ABSTRACT:
Mechanisms are disclosed for actuating the conventional caliper brakes of bicycles by back pedalling the drive sprocket. In one embodiment, an overrunning clutch drives a cable drum which tensions an actuator cable for a caliper brake. In a further embodiment, a pawl riding on the drive sprocket of the bicycle extends a linkage which pulls a cable to actuate the caliper brake. In still another embodiment, a spiral gear is rotated upon back pedalling of the bicycle drive sprocket to tension a brake actuating cable.
