ABSTRACT:
A friction disk assembly comprises an annular structural carrier including a plurality of recessed regions and torque drive notches spaced around its circumferential direction, and a friction lining mounted on the carrier, the friction lining having a flat wear (rubbing) face and an obverse face including raised areas corresponding to and matingly engaging the recessed regions of the carrier to prevent rotation of the lining relative to the carrier. The carrier may be formed of steel or other suitable structural material. The lining may be formed of virgin or recycled carbon, ceramic or other suitable friction material. The lining may be retained to the carrier by rivets. The lining may be provided with a structural casing configured to engage the recessed regions of the carrier. The assembly may be refurbished by simple replacement of the worn lining. The carrier and the lining may be formed as unitary annular members or as segments of annular members.
