BRAKE DISC INSERT WITH RETAINER

IA drive insert for a brake disc comprises a clip (390) and a retainer (382). The clip is configured to be slidable over a surface adjacent to a drive slot of a brake disc in a tangential direction of the brake disc (336). The retainer is configured to be slidable over the clip when the clip is positioned over the surface to secure the clip to the brake disc. The clip comprises a body section (391) and first and second arms (396, 395) extending from the body section. The retainer comprises first and second legs (311, 313) configured to contact the first arm and the second arm of the clip when the retainer is positioned over the clip. The first and second legs are resiliently biased to provide an inward clamping force on the clip when the retainer is positioned over the clip.
