A rail vehicle brake unit (200) contains a brake actuator (120), at least one pressing member (211), a gear assembly (220), an electric motor (230) and a backup power unit (123). The brake actuator (120) receives a brake command (cmdB) and produces an electric brake-force signal (BF) to the electric motor (230) that, in turn, acts on the gear assembly (220) to cause the at least one pressing member (211) to attain a specified position in relation to a rotatable member (110) mechanically linked to at least one wheel (105) of a rail vehicle so as to apply a braking force thereto. During operation of the rail vehicle, the backup power unit (123) receives electric power (W) from a power line (140) in the rail vehicle and accumulates the received electric power (W). In case of an electric power failure (PF) in the electric power (W) received in the brake actuator (120), the backup power unit (123) provides the accumulated electric power to control circuitry in the brake actuator (120) and the electric motor (230).
