Both front rotors warped. Dealer turned them and car feels good again.

Curious if anyone else had this problem? Haven't seen any posts. /phpBB/images/smiles/icon_confused.gif

Glad to hear you got your problem fixed.
I would have pushed the dealer for new rotors. They will likely warp again over time.
My two cents

Correction, the WILL warp over time. I had mine cut at 6k miles. At 13k the pulsation was BAD. I then discovered I could minimize it by using a very specific torque sequence. But, the pulsation came back, not nearly as bad but it did. Finally Chevy changed out the rotors for me, and I haven't had a problem since (using the same torque sequence).

Heres the important part: DO NOT LET THE MECHANIC USE A TORQUE STICK AND AN IMPACT. NO MATTER WHAT THEY SAY DON'T LET THEM DO THIS.

Use a torque wrench, step the torque down. And if you use lube on the threads (as you should, but chevy says no), use 85ft-lbs. 100lbs dry. If you use lube, and tighten to 100lbs, you WILL kill the studs.

Thanks all,

I think if it happens again we may try some of those jobs with holes and slots.. Baer

Junk the factory rotors and go for cross drilled and vented rotors, once the factories are warped they are history. If the dealer is lucky turning them might get you through warentee.
