A ski brake has a base plate and has a stepping plate which is hinged to the base plate by means of a transverse axle and is biased by an erecting spring, in which stepping plate or on which stepping plate are pivotally supported two braking mandrels by their support sections. Pivotal movement of each braking mandrel occurs either by means of a coarse thread provided on its support section which operatively engages an internal thread of a structural part fixed on the stepping plate or movable relative to the stepping plate, or by means of a helical slot which guides the transversely extending section of the braking mandrel. |
