ABSTRACT:
An antilocking brake fluid pressure control unit for a vehicle includes a fluid pressure control device which receives an antilocking operation signal for controlling the pressure applied to a wheel brake. A pump in a parallel flow circuit returns a brake working fluid. A damping chamber (13) is connected to a fluid passage (9) between an outlet port of the pump and a feedback point (15). A filter is provided in the fluid passage (9) between the damping chamber (13) and the feedback point (15). Due to this structure, air bleeding from a brake piping system is simplified when assembling the brake system in a vehicle, and the time needed for charging a working fluid into the brake system is reduced.
