Mark,
From your post,I suspect that what you are describing is the grooving of the friction lining on the brake shoe, and then "easing", or chamfering the edges of the grove. There have been many innovative attempts to improve the braking characteristics of drum brakes; grooving the linings, drilling holes in the backing plates or/and drums, all in an attempt to make the things work better. The idea is to ventilate to carry off heat, and water in wet situations. Some of the claims for different approaches are quite optimistic. There is shop in SoCal, an old time brake shop that has been in business since the 1950's that still does this kind of work. He is a very courteous man, will do business by phone, mail, freight, or whatever; said I could get my drums done in about three days, my place (Grass Valley) to my place. He didn't have a web page when I spoke with him, and a system crash lost all record of correspondence. Any brake shop that deals with restorations, or almost any truck brake service should be able to give you more info, or answer your questions. Contact me by e-mail if you would like, and I'll see if I can find the stuff on the shop in SoCal.
