It's been 40 years since I've done a brake job on one of these but I thought the brake line went straight to the wheels from the m/cyl. The shoes are "dry" unless there's a problem. One thing I do remember is that you don't want to do a brake job if there's any possible way to trick some other mechanic into doing it for you. It involves pulling the final drive and possibly sacrificing chickens. The first time I lifted a final drive up onto the bench by myself my back went out for a week. The next time the shop foreman tried to assign me one I faked a head injury and pretended I couldn't speak english.
