In a vehicle equipped with anti-lock brakes, pumping the brake pedal will cause which result?

Explanation:
When a vehicle has an anti-lock braking system, the pedal should be pressed firmly and held. The ABS continuously modulates brake pressure to prevent wheel lock and achieve the greatest possible deceleration. Pumping the pedal disrupts this continuous pressure and can interfere with the ABS’ ability to apply maximum braking force, which often results in a less effective stop. So, the correct approach is that pumping reduces braking effectiveness, rather than improving it.
