A caliper brake for a wheel of a bicycle comprises a pair of pivot mounts, each of which is adapted to be mounted on a bicycle member laterally of a wheel rim, one on either side of the wheel. A brake arm is pivotally mounted in cantilevered relation on each pivot mount adjacent its lower end, is biassed away from the wheel rim, and has a brake shoe affixed to it intermediate of its ends. A pivot bolt is affixed to a member of the bicycle above the wheel, and a spring retainer is mounted in a fixed position on the pivot bolt. A cam member is pivotally mounted on the pivot bolt adjacent to the spring retainer. A brake lever cable is connected directly to the upper end of one brake arm, and a sheath of the brake lever cable terminates at an end in engagement with the cam member. One end of a cable is affixed to the upper end of the other brake arm and at its other end to the cam. Stop surfaces on the cam member and the spring retainer engage to stop the pivotal movement of the cam member under the bias of a spring and thereby limit the rotation of the cam member under the bias of the spring.
