Uneven braking/noisy

this is not a repost. it just happens to be very similar to my other one. In my 02 daewoo lanos, i recently discovered that when braking at about 40 down to 5mph, i can feel the clamping force of my brakes wavering. i assume one or both of the rotors is warped. the car has about 4,500 miles on it. also, in the 99 sebring the brakes are very squeaky. they are well past being broken in, i unfortunately dont know what kind of pads its got, but maybe there is a better type you recommend to have installed for better and maybe quieter performance?(for both vehicles) i have my eye on EBC Greenstuff.

Not sure man, but ask Dale Aeppli, he is pretty smart about this stuff.
