Brake Problem
 

As we were putting springs in tonight (pics tomorrow) we noticed that these didnt move like they were supposed to http://i5.tinypic.com/15726c1.jpg. I forget what he called them. But by the time I got home from work I smelled something burning. Well I looked in there and the rotor was red. I guess the caliper is stuck? Do I have to get a new caliper? Anyone have this problem before? Also I bought this car used from a dealer so they should cover this right?
