Actuator device (4) for a combined rear-front brake system of a motor vehicle (8) comprising a device body (12) which houses and guides an actuating rod (16), for the mechanical actuation of an associable first braking device (20), wherein the device body (12) defines an axial direction (X-X), a manually actuated lever or pedal (24) mechanically connected to said device body (12) in order to control the translation thereof along said axial direction (X-X), by a first actuation stroke (26) according to a first actuation direction (A), wherein the device body (12) defines a hydraulic fluid chamber (28) which houses a float (32) adapted to pressurise said hydraulic fluid chamber (28), the chamber (28) being able to be fluid-connected through a delivery (36) to an associable second hydraulically actuated braking device (40), separate from the first braking device (20). Between the float (32) and the device body (12) there are arranged elastic means (44) so as actuate the float (32) and pressurise the hydraulic fluid chamber (28), as a result of the actuation of the actuating rod (16) by the manually actuated lever or pedal (24). |
