In the specification and drawing a new brake system and a two-wheeled vehicle using the same are described. The new brake system includes a first brake to apply a first brake force on a first wheel of a vehicle and transfers the first brake force to physically actuate a second brake to brake a second wheel of the vehicle. A new-designed cantilever brake is disclosed to transfer the first brake force to actuate the second brake.

1. An apparatus in direct physical contact with a rear brake mounted on a bicycle having a front wheel on a front portion of the bicycle and a rear wheel on a rear portion of the bicycle, the bicycle having a front brake for slowing the front wheel and the rear brake for slowing the rear wheel, the apparatus comprising a slider in direct physical contact with a brake pad of the rear brake;a slider guide slidably connected to the slider, the slider guide in direct physical contact with a rear brake arm of the rear brake; anda wire core in direct physical contact with both the slider and the front brake. 2. The apparatus of claim 1, wherein the wire core of the front brake cable actuates the front brake of the bicycle. 3. The apparatus of claim 1 wherein the slider slides against a portion in the slider guide. 4. The apparatus of claim 1 wherein the brake pad is aligned with a rim portion of the rear wheel of the bicycle. 5. The apparatus of claim 4 wherein friction between the rim portion of the rear wheel and the brake pad causes the slider to slide against the slider guide. 6. The apparatus of claim 5 wherein the movement of the slider causes the wire core of the front brake cable to move. 7. The apparatus of claim 6 wherein the front brake of a bicycle is actuated by a movement of the wire core. 8. The apparatus of claim 1 wherein the front brake is a disk brake coupled to the front wheel of the bicycle. 9. An apparatus in direct physical contact with a rear brake mounted on a bicycle having a front wheel on a front portion of the bicycle and a rear wheel on a rear portion of the bicycle, the bicycle having a front brake for slowing the front wheel and the rear brake for slowing the rear wheel, the apparatus comprising: a slider in direct physical contact with a brake pad of the rear brake;a slider guide in direct physical contact with a rear brake arm of the rear brake, the slider guide slidably coupled to the slider; anda front brake actuator in direct physical contact with both the slider and the front brake. 10. The apparatus of claim 9, wherein the front brake actuator actuates the front brake of the bicycle. 11. The apparatus of claim 9 wherein the slider slides against a portion in the slider guide. 12. The apparatus of claim 9 wherein the brake pad is aligned with a rim portion of the rear wheel of the bicycle. 13. The apparatus of claim 12 wherein friction between the rim portion of the rear wheel and the brake pad causes the slider to slide against the slider guide. 14. The apparatus of claim 13 wherein the front brake actuator includes a wire core and the movement of the slider causes the wire core to move. 15. The apparatus of claim 14 wherein the front brake of a bicycle is actuated by a movement of the wire core. 16. The apparatus of claim 9 wherein the front brake is a disk brake coupled to the front wheel of the bicycle. 17. A method comprising: providing a bicycle having a front wheel on a front portion of the bicycle and a rear wheel on a rear portion of the bicycle, the bicycle having a front brake for slowing the front wheel and a rear brake for slowing the rear wheel;providing a slider in direct physical contact with a brake pad, a slider guide coupled to the slider and a wire core coupled to the slider, the slider is in direct physical contact with the rear brake; andcompressing the brake pad against a rim portion of the rear wheel of the bicycle that is rotating;wherein friction between the brake pad against the rear wheel causes the slider to slide against the slider guide in a first direction; andwherein the sliding movement of the slider in the first direction pulls the wire core to actuate a front brake of the bicycle. 18. The method of claim 17 further comprising: skidding the rear wheel against the ground;sliding the slider against the slider guide in a second direction; andreleasing tension in the wire core sliding the slider against the slider guide in a second direction to de-actuate the front brake. 19. The method of claim 17 further comprising: preventing the front wheel coupled to the bicycle from skidding against the ground while the bicycle is moving by releasing tension in the wire core sliding the slider against the slider guide in a second direction to de-actuate the front brake. 20. The method of claim 17 further comprising: actuating a brake lever coupled to the bicycle;moving a rear brake cable; andactuating a rear brake to compress the rear brake pad against the rim portion of the rear wheel.
