| 摘要 |
The present invention relates to an electronic hydraulic brake system comprising: a main master cylinder supplying hydraulic pressure to a wheel cylinder operated by a motor in response to a control of an electric control unit; and a backup master cylinder forming a reaction force in a pedal in response to the pressure of the brake pedal. The hydraulic pressure is capable of being transmitted to the main master cylinder although a power source is not applied to the electric control unit in order to enable manual bleeding when the power source is cut for an after service of a vehicle and reducing the number and a size of components to reduce weight of the vehicle and manufacturing cost. |
