A perforating gun brake includes a first body having an axis. Several gripping feet are provided each having a pivot end and a remote end. The pivot end is pivotally mounted to the first body. The gripping feet are movable between a stored position substantially parallel to the axis of the first body and an engaging position extending outwardly at an angle in relation to the first body. A second body is coupled to and axially movable relative to the first body. A wedge member is carried by the second body. The wedge member exerts a force upon the remote end of the gripping feet upon movement of the second body to force the gripping feet outwardly into the engaging position.
