I am not sure its the front rotors and calipers ...are a problem.. but rather the symptom. I have put new rear calipers from SSBC on my 2003 GMC Sierra, not sure it matters what type, but rather the rear calipers are swapped for something that works. I also added brake SS-lines. I drive in Boston traffice weekly and have for about 35-45k miles on top of the 45k i had when i need to replace the brakes. NOT one issue, and often times atleast once a week i use them and I mean HARD.
Whith this said, the front rotors warp due to too much heat..the back brakes were not pulling their weight. This i suspected because my wifes old car.. Honda Accord ex stopped on a dime. i actually felt the difference in the rear wheels having more stopping power on the honda.
I saw the on line forums and notices everyone having stopping isses, however the front brakes on the truck created tons of dust, non on the back wheels, I use a little logic, my wife's rear wheels always had to be cleaned disk brakes. Hmmm can you see where this is going..
a friend had a 2500 silverado..had to do a complete brake job, noticed the rear disks not being used and rusting over, a friend of his the mechanic, in his army unit repairs chevy's, told my friend about the rear break caliper defects, it was talked about in a chevy trainig class....hmmmm ..well here comes rear SSBC calipers...there i go. have you guys noticed the Toyota emphasis on heavy duty breaks...stopping the truck before it goes over the cliff...that is not an accident in Marketing.
new rear calipers should fix the back brakes, and front, and the warping...not sure the dealer will pay for it...since they have had training for their mechanics for 3-4 years about the issues .... Until some folks die the NTSB won't get involved which means GM will only loose money by assisting the repair. Why loose money when the public will pay for it, and add service revenue to their bottom line.
This was more than .02, maybe .03,,,was i sick to buy $1500 in brakes...all i know is when i drive my 20 month old son around..i would pay 10 times that for peice of mind.
MY OLD POST>>>>I know from personal experience from yr2000 and on, GM has always had warping issues, I now have 34K miles on my after market SSBC components and no more warping, SSBC.com is probably your best bet, they have rotors that are coated that resist rust.
I now have about 45K on my truck and bakes and rotors are fine, dealer serviced said their 10% used, means I will get about 150k miles before the next brake job... see my photos http://www.carspace.com/ttaupier1/Albums/2003-5_3truck/

Okay, hereís where Iím at.
After looking through my receipts, it appears Iíve already replaced the Rear Rotors and Pads ~15000 miles ago. So I went to the local Car Quest and bought after markets Front Rotors and Ceramic brake pads. Lady behind the counter told me any pulsation on the brake pedal is the rotors. Also talked me into ceramic pads (no brake dust on the rims). I hate cleaning my rimsÖ
So yesterday I replace the Front rotors and pads, and took the truck for a ride. Still have the same problem.
However, it does this less now. For example, it only used to do the ďbrake pedal pulsation/shudderĒ on soft stops under 20 mph maybe 9 out of 10 times.
After changing the fronts, it seems to be doing this only on soft stops under 10mph. And maybe only happening 7 out of 10 times.
So the short version is, itís still doing this, but by replacing the front Rotors and Pads, it seems to be doing this less.
Could there be an ABS problem?
What are the symptoms of ABS problems?
Not sure what else to check.

An update to the brake concerns I have with the 06 Sierra. Took the truck back to the dealer and they were very good with recognizing my brake issue. End result they shaved the rotors on the front wheels, test drove it and sent me on my way - no charge. Got what I wanted, for now. Will wait and see how long this lasts. Makes me think that this is a common occurrence with Sierras. As this is a warranty item, I will be watching it closely near the expiry date of my warranty, in case the pulsation issue needs to be looked at again.
Should I need to replace anything after warranty, I will probably go with SSBC parts if I can get them.

Could it be your calipers? If not mechanical, a sensor maybe? Not likely ABS. I know I need to hammer my brakes on my 06 Sierra to get ABS to kick in. But from what I'm getting from the forum, it looks like all the GM mechanical brake parts are suspect.

Calipers? Iím not sure. I was going to purchase those too the other day, but the lady behind the counter convinced me that it was the rotors. Now Iím hesitant to replace anything else unless I get some sort of reassurance on what it might be.
Iím also hesitant to take it to the GM dealer. Had an issue with them a while back on a recall that they said they would fix, then decided it was my fault (faulty tail gate cables).
So Iím still a little bit upset with them right now.

When I had installed ceramic pads, there were specific instructions on how to burn in the pads. Failure to burn the pads in properly could cause a variety of problems. Course I thought that it was nonsense. But then again better safe than sorry.
I remember that you had to do almost complete stops from a variety of speeds. BTW, the instructions came enclosed with the pads. Raybestos I believe.

Jack up a front corner, remove a wheel, and grab the rotor and test for any loosenes or shake due to a bad wheel bearing, or steering components such as ball joints. Then do the same to the other side. It's cheap and fast and might eliminate (or identify) these parts as the source of your problem. Does it have a hydraulic steering stabilizer? If yes, check that too.
#44 of 618 brake problems on 2007 chevy silverado diesel
Sep 07, 2007 (6:35 am)
I have to put the brake all the way to the floor to stop. Dealer says his computer shows no problem. GM Rep drove it and told me it felt fine to him. He is about 5'11",250 lbs,and a size 13 shoe. They had me drive the 2007 with new body style and there was no problem with me using the brake. They then told me that the brakes are different on that vehicle,because they have a different part number. Next week the dealer told me he would bleed the brakes and take off the wheels and check for problems. If they couldn't find anything wrong,I will have to get used to the way these brakes work. I only have 4800 miles on this truck,but it scares me to drive it. Has anyone else had a problem with brakes? I have this feeling that since I and a woman they can say anything and I should believe them. That is why I am asking for any help. Thanks

The Chevy and GMC (GM trucks)trucks have had break problems since 2000, see my other posts...I am assuming you have read these.
My take is that the front brakes are okay, its the back brakes that are not functioning properly. This issue "not really great breaking" has to due with the rear caliper manufacturing process and overall design of the rear calipers. They are either not assemble correctly at the factory/supplier or not tested for stopping distances.
It seams that this issues only effects a few hundred out of thousands, the rear calipers are probably not squeezing their share of the load. This is the exact problem i had and, like you was told to get used to it...
Thats when i selected SSBC calipers for the rear, and replaced the rear calipers (at my expense)...I have no breaking issues, my wife is 5,7", 130#s says it feels like a nascar and stops better than most cars she has driven..
Take the car back and ask them to take the vehicle back....hmm i would be interested in hearing their response when you tell them the Toyota-tundra comes with heavy duty brakes...and that's the vehicle you want to be driving
