1. A brake assembly comprising:
a rotor defining an aperture, an axis of rotation of the brake assembly extends through a center of the aperture; and
a spindle within the aperture, the spindle in cooperation with the rotor to restrict independent rotation of the rotor and the spindle about the axis of rotation, restrict axial movement of the rotor relative to the spindle along the axis of rotation, and accommodate radial expansion of the rotor in a plane perpendicular to the axis of rotation,
wherein:
the rotor includes alternating rotor recesses and rotor ridges defining the aperture;
the spindle includes alternating spindle recesses and spindle ridges around an outer periphery of the spindle; and
each one of the spindle recesses cooperates with one of the rotor ridges and each one of the spindle ridges cooperates with one of the rotor recesses so that the rotor rotates with the spindle.
