How can I get an air bubble without opening the system?

Cool - it seemed like almost everyone I read about having this problem the caliper compressed where the pad is contacting the rotor. So it seems to me like that should cause that brake to be applied until the pad/rotor wears away enough. This is why most say they can smell the asbestos from the pads.

I wanted to correct myself in my question below #7. Applying the breaks while turning the wheel would not help because the good break would hold and you would not be able to turn the wheel on the other side. You could, however perhaps remove the caliper on the assumed good side and do this test.

Well looks like I won't have time to mess with this until the weekend. Anyway i should be able to figure out what's what.

Another thought, the caliper on the left may have an air bubble causing it not to compress properly, making the caliper on the right do all of the work. Good luck
