The amount of free throw at the lever is a function of the master cylinder's area and the combined slave area of the caliper's pistons. When using the same MC assembly for the Cura 2 and 4 brakes, the free throw on the 4s must increase with respect to the 2s simply because you need to displace more fluid to move twice the pistons at the other end.
