COMBINED BRAKING SYSTEM AND ANTI LOCKING BRAKING SYSTEM

                       COMBINED BRAKING SYSTEM

It is preferred that both front and rear brake are applied simultaneously but most of driver can not use them simultaneously in good way.Combined braking system is interlocked braking system.It gives easy comfortable and controlled braking system.
               It reduces braking distance and increases stability during braking.

WORKING PRINCIPLE

                                                                   fig:CBS schematic diagram                                                                                  

                             main components are as follows:

(1)calliper

(2)delay valve

(3)pressure control valve

   The rear hydraulic brake is provided with pessure control valve and delay valve is provided with front wheel.While applying the rear brake hydraulic pressure from master cylinder is applied to pressure control valve and delay valve. This pushes the piston in rear brake caliper to activate the brake.By applying rear brake harder the hydarulic pressure applied to delay valve increases this opens the delay valve and front brake caliper is activated.The pressure control valve at that pressure starts to close and prevents wheel from lockup.                                                                                                                                                          

                                             It is difficult for a less experienced drive to apply both brakes in a proper proportion.ABS takes care of this because it automatically applies brake to both of the wheel in proper ratio.so even a less experienced driver can also drive it safely.It reduces braking distance,increases stability of bike and reduces chance of accident.Now modern bikes are provided with combined braking system.

                                             Combined braking system is no way connected to anti locking braking  system which stops the wheel from locking. 

                                            ANTI LOCKING BRAKING SYSTEM

An anti-lock braking system (ABS) is a skid protection system used in automobile that permits the wheels of the vehicle to maintain tractive contact by preventing slip while braking, preventing the wheels from locking up thus prevent from skidding It is an automated system that uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate and with better control than many drivers could manage

                                   Main advantage is following:

(1)It prevents wheel from slip so traction is posssible at every instance.

(2)Reduces braking distance
