    • Brake disc drive inserts (20) for use in carbon-carbon composite brake discs. A rotatable brake disc annular drive insert (20) includes a cylindrical steel body (22) having one side of the body truncated to provide an insert opening (21) which extends axially through the body. The insert opening (21) extends into the body along diameter of the body and the insert opening terminates at a radially extending surface located between the revolutional center of the body and an outer surface of the body. End flanges (26) extend radially outwardly from the outer surface of the body (22) to provide for axial positioning of the drive insert relative to a brake disc. The insert opening has a lining (15) comprising carbon-carbon composite material. This low friction carbon-carbon composite material bed that is positioned between the steel insert component and the torque tube spline location provides significantly lower friction and enables significantly greater disc clamping and brake torque.
