warping rotors?

[97scoob]

well, i have this problem with my brakes...

let me start from the beginning. when i got my car, i could see that the brakes werent in great shape. i put all new pads and greased and cleaned everything and they seemed to work fine. then, not too long after, i could feel my otors starting to warp. i went and got new rotors and pads thinking nothing of it, but then when i looked at the rears, there was buildup all over the rear rotors so that to me meant that they werent working. i tookit to my uncles garage, and they took everything apart, cleaned and greased everything, and put the new rotors in and everything worked fine. now like 2000 miles later, the front rotors are SOOO warped that the steering wheel shakes violently when i hit the brakes. i wasnt slamming on the brakes all the time or anything, i was trying to brake them in correctly, and i always downshift before i brake... also, after driving, the front rotors feel waay warmewr than the rear...

I am assuming that the rear calipers arent working to their full ability, and the front are working harder and heating up the rotors which is warping them. does this make sense to anyone? or can anyone think of another reason this would happen? i really need to fix this because they are getting really bad...

Braking is almost always 70% front 30% rear. There's more weight in the front.

You have most likely not bedded in correctly from the beginning and you now have hard deposits on the rotor material. If your pads are still evenly worn, get some new rotors and bed them in properly.

Also check to make sure your lugs are properly seated and torqued.

There's lots of articles on the web, and the pad/rotor manufacturers have their own instructions, but this is pretty good:
