The disclosure illustrates and describes a guide element which extends from a first end via a guide portion to a second end. The guide element has a fixing portion arranged at the second end and extending along a first extent direction, which runs transversely with respect to the axial direction, to a free end. The guide element has a connecting portion between the guide portion and the fixing portion. The connecting portion extends along a second extent direction, which runs transversely with respect to the axial direction and transversely with respect to the second extent direction, and extends along the axial direction from a first plane, which runs perpendicular to the axial direction, to a second plane, which runs perpendicular to the axial direction. The fixing portion is spaced apart in an axial direction both from the first plane and from the second plane. The disclosure furthermore relates to a corresponding brake anchor and to a corresponding disk brake system.

In some examples, a drive insert comprises a clip and a retainer. 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. 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. In some examples, the clip may comprise a body section and first and second arms extending from the body section. The retainer may comprise first and second legs 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 may be resiliently biased to provide an inward clamping force on the clip when the retainer is positioned over the clip.
