Difficulty: EasyBraking Systems and ABS

You are driving a car fitted with anti-lock brakes (ABS). In an emergency situation, how should you apply the footbrake to bring the vehicle to a halt safely?

  1. A
    Pump the footbrake pedal repeatedly on and off until the car stops
  2. B
    Apply the parking brake gently while pressing the footbrake with light pressure
  3. Press the footbrake pedal firmly and continuously until the vehicle has completely stoppedAnswer
  4. D
    Press the clutch pedal down first and coast while applying gentle brake pressure

Answer

Press the footbrake pedal firmly and continuously until the vehicle has completely stopped
In a vehicle equipped with an Anti-lock Braking System (ABS), the driver must apply prompt, firm, and sustained pressure to the footbrake pedal throughout an emergency stop. The ABS system monitors wheel speed sensors and automatically modulates hydraulic pressure rapidly to prevent wheels from locking, allowing the driver to steer around hazards while braking at maximum capacity.

Step-by-Step Solution

1
Identify the vehicle braking technology and emergency requirement
The car is equipped with an Anti-lock Braking System (ABS) and must stop in the shortest possible distance.
ABS is designed to prevent wheels from locking under heavy braking, allowing the driver to retain steering control.
2
Select the correct emergency braking technique for ABS
Apply immediate, hard, and uninterrupted pressure to the footbrake pedal.
ABS requires sustained hydraulic pressure to engage its automated sensors and rapidly modulate braking pressure across the wheels.
