Brake pedal travel

You can lose "some" pedal just in the drums. When you machine drums oversize, the shoes are "too small" diametrically. They can actually flex in the drum, or at least don't fit "soldidly" and act as to "soak up" pedal travel. You can sometimes eliminate this while diagnosing by adjusting them up TIGHT. If the pedal seems firmer you are on the right track. Obviously you don't move or drive the car while doing this.. Weak hoses can expand, as well
