I've been running BB7s with 160mm rotors for a while but just moved to a 140mm Ashima Airotor in the back. The brake pad is too far out relative to the rotor (by about 2 mm), so the outer edge of the pad is not touching the rotor at all. What's going on? Maybe the rotor is undersized (sorry, should have measured but I was too lazy) or my 140mm IS rear adapter is slightly oversized. I think it's installed in the right direction, but here's a picture in case I'm missing something.
Any fixes? Should I face the adapter? Or maybe the flat side of the lower CPS washer? Thanks in advance for the help.
