    I don't think Topper's link is going to help you much. The early '50s Studebaker adjusters were quite different.

    Without getting in to much detail, the round plug through the center of the shoe always rides on the same plane against the drum as the brake lining material and, as that material wears down, the drum pushes the plug towards the adjusting mechanism on the back of the shoe. The plug is attached to the adjusting lever and, as the lever is incrementally pivoted by the motion of the plug, the wedge, which is under spring tension, fills that slack, preventing the lever from returning, and incrementally maintaining the minimal distance between the shoe lining and the drum. In theory, at least if everything is moving properly, you have a constant perfect adjustment.

    self adjusting brakes on my '52 Commander

    I consider myself "mechanically inclined", at least I have always been able to fix things when needed and figure out how things work. However, the self-adjusting part of the brakes on my '52 Commander have me puzzled. I believe(?) I have all the parts, and everything seems to work freely but I cannot see how they self adjust themselves. The brakes on mine are all new and working good but I still would like to know how they work. I have the genuine Studebaker brake manual ordered but it has not came yet. Can anyone 'splain them to me or direct me to a good source of info on the 'net in the meantime? thanks
