65 Wagon Front And Rear Brake Question

I may not have turned the adjustment out far enough.......Thats a REALLY good recomendation. I had not thought that the brakes would have worn a grove into the drum, Well actually I would never imagined that someone ( previous owner) would let the neglect get that bad that there would be an opportunity for a grove that deep to form..........DEFINATELY will back the adjustment out ALOT farther tomorrow at the Base AutoHobby shop. Thanks for the Idea........On that note though does ANYONE know where to get a good set of drums and shoes for this in the event that these are so bad that they cannot be turned?
