A hydraulic brake system with slip control wherein at least one wheel brake (11) of an automotive vehicle is connected to a master cylinder (1). A normally opened inlet valve (8) which is adapted to be switched into a closed position is inserted in the connection between the master cylinder (1) and the wheel brake (11). The supply reservoir (6) of the master cylinder (1) contains an opening (13) which can be tightly closed by a filling device. To speed up the filling procedure of like brake systems, an additional connection is established between the supply reservoir (6) and the wheel brake (11) which is controllable by a valve (15). A like arrangement accelerates the venting and filling procedure, since the inlet valve (8) and its throttling action are by-passed.
A hydraulic brake system with slip control, wherein at least one wheel brake of an automotive vehicle is connected to a master cylinder, wherein a normally opened inlet valve is inserted in the connection between the master cylinder and the wheel brake, said inlet valve adapted to be switched into a closed position, and wherein the supply reservoir of the master cylinder includes an opening tightly closed by a filling device, wherein a connection is established between the supply reservoir (6) and the wheel brake (11) which is controlled by a first directional control valve (15), said first valve (15) having a control input responsive to hydraulic pressure in said supply reservoir (6) to switch said first valve (15) between open and closed positions and being arranged in said brake system to by-pass said inlet valve.
