A brake device for a vehicle, comprising:
- a master cylinder generating hydraulic pressure;
- a pedal pressurizing the master cylinder;
- a pair of diverging line parts connected to the master cylinder so as to supply hydraulic pressure;
- a front wheel line part connected to each of the diverging line parts so as to guide hydraulic pressure;
- a combined brake connected to the front wheel line part, and generating hydraulic pressure while braking a front wheel according to an electrical signal;
- a rear wheel line part connected to the front wheel line part so as to guide hydraulic pressure;
- and
- a hydraulic brake connected to the rear wheel line part, and braking a rear wheel using hydraulic pressure.
A brake method for a vehicle, comprising:
- detecting whether a combined brake is normally operated, the combined brake serving to brake a front wheel through an electrical signal and hydraulic pressure;
- when the combined brake is normally operated, braking the front wheel through the combined brake receiving an electrical signal, and braking a rear wheel through a hydraulic brake using hydraulic pressure generated from the combined brake;
- detecting whether the front wheel and the rear wheel are in an ABS braking situation;
- and
- when the front wheel and the rear wheel are in the ABS braking situation, braking the front wheel through the combined brake receiving an electrical signal, and braking the rear wheel through the hydraulic brake using hydraulic pressure adjusted by a motor pump.
