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.
Claims19
A brake disk, comprising:
- a disk body having oppositely directed surfaces;
- at least one of the surfaces having a plurality of spaced, raised island formations and channels extending between the island formations;
- and each raised island formation having an outer friction surface which contacts a brake pad during braking;
- wherein at least the raised island formations have a surface texture having a predetermined three dimensional pattern;
- wherein the three dimensional pattern extends over the entire area of each surface;
- and
- wherein at least the friction surfaces of the island formations are coated with a coating comprising at least one layer of a coating material, the coating comprises a first layer of a first coating material and at least a second layer of a second coating material, the first coating layer comprises a metal, and wherein the first coating layer has a crystalline structure.
