As with many on this site my front rotor is warped. I want to fix this, but I'd like some info on the problem first. Why is this a problem on our bikes, is it the materials in the rotor, or some issue with the caliper? I'd like to know how I could keep this from happening again so soon. Those of you out there that have had this problem what did you do and with what product? Any info on aftermarket brake parts that anyone here has had good luck with would be greatly appreciated.
