Abstract
A wheel brake for a bicycle or other vehicle has a pair of pivoting arms. Each arm is configured to support a brake pad. A first arm pivotally supports a cam. A second arm defines a cam surface and a cable guide. The cam has a first end for mounting of a cable and a second end having a roller which rests on the cam surface. When the cable is actuated, the cable pulls the first end of the cam, causing the cam to pivot and causing the second end of the cam to roll along the cam surface. Force applied by the cam compresses the arms, causing associated brake pads to move inwardly into engagement with the wheel. The brake is compact and efficient in design.
