The single most common cause of brakes squealing after being
relined has nothing to do with the composition of the brake
pads or shoes used.  The problem occurs both with disk and with drum brakes
and is caused by a lack of lubrication.  All metal bearing surfaces
should be LIGHTLY! greased with some high temperature grease.
The best stuff I ever saw was some speacially formulated stuff 
from GM but I have never seen this commercially available.  Moly
grease is fine, so is lithium or white grease.  
Don't use axel grease or that brown wheel bearing
grease; it can't take the heat and will bleed onto the friction
surfaces.  Washing the parts in brake cleaner can only make the
problem worse by removing any vestige of lubrication.
The lubrication should be applied to the little bearing pads on 
the backing plate of drum brakes and to the edged of the pads
the bearing surfaces o

	I have had a similar problem with my '81 Plymouth Champ
	(Mitsubishi). I attributed it to the brake pads also but
	was never 100% sure. At first I thought that I had worn the
	brake pads down to metal but upon examination, I had plenty
	left so I more or less ignored it.
	I can't say too much about the composition of the pads
	although the supplier said I had two choices. One was
	a long wear harder composition and the other was softer and
	would not have as much mileage. I chose to go with the softer
	pad thinking there was less wear on the rotors that way.
