ABSTRACT:
A pedal crankshaft operated actuator for a bicycle brake is formed by a yoke having a jaw engageable with one side of the crankshaft, a link pivotally connected to the yoke and having a jaw engageable with the other side of the crankshaft, and a pair of light spring coils surrounding the crankshaft and having a bight engaging the link outwardly of the jaw so that rotation of the crankshaft in a reverse direction locks the spring to the crankshaft and causes the jaws of the link and the yoke to seize the crankshaft. The link folds relative to the yoke to enable the assembly to be inserted into the pedal crankshaft housing, until a lever arm attached to the yoke drops through an aperture in the housing.
