ABSTRACT:
A bicycle brake device brakes a wheel by pressing first and second opposing brake shoes against the wheel in response to operation of a control cable having an inner cable that moves in first and second directions relative to an outer casing. The first brake link includes a first support component for swingably mounting the first brake link to the bicycle, a first shoe attachment component, and an outer stop component for fixing the outer casing of the control cable. The second brake link includes a second support component for swingably mounting the second brake link to the bicycle and a second shoe attachment component. An inner cable receiving mechanism is coupled to the second brake link for receiving the inner cable so that the second brake link moves in response to movement of the inner cable, wherein the inner cable receiving mechanism includes a movement variation mechanism for varying the rate of movement of the second brake link per unit movement of the inner cable. A transmission mechanism extends between the first brake link and the second brake link so that movement of the inner cable causes movement of both the first brake link and the second brake link.
