internal handbrake pump for Vespa PX (also Motovespa DN/DS and LML Star/Stella) models. Enables a conversion to a fully hydraulic steering of a retrofitted disc brake, invisible from the outside. This way the typical Vespa look is fully maintained.
Technically the brake pump shines with a piston diameter of Ø9,5mm adapted to the common brake caliper pistons. The smaller piston of the master cylinder optimises the transmission ratio and the brake grips much more bitingly than with a standard brake pump from Piaggio.
The standard piston size of 9.5 mm is suitable for single-disc brake systems with piston sizes of 30-32 mm.
