How to adjust the rear drum brakes

^^^^^ What Trmnator said. The 2 long(secondary)shoes provide more holding power when footbraking. You can also use a larger diameter wheel cylinder from a station wagon or whatever crosses over to provide more power to the shoes. More surface area of the wheel cyl provides more lbs per sq. in of pressure. Conversely less surface area of the master cyl piston provides more pressure. A larger MC piston provides more fluid flow with less pressure. If you switch to dic you most likely will need a larger bore MC. Also check pedal ratio 6:1 is what you want. 12" long pedal you want the MC to attach 2" down from the pivot point.
