<VV> mystery rear brake noise, need help

[HallGrenn at aol.com]

Ray,
 
Look for shiny metal first--on the inside of the drums (not just the swept  
area but the steel part too), the backing plate and the individual pieces 
of  brake hardware.  As you may have mismatched parts you might be able to 
find  the one part causing trouble and then replace it without replacing all 
the  hardware with the correct pieces.  Best of luck,
 
Bob

I think  I might have accidentally used 62
brake hardware (springs and the little  retainers) which I see are a
different part number, but if so I'm pretty  sure that's only on one side
and both sides are making the squealing  noise.  Not sure if the grinding
noise is both sides as it is very  intermittent.

What should I be looking  for?
