I noticed that when I brake during highway speeds my wheels shake indicating the rotors are warped. But it does not shake in city driving. I know brake systems pretty well and i think the reason it does this is the pads are rubbing on to the rotors heating them up causing the rotors to feel warped when I brake. The caliper sliders are sliding ok so I know thats not whats causing this. The only available pads are metallic or semi-metallic. i prefer non-metallics even if the wear faster. At least they are easy on the rotors.
Any thoughts out there to help aliviate the rubbing of the pads to the rotors?? Thanks.
