My truck is an '06 Silverado 1500 4x4 crew cab short box with a whole 10K miles on it.
Read where it could possibly be the wheel sensors, with corrosion formed between the mounting surface & the sensors.
I pulled a front wheel off and appears that I would need to remove the caliper & rotor to access the sensor for removal.
Has anyone been successful at removing the sensors, cleaning the mounting area and re-installing the sensors to cure the problem? Need to do all 4 wheels or does it primarily affect the front wheels? Can the sensors be removed without damage to them??
From what I have read on this forum, an inspection of the brake lines seems to be in order, as here in WI and the use of road salt in the winter can only accelerate the corrosion of them- I don't recall the brake lines on my late '80's & early '90's GM trucks having this problem of the lines getting rusty, but had noticed it on all of the 2000+ model year trucks I had, just never had them long enough to replace them.

Looks like GM hasn't made any improvements in later year trucks. What will it take to get them to correct the problem, it is a safety concern after all!!!!
Where I work, we have a Chevy Express van and the ABS control module was junk in only a couple years (with only 20k miles!) as it is located under the truck along the frame rail, great design to get soaked with water and road salt in the winter in WI!
Can't blame people from turning away from GM vehicles.
Now the new brake lines are rusting again. I am afraid that the lines might blow out without warning. I am concerned about my safety & others. I have filed a complaint with the US DOT NHTSA. The ODI # is 10358067. http://www-odi.nhtsa.dot.gov/complaints/. I think that GM should be responsible to replace these inferior brake lines at no charge. They should use a better quality (stainless steel) brake line so this won't happen again in the future. Does anyone know if the if the 2011 Silverados have the plain steel brake lines or have they upgraded them. I will also file a complaint with GM and possibly consumer affairs.
Does anyone know anything about this? Any help here will definitely be appreciated. I'd really hate for wife to go rolliing out in front of a big truck or something... Thanks in advance.
The following week I was called and asked if I could have the dealer do an Estimates for the repairs because the estimate I gave was from an auto body repair business for $3500 and was told that because it was more than half the value that they would have to buy it from me and crush the truck and that I "didn't really want my beautiful truck crushed, did I"? Remember I need a vehicle. I said ok and called the dealer to set up an appointment. No problem. Now a month goes by no word. Finally I get a call that tells me that after their review that because I had removed the fuse that they could not verify that the ABS was in fact at fault in the accident even though there tests showed that it did do it with the fuse in and that it was final and came from way up high in management. I asked for phone numbers for these way up high managers and was refused, that the decision was final and that was that. It doesn't matter if I had hit a tree or rolled into an intersection with a tractor trailer going 60mph through it. I asked to see the report that they're basing this decision on and was - can you believe - denied. Whats the big deal it was just a "slow speed impact", right? I was also told that they won't replace parts that are "DESIGNED to FAIL". Makes you feel good that they admitted to making crap thats unsafe. "What would you expect on a truck with over 156000 miles on it, these parts are designed to fail"? I would think that safety parts like brakes, steering, suspensions, and wheel bearings that hold wheels on should out last drive trains and so on.
Just so you know the dealer I went to was helpful. GM is the one I have a problem with
How's that for great customer service from a company that I will Probably never buy from again
hope you enjoy my story and learn from it.
Amazes me that alot of truck owners are smarter than the mechanics at the Chevrolet dealership.
Dont get me wrong, I have always loved Chevy trucks, but when this one dies, My next truck will either be an OLD chevy, or it will be a Honda, or maybe an old toyota.
Thanks to all who helped with this problem, and hopefully anyone that owns a Chevy, will see these posts and not spend a fortune to fix something that only cost me 54.00 (Although i spent 140.00 on a booster that i did NOT need, mechanic said it was the booster, "YEAH, THATS IT" duh!!!) HATEFUL JIM !!
GM said to bring it in and look at it, and "Maybe" fix it, i was looking at 1700.00.
Other than the 140.00 to change the booster, it would have only cost me 53.00 for the bearing.
I've been a proud chevy owner too, for about 30 years, but my next truck WILL NOT be American made, ( I have always said to BUY AMERICAN, but when american companies build things to wear out, they are telling me that they dont want my business. ITS NO WONDER AMERICA IS GOING DOWN THE TOILET!!
Now on with the description of my issue, it feels as if though I don’t have much braking power after the truck has been sitting for a long period of time. For example in the morning, if I were to press the brakes hard say at 40mph the truck does not have enough braking power to even screech the tires and takes way to long to stop. The initial braking is there, but it seems as if when I get to about half way down and the push to the floor it doesn’t respond. Now I know what your thinking (brake fade), well guess again because if I were to repeat this procedure two or three more times going even fast and jamming the brakes to the floor my braking power only them begins to come to me I had my cousin do it while I instructed him what to do, and he said by the third pull it felt as if it had 40 to 50 percent more braking power than initially. After this doing this even the touch of the pedal and you can feel the brakes grab much better. It totally restores confidence in the braking abilities of the truck
If anyone has any sort of explanation to what my issue may be, or has experienced this please reply back to me this issue is getting the better of me and I don’t like it one bit. Keep in mind that the only things I haven’t replaced are the master cylinder, and brake Booster, ABS Module. I am also running the correct brake fluid.
Thanks for your help.
BTW>>> I'm not a brake engineer, just a guy that has spent the last 8 years fixing brakes on GM trucks.
For the money and time I would replace the flex hoses first.. then bleed, while there i would check to make sure the calipers are free floating.. then I would look at the rear drums for issues, they are also suspect due to rusting components and GM shotty design record with there OEM brake system parts, and the rusting of brake lines. ...
My Brother has a GMC version of you exact truck and is also having really scary issues with his brakes.. 2003 GMC V64.3 extcab. (80k miles), i am researching after-market products now to replace most of the things you talked about. Also his truck is left outside and not sheltered from the elements like my truck.
After Edmond's does its WEB face lift I will post the work and the mods we did and anything we discover..from my brothers truck. I fear his brake lines might be an issue as well. I have just replaced all my solid brake lines with the kit from Classic tube....good thing they were about to blow, after I got all the parts back from the dealer i went through them...several spot were rusted and when i bent them and stress then they fell apart on my hands....
last: I know I care for my truck, three mechanics guys at the dealer offered to buy it once i wanted to get rid of it...one said it drove like a new truck and was tighter than the ones they are selling now...hmmmmm must be the bilsteins i put on 80k miles ago
I'll scan in the receipt and send to you if you want (tedtaupier@att.net)

I also have a 2003 Sonoma with 19,000 miles on it. The rotors rusted out and GM refused to do anything about it. It is stil under the 7 yr/50,000 mile GMPP warranty.
In all honesty I will never ever buy another GM product again. They make very cheap [non-permissible content removed] parts that are doomed to premature failure and then do noting to stand behind their product.
FYI: my 4wd just took a dump today with 6" of snow and I still have an anti-lock brake that activating at less than 5 mph(been a 4 yr issue). Next truck will be a Toyota
I am ready to take this to the auction as i would never want to sell this to someone knowing the problems.
Is there anything I can do my self, parts to replace, etc for this? I know the brake lines are another issue to deal with. Have not had the lines break yet ! Thanks
I checked everywhere on this, but no one knew what to do, til i found this forum. I ordered a set of wheel bearings with the abs sensors attached on Ebay. They were alot less than the chevrolet dealership. I put them on myself, hooked up the abs sensor hook up, and they work perfectly now. No braking problems at ALL. Just wish i had found out earlier before i got that new nice bend in my front bumper, and bent curtain that goes into the tire well.
Do change the wheel bearings, This is an accident waiting to happen.
The way it was explained to me, at slow speeds, the bearing Wobbles, this causes the ABS sensor to get confused, and when you brake at slow speeds, the abs sensor activates, so you have NO stopping at ALL.
I assure you that this WILL fix your problem. For your own safety, check the bearings.
Would appreciate any feedback on the probability (likely/unlikely) that the rear brake shoes would be worn to 15% at 48K miles. I've always gone through about 2 sets of front pads for every rear shoe replacement.
So I took it in for front pads (not squealing but figured I was close with the mileage and it was a convenient timing) and asked for a check on the rear shoes. Call back was that the rear shoes were worn down to 15% and needed replacing. Seemed like too much so I said I'd like to come in and look. Got back to the shop around closing, front job had not been completed so it was still on the lift with rear drums removed for me to take a look. Sure enough, they were worn down. Asked if that was a little early and they said yes but no explanation as to why or any other concerns with other rear brake components.
I asked to see the front brake pads that had been removed. Since I had preauthorized their replacement, I never got a read on how worn they were and I wanted to compare assuming front wears quicker than rear. They had thrown those away. Guess that's normal but they would have been nice to see.
So I'd appreciate opinions on whether I'm making too much of this or... Should I be concerned that they told me they needed replacing when they didn't and when I said I wanted to look, they had time to put on worn shoes from another vehicle for my inspection.
I'm having the rear shoes replaced. I've asked to keep the old ones that I inspected and they will be removing. If I should be concerned, is their any way to tell whether the old shoes are original parts to the truck?
Thanks!
Boy was I stupid!!!! :lemon: :lemon: :lemon: :lemon:
My next truck will be a HONDA. Wife has had 2 hondas, the first was totaled from the back, [non-permissible content removed] was in the back seat, SHE DROVE IT HOME!! This one is still going, and going, and going, and going!!
I continued to use it and brake rotors would get hot. It was making a lot of noise, so I took iot back. They replaced front wheel bearings. Drove it 16 miles and rotors were hot again.
What's up?
