Seized calipers are most easily handled with a rebuilt caliper to replace the seized. Otherwise buy a rebuild kit -- dealer may have one with all the necessary seals and bushings, auto parts store almost certainly will.

However, rebuilding it yourself will in all likelyhood involve a great deal of brute force application. Seized bushings are generally not easy to remove, and sometimes impossible this side of a hydraulic press.
