a braking circuit provided with an antilocking apparatus , which prevents the pumping pulsation from transferring onto the master cylinder side during pumping operation time in a reflux system of antilocking apparatus of discharging the operating liquid into the reflux passage from the wheel brake at the antilocking time so as to reflux it onto the master cylinder side by a pump provided on the reflux passage , thereby to effectively restrain the undesired pulsation to be transferred onto the master cylinder side by the equalization of the discharge pressure through the absorption of the discharge pressure .
