From the advent to the present, after more than a hundred years of development, the product quality and car manufacturing process have been improved, and a large number of new models with good quality and low price have emerged, which meet the travel needs of the vast majority of people.
For car owners, there is a clear contrast before and after buying a car, before buying a car, the understanding of the car is limited to the advantages and shortcomings of different brands, and after having a car, it will understand the state of the model structure and parts.
Although the car-making process has been improved, the car is still a product composed of many parts, and the car can be regarded as a toy assembled from "building blocks", which are other components with different functions.
For the car white, it may be understood that the drive system of the car, and its related parts are very important, once the drive system fails, the car will break down and stop, of course, with the continuous improvement of the level of car manufacturing, this situation is more and more rare, and the owner should pay more attention to the state of the wearing parts.
For the brake system, the brake pads play a key role, whether it is an electronic brake or a manual brake system, and finally the brake pads are required to brake, and as the car's driving range and service life increase, the state of the brake pads will also decline.
What are brake pads?
In the car's braking system, brake pads are very important components, although the brake system has completed the electronic development, but the working principle of the final step has not changed, the principle of braking comes from friction and energy conversion, the kinetic energy into heat energy.
The specific step is through the friction between the brake pads and the brake discs, and the kinetic energy is slowly converted into thermal energy, so as to reduce the speed of the car and finally achieve the purpose of stopping.
It can be seen that the brake pads play a key role in the parking process, when to replace the brake pads? Old driver: three identification methods can avoid "brake failure", these three cases should be replaced in time to replace the brake pads, to avoid the situation of brake failure.
Method 1: Observe the status of the brake pads
When the new car lands, the thickness of the brake pads is about 1.5CM, and the state of the brake pads in this case is very good, but with the increase in mileage and the frequency of the car, the state of the brake pads will slowly decline, and when the thickness of the brake pads is still 0.5 CM, it means that the brake pads should be replaced.
The state of the brake pads is not limited to the thickness, some ceramic brake pads will even appear cracks, in this case, it is necessary to replace in time, high-configuration models will even be equipped with a detection system, which can be decided whether to replace the brake pads through the prompts of the car.
Method 2: When braking, the direction is offset
Different drive types of vehicles, the degree of wear of the brake discs of the four wheels will be different, and the direction of the vehicle will be shifted when the brakes are stepped on, which indicates that one or more brake pads are seriously worn, especially some drivers who like to drift, which will accelerate the wear of the brake pads or brake discs.
Method 3: Observe the braking force
Different brands of car brake performance is different, some brands of brake system is more sensitive, light braking will play a very obvious braking effect, when the driving mile becomes longer, the braking distance and effect will be greatly reduced, when the braking distance is more than twice as long as before, indicating that the friction of the brake pads is decreasing, naturally to replace in time!
In fact, the brake pads do not have a unified replacement cycle, which is determined by factors such as brake frequency, road environment, driving habits and mileage, the majority of car owners should know how to judge, master the above three methods, timely replace the problematic brake pads, to avoid brake failure.
