Abstract
A brake disk or drum has at least one working surface which opposes a braking member such as a brake pad or shoe. A plurality of spaced, raised island formations are provided across the working surface, with channels extending between the island formations. Each raised island formation has an outer surface which contacts a brake pad or brake shoe during braking.

A method of forming a braking surface on a substrate material, comprising:
- machining the braking surface on the substrate material to form a plurality of spaced, raised island formations with channels extending between the island formations;
- finishing outer surfaces of the plurality of spaced, raised island formations to form a friction surface, the friction surface configured to engage a brake pad;
- and
- applying a wear and corrosion resistant coating to the friction surface, the wear and corrosion resistant coating comprising:
- a first coating layer of a first coating material, the first coating material comprising a crystalline material;
- and
- a second coating layer of a second coating material;
- wherein the wear and corrosion resistant coating is configured to reduce, during use of the braking surface in braking of a vehicle, wear of the plurality of spaced, raised island formations relative to the substrate material in an uncoated state.
