Abstract
An elevator brake includes a fluid enclosure that provides a force to counter a braking force. In a particular embodiment, the fluid enclosure functions as a fluid pressure amplifier between a controllable actuator and a braking surface. The fluid enclosure increases the force of the actuator such that smaller, more controllable actuators may be used to control the brake.
