Abstract: A brake rotor includes a first disc member having a first body provided with a first braking surface, a first inner surface and a first annular rim. The first annular rim includes a first groove and one or more connection elements. A second disc member includes a second body having a second braking surface, a second inner surface and a second annular rim. The second annular rim includes a second groove and one or more connection members. The connection members are configured and disposed to register with corresponding ones of the connection elements such that the first groove aligns with the second groove. A linking member extends within the first and second grooves to detachably join the first and second disc members.

Abstract: The disclosed apparatus relates to a liquid cooled brake apparatus comprising: a housing, a brake cooling pump mounted to said housing, a braking force actuator mounted to said housing, said actuator being driven by a first driven member; and a braking force applicator in operable communication with said braking force actuator and a brake rotor, the rotor rotationally fixed to said first or a second driven member. The disclosed method relates to a method of retarding a driven member comprising: driving a braking force actuator with a first driven member, actuating a braking force applicator; and retarding the rotation of a rotor rotationally fixed to said first or a second driven member.
