Anti-lock braking systems (ABS) help prevent wheels from locking up and the vehicle from skidding during heavy braking. ABS uses sensors to monitor wheel speed and quickly adjusts brake pressure to each wheel to maintain traction. It helps drivers maintain control and stability when braking heavily or in emergency situations. ABS has made braking safer and helped reduce accidents by preventing skids.

2. Anti-lock braking system (ABS) is an automobile safety system that
allows the wheels on a motor vehicle to
maintain tractive contact with the road surface according to
driver inputs while braking, preventing the wheels from
locking up (ceasing rotation) and avoiding
uncontrolled skidding. It is an automated system that uses the
principles of threshold braking which were practiced by skilful
drivers with previous generation braking systems. It does this
at a much faster rate and with better control than a driver could
manage.

3.  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.

2] Three Wheel Channel

11.  Maintain directional stability in steering
during heavy/sudden braking.
 Safe & Effective
 Absorbs unwanted turbulence shockwaves
 Easy Fault/Failure detection by the vehicle
owner
 Automatic change of brake fluid pressure in
each wheel

12.  Very Costly
 Maintenance of a Car equipped with ABS is
required more.
