ABSTRACT:
A bicycle caliper brake assembly comprising a pair of pivotal calipers respectively having bosses rotatably fitted on a support shaft as interposed between an intermediate flange of the shaft and a double nut adjustably screwed on the shaft, the bosses being axially movable relative to each other on the shaft to assume their respective preassembled and assembled positions, one of the calipers being formed with a projecting portion which engages the other caliper to prevent both calipers from pivoting away from each other more than a predetermined amount when the bosses assume the assembled position but which disengages from the other caliper to allow both calipers to pivot away from each other more than the predetermined amount when the bosses assume the preassembled position, a coil spring system completely enclosed within the bosses for urging the calipers to pivot away from each other when the bosses assume the assembled position, wherein the spring system is maintained in a state for torsional energization even when the bosses assume the preassembled position.
