Here is my perspective, the vehicle issues you have described, have been seen by myself (my eyes),on a truck 2000 HD 2500 chevy, the vehicle was lightly driven and the rotors literally rusted over (both rear rotors).
To describe what I saw was that the rotor was rusting over from the outside >to> inside where one inch of shinny rotor metal was available for seating with the pads and calipers, should have been 2 inches approx. (mind you this was in 2001) his truck was one year old and was not stopping properly. His vehicle sat outside and was at a military base for several months while preparing for IRAQ.
I have had several post to describe the issue, GMC/CHEVY and GM designs with their breaking systems have fallen down. IT IS NOT every vehicle that this happens on just mainly their larger vehicles.
The Dealer tech (for my friends vehicle) said they were trained on the issue and know that it is a QUALITY SNAFU (Situation normal, "all flubbed/fouled up")
I started to see the same issue on my 2003 and felt the less than lack luster performance since day one. I feel the master cylinder is fine and the hoses are okay, pedal mechanics work fine.
I replaced the rear "calipers & rotors- and installed SSbrake lines),
front: i replaced the rotors....had the brakes done 75K miles ago ..and have had NO problem since.
My rotors are not rusting over and brakes work great for almost two years now, my dealer was approach to fix the issue several times, before i took action...they gave me the run around, and laughed at me no doubt after i left the service visit.
I have two small kids and could wait for the truck to have a incident to fix the situation
#75 of 618 severe brake shudder and steering wheel vibration
Apr 14, 2008 (5:20 am)
I have a 2006 GMC Sierra Crew Cab and since the vehicle has had 2000 miles (3500 Kms) it develops a violent vibration / shimmy in the steering wheel during bothe town and highway driving; you can smell the brakes buring, and the rims gets so hot you can burn your fingers on them. The problem happens more on hot days on the higway, and during the winter we don't experience the vibrations as much, but we do still get a metallic burning smell from the brakes.
When the vibration occurs the truck will not accelerate as you can feel the brakes ceasing and holding the vehicle back. The steering wheel literally vibrates 1 - 2 inches each way, and when we apply the brakes to pull off the road the vibration maginfies causing the truck and steering wheel to violently vibrate and shudder, in turn making it very difficult to steer and stop, and the pulsation in the brake peddle is unbelievable; all o fthis while driving at 100 - 120 km/hr.
I know this is a huge safety issue and I fear everything will cease up one day, or I won;t be able to stop safely. I've been to the dealer too many times to count since we got the truck, and they are continuosly replacing / repairing front end brake components as the heat / friction from the problem has caused things to crack and warp. I've asked them to check the ABS module to see if it was malfunctioning, and the dealership can never get the truck to replicate the issue so they don't know what to do....plus it is causing the tires to wear excessively and feather due to the vibration at high speeds.
I know there are brake issues with GMC...I'm at a loss of what to do, has anyone had this problem and was it fixed, or maybe some suggestions or things I can ask the dealership to do...besides replace my vehicle as they aren't interested in that.

Yes this was very similar to my problems (see my other posts/photos). It seemed that the front brakes were doing all the work, I also have disks brakes in the rear. After a few visits to the dealer, and the feeling like i was being laughed . I was torn and loved the truck and my two toddlers. I also notices the front wheels covered in dust but the back wheels hardly ever need to be cleaned... Hmmm?
I went to SSBC.com and bought the rear tri-caliper sets and Russel SS brake hoses kit, mind you this caliper upgrade was for the Rear ONLY...I used the SS brake hoses on the front as well. I also ordered the SSBC.com treated rotors package for all four wheels. I spent about 4 hours by myself doing a side at a time in my garage.
I now have no problem and the truck ...after 50K miles... still feels new even after sitting at the airport for three weeks straight, and no rusting over of the rear rotors
In my honest opinion have the dealer replace the rear calipers....see if this makes a difference and have them buy new rotors and pads for all 4 wheels..... , you might also go to Russel and buy the SS braided brake line kit this will also help the lines from feeling soft, and improve pedal feel, help with better braking habits...my wife has a lead foot when it comes to gas and brakes, helps her feel more in control
I have a huge problem with the rear calipers from the factory, and if i buy another GMC I will request the dealer upgrade the brakes and finance the SSBC package as part of the vehicle costs.
Brembo also makes a kit but with a significant price difference, the SSBC kit allows for standard wheel size and i think the brembo kit requires 18+ inch wheels and tires...
#77 of 618 New rotors will not fit!
Apr 15, 2008 (6:47 pm)
I bought all new rotors and pads for my '01 GMC Sierra. The front fit perfectly pads and all but the back rotors are to thick for the caliper bracket. Is there anything I can do the fix this problem without having to turn my new rotors?

I'm assuming this is aftermarket. If so those companies have been known to ship incorrect parts. I'd call them and see if that's the case before doing anything that might make them "unreturnable".

I am assuming you ordered the correct parts from the web and can not easily return the rotors...or exchange...locally
Not sure if you are doing the work yourself or with help, I believe the rear calipers are needing to be compressed, I cant remember, but I think you have to turn the piston to close them or to get them to close... you might pickup a truck maintenance or brake caliper manual for actual instructions.
Its been two years since I did mine and I don't work on them that often hopefully for another 100K miles. I believe to compress the rear caliper sets due to the design I think I had to compress the calipers a funny way to get the new rotor and pads to fit correctly and meet up (tight fit if I remember). When i replaced the rear calipers they came compressed from SSBC.com factory
I found this on a few sites: For the rear calipers, you will need to turn the piston clockwise(as you are looking at the top of the piston), about one or two turns and then compress the piston as far as it will go, the turn the piston again and then compress again, repeat until you are all the way to the bottom. I highly recommend the Kent Moore brake compression tool.
Hope this helps, I would also check to see if the part shipped was the part you ordered, and the part you actually needed.
Hope this helps

Here is a link to another site tracking some other complaints...maybe there are enough folks to get a class action lawsuit going on behalf of a few million owners
"A "class action" is a civil suit brought by one or more people on behalf of themselves and others who are similarly situated. In other words, the others are in a substantially similar circumstance where the common issues are the most critical to the lawsuit. For example, if a large number of consumers is injured as a result of an allegedly defective product, the principal issue will be whether the product caused the injury. Some examples of class actions are those brought against the manufacturers of allegedly defective or hazardous products, such as asbestos, certain vaccines, Agent Orange, tobacco, and breast implants. Only then will the question of how badly each party was injured be heard.
Class actions may also be brought on contracts. For example, all customers of America Online could claim damages when it went to its $19.95 per month rate - with inadequate capacity to handle the increased traffic.
Another frequent field for class actions is securities claims. For example, suppose a company issues an allegedly false press release and the stock goes from $10 to $15 but when the truth comes out the stock falls to $6 per share. A class action could be brought on behalf of all the stockholders who purchased shares after the company issued deceptive news and before the truth came out. Each member of the class allegedly suffered some harm as a result of the alleged wrong. The damages each member of the class will vary - someone who bought 1,000 shares at $15 each would be 10 times more impacted than a person who bought 100 shares at $15 – but the critical issue is whether the press release was deceptive, and that is common to all class members.
Typical class actions involve hundreds, thousands or millions of people who have comparable claims. Class action "certification" permits all claims to be heard in a single trial."

Since he said rear caliper brackets I'm assuming you won't need to compress those.

#83 of 618 Removing the rear rotors
May 20, 2008 (6:16 pm)
I have a 2005 Silverado 2500HD 4x4 and the rear brakes are completely shot after 24000 miles. However, I cannot get the rear rotors off the truck. They appear to be loose a little bit but something is holding them on. I think it may be the parking brake assembly. How do I get the rear rotors off? Is there something else I need to remove?
