Even if the mount was slightly bent inwards the BB7 should be mounted with the CPS/Tri Align washers that allow the caliper position to be mounted on a tilt if needed.

If the rub is coming from the inside pad and if the caliper can't be positioned inwards any more, the rotor can be shimmed outwards on the hub to stop rubbing.
