A brake system comprising: a rotor comprising a rotor drive lug having a first axial side , a second axial side , and radially outward surface , wherein an axially extending groove is defined in the radially outward surface; a clip disposed in a circumferential gap between the rotor drive lug and an adjacent rotor drive lug ; a clip retainer for radially retaining the clip in the circumferential gap, the clip retainer comprising: a first segment comprising a first middle portion and first circumferentially lateral portions ; a second segment extending substantially parallel to the first segment and comprising a second middle portion and second circumferentially lateral portions ; and wherein the first middle portion and the second middle portion have a middle radial dimension that is comparatively less than a lateral radial dimension of the first circumferentially lateral portions and the second circumferentially lateral portions ; characterized in that a bridge segment extends substantially perpendicularly between the first middle portion of the first segment and the second middle portion of the second segment, and in that a radially outward surface of the bridge segment is substantially flush with the radially outward surface of the rotor drive lug. a rotor comprising a rotor drive lug having a first axial side , a second axial side , and radially outward surface , wherein an axially extending groove is defined in the radially outward surface; a clip disposed in a circumferential gap between the rotor drive lug and an adjacent rotor drive lug ; a clip retainer for radially retaining the clip in the circumferential gap, the clip retainer comprising: a first segment comprising a first middle portion and first circumferentially lateral portions ; a second segment extending substantially parallel to the first segment and comprising a second middle portion and second circumferentially lateral portions ; and wherein the first middle portion and the second middle portion have a middle radial dimension that is comparatively less than a lateral radial dimension of the first circumferentially lateral portions and the second circumferentially lateral portions ; characterized in that a bridge segment extends substantially perpendicularly between the first middle portion of the first segment and the second middle portion of the second segment, and in that a radially outward surface of the bridge segment is substantially flush with the radially outward surface of the rotor drive lug. a first segment comprising a first middle portion and first circumferentially lateral portions ; a second segment extending substantially parallel to the first segment and comprising a second middle portion and second circumferentially lateral portions ; and wherein the first middle portion and the second middle portion have a middle radial dimension that is comparatively less than a lateral radial dimension of the first circumferentially lateral portions and the second circumferentially lateral portions ; characterized in that a bridge segment extends substantially perpendicularly between the first middle portion of the first segment and the second middle portion of the second segment, and in that a radially outward surface of the bridge segment is substantially flush with the radially outward surface of the rotor drive lug. <EOS>
