Brake master cylinder -DMP- piston Ø=12.7mm - lhs

Here is an overview of the force applied to the brake piston when combining different calipers and pump combinations.
In general, an increase in the slave piston with the same master piston will always result in an increase in the braking force with a longer lever travel, however.
Conversely, when installing a brake pump with a larger piston but the same brake caliper, a decrease in the force applied to the brake piston can be assumed, with a smaller lever travel, however. Thus the brake becomes more direct, but requires more lever force for the same brake performance.
