A friction disk of a braking system may include a friction disk core and a first wear liner. The friction disk core has an outer surface that defines a recess extending gradually inward from the outer surface, according to various embodiments. The wear liner mates to the outer surface of the friction disk core and includes a wear surface and a first non-wear surface, according to various embodiments. The first wear liner further includes a notch extending gradually outward from the first non-wear surface of the wear liner, according to various embodiments. In an installed state, the notch is received within the recess, according to various embodiments.

An article includes a structural core, one or more friction pads, and a plurality of elongated fasteners. The structural core includes two core surfaces and a plurality of pockets extending between the core surfaces. Each friction pad includes a pad surface and a friction surface opposite the pad surface. Each pad surface includes a planar pad surface configured to contact the core surface and a plurality of bosses extending from the first planar pad surface and including a bore. Each planar pad surface is at least about 50% of a surface area of the respective first and second pad surfaces. The plurality of bosses engages with the plurality of pockets to position the respective first and second friction pads relative to the structural core. The plurality of elongated fasteners passes through bores of corresponding bosses of friction pads to fasten the friction pads to the structural core.
