Abstract
A multi-stage wet disc brake assembly has a first actuator is supported within a housing and moveable toward point of friction discs. A second actuator coacts with the first actuator and is moveable relative to the first actuator toward the friction discs. One of the actuators reduces the running clearance between the friction discs and the other of the actuators forces the friction discs together to slow rotation of a rotatable member relative to the housing when the rotatable member is being driven.
