I haven't gone to garage to verify that the brakes on my wifes bike are bb5's but her calipers have an adjustment to keep the brakes from dragging on the rotors and if you have them set wrong, they will limit the force they can apply and therefore create just the behaivior you are describing.

With the wheel out see if there is sufficient force, squeeze a stick or something about the thickness of the rotor, that will indicate pressure. Maybe some sheets of paper. You may have a binding pivot or cable.
