A device for regulating flex brake pedal feeling is disclosed. According to an embodiment of the present invention, the device for regulating flex brake pedal feeling, which is used to regulate a stroke length of a reaction piston in a petal simulator providing pedal feeling for a driver, comprises a petal simulator comprising a simulator block with an upper oil hole connected to a master cylinder to supply oil hydraulic pressure in response to pedal effort of the drive and an inner bore to communicate with the oil hole, first and second reaction force parts provided in series with the bore and pressured sequentially by oil from the oil hole, and respectively having a reaction spring compressed by pressure of the reaction piston and a damping member to supply reaction force, a fixed damping housing to support the second reaction force part and seal a lower end of the bore; and an actuator comprising a nut member provided in the damping housing not to rotate and supporting the damping member of the second reaction force part, a spindle member screw-connected to the nut member through a lower end of the damping housing and a motor connected to the spindle member to provide rotational force, wherein the nut member is linearly moved in response to normal and opposite rotations of the spindle member and stroke lengths of the reaction pistons of the first and second reaction force parts are varied as a position of the damping member installed in the second reaction force part is varied. |
