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: An electrically actuated brake assembly includes a brake disc, a brake pad, and an electric motor having a rotatable output shaft. A service brake transmission in operative rotational communication with the output shaft causes service braking of the vehicle in response to rotation of the output shaft, and an adjuster mechanism is operable to adjust a distance between the brake pad and the brake disc. An adjuster transmission operatively connected between the output shaft and the adjuster mechanism causes operative rotational communication between the output shaft and the adjuster mechanism when the adjuster transmission is engaged so as to transmit rotational movement of the output shaft to the adjuster mechanism, and causes there to be no operative rotational communication between the output shaft and the adjuster mechanism when the adjuster transmission is disengaged so as to not transmit rotational movement of the output shaft to the adjuster mechanism.
