A caster assembly having rattle-free operation is presented. The caster comprises an inverted U-shaped horn member carrying an axle (i.e., a shoulder bolt). A wheel rotating on a spanner is supported between leg portions of the horn by the axle. A brake support and treadle lever are mounted on the axle and provide for locking the caster wheel. A spring tab is formed integrally in the treadle lever. The spring tab is spring biased inwardly to force the brake support and the treadle lever apart. The maintenance of a constant tension separating the brake support and the treadle lever results in rattlefree operation of the caster assembly of the present invention.
