I am working on 1973 Scout II rear drum brakes. I replaced everything but the back plate. The problem is when I put the adjusting screw on it is too loose. When I tighten the adjusting screw to where it is tight enough so it doesn't move around and put the drum on it is really hard to turn. I did the drivers side with all the same parts it it works fine. Any ideas??? I am getting so close to getting it on the road and I am only one brake away for taking it for a test drive. Please help!!!!
