12. A brake system for a motor vehicle comprising:
a mechanically actuable master brake cylinder a first partial reservoir of a brake fluid vessel fluidly connected to the master brake cylinder;
a second partial reservoir of the brake fluid vessel;
an electric linear actuator connected to the first and second partial reservoirs of the brake fluid vessel, wherein the master brake cylinder and the linear actuator are connected via an electrically closable circuit isolating valve; and
a control unit of the brake system with instructions for:
transitioning the brake system to a standby state;
detecting if a leak is present at one of the wheel brakes during the transition; and
displacing a brake fluid volume from the first partial reservoir via the circuit isolating valve which is open into the second partial reservoir by activating the electric linear actuator.
