The present disclosure relates to a brake device for an elevator system and a testing method thereof. The brake device of the present disclosure includes: a fixed member (1); a moving member (2) movable between a retracted position and a braking position so as to realize switching of the moving member (2) between an attracting state and a braking state, respectively; an elastic member (51; 52) to provide elastic force tending to push the moving member (2) toward the braking position; a coil (61; 62) configured to produce an electromagnetic force tending to drive the moving member (2) to move toward the retracted position when energized; and a controller configured to control a change of a magnitude of the electromagnetic force produced by the coil (61; 62) in a process of testing the spring force of the elastic member (51; 52), and to acquire corresponding information of the electrical signal for controlling the magnitude of the electromagnetic force when the moving member (2) switches from the attracting state to the braking state so as to evaluate the spring force being tested. The brake device and the testing method thereof of the present disclosure can automatically achieve the performance testing of the elastic member (51; 52), and do not realize relying on sensor as well as being low in cost.
