Wondering about your problem? I may have the same issue. My front brakes are pretty much on all time I can barely turn the rotor w/ the tires off. I have replaced the calipers w/ another set I had in the garage. Could my brake "freeze" be caused from two sets of bad calipers or do I have another problem. Also noticed uneven pad wear, but I am assuming that could be from my old calipers. Anything sound familar?
