Abstract: A method for controlling the braking action applicable by a brake caliper on a mechanical movement member of a vehicle is described. An electronic control unit operatively connected to an actuator assembly receives an input signal representative of a braking request. The unit determines a first reference value of a position of a component in the actuator assembly and a second reference value of a parameter representative of the braking action applicable by a brake caliper via the actuator assembly. The unit determines at least one feedback value of the position of a component in the actuator assembly. The unit also generates at least one control signal for the actuator assembly based on feedback values and the reference values.
