I have a 2006 Ram Quad Cab and need to do the rear brakes this weekend. I measured, and the rotors are already under spec, so they need to be replaced.

I have heard horror stories in the past of different brands getting easily warped.

Should I buy them from the dealer? Or will a NAPA, Autozone, etc. be just as good?

My guess is there are probably a small # of suppliers for most of the big stores anyway.

Thanks.
