OEM brake pump from PIAGGIO supplier Heng Tong.
Superb optics, as the whole unit is polished.
Thanks to the strict PIAGGIO quality control, this is an absolutely recommended part.

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

In general, if the slave pistons are enlarged while the encoder pistons remain the same, there is always an increase in the braking force, although the lever travel is longer.
Conversely, if a brake pump with a larger piston but the same caliper is installed, a decrease in the force applied to the brake pistons is to be assumed, although the lever travel is smaller. Thus the brake becomes more direct, but requires more lever force for the same brake performance.
