2. INTRODUCTION A  combined braking system  ( CBS ), also called  linked braking system  ( LBS ), is a system for linking front and rear  brakes  on a  motorcycle or  scooter . [1]  In this system, the rider's action of depressing one of the brake levers applies both front and rear brakes. The amount of each brake applied may be determined by a  proportional control valve . This is distinct from integrated brakes, where applying pressure to brake pedal only includes application of some front brake.

3. PRINCIPLE OF BRAKING Common principles on which a braking system depends when stopping a car is friction and heat. By applying resistance, or friction, to a turning wheel, a vehicle's brakes cause the wheel to slow down and eventually stop, creating heat as a byproduct. The rate at which a wheel can be slowed depends on several factors including vehicle weight, braking force and total braking surface area.

4. WHAT IS COMBI BRAKE SYSTEM? The most efficient way of braking is to apply the front and rear brakes simultaneously. But it is a practice, most two-wheeler riders have not mastered. The Combi Brake System in Honda two-wheelers enables you to use both brakes with just a lever^. It reduces the braking distance and improves stability while braking.

5. Honda Combi Brake with Equaliser , ensures distribution of Force between the Front and Rear Wheel at the same time, giving perfect balance to the rider. It ensures that rider with low expertise is also confident while braking. Simultaneous application of Front and Rear Brake leads to the most effective braking.

6. BASIC FUNCTIONING OF CBS Equalizer Equalizer is the brain of the system. Pressing the left lever activates the Equalizer, which distributes the braking force between the front and rear wheels simultaneously so that you can ride with the confidence of efficient braking in your hands .

7. WORKING OF CBS Combi -Brake system helps in achieving easier operation while braking. When the rider presses the rear brake lever, it activates both front and  rear brakes  simultaneously. This helps in safer braking and better control of the bike.

8. The Combi braking system is basically designed for small scooters. With the application of left lever , brakes is applied to both front as well as rear wheels The right lever applies the brakes on the front wheel only but as you press the left lever , it will apply brakes to both front and rear wheels with the help of Equalizer placed between front and rear wheels . Hence a high degree of deceleration can be obtained with a single operation of left lever .

9. COMBINED BRAKING SYSTEM ADVANTAGES Comparatively better & safe braking option for low priced and small capacity motorcycles. Cost effective feature for safe braking system. Helpful feature for armature, inexperienced and infrequent motorcycle users. It reduces the braking distance and improves stability while braking.

10. COMBINED BRAKING SYSTEM – DISADVANTAGES It somewhat puzzling for frequent and experienced motorcycle user. Not good for serous motorcyclist. Not good feature for high profile and high performance sports motorcycles . It’s not applicable for off road or stunt sports motorcycles. CBS is a mechanical feature; so it cannot be switched off.

11. ANTI LOCK BRAKING SYSTEM VS COMBINED BRAKING SYSTEM Considering the safety feature ABS is much more advanced and safe feature than CBS. But being an expensive feature it’s not a suitable option for low capacity and low priced motorcycles. Hence in such situation CBS can be a preferable option. But again CBS is not so comfortable for serious type or experienced motorcycle users.

12. Moreover considering situation and riding pattern ABS can be switch off or on. But in CBS it’s not possible. Apart from “BS” in both names, ABS and CBS are different in terms of purpose and application. For good and effective braking, brake should be applied on both the wheels simultaneously which the CBS ( Combi Braking system) does and stops the vehicle with lesser braking distance.

14. CONCLUSION Thus with CBS, the necessary basis has been created for integrating additional safety functions beyond the basic functions of CBS, and for improving the performance of the existing functionality. A variety of assistant functions will continue to relieve the rider, as in passenger cars, and increase riding safety in the future.
