The only time I've seen shoes wear unevenly like this was when the 
drum had worn wrong and had slight taper. or the shoe itself wasn't 
the right width.    Even a new shoe in this situation won't ride on 
the drum correctly and it tries to "tilt" and the aggravation is made 
worse by the slight angle the shoe exhibits to the drum being 
amplified by the wheel cylinder pushrod that tries to tilt the shoe 
even farther.

Of course if the drums were all refaced and true to begin with and 
the shoe is the right width, all bets are off...


But I've seen this same thing several times and each time the drum 
had taper or the shoe was the wrong width.
