Original PIAGGIO spare part in the usual good OEM quality.

Here an overview of the force applied to the brake piston when combining different calipers and pump combinations.

In general, an increase in the size of the slave pistons with the same encoder pistons always results in an increase in the braking force, although with a longer lever travel.
Conversely, when installing a brake pump with a larger piston but the same brake calliper, a decrease in the force applied to the brake pistons can be assumed, although with a smaller lever travel. Thus the brake becomes more direct, but requires more lever force for the same brake performance.
