ABSTRACT:
A caliper-type brake assembly for a bicycle, comprising at least one pair of opposed, generally complementarily configured elongate brake arm levers. Each brake arm lever supports adjacent a first end a bearing surface and adjacent a second, opposite end a braking pad to be urged against a sidewall of a wheel rim to be braked. Pivotal support means supports each brake arm lever on the bicycle adjacent the wheel rim and is disposed between the first and second ends of each brake arm lever, causing each brake arm lever to function as a first class lever. At least one pair of complementarily configured crank arm levers each has a first arm, a second arm, and a pivotal support adjacent an end of the first arm. Brake actuating devices secured adjacent the end of the second arm of each crank arm lever pivots the crank arm levers simultaneously about their pivotal support. Bearings supported on each crank arm lever intermediate its opposite ends engages the bearing surface of an associated brake arm lever causing each crank arm lever to function as a second class lever. Rotation of the crank arm levers about their pivots causes the brake actuating devices on each crank arm lever to act on the bearing surface of the associated brake arm lever to rotate the brake arm lever in a direction to urge its friction braking pad into engagement with the sidewall of the wheel rim to be braked.
