Abstract

A Coulomb friction damped disc brake rotor, wherein damping is provided Coulomb friction in generally coextensive relation with the braking surfaces of the one or more rotor cheeks. The Coulomb friction damped disc brake rotor has at least one interfacial boundary formed in at least one rotor cheek disposed in generally coextensive relation to the braking surface thereof. The interfacial boundary provides a mechanically distinguishable surface boundary between two surfaces which are in mutual contact such that a state of Coulomb friction exists therebetween.
