  • Patent number: 8469156
    Abstract: A sequential brake control device for a cycle has a sliding connector and a front delaying and anti-lock spring set to serve to sequentially actuate a brake. A left lever cable and a right lever cable are commonly connected to the sliding connector. A front brake cable passes through the sliding connector and the front delaying and anti-lock spring set and is mounted in a front brake cable block abutting against the front delaying and anti-lock spring set. A rear brake cable may alternatively pass through the sliding connector and a rear suspension spring and is mounted in a rear brake cable block abutting against the rear suspension spring. When one or both brake levers are squeezed, a rear wheel is stopped before the front wheel does. The front and rear wheels are slowed down in speed first when a brake is applied and fully stopped at a lower speed of the cycle.
