The document discusses the components and operation of an anti-lock braking system (ABS). ABS prevents wheel lockup during hard braking by using sensors to detect wheel speed, allowing a computer to quickly modulate brake pressure and keep the wheels rolling. The key components are wheel speed sensors, brake calipers, a hydraulic motor, and an electronic control module which coordinates pressure based on sensor readings to maintain stability and steering control during emergency stops.

3. Panic braking without ABS

4. ABS:- Anti-lock Braking System
 The skidding and loss of control was caused by the locking of wheels
 The release and reapply of the brake pedal will avoid the locking of
the wheel which in turn avoid the skidding
 ABS operates by preventing the wheels from locking up during
braking

5. Main components in ABS
 wheel speed sensors
 Brake calipers
 A hydraulic motor
 A quick thinking computer (BCM and ECU) which coordinates the whole
process

6. Wheel Speed Sensor-WSS
 It measure instantaneous speed of a wheel and deliver the value to the ECU
 It consist of a toothed ring and a pickup

7. ABS Sensors In Bike

8. Brake Calipers
 Action of the brake caliper control the wheel spin

9. Hydraulic motor
 analyzed data from the ECU causes valves within the ABS pump to open and close
as rapidly as necessary to control fluid pressure in the specific braking circuit

10. BCM and ECU
Brake Control Module and Electronic Control Module
 embedded system in automotive electronics that controls one or more of the electrical systems or
subsystems in a vehicle

11. ABS warning lamp
 ABS warning lamp will glow on your dashboard or cluster panel when the ABS is failed

12. Panic braking with ABS

14. Advantages of ABS
 Stopping distance is less
 Can be steer the vehicle during braking
