Question

Difficulty: MediumBraking Systems and ABS

When an Anti-lock Braking System (ABS) activates during heavy braking, the driver should immediately ease off the brake pedal as soon as pedal pulsation is felt.

Answer: Answer

Answer

False
The statement is false. When an Anti-lock Braking System activates, rapid hydraulic pressure modulation produces noticeable vibration and pulsation through the brake pedal. Official DVSA driving standards state that drivers must keep their foot pressed down firmly and continuously on the brake pedal until the vehicle comes to a complete halt or danger has passed, allowing the system to prevent skidding and retain steering capability.

Step-by-Step Solution

1
Identify the cause of pedal vibration and pulsing under heavy braking in an ABS-equipped vehicle.
Pulsation is normal feedback caused by the ABS rapidly opening and closing hydraulic valves to prevent the wheels from locking up.
Understanding standard system feedback prevents misinterpreting ABS activation as a mechanical failure.
2
Evaluate the correct driver action in response to ABS activation.
The driver must maintain firm, continuous pressure on the footbrake without easing off or pumping the pedal.
Easing off pedal pressure reduces overall braking effort and disables the continuous anti-lock intervention needed to steer around hazards safely.
