ABSTRACT:
An operating wire control device for a brake system having an adjust lever rotatable in accordance with the stroke of an inner wire. An adjuster is rotatable by the rotation of the adjust lever and an adjust bolt is movable upon rotation of the adjuster to alter the relative length of the inner wire and an outer wire. The adjust lever comprises a first lever having an abutment member for detecting the stroke of the inner wire and a second lever having a ratchet pawl engaged with a ratchet tooth on a ratchet wheel formed integrally on the adjuster. The second lever is longer than the first lever. An adjust lever spring is provided between the first and second levers, while a return spring extends between the second lever and a housing. The adjust lever spring has a spring force which becomes smaller than that of the return spring when the inner wire has been pulled beyond a prescribed stroke.
