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 fir st degree of freedom (.phi.; 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) a nd the at least one relative element (4) by the normal force (FN), in which a second friction force (FR2) opposes movement of the movable element relative to the relative element. The at least one relative element (3) is movable in the first degree of freedom (.phi.; x) relative to the static element between a normal position (A) and a braking position (B), wherein the relative element (3) is resiliently biased into the normal position (A).</SD OAB>
