Abstract: A method for operating a brake system. A brake request signal characterizing a brake request is generated by actuating a positioner system of an actuating circuit, and a setpoint brake pressure required in an active circuit is ascertained based on the brake request signal. An actual brake pressure is set in the active circuit according to the setpoint brake pressure using a pressure generation device by moving a displacement piston using an electric motor to actuate a wheel brake coupled with the active circuit. Under the condition that the brake request signal is constant over a predefined period of time, a pressure modulation is carried out, which includes setting the actual brake pressure in the active circuit to a value that is greater than the setpoint brake pressure, and lowering the actual brake pressure by moving the displacement piston using the electric motor until the setpoint brake pressure is reached.
