When you say itÆs out of alignment it kind of sounds like your pins are frozen up and the caliper canÆt slide over. Sometimes you can pry the caliper off the pin if they arenÆt to frozen, then wire brush the pins if there not bent, then use allot of anti seize on the pins to keep them from locking up again. If it wont come off that way unbolt the piece that holds the caliper pins, 2 21mm bolts I think, then you can try to get them free with a vice and hammer.
