In some examples, a disc brake assembly and methods of forming and assembling said brake disc assembly. The brake disc assembly including a core structure and a plurality of wear pads. The core structure having a first major surface comprising at least one curved ridge or curved channel that extends in a radial direction along the first major surface between an inner and outer diameter of the core structure. Each wear pad defining a friction surface and a mounting surface such that the mounting surfaces of the plurality of wear pads are positioned adjacent to, and in contact with, the first major surface of the core structure, where at least one of the mounting surfaces of the plurality of wear pads includes a corresponding curved ridge or curved channel configured to interlink with the at least one curved ridge or curved channel of the core structure.
