A hydraulic brake system for a land vehicle, having a master cylinder, which is actuable by the driver by means of a pedal directly or via a brake booster disposed downstream of the pedal, for generating brake pressure in two brake circuits, each of which comprises two wheel brakes, wherein a hydraulic connection between the master cylinder and the wheel brakes is to be established or blocked by valve arrangements in dependence upon trigger signals from an electronic control unit in order to implement normal braking operations brought about directly by the driver or braking operations influenced by the electronic control unit in dependence upon measured variables, which are supplied to the electronic control unit and reflect the vehicle behaviour and/or the driver request, in that the brake pressure characteristic in the wheel brakes is varied by activating the valve arrangements associated therewith, wherein the electronic control unit is devised and programmed in such a way that, in order to set a brake pressure characteristic required for a specific vehicle behaviour, it supplies trigger signals, by means of which the setting of a respective brake pressure characteristic in the two brake circuits in predefined pressure stages (delta-p) is staggered in terms of time by a substantially predefined time stage (delta-t).
