An installation structure of a pedal stroke sensor of an integrated dynamic brake (IDB) system is disclosed. The IDB system includes a hydraulic block, a hydraulic pressure generator, and an electronic control unit (ECU). The hydraulic block includes not only a master cylinder connected to a brake pedal but also a plurality of passages and valves needed to adjust a brake hydraulic pressure. The hydraulic pressure generator includes a motor that is connected to the hydraulic block and operates by an output signal of a detection sensor for sensing displacement of the brake pedal, thereby generating brake hydraulic pressure. The ECU controls the motor and the valves based on pressure information and pedal displacement information. The installation structure of the pedal stroke sensor includes a magnet installed in a piston that slidably moves within the master cylinder by interacting with the brake pedal. The detection sensor includes a first sensor and a second sensor that are spaced apart from each other by a predetermined distance in a movement direction of the piston in a manner that the first and second sensors detect a magnetic flux density of the magnet in response to movement of the piston.
