I'm not sure that I follow this properly, however, is it the idea that one
drills a series of holes vertically near the leading edge face of the shoes
and inserts bits of graphite pencil leads?
If so, then isn't the efficiency of the braking system compromised because
after all, graphite is a lubricant?
I reduced brake squealing to next to nothing by chamfering the leading edge
of the shoes to a 30 or 45 degree angle on the advice of someone who had
dealt with similar problems in MG's.
