Abstract
A wheel braking apparatus includes components that inhibit the rotation of a wheel when a ball bearing is placed in a braking position between a bearing wall of a non-rotating component and a bearing barrier of a hub interface component that is at least resistively connected to a hub of the wheel. In response to a wireless signal, the ball bearing is moved from a non-braking position and allowed to travel to a braking position between a bearing barrier of one side of a bearing groove and the bearing wall of the non-rotating component.
