The document discusses the anti-lock braking system (ABS). It begins by introducing brakes and their two main types - drum and disc brakes. ABS was first developed for aircraft in 1929 and helps prevent wheel lockup during emergency stops. The key components of ABS are a hydraulic control unit, brake modules, and wheel sensors. ABS works by constantly monitoring wheel speed and controlling hydraulic pressure to each wheel. It provides safety and steering control benefits during emergency stops. While improving braking on slippery surfaces, ABS also has drawbacks including higher costs and maintenance requirements.

- 2. BRAKES-INTRODUCTION Brakes are the mechanical aids which help in the deceleration of moving component, often used in terms of wheels of automobiles. Brakes are of two types, depending on principle of application: Drum Disc Brakes Brakes
- 3. DRUM BRAKE
- 4. DISC-BRAKE
- 5. ABS-OVERVIEW The ABS was first developed for use in aircraft in 1929 by a French engineer, GABRIEL VOISIN. It is an aid provided in the disc brakes for improved functionality. The ABS is a system that prevents wheel lock up by automatically modulating the brake pressure and provides an opportunity for the driver to steer the vehicle during an emergency stop.
- 7. ESSENTIAL COMPONENTS OF ABS An ABS system always consist of the following components: Hydraulic Control Unit Anti-Lock Brake Module Speed or wheel Sensors (front and rear)
- 8. How ABS works? 1.CONTROL UNIT Constantly monitors the wheel speed. 2.MODULATOR Controls hydraulic pressure at each wheel. 3.WHEEL SENSORS Control unit gets information about wheel speed from wheel sensors.
- 9. Types Of ABS Four-channel,Four-sensor ABS. Three-channel,Three-sensor ABS. One-channel,One-sensor ABS.
- 10. SAFETY The ABS system is an add-on in the age old braking technology, it is worth to mention that in some vehicles an ABS operates only when the brakes are applied with huge force in order to stop the vehicle in emergency. Most of the ABS controls are a ‘failsafe’ model .
- 11. APPLICATIONS In almost all the cars exclusively in sedan and SUV versions. In India, Apache 180 and Honda CBR250 comes with ABS. In some the small jet planes ABS is used. Maruti Suzuki swift desire uses powerful ABS.
- 12. ADVANTAGES OF ABS The ABS improves the steering control during the emergency stops. It fulfills the motive of stopping in the shortest possible distance. During the slippery and wet surfaces it improves the brake efficiency. Traction control.
- 13. DISADVANTAGES It is very costly. Maintenance cost of a car equipped with ABS is more. However, on loose surfaces like gravel or snowcovered pavement, an ABS can significantly increase braking distance, although still improving vehicle control.
- 14. Conclusion Statistics show that approximately 40 % of automobile accidents are due to skidding. These problems commonly occur on vehicle with conventional brake system which can be avoided by adding devices called ABS. If there is an ABS failure, the system will revert to normal brake operation. Normally the ABS warning light will turn on and let the driver know there is a fault
