To achieve maximum efficiency from ABS braking, what should you avoid doing?

Answer: B — Pumping your brakes.

When utilizing Anti-lock Braking System (ABS) brakes, one of the key practices to maximize effectiveness is to avoid pumping the brakes. ABS is designed to prevent the wheels from locking up during hard braking, which helps maintain steering control. When a driver pumps the brakes, it interrupts the system's function, preventing it from applying braking pressure optimally. The system automatically modulates brake pressure, allowing the driver to maintain control of the vehicle while stopping. By pumping the brakes, you could inadvertently cause the system to react less effectively, resulting in a longer stopping distance and potentially losing control of the vehicle. Therefore, allowing ABS to function as intended—by applying firm, steady pressure on the brake pedal—ensures better vehicle control and stopping performance.
