A hydraulic system servicing apparatus (10) includes an old fluid holding vessel (114) and a new fluid supply vessel (100) with a selector valve (92) which draws fluid from the holding vessel during flushing operations and dra ws fluid from the supply vessel during fluid replacement and bleeding operation s. A pump (102) moves the fluid through the selector valve (92) and supplies it to a flow reversing valve (66) which has a master cylinder line (76) and a plurality of bleeder valve lines (40,42,44,46) for connection to the hydraul ic system. A shutoff valve (48,50,52,54,56) is provided in each bleeder valve line for directing fluid through the different branches of the hydraulic system. To flush the system, the flow reversing valve (66) is cycled to circulate the fluid from the old fluid holding vessel (114) in opposite directions and return it to the old fluid holding vessel. To replace the flu id and bleed the system, the fluid selector valve directs new fluid through the flow reversing valve into the system. |
