Chevy Silverado and GMC Sierra Brake Problems

    Yes. I lost my brakes last month during a panic stop due to a ruptured steel brake line. :blush: 2 years ago, at 50,000 miles, my front brake line ruptured requiring me to run off the highway to miss a slowing tractor trailer. :confuse: The entire brake line line system had incredible, significant corrosion ( no protective coating). My oil cooler lines corroded and ruptured at 3.5 yrs old and 30,000 miles, causing a complete loss of oil pressure, luckily, I was in a parking lot. :cry: Last year my power steering pump corroded losing all fluid, causing loss of power steering and brake boost while towing my boat. :mad: Some of the power steering lines were on their second replacement. 2.5 yrs ago, my fuel line corroded and caused a fine gasoline mist under the truck, since that line was pressurized. Today, the fuel lines are extremely fragile and will require complete replacement right up to the fuel rail, as the steel fuel crossover at the top of the engine is also oddly very corroded. My truck only has about 65,000 miles today. I have never experienced a chain reaction of corrosion like this. My first GM was a 65 Pontiac and I still own a 67 and 68 after 30 yrs. Oddly, my rear bumper started rusting two weeks after I took delivery of this Sierra HD. Do you think that this is normal for GM trucks or could my truck possibly have some type of defect causing all these lines to fail so prematurely? ( transmission lines and air conditioning lines have also required total replacement). I have saved my brake lines if you would like to examine them, as the NHTSA is also asking me for samples.

    Jim,
    Hard to disagree. At this point, I think I am further ahead keeping what I have vs. risking another $40,000. Though I have new front bumper, I have chosen to leave the original one on, that GM recoated under warranty. The significant rust is such a stark contrast to the rest of the truck, that many people ask what has happened. I show them the corrosion under the hood and it stuns them. Typically, these people are interested in buying new trucks, so it makes them think twice. 2 people this week alone have asked and I have l told them the problems. This has caused at least one person to hesitate with GMC and I keep those I know updated. I Have been a staunch supporter of GM for 30 yrs, so now I'll just continue in hopes GM may listen. After pricing a new 2011 last year, almost ready to pull the trigger, I asked about what has been done to correct these issues. I received a shrug. Then the service department explained that they would not replace my rusted SS muffler ($1100 !!!) under the 8 yr emmisions warranty ( catalytic is welded to it). Said, well it's not all stainless. I had my window sticker , and showed him what it said ' Long Life Stainless'. He then shrugged. The last straw, "well we must reduce your trade in value as the front bumper is rusted!" I asked, but that IS a GM defect, that you did not properly fix under warranty. A third shrug. I left the 2011 sitting on the lot and the contract in the salesman hands. Frankly, with all the hassle and trips to the shop I have been patient with, I will continue to patiently wait for resolution. I had very good dealer, 3 purchase of new GM vehicles in 10 yrs. All future purchases are now on hold. I may pull in to a few more GM dealers though and show off my specimen to more customers. I've met some nice people that truly appreciate the information.

    Jim, the reason the GM representatives are asking for additional information is because info posted here is not verifiable. We do not ask for any proof that you are who you say you are or own what you say you own when you register to post here.

    The GM reps ask you to contact them off-list with that verifiable information so they can properly document your complaints. Otherwise, it's just words on a screen... from an otherwise anonymous source.

  • Yeah, i know ya'll are just looking for information. I took my truck to smoky mountain chevrolet, and they said that the reason my abs light came on was that it was dirty, and needed to be washed out, after a trip to Florida. Yeah, right..... Turned out to be a bad wheel bearing, found out too late, AFTER the abs wouldnt let the brakes work, and i had to use a big yellow pole at LOWES in Franklin NC to get the truck to stop!! They also said that the Check 4wd light didnt show a code, but i had to bring the problem here, to find out that the truck had 2 motors. I changed both motors myself, AND the pushbuttons before i got the check 4wd lite to go out, (THAT THE MECHANICS AT THE LOCAL CHEVY PLACE SAID THEY COULDNT FIND ANYTHING WRONG, EVEN THOUGH I COULDNT GET THIS PIECE OF CRAP TO GO INTO 4WD). I still owe 3100.00 on this 2001 Chevy. It kinda straps my butt that ya'll took a stimulus, but you cant even hire mechanics that can find out whats wrong with the trucks ya'll design and build.
    I'm 49, and since i graduated in 1979, i have bought 5 new chevrolet trucks, over the last 29 years of marriage. Ya'll are just looking for information. Ford Motor REFUSED the stimulus, and they just re-called over a million trucks. I have NEVER OWNED a ford truck, but I SEE A FORD IN MY FUTURE!! KINDA WISH i had totalled this thing when i hit that pole. The clutch is now starting to slip, and the rear end pops too. (AND I STILL OWE 3100.00 ON IT, BY THE TIME I GET IT PAID FOR, IT WONT BE WORTH FIXING!!) YA'LL might want to tell your buddy O'bama, you need another stimulus check to help figure out what your doing wrong up there in motor city!! From some of the posts on this site, it kinda sounds to me like I"M not the only one that regrets buying a Chevrolet. Personally, i dong give a crap if you believe me or not about my truck, I guess the dealership here doesnt keep a record of the service requests, that would probably cost too much for ya'll to keep up with the problems you build into your trucks, huh??
    You have a great day, and if this thing will crank in the morning, maybe i will too!! (pardon me if i dont hold my breath!)

    2010 Silverado 1500. With 9500 miles on it total.Just had a service at the dealership and was informed that the remaing thickness of the brake linings were fronts at 10mm and rears at 5mm.Just what are the original thicknesses of these linings.This sounds pretty premature to be down to this stage.And believe me I dont ride the brakes or deliver parcels.Tnx.
  • My 2001 is also suffering from rusted brake lines. My son was driving the truck this past summer when one of the steel lines ruptured above the fuel tank. My local garage repaired the problem. Today my brakes light came on. Upon inspection, the steel brake lines are badly corroded and fluid is leaking just below the firewall on the drivers side.

    1. Does anyone know when I can get stainless preformed lines for a 2001 Sierra extended cab?

    2. Has GM had a recall on this as this appears to be a serious safety concern.

    3. The brakes have been spongy since I bought this truck used in 2006. The GMC dealership said this is normal???

    I am a loyal GM customer and would like to continue to be one.

    If it had spongy brakes back in '06 I'm wondering why would you buy the truck?

    My '00 never had any issues that were brake related though I did replace the lines on my Silverado and my '02 Denali with the stainless steel version as it does wonders for a spongy feel with stainless you eliminate any flex in the line. When I refer to stainless I'm referring to braided stainless.

    Try www.summitracing.com enter your truck make/year and search for stainless steel brake lines. You will have quite a few kits to choose from. Good luck.

    FYI EVERYONE!!I just got a card from the U.S. Department of Transportation National Highway Traffic Safety Administration about the rusty brake line issue. They are "investigating an alleged defect in certain GM Model years 99-03 C/K Pickups and SUV's for brake line corrosion." I have to comment and answer a few questions and send it back. If I have any Questions I can also call a Robert Esser the Federal Safety Defects Engineer at 1-800-262-8309 x265 His email is bob.esser@dot.gov :)

    Hateful Jim here- At this point, i'm just trying to pay this piece of plastic crap off, although i bought it USED, and still had to pay about 12000.00 for it. I still owe about 2500.00 on it, and it only has about 134000 miles on it. Was driving down the highway sunday, and right out of the blue, the transmission goes out. Fluid level was fine, smells ok, a little darker than i like it to be, but otherwise seemed to be ok, except that with a small trailor on the back it did seem to have a little trouble in the towing mode.
    My guess is that GM has decided over the years, that they can make more money on replacement parts, and repair service, than they can make on sales. Obviously, they dont NEED your business, in the sales department. They just need another STIMULUS from the government, since they are losing your business, (never mind the fact that their workers are OVER-PAID, AND UNDERWORKED). Its alright, the big city UNION will take care of them.
    I called a local transmission shop, 1300.00 to rebuild the transmission, and NO- IT WASNT THE CHEVROLET PLACE. ANYONE THATS INTERESTED IN KNOWING HOW MUCH MORE THEY WOULD CHARGE, JUST LET ME KNOW AND I'LL GET A QUOTE FROM THE LOCAL GM DEALER, JUST SO WE ALL CAN HAVE A LAUGH AT THEIR EXPENSE.
    2500.00 + 1300.00 =3800.00, I think i can find a used TOYOTA 4x4 a little cheaper on a lot here in town, and it will probably last about twice as long as this flower pot.
    Ya'll have a great day- HATEFUL JIM said that.
  • I recently replaced my brake booster after I had an incident where my brakes went to the floor and did not brake. Shortly there after I replaced my front and rear brakes. The system was bled properly, however now my front brakes are locking up and smoking I am afraid to drive the truck due to the fact that it is now over heating and to avoid possible engine damage. What could be the problem and how could I fix it?

    Hi Lilricky, I am assuming that when you say replaced the brakes you replace the brake pads and rotors... not your calipers. My first reaction would be why are your brakes squeezing and not releasing.. I am thinking your calipers where original and the guide pins were never greased and the fact that you probably dont drive it too much.. that much means general moister re-rusts the pins to the calipers...making them not slide in and out with use... ( based on assumptions)

    I would replace all calipers and brake shoes... and possible the rotors... I have had the same experience with factory calipers on the rear .. not the front. I actually replaced all my brakes with after market ( SSBC) parts and now have 140K miles on a 1500GMC sierra...since i moved to after market ..i never have a brake issue.. ever ...you can search my other posts if you would like i have pics of the brake system I installed... the rotors and brake pads just replaced are probably ... EOL due to the heat and stress caused by the over heating...

    srry about the thought for sharing photos of the brakes I install, looks like Carspace.com >> was taken down .. send me an email if you want photos.. and i will send them to you .. :confuse:

    My 2007 Sierra 4X4 Crew Cab brakes smoothly but on occasion, particulary as I am nearly stopped, the pedal will go almost to the floor and I feel a very slight vibration (like the ABS system). A quick "pump" of the peddle and all is fine. I have 57,000 miles and thought it might be the front pads, so I replaced them (only about half used on the pads - but changed them anyway). Still happens. I'm a bit of a novice, but I did check the fluid, etc. No lights or alerts on the dash have ever illuminated. Possible to have a little air in the brake lines? Any help or suggestions would be appreciated. Thanks
  • I have the same problem with my silverado-1500 5.7 98' as el tuercas1 #273. could this just be brake lines? help please.

    bucktasker,

    I would encourage you to take your vehicle into the dealership to be looked at. Please keep me posted when the issue has been taken care of.

    Thank you,
    Caron, GM Customer Service

    hi camaro, not sure if you wanted all the solid steel lines for brakes replaced with a prefab kit .. i got and installed mine from classictubing.com, came in a big box and installed in a snap.. biggest issue the dealer had was that the SS fittings were much harder steel than the steel ends they were mounting to on the truck hardware.. took about a day .. for the dealer to pull the old and install the new ( see my other posts)

    2) no recall and they are not interested... otherwise they would have issues a TSB to deal with it...in lue of a recall

    3)MY BRAKES WERE SPONGY FROM DAY ONE! and the dealer said thats just the way they are for a 6300# truck... so i started the research and ended up here.....replaced all calipers with SSBC and russel braided lines from hard lines to calipers, now i drive a nascar...brake system .. no spongy there..my wife also drives it and says it great feel for a large vehicle

    we cart our two kids around in it and i used to commute into Boston... i needed good brakes.. i have them now.. I also just swapped the mechancal fan for two electric fans from flexlite....save some more HP and fuel milage, i used to have photos in carspace but they took that down.. i can send photos if you want ..
  • Almost a year later- and still don't have this truck fixed. Now the fuel line BROKE..rusted . The cab is rusting, the backing plates are totally gone, the parking brakes rusted. My husband wants to junk it, but my other car is a Ford Taurus- which we were just told will not pass inspection due to excessive frame rust. Why buy american? The US car makers do NOT stand behind their vehicles.

    In the woods behind our home someone parked a 1940s dodge years ago. Through the years hunters have used it for target practice- the only rust on that car is around the edges of the bullet holes. If I were able to drag it down and get it running it would be more road worthy than either of our vehicles.

    My daughters boyfriend just purchased a new truck, after seeing the issues we had with Ford and Chevy, he bought a brand new Toyota. His reasoning was at least Toyota will do a recall when something goes wrong. Are you listening GM?

    Unfortunately we do not have the option of buying a new vehicle. I have called GM customer service, they were usless. The answer was that the vehicle was out of warranty...well duh.

    I have a 2000 GMC Sierra 1500 with 138k miles. Last year I replace a broken right front
    Brake line. All the other lines are rusty and I am just waiting for the others to go. Last Saturday I pressed the brake pedal hard because of a yellow traffic light. I felt something give and know my pedal goes all the way to the floor. I ran the red light! I am lucky that no one was coming and that no one was already stopped! My master cylinder is almost full of fluid.
    I see a slight leak from the box under the driver’s seat. What is this box? At first I though it might be the master cylinder but, don't they give you a little notice? I have no Pressure and the small drip. Can the probleb :confuse: be the master cylinder or the box?

    I have a 99 Silverado 4x4 z71 new body style with 248,000 miles. Had the ABS module replaced at 86,000 mi (under warranty) and recently had all the brakes, rotors and one new caliper installed at 215,000 mi.

    The other day I was stopped at a stop sign and all of a sudden my foot went to the floor. I took it to P boys and they wanted to replace all my lines and the caliper (because they couldn't get the bleed valves loose. I checked the vacuum and I have hard pedal (with the vacuum line off) and when I put the line back on the pedal goes to the floor. Their is still about 1/4 inch on the pedal and if I stand on them they do stop the truck.

    The brake reservoir was real low and I added fluid, pumped the brakes, but see no fluid on the lines, ABS, calipers or wheels.

    Any ideas?
  • Hateful Jim here: Ya know, as much as i really do love my truck, (its a really nice looking truck, and when its working right, its a pretty decent truck), as i was saying, as much as i really do love my truck, EVERY TIME i read a new post, it occurs to me that GM REALLY DOESNT CARE ABOUT THEIR CUSTOMERS, they just wanna MAKE MORE MONEY, and produce more LOW QUALITY vehicles to sell for OUTRAGEOUS prices.

    JUST 1 question comes to mind here, Has anyone OTHER than myself thought that THIS just MIGHT be a good time for a CLASS ACTION LAWSUIT against general motors????? I mean, 376 posts by different customers, and drivers taking a chance getting KILLED by trucks that have defective BRAKE LINES, SOUNDS LIKE A SAFETY VIOLATION TO ME!! If these were COMMERCIAL vehicles, the DOT would be on this like flies on a dead horse!!! Now i'm not a lawyer, but i do believe that this problem with GM meets the requirements for a CLASS ACTION SUIT!! Anyone that knows how to start one, I'm willing to join up, before someone in MY family gets killed.

    brake lines rusted out and had them replaced, put new rotors and pads all the way around, calipers appear to be good. Now it seems when braking going downhill at very slow speed I hear an awful noise and the brake pedal feels like it is pushing back against my foot..it almost seems like the ABS is kicking in or attempting to kick in. This only happens when braking and coming to a full stop or almost full stop going downhill only. Never happens any other time. Suggestions?
