Failure Date: 08/24/2018

Have replaced calipers 3 times since August 2018. Started with squealing of brakes and then taking to mechanic to find that caliper was "frozen" and eating up the brake pads. The abs pump is not releasing appropriately and causing the brakes to remain in a braking mode while driving. It is not both sides at the same time. It has alternated sides so the master cylinder was ruled out as an issue. Inner and outer tie rods ends were replaced first, and then the first set of calipers. Then brake hoses, pads and rotors were also replaced. At that point, the squealing happened after about two weeks of driving and we found it was a caliper sticking. Thinking that it was a faulty replacement, it was replaced and did fine. Two weeks later the same happened with the other side. This has happened another time since the first set was replaced. At this point my mechanic had figured out that the abs pump was what was causing the issue and because it was somewhat intermittent, it didn't trigger a code in the vehicle. He was able to do testing that showed failure on the side the caliper was not releasing on and then after about 5 minutes, it released, he retested and it passed. He called his oem supplier who then told him this was a "known issue" and that there were only 5 of the pumps available nationwide and all were spoken for. About a week later, the rep let him know that the part was in production with a ship date of Dec. 3rd 2018.

Tl the contact owns a 2015 Chevrolet Suburban. While driving approximately 10 mph in heavy traffic, the vehicle lost all braking ability and the brake pedal traveled to the floorboard. Also, the brake warning indicator illuminated. The contact also stated that the failure occurred two other times. The vehicle was taken to Chevrolet 112 (2096 NY-112, medford, NY 11763) where it was diagnosed that the master cylinder failed and needed replacement. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 58,000.

Failure Date: 06/29/2017

While driving on i90 in stop and go traffic, the car in front of me stopped. I applied my brakes and the pedal was hard and would not depress. As a result my car would not stop and I hit the car in front of me in the rear end. My air bags went off. I received an air bag burn. The car in front of me struck the car in front of him. Both other drivers claim they were injured. My car cost $15,300 to repair. Chevrolet is aware of this problem, issuing preliminary service bulletin pit5361 in 2015, addendum b in 2016 and addendum b in 2017. The problem is a faulty vacuum pump, master cylinder, brake booster, vacuum line, and vacuum pump belt. I was never informed of this problem. I have been driving 50 years and this is my first chargeable accident.

The rear brake line failed for the second time and caused me to have accident. The issue is that the front brakes did not stop the vehicle and the brake pedal went to the floor. When this happened the first time 2009 the dealer changed the master cylinder and other brake components stating that is why the front brakes didn't work however this failure was exactly the same as the first incident absolutely no brakes.

Failure Date: 03/24/2016

I have a very hard time stopping the vehicle suddenly. Pedal will go all the way to the floor. Abs never activates because wheels will not even attempt to lock up. (except in snow or ice) when sitting still pedal will push entirely to the floor. Have replaced all brakes and rotors and front calipers and master cylinder. Seems to have all the symtoms of campaign number 04v045000, but when I enter my VIN number, that recall does not come up. I rearended someone about a year ago ( no damage) since then I make sure to leave about 150 feet between me and the car in front of me.

Failure Date: 07/31/2015

Driving down l street in omaha, nebraska approaching 96th street. Brake pedal goes all the way to the floor and vehicle would not stop. I was able to pull to the side of the road just before light at 96th st on a slight hill which assisted vehicle stopping. The brake master cylinder was low. The car was towed to yeck's auto in bellevue, ne. Had I been following other vehicles closely or approached a quick changing yellow light the vehicle would not have stopped. Yeck's auto has since determined the brake lines failed. After internet investigation yields that gm has known about this defect. No warning lights, no indication of a problem. This vehicle needs to be recalled. The vehicle has been serviced at beardmore Chevrolet in bellevue, ne at prescribed intervals since day 1. Gm saying this is normal is frankly unacceptable. How many people have not been as lucky as I was on this day.

Failure Date: 09/01/2014

One of the metal brake lines between the master cylinder and the abs modulator valve ruptured during a stop due to corrosion. All brake lines in the vehicle have similar levels of corrosion near the area the aforementioned line ruptured, and at various other locations on the vehicle. The transmission cooler lines had failed approximately 18 months previously due to corrosion. The corrosion and rust on many components beneath the vehicle and in the engine compartment is becoming rather concerning.

Failure Date: 05/19/2014

First incident eastern 05/19/2014 aprox 119000 miles: after hitting the brakes hard to avoid a vehicle that pulled in front of me, the brakes failed (brake pedal would go to the floor with little braking action). Managed to safely stop. Found burst brake line in the rear end of vehicle. Two rear corroded rear brake lines replaced by local repair shop. Second incident milford 09/17/2015 127336 miles: hit brakes going down driveway. Brakes were soft and sank to floor. Brake line going to front passenger wheel was burst. All the brake fluid drained quickly out of the master cylinder onto the driveway. Ordered acdelco 22932592 gm original equipment hydraulic brake pipe kit and am in the process of replacing all brake lines as all of them other than the two replaced in PA are very corroded. The replacement lines are not really oem as they have a nylon coating for better corrosion protection.

The master cylinder and brake line caused a complete brake failure. All the brake lines are severely rusted, compromised, and all must be replaced. Fortunately the failure happened in a restaurant drive through. Moments before pulling into the drive through, I was driving my daughter on a busy roadway with a 50 mph speed limit. I do not feel brake lines should be made of materials that can corrode and fail without any warning whatsoever. The truck is very well maintained. With non-corrosive metals available for brake tubing it is inexcusable from a safety perspective. The government needs to address this to prevent clearly foreseeable injuries and deaths.

Failure Date: 02/24/2014

The contact owns a 1999 Chevrolet Suburban. The contact stated while driving approximately 25 mph uphill, the vehicle unexpectedly accelerated. The brake pedal was applied with force repeatedly without any response from the vehicle. The vehicle eventually came to a stop and was towed to an authorized dealer for diagnosis. The technician stated that the master cylinder was fractured and caused the brake lines to burst. In addition, the radiator would need to be replaced. The vehicle was not serviced because the required equipment was not available to perform the repair. The manufacturer was notified of the defect. The approximate failure mileage was 105,000.

Failure Date: 02/20/2014

2001 Suburban - when I applied my brakes coming to a stop sign the brake pedal went almost to the floor leaving me barely any braking power, but fortunately since I was driving at a slow speed (25 mph) I was able to stop in time. I then drove to a garage which was very close to where I was and had them put it up on the rack to look at it. They informed me that all of my brakes lines were very rusty and the one rear line had broken, I left it there and had that line replaced but after replacing that line another 2 lines broke during their testing after the first repairs. I ended up having 3 rear lines and the 2 lines to and from the master cylinder replaced (3 that broke and 2 other ones that looked really bad) at a cost of about $800, I am now going to get the remaining 2 front brake lines replaced "before" they brake on me also. These 2 lines are the hardest to replace and I was given an estimate of about $700-$800 to replace them. The one mechanic told me that a couple of years earlier his brake lines also broke on his Suburban coming up to a red light and he had to drive on the birm to avoid rear ending the car in front of him. He had to replace all of his Suburbans brake lines. I live in western PA and have been driving here for almost 40 years with many different vehicles during that time but I have never had brake lines rust and break like this. From what I have been reading, this must be from faulty brake line material, none of my many other vehicles have ever had this happen so chevy cannot just blame it on living in a snow/road salt area. *** I plan on going with a different manufacturer when I get my next SUV.

Brake pedal went to the floor and car would not stop. Had to use the parking break and run into the curb to stop. Found there was no fluid so filled the master cylinder and pumped brakes. Fluid was running out of the line just under the driver's door. I inspected all the brake lines and found them severely corroded and will now replace them all. The last time I had to change a steel brake line was on a 1952 Buick, but that was in 1984, when the car was 32 years old. There should be either a recall or at least a notice from Chevrolet that this could happen. I could have easily wrecked my truck and/or killed a pedestrian.

Coming to a stop light the brake pedal went to the floor. Only way I could stop was by using the electric brakes on my trailer to stop the combined vehicle. Examination revealed a rusted brake line coming from the brake master cylinder to the abs module at the abs module under the vehicle. Further examination revealed that the 4 brake lines from the abs module to the wheels were all rusted/pitted and about ready to rust through.

Brake failure. Metal brake line between master cylinder and caliper developed a leak due to corrosion of the metal brake line. Mechanic said all metal brake lines were rusted and corroded and needed to be replaced. I understand there is an investigation underway on these faulty lines. The replacement of these lines was very expensive and was definitely a premature failure in my opinion. Luckily my 20 year old son noticed the brake pedal was going to the floor while on the interstate and was able to safely exit the highway. If the line would have failed a few minutes earlier, he would have been in a crash.

Was driving vehicle on a 2 lane public road at approximately 35 mph when pedal suddenly became soft and required many actuation to stop. Vehicle was unable to stop in the anticipated distance and a collision with cross-traffic nearly occurred. On investigation, the master cylinder reservoir was empty and there was leaking from multiple brake lines from corrosion.

Brake pedal almost to floor, extremely long time to stop. No warning just driving in columbus traffic and lost brakes. Found master cylinder almost empty. Brake lines rusted through left side drivers floor/frame rail area. Dealer estimate $1200 to$1600. Seems to be a common problem as on line investigation verifies. Web site shows open case,no re-call to repair.

I was backing up my 2000 chevy Suburban 1500 in my drive way and the brakes failed completely while backing up the vehicle. The brake pedal went all the way to the floor. I pumped the brakes several and the pedal went to the floor each time. There was no warning that the brakes were going to fail. I was able to use the emergency brake to stop the vehicle. The rear brake line is severely corroded and the line failed at the chassis location above the rear axle above the coil spring bracket. There was a large about of brake fluid on the inside of the tire, chassis and on the ground. This failure also indicates the master cylinder failed because there were no front brakes either. Upon inspection, all the brake lines on the vehicle are severely corroded and will need to be replaced. I am disappointed in gm engineers to produce a vehicle that could have a failure of this nature. Their design controls and process using a dfmea (design failure mode and effects analysis) would have had corrosion on brake lines as a potential failure mode. If their marketing knows that a large percentage of vehicles would be sold into regions that use corrosive agents to keep our roads and highways clean in the winter, then they should have shown that the break lines could fail given their choice in brake line materials and coatings used on this vehicle. Also, I am disappointed in my gm dealer and the state safety inspection process where I live that should also have caught the fact that the brake lines were severely corroded, especially since I had to have had my rear backing plates replaced on the same vehicle last year due to a corrosion failure that rendered the emergency brakes useless and would not pass the state inspection process.

Travelling downhill toward a t-intersection, applied brakes and pedal went to the floor. Missed an approaching vehicle from the left by inches as I swung to the right, thru a stop sign. Returned home, thinking a rubber brake line had failed. Upon inspection, the steel brake pipe approximately ten inches in front of the right front caliper had split open due to corrosion. When I inspected the tubing prior to purchasing replacement parts, I discovered virtually all the steel brake lines were corroded to the point of failure, and in fact, I created another break in the same line as I attempted to loosen it from the plastic hold-down clamps under the left frame rail. Accessing the brake lines as they are routed between body and frame proved almost impossible, and am currently awaiting a recovery vehicle to take the truck to my inspection mechanic for replacement of all brake fluid lines/hoses from the master cylinder to the ebcm to each wheel caliper. The factory service manual mandates a minimum of 3/4" between any parallel brake lines, presumably to prevent bridging with mud/debris which might abet corrosion. In many cases, my steel brake lines were within 1/4" of one another. Some steel lines lay against steel frame rails with no clearance. This, however, would not account for the level of corrosion I discovered throughout the entire underbody of the truck. The only non-corroded portion of my brake system is the two lines immediately from the master cylinder downward to where they travel rearward along the left frame rail. Everything else is at the point of failure.

One of the brake lines from the master cylinder to the abs control unit ruptured due to severe corrosion, resulting in severe loss of brake fluid, and near complete loss of braking force. Replaced both lines on the advice of my mechanic who stated that the other line was just as badly corroded. Subsequently, the brake line from the abs control unit to the rear brakes failed due to severe corrosion in December of 2012, resulting in complete loss of rear brake effectiveness. Replaced that portion of brake system, and very concerned about the remainder of the original equipment brake lines still extant.

While driving at 45 mph on a medium traffic city road, the brakes were applied while stopping for a traffic light that had turned red. The brake pedal did not respond quickly enough and had depressed all the way to the floor. The vehicle was able to slow down enough to be driven into an empty parking lot. As I got the vehicle to stop, I opened the engine compartment and saw the brake fluid level was very low. The vehicle had its preventative maintenance done on it just three weeks prior and all fluids were checked topped off (all of which is documented by an oil and lube garage). I was able to get the vehicle back to my home and had inspected the issue. An area along the frame rail were the brake lines go from the master cylinder to the abs motor was leaking. The brake lines were severely corroded in just one area, inspection of the rest of the brake lines were ok. Its just odd that it was corroded in just the one area and nowhere else. There was no warning that the brakes were about to fail or any indication that the fluid level was low.

I started up my 1999 chevy Suburban in my driveway this afternoon and the brake pedal went to the floor. I opened the hood and noticed brake fluid splattered all over the area below the master cylinder and all over the ground. I discovered that the line to the left front wheel rusted to the point of failure. I checked the other brake lines and they are badly corroded. This truck has never left me stranded in 13 years. I do not want to see it go, but this may be the end. Also, a little over 1 year ago, I sold my 2005 tahoe to a man who told me he had a 1999 tahoe. He was buying my tahoe because the brakes lines on his had corroded and ruptured. He was careful to climb all around and under my tahoe to check for brake line corrosion before buying. I just researched this problem, and it appears to be common. Many of these trucks are still on the road. How many will have to be killed before anything is done about it?.

The contact owns a 2001 Chevrolet Suburban. The contact stated that when applying the brakes, the brake pedal was depressed into the floorboard. The vehicle did not respond and the contact drove into the curb to prevent a crash. The vehicle was towed to a local mechanic who performed a diagnostic and located the failure as a ruptured brake line, caused by corrosion. The mechanic replaced the brake line and the master cylinder. The failure and current mileage was 113,854.
