How to Operate ABS Anti-lock Braking System?
3 Answers
The correct usage method of ABS anti-lock braking system is as follows: 1. Many drivers believe that the ABS anti-lock braking system is designed to enhance braking force and shorten braking distance, but in fact, it may also result in longer braking distances. 2. Its true function is to ensure that the wheels do not completely lock up during emergency braking. 3. In emergency situations, the brake pedal must be fully depressed to activate the ABS system. At this point, the brake pedal may vibrate slightly and produce some noise, but it should not be released, as this indicates that the ABS system is functioning properly.
When I first started driving, I didn't know how to use ABS properly. Later, during an emergency situation, I slammed on the brakes and heard a clicking sound from the pedal, with my whole foot bouncing. Don't panic—this is just ABS doing its job. You just need to keep pressing down firmly without letting up. I looked it up specifically: this system automatically performs pulse braking dozens of times per second when the wheels are about to lock up, much faster than even an experienced driver can. Remember, triggering ABS in rainy weather is especially useful, as you can clearly feel that the steering wheel still responds. However, on gravel roads, ABS is less effective—on such surfaces, locked wheels actually stop the car faster. Normally, when you start the car, the yellow ABS light on the dashboard will briefly illuminate and then turn off. If it stays on, it means there's a system malfunction that needs repair.
Last time on a mountain road, I almost rear-ended someone and truly witnessed the power of ABS when I slammed the brakes hard. Those of us used to driving old cars are accustomed to pumping the brakes, but with ABS-equipped vehicles, you just stomp the pedal to the floor in an emergency, and the system takes over. You'll feel the pedal vibrating intensely and hear rhythmic clicking sounds from the steering wheel—don't lift your foot or pump the brakes at this point. ABS is actually quite smart; it monitors all four wheels using wheel speed sensors and immediately releases the brake on any wheel that's rotating too slowly. This is especially noticeable on snowy roads—I've tried locking up wheels in a non-ABS car and just slid straight, whereas with ABS you can brake and steer simultaneously. However, I recommend regularly cleaning the wheel speed sensors, as mud buildup there can interfere with their operation.
