Abstract: A caster brake construction comprising a base, a fork rotatably mounted on the base and having downwardly extending legs, an axle extending between the legs, and a wheel rotatably mounted on the axle. A washer is non-rotatably mounted on the axle exteriorly of one of the legs. A pedal is mounted on the axle exteriorly of the washer and has circumferentially spaced arcuate cam ways. Each cam way is tapered inwardly toward the center thereof and a plurality of circumferentially spaced projections on the washer normally engaging the deepest portions of the cam ways such that when the pedal is rotated in either direction from said normal position, the cam ways force the projections axially inwardly thereby forcing the one leg against the wheel to lock the wheel against rotation, and when the pedal is returned to its original position, the braking force is relieved.
