Seems that I had this grind noise occasionally from the passenger side
rear brake.  Had the rear end up on jacks to do some work and notices
that the same wheel really didn't have much resistance to movement when
the emergency brake was set where the driver side wheel could not be
moved by hand.  Finally got into the shop and the mechanic took
everything apart and couldn't find any problem.  He tightened up the
emergency brake (to tight in fact in that the lever could not be
released.  The van got driven a little.  There was a stopping vibration.
Took the van back to the shop and they fixed the tight emergency brakes.
Now there is a faint vibration in the rear brakes which I can feel in
the pedal.  Anything I should be looking for in a problem with the
brakes at this time?  Intermittant grind seems to be coming back as does
the lack of emergency brake grab on the passenger rear brake.  Drums and
pads have 77K on them.  What is the life on a set of pads and drums?
Lots of questions here.  Looking for some answers here?
