I had same problem on my Titan brakes and tried the loosen pulling brake thing. That didnt fix it however. After some inspection i realized that the one mounting bolt was pushing the caliper off the position it needed for alligned brakes. I happen to have a dremel and showed that bolt who's boss. I would not reccomend that path of action for anyone not used to grinding. My advice turn bike upside down loosen caliper and check it out carefully while brake held and slowly tightening the bolts. Hope this helps someone.
