Most modern disc brake systems use the seals as a means to retract the pads from the rotors, although very slightly.

You could use a laser thermometer to check the temp of the individual wheels to see if there was any wheel that produced higher temperatures than the others, which would indicate excess brake drag or a potential wheel bearing problem.

The newer sealed type bearings do have additional resistance compared to the older type that are precisely adjusted for lower resistance, but that is not the case here.
