<p>A novel brake assembly is provided for a cycle. The bicycle is provided with at least one portion (22) having cavities (56, 76) therein, and the brake actuator (10) mounted on the bicycle, a pair of brake calipers (50, 72) mounted in the cavities (56, 76) and pivotally attached to the bicycle, a caliper-actuating body (40), and a motion transfer assembly (24) coupled to and movable by the brake actuator (10). The caliper actuating body (40) is connected to the motion transfer assembly (24). The calipers (50, 72) are provided with first and second arm portions (60, 62, 80, 82), each of the first arm portions having thereon a ramp surface (64) engaged with the body (40), and each of the second arm portions (62, 82) being configured to receive and retain a brake pad (68, 88). The calipers are pivoted by the caliper-actuating body, acting on the ramp surfaces in response to movement of the motion transfer assembly, so as to move the calipers in a direction that brings the brake pads into engagement with a wheel of the bicycle, so as to exert a braking force on the bicycle. Spring means (92) are provided to urge the calipers in a direction to move the brake pads away from the wheel.</p> |
