-- This is one area that I have had some experience and some success. To be sure, rotors warp because of uneven heating and/or cooling. Hard braking is the usual cause but sometimes the same results can occur when an excessive portion of your driving is regularly excessive stop/start. On a previous vehicle I obtained different pads, Kevlar I believe, and this resulted in less rotor wear or perhaps more even wear. I believe that when the rotors are no longer uniformly thick, heating causes differential expansion and results in warping. Malcolm
