An electronically controllable pneumatic brake system has a primary service brake pressure modulator, a primary control unit, a secondary control unit that controls the first service brake circuit in the event of a fault, and a secondary service brake pressure modulator connected to the secondary control unit. The secondary service brake pressure modulator is supplied with reservoir pressure and has a secondary working connection for providing a redundancy brake pressure. A parking brake assembly is supplied with reservoir pressure and provides at a parking brake working connection a parking brake pressure for spring brake cylinders. A ventilation valve unit is arranged downstream of the secondary working connection and is connected to the secondary control unit and ventilates the secondary working connection in accordance with a ventilation signal provided by the secondary control unit so as to lower a reservoir pressure in order thereupon to ventilate the spring brake cylinder.
