A caster wheel assembly includes a vertical axis brake and barrier-traversing member. The caster shaft housing contains a stator surface adjacent the caster wheel assembly. The barrier-traversing member with barrier contact surface is biasedly fastened to the caster wheel assembly. A brake pad member is attached to the barrier-traversing member opposite the barrier contact surface and adjacent the stator surface. In operation, the moving caster wheel assembly first contacts an obstacle with the barrier contact surface of the barrier-traversing member. The encountered obstacle elevates the barrier-traversing member and attached brake pad member into contact with the stator surface of the caster shaft housing, thereby restraining rotation of the caster wheel assembly. Then, further forward movement of the rotation-restrained caster wheel assembly allows the barrier-traversing member to elevate the caster wheel, transfer load to the caster wheel, and thereby more easily traverse the obstacle.
