Drums do stop great... as long as you never drive thru a city during mild or rush hours, or follow someone thru same when they have discs... which leaves you a very small window in the cities I've been in... esp if the drums are thin.
Most techs do tend to overadjust, due to bad training, and we dont match shoes anymore. The AMA specs give a decent adjustment procedure without the tool, which is worthless anyway with bent parts... except it can help with diagnosis. If they aint bent too bad the AMA specs work great anyways. Merv can give you better detail on the procedure though.
