The cyclic carbon brake disc overhaul technique comprises the steps of splitting a worn carbon disc (10, 100 ) into two equal disc halvess (16, 116), machining the disc halves (16, 116) to a predetermined axial thickness, and then bonding the disc halves (18, 118) of predetermined thickness to a core member (22, 122). The disc halves (18) may include drive regions (20) at respective ends thereof, or the halves (118) may have the drive regions (112) removed therefrom. The core member (224) may have axially extending drive portions (225) such that the disc halves (118) of reduced radial length define wear grooves (227) with the drive portions (225).
