I think this is how they are adjusted on our cars but im not sure but here goes, when you pull the e-brake it has like a gear inside the calaper that moves the piston out to engage the brakes and i think if it moves out enough it adjusts the piston so it takes up the excess travel so when you push on the brakes it doesnt have to move as far and the brakes engage with less pedal travel since the piston doesnt have to move as far before the brakes apply. Once again im not really sure if that is how ours work but at least i tried.
