Though I plan to replace the shoes on both sides the right side is worn a lot more due to a faulty adjustor on that brake. A notch/shoulder has developed in it which causes the front static end of the upper brake shoe to ride against the drum even when the brakes are not activated. So after only 63 years of service I'll have to be replacing the adjustors as well.
Boy, what cheap parts; you'd think they could make something to last!
Although, having *just* turned 63 myself, I'm thing that a few of my
adjusters are getting worn out too...
I must agree with Bob; brake friction materials__pads/shoes__are always sold, and should be installed as axle-sets. Unless there is virtually no wear__as in less than a few months in service__I treat tire replacement the same way (my wife's X5 's tires have an unnatural, yet magnetic attraction to drill-screws, since there's still a lot of construction around here...).
