Measure or have someone measure the LRO (Lateral run out of the rotor), the bolt face to rotor face should be true to less than 30 microns at top pad edge contact area of rotor. Yours must be horrible. Hi LRO is the main cause of shudder, brake dust and fast pad wear. Always clean the rotor and knuckle mount surfaces after separation.

I just filed my complaint.....
 
My 2002 Chevy Silverado HD 2500 has severe rust issues for certain components. On 5/16/2009 I had a steel brake line burst because of rust damage. Upon inspection I noticed that all brake lines had significant rust damage. General Motors has no part number on these steel brake lines and cannot supply a replacements. In addition to rusted out brake lines I have the following other rust issues, Severely rusted drive shaft, Severely rusted front rotors, (I had to replace the rears last year), Severely rusted washers on body mounts, Severely rusted transmission casing and the Frame starting to rust out. In my onion GM has a major quality and safety issue here. I contacted Chevrolet about the rusted brake lines and they blamed the problem on road salt. However other components under the truck and the truck body itself look great. I believe that GM used inferior materials in certain components resulted in these parts rusting out.
 
I'm planning on using right stuff detailing to make my new brake lines.

In my experience with many warranty issues with my GMC, gmmaster is right on. First you get a good dealer that appreciates your business, be fair with him and they will treat you fair as well.(I'm sure it doesn't apply to all) My dealer always tried to do their best and I could see when GM was the cause of the hold up, but the dealer still worked with me. My biggest complaint is with GM. They send a comment card, ask all about the dealer--- the dealer is awesome --- it is the Truck! But, no one apparently reads those comments cards or cares. Simple Secret-- learn from your customers and mistakes and fix them! Customer comes back! No excuse for the same technical problem, that can be resolved, to exist for 6+ model years, while producing the same problem replacement part. Kind of sucks if you have to replace the part ( warranty or not) and know it will only go another 10,000 miles or so ( eg steering shaft.) geez i wish GM would read this. You don't need no f***king overpaid consultant to tell you what's wrong. The answer is under your nose---- talk to your customers! Sorry about the rant, but I really want to buy another GM, if they would just fix these issues, it's not that hard.

The GM board just got rid of Wagoner. Can't believe how long he lasted losing so much money. That's what GM is good at. Making a product no one wants. The Aztec comes to mind.
 
No matter as everyone deserves a 10th chance as GM is getting. We shall see what the future holds. At one time all three of my vehicles were GM. Now two of them are and by the end of the year only one. Course I'm not giving up the vette. Trucks are another matter. That 5.3 is really old news even with the AFM.

1995 GMC Sierra brake line replacement by ellis5464
Jun 30, 2009 (12:23 pm)

I have a 1995 GMC Sierra truck. There is a hole in the brake line near the gas tank. I can't access the union/coupling in this area because it is too tight, the gas tank is in the way. Is there a way to get to the union/coupling without removing the gas tank? I have been soaking the union/coupling joints for 5 days with solvent, but I still can't get the wrench on it. Can I run a line down the entire body instead of removing the original sections?

I just did this yesterday.. I was able to undo the frame clamp on the rear section of brake line and pry the line just above the tank to get a wrench on the union. to work on it I had to cram myself between the exhaust pipe and the drive shaft to see above the tank. Once I go in there I was able to remove that piece of brake line from the union to the bracket above the axle. mine rusted out, fab a new one and slip it in from the back.

ABS issues by kerryj
Aug 02, 2009 (5:06 am)

Hi folks, I have a 2006 Sierra that has a problem I see described in a number of posts. ABS seems to be kicking in at very low speeds. This started at about 80,000 miles. (has 88,000 now). I have described the problem to 2 different dealers and both said they have never heard of the problem. After reading all these posts, I find that hard to believe. I am not really interested in disconnecting the ABS. I just want to fix it. Will cleaning the sensors actually fix this? If so, has anyone done this and how difficult is it. I'm not a professional mechanic, but I do know my way around a vehicle and do most of my own work. I considered changing the entire hub (I'm told the sensor rings are housed there) but they are $515 each.
Thanks in advance.

Hi There - I just started having the same exact problem with my '06 Sierra and the peddle seems to get more "spongie" with the ABS kicking in at inappropriate times (i.e. very slow speeds and when the wheel turns at slow speeds...into parking spots, etc.). I will bring to a shop to get diagnosed this weekend and post when that's done. Please keep me posted w/ any info you might find. Thanks!!

February 14, 2006
Owners of General Motors trucks and SUVs in 30 states not covered by the GM regional recall continue to struggle with malfunctioning anti-lock brakes. Owners in the 20 states and the District of Columbia covered by the recall are struggling with GM dealers reluctant to fix the brakes as part of the recall.
