Brake Shudder

[tfeyerabend]

I have a 2007 NBS Silverado with about 13,000 miles that shudders quite a bit while braking downnhill, but really noticeably when I'm towing my small 10' trailer (not sure how much it weighs, it just carries a race kart and tools, can't be too much). My '99 Silverado with 225,000 miles never had any issues like that, still doesn't. I've had the truck since May and it seems to be getting worse. Could this have something to do with ABS or the rear drums, has anyone else experienced anything similar? Thanks for your help.

More than likely its your front rotors. GM has been putting some cheap ass rotors on these trucks for the last year or so. I just had my 06 repaired not long ago with 15,000 on the clock. It was a weird feeling and I thought it was the rear drums but it turned out to be the rotors were warped.

Yep I have an 07 Sierra doing the same thing. I had the rotors replaced and it is doing it still... Im pissed.

I have 16600mi and mine are starting to vibrate but I thought that it was due to some of my 100-0 MPH stops.

surprised that those rotors didn't disintegrate into dust from that kind of pulling...

No, They work surprising well. I don't do it to much just when someone is messing with me on the road, and are unsuspecting of the tune and no speed limiter.

im on my second set of rotors on my 2005 and its starting the vibration again while brakeing. i even had to replace a caliper when i replace the rotors and that was when the truck had around 25000 on it or so. Its now got about 64000 on it and getting bad again...'bout enough to piss a guy off

Here's the checklist of possibilities I know of:

Disc warped/overheated

Calipers warped/loose/bent

Wheel bearing going bad

Just had a friend snap a balljoint that was doing the same shuddering at braking along with clunk at full lock turn.
