Adjust the shoes out to where the drum barely fits over the studs. You don't want to have to force it on or have the pads dragging on the drums, but you want them as close as possible. The further away those shoes are, the more travel it takes the wheel cylinders to engage them. The further they have to go, the less pedal you will feel. Often times when a driver complains of a soft pedal, it's because the shoes are backed off too far. After you get them where you want them, use a hose clamp on the adjuster so it won't self adjust. This is a maintenance item to keep up with every week. They constantly need adjusting.
