One way to tune the master cylinder is to insert a washer behind the clip holding the piston in the bore. The thickness wants to be gauged so the recuperation port just about remains uncovered. By minimising the travel before the piston gets to the other side of the port means the pressure starts building higher in the pedal travel. Also the pedal free play wants to be at the minimum for the same reason. Caution is required though, because too thick a washer or no free play will stop the recuperation port from working and make the brakes stick on when things warm up.
