Claims12
A control device for hydraulic brakes of a two-wheeled vehicle provided with a first brake for a first wheel and a second brake for a second wheel, the control device comprising:
- a first brake master cylinder comprising:
- a master cylinder body,
- a first hydraulic chamber formed in the master cylinder body and hydraulically connectable to the first brake, and
- a first piston, movable in the first hydraulic chamber;
- a manual control lever, rotatable with respect to the master cylinder body, acting on the first piston to operate the first brake;
- wherein the control device further comprises:
- a second brake master cylinder, comprising:
- a second hydraulic chamber formed in the master cylinder body and hydraulically connectable to the second brake, and
- a second piston, movable in the second hydraulic chamber for operating the second brake by said manual control lever,
- a switching member, associated with the manual control lever, to selectively activate and deactivate the second piston, the switching member having two alternative positions:
- a first passive position, in which a rotation of the manual control lever does not activate the second piston, and
- a second active position, in which a rotation of the manual control lever simultaneously actuates the first piston to actuate the first brake and the second piston to actuate the second brake, according to a combined or integral braking mode.
