An electro-hydraulic brake (EHB) system of a vehicle, the vehicle is equipped with brake pedal, brake pushrod, wheel cylinders, brake pedal sensors, on-board vehicle sensors. The EHB system includes a manual boost cylinder, an electric power assist assembly and a master cylinder. The manual boost cylinder includes a sliding cylinder body, a large piston and a small piston. The manual boost cylinder also include interlocking means that selectively operate on locking or unlocking between the sliding cylinder body, the small piston and the large piston based on a plurality of positions of the small piston within the manual boost cylinder body. The electric power assembly includes an electric motor, a pinion gear and a rack and a master cylinder. The master cylinder includes a first piston, a second piston and limiter means.
