Abstract
A caliper type brake for a bicycle, which includes brake members pivotally supported by a frame of the bicycle for supporting brake shoes adapted to be pressed to a rim of a wheel of the bicycle. Each of the brake members is shaped like a bell crank and has one end pivotally connected to the frame of the bicycle and the other end supporting the brake shoe. An operating radius between a pivotal point of each of the brake members and a point of the brake member on which a brake operating force acts is made as small as possible. The brake further inlcudes a generally V-shaped connecting rod whose ends are connected to the brake members, respectively for applying the brake operating force to the brake member, a pulley rotatably provided at an intermediate portion of the connecting rod, and an operating wire extending about the pulley and having one end fixed to the frame of the bicycle.
