Abstract
A slip-controlled hydraulic brake system which comprises a master cylinder and an auxiliary-pressure supply system is equipped with a travel-responsive switch actuatable by a piston of the master cylinder. An auxiliary-pressure supply system is used for the purpose of pressure delivery during the stop control phase and to safeguard a reserve volume or reserve stroke in the pressure chambers of the master cylinder. To this end, the auxiliary-pressure supply system will be activated and, if need be, check valves will be changed over on attainment of a limit value by virtue of the travel-responsive switch.
