Abstract
The invention provides a wheel assembly consisting of first and second spaced apart coaxial wheels. The wheel are mounted on a support structure such that they can rotate relative to one another. A first brake rotor is non-rotatably connected to the first wheel, and a second brake rotor is non-rotatably connected to the second wheel. A brake stator is operable on each rotor to oppose rotation of the two brake rotors simultaneously.
