when i got my 92 camry from my mom in november the front rotors were warped and i had them replaced along with new pads. now again after about 7000 miles later they r warped again. im about to redo it but im wondering what can be causing this.

This is fairly common.Sometimes it can be as simple as improperly torquing the lug nuts or rapid heating/cooling of the discs.

Also, I've heard that there can be a problem with the adjustment of the piston in the caliper that causes this.
