The document discusses the transition from drum brakes to disc brakes and the importance of anti-lock braking systems (ABS) in modern vehicles. It explains how ABS prevents wheel locking and skidding, which can lead to uncontrolled driving and accidents. The conclusion advocates for making ABS mandatory in all vehicles due to its critical role in enhancing safety during braking.

2. Introduction
In recent years, with advancement in design &
technology, disc brakes are fast replacing drum brakes.
ABS was firstly developed for aircrafts but now it is used
in cars and trucks to prevent wheels from slipping and
skidding.

3. What is ABS ?
• “An anti-lock brake system is a
feedback control system that
modulates brake pressure in
response to measured wheel
deceleration, preventing the
controlled wheels from becoming
fully locked.”

4. What is Locking and Skidding ?
• Locking is referred to the
scenario where the Wheels Stops
spinning
• Skidding is to slide forward under
the force of momentum after
forward motion has been braked.

5. Effects of Skidding
• Uncontrolled driving
• Poor Traction Control
• Wheel Burn
• Increased chance of
accidents

6. Comparison of ABS and no-ABS
• Uncontrolled braking
• No grip
• More chance of accident
• Braking and steering
• Allows traction control
• Reduced chance of accidents
• Braking on slippery surface
No-ABS WITH ABS

7. Comparison of ABS and no-ABS

8. How it Works

9. ABS Components
• Wheel speed sensors.
• Brake calipers.
• A hydraulic motor.
• Some pressure release
valves.
• ECU

10. Conclusion
Because of its role in preventing the wheels from
locking and better steering control during braking,
Anti‐lock Braking System should be made
mandatory for all vehicles.
