Question

Difficulty: MediumABS and Electronic Stability

When an Anti-lock Braking System (ABS) activates, the driver should rapidly pump the brake pedal to assist the system in maintaining vehicle control.

Answer: Answer

Answer

False
The statement is false because the driver must maintain firm, continuous foot pressure on the brake pedal throughout the stop. The ABS system automatically modulates the braking force at a rate much faster than human capability; releasing the pedal interrupts this process.

Step-by-Step Solution

1
Determine the operating principle of an Anti-lock Braking System (ABS).
ABS automatically monitors wheel rotation and pulses the brake calipers multiple times per second to prevent lockup.
Understanding active safety system operation clarifies appropriate driver inputs during emergency maneuvers.
2
Evaluate the mechanical consequence of manual cadence braking on an ABS-equipped vehicle.
Manually releasing the footbrake dumps hydraulic pressure and cancels the electronic system's optimal threshold braking.
The correct procedure during ABS activation is to press the brake pedal firmly and hold continuous pressure while steering as necessary.
