Abstract

The invention solves the problem of supplying fresh fluid, in particular in electrohydraulic brake systems, to all areas of the conduit systems that are not reached in a conventional brake fluid change.Therefore, the invention provides that a change of the pressure fluid be assisted by a hydraulic pump, during which change among others pressure fluid is delivered by means of the pump out of the pressure fluid reservoir through the inlet valves and out of the system through opened wheel bleeder connections.
