Abstract (en)

[origin: WO2004016487A1] The invention is based on the problem in that, particularly in electrohydraulic brake systems, areas exist inside the line systems that are not reached during a conventional bleeding. This occurs, in particular, when the suction line is detached from the system pump during repair work carried out on the system. For this reason, the invention provides a pump-driven bleeding during which, among other things, pressure medium is, when outlet valves (9) are open, returned by the pump to the reservoir (4) from the pressure medium storage tank via the outlet valves (9). The pump (5) or the outlet valves can be controlled in a clocked manner in order to produce pressure pulsations that effect a removal of clinging air bubbles.
