The fluid column separation occurring in the pressure control line of Anti-lock Braking System (ABS) of vehicles was analyzed experimentally. As the experimental setup, the ABS for passenger cars installed on the test stand was used. The pressure fluctuation was measured with a pressure sensor installed on the pressure control line. The tube of the connection part of the ABS hydraulic unit and the pressure control line was changed to a transparent pipe, and the vapor column was observed. The fluid column separation occurred when the pressure control valve in the hydraulic unit was operated to increase braking pressure. The mechanism of occurrence of fluid column separation in ABS braking piping system and the influences that the time of opening the pressure control valve and the length of pipng exerted to pressure fluctuation were analyzed in this paper.
