What is the Appropriate Braking Distance?
1 Answers
Braking distance of 45-60 meters is appropriate. Suspension System: During emergency braking, the vehicle's center of gravity shifts forward, compressing the front suspension. If the front suspension lacks sufficient support, the excessive forward shift of the center of gravity can reduce the adhesion of the rear wheels, weakening their braking effect and increasing the braking distance. Some vehicles exhibit severe front-end dipping during braking, which is a sign of poor front suspension support. Vehicle Weight: The greater the weight of the car, the greater the inertia, making it harder to stop. Therefore, vehicle weight has a direct impact on braking distance. However, heavier cars do not always have longer braking distances than lighter ones. For example, some performance cars weigh significantly more than family A-segment cars but have much better braking performance, as factors like tires and braking systems also play a role. The influence of vehicle weight on braking distance is mainly seen in the same car under the same braking system—the greater the load, the longer the braking distance. Tires: Tires are the medium through which the braking system operates. The better the tire adhesion, the more braking force can be generated during braking, thereby shortening the braking distance. For general family cars, the main factor affecting braking distance is tire width. Wider tires have a larger contact area, providing greater braking force.
