Brake master cylinder (front) -8.1 OTTOPUNTOUNO- piston Ø=11mm, CNC - Vespa V50 Special, V50 Elestart- rhs, silver
Part no.:
BRK190
Description
Brake pump / master brake cylinder -OTTOPUNTOUNO 8.1 CNC Ø11mm- for mounting on the lower part of the handlebars
Clean, solid and simple conversion to fully hydraulic disc brake actuation. No drilling or milling necessary.
The HBZ is manufactured by the highly specialized and ISO-certified tuning forge Ottopuntouno (8.1 for short) from Italy.
Made in Italy
CNC machined
Ø11mm piston
Complete set incl. matching second lever for the clutch
The set is ideal for converting an existing disc brake to fully hydraulic actuation or a vehicle from drum brakes to disc brakes. The set includes all parts for the handlebars, excluding the brake line.
4-piston radial brake calliper
The piston diameter of Ø11mm is perfectly suited to installing a powerful but easily controllable brake. Massive deceleration values are achieved, especially in conjunction with a 4-piston radial brake caliper, as this results in a very favorable surface ratio of master to slave piston.
2-piston brake caliper
But even with a conventional brake caliper with Ø30mm piston diameter, the braking force is significantly higher than, for example, with a standard brake pump as used by Piaggio/LML ex works on the Vespa PX Disc/My/2011/Star/Stella models.
Converting partial hydraulics to full hydraulics
The cable-operated partial hydraulic disc brake kits are particularly impressive. The partial hydraulic master cylinder used by Grimeca has a very defensive design with Ø13mm. Converting to the 8.1 master cylinder significantly improves the hydraulic transmission ratio and the brake becomes much more aggressive with reduced leverage.
