I replaced the brake hoses.  Problem still persists.  But please
notice that in my story about my trip to the air****t, I did not use my
brakes for like 30 miles of hte trip since there was no traffic on the
highway at 3AM.  But, at one point, without using my brakes at all,
the problem started.  It starts as you notice more gas pedal effort
needed to move the car (dragging), then the vibration starts gradually
and builds up in intensity.  I can only assume this might be caused by
the wheel getting hotter and hotter and eventually heating up the
tire.... does this make sense?  could it be a brake booster problem?
