A ski brake consisting of spring wire having attached thereto brake arms which are movable between a position spaced above the upper surface of a ski in a retracted position thereof and a position spaced alongside the lateral edges of the ski and projecting beneath the bottom surface of the ski into a braking position. The part of the ski brake which is above the upper surface of the ski has a pedal associated therewith upon which a skier can step to facilitate a movement of the ski brake to the retracted position. The pedal has a fingerlike projection thereon on which is provided a wedge which cooperates with the spring wire to facilitate a spreading of a portion thereof to effect a drawing in of the brake arms over the upper surface of the ski as the ski brake is pivoted to the retracted position. The fingerlike projection is pivotally secured to a part movable with the pedal and, when the skier steps on the pedal, the fingerlike projection will be pivoted as the pedal moves toward the upper surface of the ski to drive a wedge on the projection between a pair of spaced parts on the spring wire to cause a spreading of the spring wire in the region of the spring wire adjacent the pedal. This movement effects a drawing in of the brake arms which are at the end of the spring wire remote from the pedal.
