WHAT IS ABS??It is a Braking system arrangement in vehicles for safe riding during sudden or heavy braking.It maintains a balance between the wheel speed and the vehicle speed to avoid skidding during heavy braking.It ensures that there is less TRACTION loss in the tyres of the vehicle.

SPEED SENSORThe anti-lock braking system needs some way of knowing when a wheel is about to lock up. The speed sensors, which are located at each wheel, or in some cases in thedifferential, provide this information.

VALVESThe valve is used to release the pressure from the brakes. On some systems, the valve has three positions :In position one, the valve isopen; pressure from themaster cylinderis passed right through to the brake.In position two, the valveblocksthe line, isolating that brake from the master cylinder. This prevents the pressure from rising further should the driver push the brake pedal harder.In position three, the valvereleasessome of the pressure from the brake.

Hydraulic pumpSince the valve is able to release pressure from the brakes, there has to be some way to put that pressure back. That is what the pump does; when a valve reduces the pressure in a line, the pump is there to get the pressure back up.CONTROL UNITThe controller is a computer in the car. It monitors the speed sensors and controls the valves.Component Diagrams
