In one aspect, the invention relates to a hydraulic brake system for a motor vehicle, having a first hydraulic partial circuit, comprising a mechanically actuable master brake cylinder (2), which is connected to a first partial reservoir (10) of a brake fluid container (4), and at least two first wheel brakes (8a, 8b) with associated inlet valves (6a, 6b) and outlet valves (7a, 7b), and a second hydraulic partial circuit, comprising an electric pressure-providing device (5), which is connected to a second partial reservoir (11) of the brake fluid container (4), and at least two second wheel brakes (8c, 8d) with associated inlet valves (6c, 6d) and outlet valves (7c, 7d), wherein the first partial circuit and the second partial circuit are connected separably via an electrically switchable circuit separation valve (40). In order to improve the availability of the brake system, a control unit is configured to carry out leakage detection, when a leakage is detected to carry out leakage localization and, in the event of a leakage in the second partial circuit, to open or to keep open the circuit separation valve (40) and to close the inlet valves (6c, 6d) of the second wheel brakes (8c, 8d), and, in the event of actuation of the brake pedal (1), to activate the pressure-providing device (5) to build up a brake pressure in the first wheel brakes (8a, 8b). In a further aspect, the invention relates to a method for controlling a brake system in the event of leakages.
