Abstract
The disclosure relates to a brake actuating mechanism in which a brake applying member is urged to apply a brake by a heavy coil spring. To release the brake a pivoted lever acts on the brake applying member and is moved in a brake releasing direction by an electric motor driven lead screw on which there is a ball-screw nut acting on the lever. The ball-screw nut causes the lead screw to spin under the load imposed by the spring through the lever so that when the motor is unlocked, the spring can apply the brake.
