An attempt has been made to solve the braking problem during hard braking. In case of motor bike, It has been seen that when the driver has to stop the motorbike immediately, he becomes confused which brake should applied and then he uses either front brake or rear brake or both brake and due to this an unbalanced is occur between the wheel and caused the accident. To solve this problem a single actuating braking system can be used. In this braking system, the front and rear hydraulic brake are operated by only single actuating system that is the brake pedal assembly. The purpose of the single actuating braking system is for the locking of both front and rear wheel at the same time without slipping and skidding. Since both the brake front and rear are operated by the tandem master cylinder, the pressure to the both calipers will be equal, so the both wheels can be locked and stop at the same time. The design of this braking system increases the simplicity of the actuating system. Since this braking system has only one actuating system, the overall cost is reduced. A tandem master cylinder can be used since it has two outlet valve primary and secondary which will be used for front and rear brake caliper respectively. Also the braking force, braking distance and time will be calculated during braking.

Key words: single actuating system, braking force, braking distance and braking time.
