The invention relates to a brake and to a method for controlling the brake. The brake comprises a base part (1), a braking piece (2) movably supported on the base part, which braking piece is configured to be moved between a braking position and a releasing position, a spring (5), with the spring force of which the braking piece (2) can be dropped into a braking position, a support member (3) for limiting the initial position of the drop-out movement of the braking piece (2) and also a controllable actuator (11), which is mechanically connected to the aforementioned support member (3) and configured to displace the initial position of the drop-out movement of the braking piece with respect to the braking position. |
