1. Does the truck shake?
2. Does the wheel shake?
3. Does the brake pedel vibrate?
4. Check your tire pressure?

Note: certain rotorwarrenty's, regardless of what anyone says, do have a warrenty... they have to pass numerous tests to make it to the market... after some ware and tear like 28K miles, i would not expect rotors to go that soon, and if so save your receipts, 3+ times with the same problems from the same mfr. and you got some re-embursement $$$here in NY state.

 

I was kinda under the impression that 3 year, 36000 mile bumper to bumper warranty included rotors. I would certainly try it, wada ya got to lose.
