The ABS Principal

Wheel lockup

Skidding

Loss of traction

& vehicle control

Reduce steering ability

Slides out of control

With ABS system, the driver can brake hard, take the evasive action and still be in control of the vehicle in any road condition at any speed and under any load

Types of ABSFour channel- The best scheme- Provide greater safety- Most modern cars use this type

Three channel- Individual control of front wheels- The rear wheels are monitored together- Found on pick up trucks

Advantages

Maintain directional stability

Control over steering during brakingSafe & Effective

Brake fluid pressure change automatically

From statistics approximately 40% of automobile accidents are due to skidding

Cars with ABS are up to 65% more likely to be in fatal crashes than cars without ABS

ABS is a live saving technology which allows steering while braking heavily
