    concerned_dad,

    I apologize for the problems you are experiencing with your vehicle. Are you having the issue fixed by a GM dealership or an independent shop? Please keep me posted.

    Thank you,
    Caron, GM Customer Service

    that is exactly how I 'fixed' my brake problems with my 2001 Silverado
  • I have an 03 GMC 1500 Z71 with just over 200,000 miles. Bought it used at 140k - do not have contact with previous owner anymore. It was a great truck for the previous owner who switched to a DuraMax for all his hiway time and better mileage.

    The ABS engages at about 5-7 mph just before it comes to a stop. It still stops ok since ABS only affects the front and fresh brake disc pads all fours, plus new front rotors and emergency shoes at 193k. But this is really bugging me. If I hit the brakes HARD it doesn't do it, just when stopping normally or even very gently.

    I just had the ignition switch replaced which was causing power loss to the fuse box on specific circuits that caused the blower motor to quit, ABS light, brake light, and service 4wd message, and no 4wd. That was that way for a few months since nobody local wanted to mess with it and the dealer is 45 minutes.

    All that is fixed, but now that the abs is working it is engaging incorrectly. I have driven over 150 miles and still doing it. I had a wheel bearing clicking after long highway runs at 165K so I replaced both hub assemblies without changing wheel speed sensors. Then got a abs light last year and I changed a wheel speed sensor to fix that. I am getting no codes or lights.

    From all the posts, it sounds like I should clean my wheel speed indicators and the mounting on the hub, then check hubs for wear/slop, then check vehicle speed sensor in transmission. Anything I should add?
  • My 03 GMC Z1 is over 200k in NC with light to medium road salt exposure. It has none of the rusting issues mentioned. I will check plant and manufacture date and get back to you all. There must be a common denominator. We have had a half dozen HDs, 1500s or Z1's between family and friends many with 100k+, mine with 200k+. None with these problems.

    As for service, it all depends on the dealer and their mechanics. Some are amazing and some are as dumb and helpful as a box of rocks. Just sayin'.

    You may want to consider NOT using your GM dealer as their brake lines are obviously faulty and they don't seem to be offering an alternative. The nickel alloy product was also used on my tuck and so far so good. The rest of my lines were replaced with SS, also not available from GM. I have noticed the newer GMs have a coating on the brake lines, but those that are few years older will just continue to fail unexpectedly. Oh well, it's just the brakes on a 5,000 lb truck, no big deal right?
  • A little while ago my ABS brakes started working even when it didn't need to. I pulled the fuse and now the lights are on all the time. Is the brake module seperate from the pump? or do I have to change the whole thing. Cool it be just a wheel sensor? Seeems like everything that goes wrong with my 2002 Gmc is a common condition!
  • at 98,000 miles, I pulled my fuse over a yr ago, after senors checked, hubs changed, master cylinder replaced, The ABS light stays on, no problem with brakes since. I was at the point to never drive the truck again and take it to the auction as I would not be able to sell it to someone knowing it had this problem. Seems from this forum and my friend who is a chevy dealer mechanic, this is better than spending $1000's as there is no actual certain fix, sensors, hubs, brake lines. who knows. Had the Chevy recall to clean sensors , forget when that was, 2-3 yrs ago, , that didn't help. Dealer said bring it in again and expect at least a $1200 fix or more.

    2002 Chevy 4x4 pick up,
  • Hateful Jim here- My truck, the 2001 silverado that hit the pole at lowes, once upon a time, the truck would just up and decide it wouldnt crank. Wouldnt do Nuthin', Not all the time, mind you, just sometimes. Chevy said they couldnt find anything wrong with it, NO CODES, NOTHING!! After 3 times in the shop at GM, we told the Chevy Mechanic "TAKE IT HOME AND DRIVE IT FOR A WHILE"--
    ABOUT 2 weeks later, the mechanic got up, and went to get in to work, and guess what?? That was finally fixed, but some things never change.
    GM DOESNT HAVE A CLUE!! I like what you said about there being "NO ACTUAL CERTAIN FIX", cause thats EXACTLY correct. They cant fix it, cause they dont know what the problem is, just like my "Service 4wd" light. After changing BOTH MOTORS, AND THE SELECTOR SWITCH, I Finally got that fixed, but Chevy couldnt find anything wrong with THAT EITHER. GO FIGURE!!

    and GM Customer Service and GM Engineering ( ???) sit idly by watching previously loyal owners spend cash and frustration on poorly designed parts that repeatedly fail ( eg steering col shafts and sensors), trucks the mysteriously won't start, trucks that suddenly don't stop and dashboards that electrically go haywire at 81,000 miles. But heh, they offered to fix that dash as long as you don't go over 70,000 miles. Most successful engineers learn from their designs and improve their performance and reliability. I am now resigned to the fact that GM just clads the same truck with some redesigned sheetmetal and then hires a new marketing firm.

    GMCustSERV --here is one last clue--Upset customers that call to complain are much better than customers that never call again. Pick up the PHONE!
  • Hateful Jim here, I graduated in 1979 and bought a new 79' Silverado, then i bought a used 83' silverado , an 87 Silverado "pre-owned", a 93 Silverado "pre-owned", then bought a NEW 2000 extended cab Silverado, but had to part with it, and NOW i have the 2001 Silverado.
    Over the span of 32 years, i have had 5 Silverados, (but the 2000, and the 2001 are the only ones that have given me any problems). I've been a DIE-HARD Chevy man all my life!!, but- AND THATS A REALLY BIG BUT-- With the "Stimulus" we gave GM, on top of the cost of their new trucks, then add on the " I DONT CARE" ATTITUDE you get from GM, and the in-ability to ADMIT that there's a problem ( or un-willingness to admit that theres a problem), not to mention that when you take your truck in there, they try to make you look and feel STUPID- Add all that together, and what i come up with is- I'M DONE WITH GM. I wont even buy a USED chevy from now on. Ford didnt take ANY stimulus, my next truck may just have to be a USED FORD.
  • You sound sooooo informed! Did you ever find a picture or diagram for me to recognize these parts or have any other helpful information for me. I can do the front brakes no problem, but my 2005 Chevy Silverado Duramax Diesel Dually needs the rear pads and rotors replaced-I am a visual, but I will follow your instructions posted here WITH diagram if possible.
    Thanks so much!!!

    The costs to repair all the problems are astronomical; unless you are a do it yourself type. Since it is a 2500HD it may be worth fixing up depending on the body/interior etc. My GMC is a 2000 1500 Z71. We have no salt etc.down here and the backing plates are in excellent condition. (new aftermarket
    ones are available in a two piece design so you don't have to pull the axle to replace them, at least for 1500's) Why GM doesn't use better grade material is, well that's just GMC. Mine only has 50k miles and is garaged etc. All that aside it drives great and really is more of a car than a truck.
    The problems I've encountered are: ABS failure nearly resulting in rear ending another vehicle; Parking brake design (premature wearout) is a joke and typical of GM engineering(they are not smart enough to correct it so they went back to drum brakes (rear) in'05. Spongy brake system even after repeated flushing; intake manifold gasket failure. (new aftermarket fixed that). The roof on the extended cab is flexy (newer ones have stress ridges in it). If you fix up the '99 You may want to remove the fender flares and see if there is rust under there.
    So even after correcting all the problems on your '99 it could drop the crank sensor (99's did that) and if I had waited until Toyota came out with a full size p/u I'd never have a GMC. And I'll never buy another. A GMC/Chevy mechanic (small town) tells me that the Trucks are nothing compared to the new smaller SUV's. They get at least 10 a day in for problems.

    Oh yes my Sierra has Mexican springs and Chinese tail gate cables. Lord knows what's lurking up under the dash. Good luck to you. Hope you get two new Toyota's!!!!!! jaxtix
  • What can I do about the terrible brakes on my truck?

    The pedel squishes to the floor. I've replaced the master cylinder, rotors, & pads & ABS module... and they are only slightly better. It's been properly bled several times. There are no leaks. The wheels are OEM. The tires aren't over-sized. It's like the master cylinder isn't pushing enough fluid to the calipers. Is there a master cyilinder that pushes a larger volume of fluid?

    Any ideas for me?

    I am having the same problem on an 02 2500HD. I have the parking brake peddle unit off and don't see where that spring goes.

    Did you ever get yours figured out?
  • Hi Laura, I have had the same problem with my 09 GMC Sierra. I'm in the process of having the rear brakes replaced again. This is either # 9 or 10th time they have machined my rear drums or replaced them, along with the shoes. They also replaced the front rotors and pads. I'm out of warranty now but was told by customer service GM Canada that they would help me if I have further problems. Could you contact me so I can get this nightmare over with and fixed properly!
    Thanks Pat

    calpat,

    I apologize for the problems you are experiencing with your vehicle. Unfortunately, I am unable to assist customers outside of the United States. I would encourage you to contact GM of Canada directly at 1-800-263-3777. Hours: M-F 7:30am - 11:30pm, Sat 7:30am - 6:00 EST.

    Thank you,
    Caron, GM Customer Service
  • Thank you Caron, I have talk to GM Canada, this will be the third case I have opened with them. They claim to have no knowledge of any other truck having the issues I have had with the brakes. There is a bigger problem than just changing the drums and shoe's every 3-4 months. That is just a band-aide! I see that you have had customers with the same problem and I would like to know what the fix is? I believe it has to do with the proportioning valve or the traction control/ anti lock system. The rear brakes are getting to hot and warping the drums. Could you talk with my GM rep? Her name is Giselle, Ext. 2320 and her hours of work are 3:30pm to 11pm.
    PS. I've also had replaced
    - Throttle Control Valve and Gas pedal
    - Power steering rack
    - Front & Back bumpers replaced do to rust
    - Front rotors and pads
    - Rear drums turned(machined) x 3
    - rear shoes replaced x 8
    - rear drums replaced x 6
    - all tires rebalanced shortly after purchase
    - All windows re-adjusted due to looseness.
    - Rear main seal on the back of the engine leaking, transmission has to be removed for this repair. (Scheduled to be repaired Sept. 28/2011)
    - I'm now 6000 miles over warranty.
    There is more but it was minor.

    This is my first GM ! Nobody wants to fix the real problem.
  • Hello all. I hope no one jumps down my throat for not having read the multitude of posts here as I ask my question....but.....here goes.

    My 19 year old nephew has a 1997 GMC Sierra 2WD Extended cab pickup. It's got over 100,000 miles on it and for the most part he has had nothing go wrong with it until now. Over the past couple of weeks he has begun to experience the ABS and BRAKE lights coming on...when they do...the truck lurches as if it's wanting to die....but doesn't. However occasionally when he pulls to a stop at a stoplight it will die. We took it to a mechanic who put it on a diagnostic and found nothing. They checked the master cylinder and brake lines and found nothing either. I think it might be the fuel filter or fuel pump causing the very intermittent stalling. I had him fill the tank with gas and put a bottle of fuel injector cleaner in it...he says it runs better and hasn't stalled, but the ABS/BRAKE lights still come on occasionally and the truck lurches.

    Anyone have any ideas?

    I just don't want my nephew getting stranded and not knowing what to do.

    Thanks for your help.

    You could start by cleaning the ABS sensors.
  • I had the same eaxct problem went through about 3 grand in replacement brakes and parts. I unhooked the abs under the truck. Then i unhooked the fuse under the hood. Then when that didnt work i replaced the master cylinder. seems to be fine now.
  • Thanks for the information. Just took it to the shop and they said it was the ABS speed control module going out. The fluid leaking was from corroded supply and return high pressure cooling connections.....all totaled $700....let's hope this solves the problem.

    Again...thanks so much for your advice, etc.
  • While you are at it, check your brake lines, especially on the frame mount near the front drivers wheel. These are known to fail there and the problem is being investigated by NHTSA. Repair the lines and minimize the risk of a bad accident as they are known to fail during a hard stop. I am speaking from experience on my 2003, and others have reported the same failure mode. Both front and rear lines fail there. You can save your receipt and at least take pictures of the lines if they are corroded there. The NHTSA will take the info, and maybe someday we will be compensated for this unfortunate design defect. Apparently newer GMs now have the proper coating, as I assume they have used a poor composition of steel.
  • not sure why all four brake calipers are sticking,i have tried removing the calipers and pushing the pistons back in with a sea clamp,but they seem to be working,the calipers just won't release off the rotors.they get extremely hot and sizzle when water hit them,brakes have cracked from the heat.this has slowed the truck down a lot.
  • I was wondering if you have heard anything back from people ragarding a class action lawsuit? I am NOT a lawyer, but I am desperately trying to find info. on starting a class action suite against GM. My husband almost got into a very bad accident because brakes went out completely ( rusted out ) Then while they are fixing brakes, we are told most of the frame is rusted out. I have seen hundreds of these postings and would really like to find a way to get everyone on board for a lawsuit. ANY information you can give me would be great. thank you

    Patti,

    I am sorry to hear about your experience. Did you ever have a case with customer assistance regarding your concern. We would be happy to look into this for you with more information. Please feel free to contact Christina by email. Thank you.

    Tricia, GM Customer Service.
  • I've been following this blog for 2 yrs, I got no where with dealer(s). Who is Christina and what is her email ? or better yet, a phone number. Just from my experience, if you are with GM and do give a crap, why don't you tell GM or have Gm actually contact all the people they sent the recall to 4-5 yrs ago ?
  • Tricia,
    How would we go about contacting GM Customer service to be compensated for the early brake line failures? I had two rusted out lines in one particular area, but the entire lines severely corroded on a 2003, first within 4.5 years. My expenses to replace all lines was approximately $1300. Luckily, I was able to avoid 2 collisions, but it is was close. It would be helpful. to say the least, if GM did compensate us for this. How do we go about it? I have receipts, pictures and some of my old lines.
    Thanks,
    Ed
