In a rail vehicle (100), a brake actuator (120) receives a brake command (BC) specifying a target force. In response to the brake command (BC), the brake actuator (120) controls an electrically operated brake unit (130) to perform a braking operation. The brake actuator (120) contains a control unit that generates a brake control signal (BS) based on the brake command (BC). The brake control signal (BS), in turn, controls an electric motor (131) in the electrically operated brake unit (130), such that an output shaft of the electric motor (131) attains a specified angular position in which at least one pressing member (135) is caused to apply a force against a rotating member (136) being mechanically connected to a wheel axle (141) of the rail vehicle (100), which applied force has the target force as a set point. The control unit also obtains a first sensor signal (Pm) reflecting a measured position of the output shaft of the electric motor (131), which measured position indicates the specified angular position, and thus informs the control unit when the at least one pressing member (135) applies the target force to the rotating member (136).
