Also it may just be the piston seals sticking and keeping the pads from releasing a little bit. If that's the case then strip the calipers, clean the pistons and caliper down (degreaser and an old toothbrush do a great job for this). Make sure they are thoroughly flushed and 100% dry before reassembly. Grease the pins and put them back on, the problem should now be gone, and while your doing this you might as well just replace the old pads too.

If it hurts, you aren't doing it right.
