Here is an overview of the force applied to the brake piston with the combination of various calipers and pump combinations.
In general, increasing the size of the slave piston while keeping the master piston the same always results in an increase in braking force, albeit with longer lever travel.
Conversely, if a brake pump is fitted with a larger piston but the same brake calliper, the force applied to the brake pistons is expected to decrease, although the lever travel is reduced. This makes the brake more direct, but requires more lever force for the same braking power.
