Method for operating an electrically actuated handbrake

The method involves axially displacing a control piston over radial gaskets in valve housing. A control input (50) is ventilated in a switching state of a control valve device (22). The control input is deaerated in another switching state of the control valve device. An exhaust port (70) is ventilated by a controlling and exhaust valve device (72) while the control input is deaerated.
