Abstract
Official abstract text for this publication.
A friction brake device for a vehicle includes: a hydraulic brake unit including a piston member for pressing a friction member by advancement; an electric brake unit including a nut member being relatively movable in a piston movement direction with respect to the piston member by a motor and for pressing the piston member by advancement; a piston return mechanism including a biasing member for making biasing force, oriented in a retreat direction, elastically act on the piston member in accordance with a relative advancement amount of the piston member with respect to the nut member; and a controller for controlling the motor. The controller determines whether an adjustment permission condition associated with a wear amount of the friction member is satisfied. When the condition is satisfied, the controller allows the motor to perform a relative position adjustment of the nut member with respect to the piston member.
