Electromechanical brake system and method

An electromechanical brake system capable of conducting a brake pad wear check includes a structure defining a chamber, a member that rotates with a wheel, a motor mounted to the structure, a reciprocating piston, a brake pad, and a controller. The piston is driven by the motor between a variable actuated position and a retracted position. The brake pad is movably supported by the structure, operatively coupled to the piston, and adapted for braking contact with the member when the piston is in the actuated position, and spaced from the member when the piston is in the retracted position. Thecontroller controls reciprocation of the piston between the actuated and retracted positions via energization of the motor, performs a brake pad wear check by calculating a change in a parameter associated with a change in distance between positions, and compares the change in parameter to a threshold value. 种能够实施制动器片磨损检查的机电制动器系统，其包括限定腔室的结构、随着车轮旋转的构件、安装于结构的电动机、往复活塞、制动器片以及控制器。活塞由电动机在可变致动位置和缩回位置之间驱动。该制动器片由结构可动地支撑，该结构操作地联接于活
