The automobile braking system can effectively shorten the braking distance and braking time. The shorter the braking distance, the higher the efficiency of the braking system and the better the safety performance. So what factors will affect the braking distance?
1. The weight of the car affects the braking distance to a certain extent
The heavier the car, the greater the inertia and the relatively longer braking distance. Therefore, the weight of the car can also affect the braking distance to a certain extent. But this does not mean that heavier cars require longer braking distances than lighter cars. For example, some performance cars are much heavier than domestic A-class cars, but the braking performance is relatively better. Generally speaking, there are two situations: no-load and full-load. Detecting the braking distance of a car refers to the no-load situation.


2. Instantaneous speed before braking (initial speed)
That is, the speed of the vehicle before braking. Generally speaking, the faster the speed, the longer it takes for the vehicle to stop completely and the longer the braking distance.
3. The suspension system has a certain influence on the braking distance
In fact, the car suspension system has a certain influence on the braking distance. When the car’s suspension system brakes, the car’s center of gravity will move forward, causing the car’s front suspension to over-compress, thereby increasing the load on the front suspension. At this time, the braking effect of the rear wheels will be weakened, resulting in an increase in the braking distance.
4. Braking system
The brake system is a series of special devices used to make the outside (mainly the road) exert a certain force on certain parts of the car (mainly the wheels), so as to achieve a certain degree. Generally, it mainly consists of two parts: the brake control mechanism and the brake. The working state of the braking system also directly affects the braking distance of the car. For example, whether the brake disc (brake disc) is new or old, the brake fluid (brake fluid) is consumed, and whether frequent braking causes heat attenuation. Therefore, the brake system must be checked and maintained regularly before driving.
5. Road surface roughness
This is also easy to understand. If the same car brakes at the same initial speed, the braking distance required for asphalt and snowy roads will definitely be different.
