Glen,
I had a similare problem a while back. There was an odd bumping/scraping
noise comming from my left front wheel area. When I removed the wheel and
inspected the brakes I found that the disc seemed to be slighltly warped
which was causing it to hit one side of the caliper every revolution. I
also disvovered that my calipers were not moving when the breaks were
applied. Bled the system and still no movement. So I dismanteled and
rebuilt the calipers (really just the pistons is all that is rebulidable, a
couple of gaskets and a dust seal!). Added new break pads and all is fine.
I still should replace the rotors but all is working fine so once again my
moto is if it ain't broke don't fix it!!
PS Not to question your intelligence but if you should decider to rebuild
the calipers, please do both sides! I have made the mistake of not doing
both sides of a repair in tha past and you end up doing it anyway!!(it was
rear wheel cylinders).
Good Luck
