PROBLEM TO BE SOLVED: To provide brake equipment for improving safety of the brake equipment. SOLUTION: This brake equipment, particularly for a lift installation, comprises a static element (1), a movable element 2 which is movable relative to the static element in a first degree of freedom (ψand x), wherein selectably a first frictional contact can be produced in a first contact surface (6.1) between the static element (1) and the movable element (2) by a controllable normal force (FN) acting in a second degree of freedom (y), in which a first friction force (FR1) opposes movement of the movable element relative to the static element (1); at least one relative element (3), wherein a second frictional contact is produced in a second contact surface (6.2) between the movable element (2) and the at least one relative element (4) by the normal force (FN), in which a second frictional force (FR2) opposes movement of the movable element relative to the relative element.
