Final answer:
In an emergency stop with ABS brakes, one should apply firm, continuous pressure to the brake pedal; the ABS system will prevent lock-up and maintain steering control. Do not pump the brakes manually or take your foot off the pedal due to noise.
Step-by-step explanation:
When stopping in an emergency with ABS brakes, the recommended action is to apply firm, continuous pressure to the brake pedal. ABS, or Anti-lock Braking System, is designed to prevent the wheels from locking up and help maintain steering control during an emergency stop. The system uses sensors and a computer to monitor wheel speed and will pump the brakes for you if it detects the wheels are about to lock. This allows the driver to focus on steering to avoid obstacles.
It is not advisable to pump the brakes manually, as the system is already doing this at a much faster rate than a human could. Removing your foot off the brake pedal when you hear brake noise during a stop with ABS is not recommended, as the noise is a typical part of the system's operation. Moreover, while ABS is a powerful tool for helping maintain control, one should not rely solely on the brakes; drivers must also use evasive maneuvers to avoid obstacles when necessary.
