1. A braking apparatus for a rotary device, the rotary device including a rotating member and a non-rotating member, said braking apparatus comprising:

  • a braking member movably mounted to the non-rotating member of the rotary device;

    compression means, mounted to the non-rotating member and coupled to said braking member, for exerting a first force on said braking member to cause said braking member to contact the rotating member of the rotary device; and

    fine movement means, mounted to the non-rotating member, for actuating in response to a signal applied thereto to exert a second force on said braking member, the second force of said fine movement means counteracting the first force of said compression means to cause said braking member to separate from the rotating member.
