Braking system for vehicles, in particular for cycles and motorcycles, and actuation method for a braking system
A braking system for vehicles may have a pilot pump fluidically connected to a hydraulic actuator device. The hydraulic actuator device has a by-pass, configured to connect or disconnect fluidically a first actuation chamber and a delivery duct, where a movable septum is connected to a motor device. The movable septum places the first actuation chamber in communication with the by-pass and with a second actuation chamber, to a braking correction condition. The motor device is activated to translate the movable septum so that the first actuation chamber is fluidically separated from the by-pass and from the second actuation chamber. The second actuation chamber, fluidically connected to the delivery duct, controls the actuation of the braking device, excluding the action imposed by the user through the fluid under pressure in the first actuation chamber.
