The brake system includes a sun gear fixedly mounted to an input shaft. The sun gear is mounted inside a planetary chassis between two pinion gears. The sun gear has teeth protruding from its circumference on both sides thereof. The teeth are aligned in such a way that when the sun gear is turned to a neutral position, the teeth are engaged with the pinion gears, preventing a rotation of the pinion gears, and when the sun gear is rotated away from the neutral position, the teeth are disengaged from the pinion gears allowing the pinion gears to rotate. When no torque is applied to the input shaft, the sun gear is urged back to its neutral position. In a second embodiment, the sun gear is urged in a drag mode against the trailing side of the teeth on the pinion gears, for producing a pawl-and-latch noise during use.
