopping senarios without issue. As of 8/20/12, this vehicle is with fuccillo Chevrolet, inc. (grand island, NY) for overhaul of entire braking system; including fuel lines. The certified technician suggested the entire brake lines system be replaced along with the fuel lines due to extreme corrosion. All this work is being performed since the excellent condition of the vehicle. The estimate for this work is approximately $2250 to replace all lines (brake / gas) affected by severe corrosion. This condition is a result of poor material selection not capable of withstanding normal winter conditions found in the northeast. The same standards should be used as selecting exhaust system material. Brakes can kill you. . . . Exhaust systems can not! final note: truck driven 50 miles per week to work (10 miles each day). During winter months, the residual salt is rinsed as required on a weekly basis (or sooner) to prevent corrosion. This truck prior to winter driving has had oil applied to the underframe, apparently, the brake / fuel line where not adequately treated.
Leaving small rural road. Brake pedal went to floor and vehicle rolled through stop sign. No oncoming traffic. Upon inspection, left forward brake line had ruptured due to corrosion. Only matter of time before other brake lines will fail.
