PURPOSE: A brake arrangement is provided to overcome or minimize the drawbacks associated with current brake arrangements. A particularly preferred objective is to provide a brake arrangement for an enclosed fluid immersed brake configuration. CONSTITUTION: An application discloses a brake assembly capable of providing a park/emergency brake facility and a service brake facility acting on the same friction pad or friction pad pair, the assembly including a rotatable disc rotor(23), at least one friction pad (27) adapted for movement towards a braking surface (25) of the disc rotor (23) to provide a braking effect, the assembly further including a first brake activating means (62, 63, 40) to provide the park/emergency brake facility operable selectively to urge the one friction pad (27) towards the braking surface (25) of the disc rotor (23), a second brake activating means (66, 32) to provide a service brake facility selectively operable independently of the first brake activating means to urge the one friction pad (27) towards the braking surface (25) of the disc rotor (23), and third means (71, 31) normally acting to prevent the first brake activating means (62, 63, 40) from urging the one friction pad (27) towards the braking surface (25) of the disc rotor (23).
