1. A caster wheel brake system comprising:
a caster wheel assembly configured for mounting to a mobile support, said caster wheel assembly comprising a wheel;
first and second handles configured to be coupled to the mobile support in a spaced arrangement and each movable from a respective locking position to a respective unlocking position;
a rotator link coupled to said first and second handles and configured to rotate when either of said first and second handles is moved between its respective locking and unlocking positions, wherein said rotator link comprises first and second fork linkages coupled to said first and second handles, respectively;
a brake-actuating link coupling said rotator link to a brake associated with said wheel;
a slotted link defining a slot, said slotted link slidably coupling said second handle to said rotator link;
wherein moving said first handle to its unlocking position urges a portion of said rotator link to slide within said slot;
wherein movement of either of said first and second handles from its respective locking position to its respective unlocking position rotates said rotator link and said brake-actuating link in a disengagement direction; and
wherein rotation of said brake-actuating link in the disengagement direction urges the brake out of a braking position that limits or prevents rotation of said wheel, to a released position that permits rotation of said wheel.
