Abstract: The braking device for a vehicle includes a judging portion which judges whether the input piston and the output piston are in contact with or separated from each other and a control portion which outputs the control signal to the pilot pressure generating device so that the hydraulic pressure detected by the hydraulic pressure detecting device becomes a target value corresponding to a vehicle state, when judged that the input piston is not in contact with the output piston and outputs another control signal to the pilot pressure generating device, by which the pilot pressure becomes higher than the pilot pressure generated under a same vehicle state to a vehicle state in a case that the control signal is outputted when the judging portion judges that the input piston is not in contact with the output piston, when judged that the input piston is in contact with the output piston.

Abstract: A vehicle hydraulic brake system of the brake-by-wire type includes input piston and a master piston configured to be actuated under hydraulic pressure introduced into a second fluid chamber and mounted in the housing so as to be movable relative to each other through a partition wall and a first fluid chamber. The piston defines therein a communication passage which extends from a fourth fluid chamber to the first fluid chamber and in which a check valve is mounted. When the piston is advanced under hydraulic pressure introduced into the second fluid chamber, the volume of the fourth fluid chamber decreases, while the volume of the first fluid chamber increases. This allows brake fluid in the fourth fluid chamber to be quickly released into the first fluid chamber through the communication passage and through a pipe line in which an electromagnetic on-off valve are mounted.
