The invention relates to a brake device (1) for a lift installation (100) for generating a friction grip on a rail (101) of the lift installation (100), wherein the brake device comprises two legs (2, 3) with brake ends (4, 5). The first leg (2) is connected in an articulated manner to a first articulation point (11) of at least one transfer lever (12), which has, located at a distance in the longitudinal direction from the first articulation point (11), a second articulation point (13) which is connected in an articulated manner to a first pivot (14) of at least one pressure lever (15). The second leg (3) is connected in an articulated manner to a second pivot (16) of the pressure lever (15). A third pivot (17) of the pressure lever (15) is connected in an articulated manner to an articulation point (18) of an actuating element (19), particularly a crank articulation point of a crank rod, such that, as a result of a longitudinal movement (23) of the actuating element (19), the brake device (1) can be moved from a braking position, in which the brake ends (4, 5) are at a minimum distance (20) from one another, into an opened position, in which the brake ends (4, 5) are at a maximum distance (21) from one another, and vice versa. The longitudinal movement (23) of the actuating element (19) is predefined by a first end point (23a) and a second end point (23b).
