A self-adjusting actuation mechanism is disclosed for use in a cable actuated system, such as a bicycle caliper brake system. The actuation mechanism includes a housing and a lever pivotally attached to the housing. A cable assembly is provided for operating an actuated mechanism and the cable assembly includes a sheath and a cable slidably positioned within the sheath and attached to the lever wherein actuation of the lever causes the cable to move in a first direction. An abutment member is supported within the housing in engagement with an end of the sheath and the abutment member is mounted for movement relative to the housing in a second direction opposite to the first direction in response to actuation of the lever whereby the effective length of the sheath is increased.
