What should be noted for cars without ABS?
2 Answers
Cars without ABS require extra caution on slopes and complex road conditions, maintaining a low and steady speed is advisable. When descending slopes, use a lower gear and avoid continuous braking to prevent overheating of brakes which could lead to safety issues. Additionally, on slippery surfaces or at higher speeds, employing the technique of intermittent braking (pump braking) is necessary to achieve safe deceleration. How car ABS works: During braking, ABS rapidly assesses wheel lock-up status via speed signals from each wheel's sensor. It closes the normally open inlet solenoid valve for wheels beginning to lock, maintaining consistent braking force. If locking persists, the normally closed outlet solenoid valve opens, allowing brake pressure to rapidly decrease through a direct line to the brake fluid reservoir, preventing complete wheel lock-up due to excessive braking force. This keeps braking at the optimal point (20% slip rate), ensuring maximum braking efficiency and driving safety. Functions of car ABS: Maximizes brake performance, reducing braking time and distance; Effectively prevents vehicle skidding and fishtailing during emergency braking, ensuring excellent driving stability; Allows steering during emergency braking, maintaining good steering control; Minimizes intense friction between tires and road surface, reducing tire wear.
Driving a car without ABS, as a beginner, I really feel that braking requires extra caution. You can't just stomp on the brake pedal like in a car with ABS, otherwise the tires can easily lock up and skid, which is very dangerous. I recommend practicing the pumping technique first: in an emergency, quickly press-release-press the brake pedal, slowing down in stages, which helps maintain wheel rotation and steering control. Also, increase your following distance—at least two seconds more than usual—especially on rainy days or icy roads, where stopping distances can double. Checking the brake system is super important; I personally check the brake fluid level monthly and have a technician inspect the brake pad wear every six months. If the pedal feels unusually stiff, it might be a line issue, so get it fixed ASAP. Practicing emergency scenarios in an empty lot to get used to the car's reactions can significantly reduce the risk of accidents.
