A method for haptic information of a driver of a "brake-by-wire" -Bremsanlage equipped motor vehicle via an operating state of the brake system, the brake system a means of a brake pedal (1) actuated master brake cylinder (2) with at least one pressure chamber (17, 18) which is provided with at least one wheel brake (8, 9; 10, 11) is connected or connectable, and with the master brake cylinder (2) cooperating simulation means (3), which the driver in a 'brake-by-wire "mode, a brake pedal feel conveyed, said associated in the presence of a predetermined operating state, in particular in the 'brake-by-wire "mode, by means of the pressure chamber (17) of the master brake cylinder (2) release valve (32, 32') by means of which the effect of the simulation device (3) is switched on and switched off, a brake pedal return action, in particular a change in the perceived by the driver rigidity of the brake pedal (1), by is performed, as well as brake system.
