I agree with carl 100%, but to realize the wear-in scenario, the shoes should probably be tighter than 7 clicks loose to start. Wherein; wear-in will be much faster than waiting for 300 stops and you will improve stopping right away.
I have never admitted this in public before. I have always done my own brakes. Probably over a 60 times on over 30 vehicles. I have never turned the drums or machined the rotors. In keeping with Carl's comment, I not only let the curvature wear-in but I let the grooves in the drum/rotor wear-in to the shoes/pads. More surface area for friction! Or I'm cheap. Forgot which. Please do not follow this method. Keep the economy going. I will join a focus group. Thanks.
