Abstract
A hydraulic brake system includes a master cylinder, a wheel brake, an electronic valve provided to each of an inlet and an outlet of each of wheel brakes, a pump compressing oil stored in a low pressure accumulator such that oil is ejected towards the wheel brake or master cylinder, an orifice disposed near an outlet port of the pump, a first hydraulic circuit connecting a first port of the master cylinder to two wheel brakes to control transmission of hydraulic pressure, and a second hydraulic circuit connecting a second port of the master cylinder to the remaining two wheel brakes to control transmission of hydraulic pressure, wherein a damper unit is disposed between the outlet port of the pump and the orifice to relieve a pulsation phenomenon. The damper unit allows main flow passages of the first and second hydraulic circuits to communicate with each other therethrough.
