Brake disc system

A brake disc, comprising:

• a lining carrier defining an inner perimeter defining a disc aperture and an outer perimeter surrounding the inner perimeter,
• wherein the lining carrier is configured to rotate around a disc axis extending through the aperture,
• wherein the lining carrier defines a carrier surface between the inner perimeter and the outer perimeter and a protrusion extending from the carrier surface,
• wherein the carrier surface and the protrusion are configured to rotate around the disc axis when the lining carrier rotates about the disc axis, and
• wherein the lining carrier defines a disc slot on one of the inner perimeter or the outer perimeter, the disc slot configured to receive a torque around the disc axis from a rotor drive key or a spline extending through the disc slot;
• a friction pad configured to cover at least a carrier surface, wherein the friction pad defines a recess boundary defining a recess;
• and
• a fastener configured to extend through at least a portion of the friction pad to couple the friction pad to the lining carrier,
• wherein the friction pad is configured to rotate around the disc axis when the lining carrier rotates about the disc axis and the friction pad is coupled to the lining carrier,
• wherein the protrusion is configured to insert within the recess when the friction pad is coupled to the lining carrier, and
• wherein the recess boundary is configured to transfer a torque around the disc axis from the friction pad to the protrusion when the protrusion is inserted in the recess and the and the torque is imparted to the friction pad.

A method, comprising:

• covering, using a friction pad defining a recess boundary defining a recess, at least a portion of a carrier surface of a lining carrier of a brake disc, wherein a protrusion extends from the carrier surface, wherein the friction pad is configured to rotate around a disc axis when the friction pad covers the carrier surface and the lining carrier rotates about the disc axis, and wherein the protrusion inserts within the recess when the friction pad cover the carrier surface;
• transferring a torque on the friction pad, using the recess boundary, to the protrusion;
• and
• transferring the torque, using the protrusion, to a body of the lining carrier.
