177. ABS
ABS (Anti-lock Braking System) is an active safety system that helps prevent a vehicle's wheels from locking during hard braking. It automatically adjusts braking pressure at individual wheels so that they continue to rotate sufficiently to maintain directional control.
When ABS operates, the driver may feel rapid pulsing or vibration through the brake pedal. The driver should normally maintain firm braking pressure and continue steering towards a safe path rather than repeatedly releasing and reapplying the brake.

What does ABS do?
ABS helps prevent the wheels from locking during heavy braking. By controlling wheel slip, it helps the driver retain steering control while braking strongly.

Does ABS always reduce braking distance?
No. The main purpose of ABS is to prevent wheel lock and help maintain vehicle control. Actual stopping distance still depends on speed, tyres, road surface, weather and other conditions.
