#500 of 611 '08' sierra rear drums grabbing
May 15, 2012 (12:46 pm)
The initial problem was the truck shuddering while stopping so I changed the front rotors and pads to slotted and drilled rotors and ceramic bads. This did nothing to stop the shuddering, so I took it to the GM dealer and had it diagnosed they claimed the front rotors were warped "extremely hard to believe" i asked the dealer to check the runout and make sure before turning these new rotors. After turning the rotors this still didn't help the shuddering. Dealer did more investigation and came to the conclusion that the back brakes were work out and sticking, so those were changed and the drums turned. Still didn't help the shuddering so the dealer now believes a belt has come loose in the tire and I need to take them back to the tire shop. So back to the tire shop and talked to the tech there, he explained they have an '05' that was doing the exact same thing and its the rear brake shoe's grabbing and he didn't know why. He clamped off my rear brake lines to remove the rear brakes from the system and we tried driving the truck again, this time no shuddering. So took the truck back to the dealer and told him what we found. Dealer did some investigating and found that GM has seen this problem before and that the cause is the center hole in the drum is larger than the flange on the rear axle that it fits over and the drum is not going on perfectly square so when you hit the brakes one shoe is grabbing and the other isn't therfore causing the shuddering. To fully determine if this is the case the dealer will need the truck for 8 hours to mic everything and document it "what do they need the truck for the next 6 hours for?". GM's fix is to replace the axels and all brake hardware to correct the issue.
Has anyone else heard of this or had this problem - or is the dealer full of BS?

It's great that your dealership has narrowed down the potential cause of your shuddering to the drums. We'd be happy to follow up on anything for you if you like; please get in touch via email at socialmediagm.com if we can look into this further (include your name/Edmunds username, phone and address, the last 8 of your VIN and current mileage, and the name of your dealership).

Hey, gmcustsvcsarah, you need to read post 500 AGAIN. GM didnt narrow down the potential cause of the shuddering!! GM was TOTALLY in the dark, and couldnt figure it out, after turning a BRAND NEW set of rotors on the front, working on the back, and as usual- finally BLAMING IT ON THE TIRE MAN.
The way i read it, not only did the TIRE MAN "narrow down the potential cause", He figured it out, which turned out to be a "MANUFACTURERS DEFECT", WHICH STATED IN 500 GM stated that they had "SEEN THAT PROBLEM BEFORE".
AS usual, GM builds faulty trucks, then blames everyone else when they cant figure out what they did wrong!! DEFECT- I DONT SEE NO STINKIN DEFECT!! WELCOME TO THE WONDERFUL WORLD OF OWNING A PIECE OF CRAP GM PRODUCT- HATEFUL JIM SAID THAT !!

Hateful JIM here- If I was you, I believe i would make GM buy me another set of FRONT AND REAR drums, seeing as how they turned both down, and cut off perfectly good wear on a set of drums that DIDNT NEED TO BE TURNED. NICE to know that GM is sooooooo good to experiment on your truck, AT YOUR EXPENCE, when they have NO IDEA what they're doing, or WHAT the problem is HUH??
SURE AM GLAD I BOUGHT A CHEVY, AND NOT ONE OF THOSE D--NED FOREIGN JOBS THAT LAST A LIFETIME. I SURE SAVED ALOT OF MONEY BUYING AMERICAN, wait a minute, that dont make any sense, forget i said that. Have a great day, Hateful Jim said that!!

Mine had contaminated fluid too, never could figure how that happened. Go back some more posts, a few different answers, mine was ABS system went bad, After I changed everything, end up pulling out ABS fuse. no problems since, 3 yrs ago.

If you have a hydroboost system, have you bled that? You have to lift the front of the truck in the air and turn the steering wheel back and forth about 20 times. You'll need to check if the engine needs be on or off. Worked for me, though my pedal would get soft again after a few months. Heck, it came off the dealers lot with a soft pedal. Never had good brakes on my 03.

My 2002 Siverado Z71 4wd with 70k on the odo now has the infamous anti-lock shudder, caused by corrosion. I pulled the fuse as a temporary fix, before the truck kills me or someone else. Called the local dealer, who also services my CTS wagon. Their response: TS, the recall was done in 2006 and GM has no further responsibility for their crappy design. I had a out of warranty issue with a Toyota T-100 at 77,000 miles. The alloy wheels were blistering from the salt used on PA roads. Toyota paid to have all four wheels powder coated.

That type of response is highly disappointing. What type of corrosion caused the issue?
