Abstract
The vehicle brake system includes a cylinder, an output piston disposed in the cylinder, an input piston disposed in the cylinder but separating from the output piston and defining a separation chamber therebetween, a brake pedal connected to the input piston, a reaction force generating device for generating an elastic reaction force, a separation lock valve for controlling the communication between the separation chamber and the reaction force generating device, a fade state judging portion to judge whether the friction brake device is in a fade state or not and a friction braking force control portion for changing the mode to the fade state when the fade state judging portion judged that the friction brake device is in the fade state, wherein a desired friction braking force can be assured even under the brake fade state.
