How long is the life of car brake pads? The main reason for the obvious difference between the theoretical service life and the actual service life of the brake pads is that the driving habits and road conditions are different. Frequent braking, heavy braking lightly, and long-term braking are all bad driving habits. .After buying a new car, there is no need to limit the time, and inspections should be carried out regularly.

Asbestos-free organic NAO type brake pads mainly use glass fiber and aramid fiber as reinforcement materials, which can achieve good braking effect at any temperature, and can prolong the service life of the brake disc because it is not metal. In general, the same model should be replaced in principle.

If conditions permit, it is recommended to buy a set of ceramic fiber brake pads. It should be noted that the material of the brake pads is not easy to be too hard, and the coefficient of friction between the brake pads and the brake disc must be considered. , If the brake pads are too hard, it is easy to cause excessive wear of the brake disc, which is the driving level of the person and the habit of using the brakes, as well as the normal road conditions of the driver.

The three factors are the most important factors that determine the life of the brake pads. Some people usually like to step on the brakes, while some people don't like to step on the brakes. If you can't tell when the brake pads need to be replaced, you can go to the repair shop to find a repairman, or check it during maintenance.

Of course, the original factory also has low-limit reminders, such as lightly stepping on the brakes, there will be sharp and piercing metal scraping sounds, and the car will not turn if it is dead, so the danger is not great. Straight way. Additionally, ABS is now standard, with ABS brakes providing steering once the front wheels are locked. Taking into account the differences in different working conditions, different driving styles and different vehicle configurations.

The first replacement time of the brake pads of different models is completely different. For the division, car companies have reserved technical means at the beginning of the brake system design, so that car owners can decide when to replace the brake pads according to their actual situation. Maintenance intervals, dashboard prompts, and the theoretical design life of brake pads are not criteria for judging the replacement of brake pads.

The most reliable criterion is to look at the thickness of the brake pad friction material. Considering that it is impossible for many people to stare at the brake pads all the time, you should pay attention to the following situations, that is, pay attention to the brake pads, and even the brake pads. replace. Don't forget to run 200-500 kilometers.

Since the surface of the new brake pads is relatively smooth and the coefficient of friction is low, the braking effect cannot meet the design standard and the braking distance will be extended. No intentional access is required, just avoid slamming on the brakes while running. Physical and mechanical properties The physical and mechanical properties of friction materials must not only meet the processing requirements of friction materials.

It is also necessary to meet the strength requirements for the friction materials used to maintain good performance. For automobile clutch friction plates, the friction material is required to have good impact strength, compression strength, shear strength, good thermal conductivity and heat resistance, and the performance change with temperature should be small.

It should be noted that the friction coefficient of ceramic brake pads remains stable under high temperature conditions, which means that the brakes on downhill sections can still provide good braking effects even when they are stepped on for a long time, which greatly increases safety. Of course, ceramic brake pads also have disadvantages, such as expensive.

In addition, the performance of ceramic brake pads in low temperature and severe cold environments is not particularly good. With heavy wear, the pads become thinner, requiring the brake pedal to be depressed deeper to engage the pads with the discs, and then increased depth again to achieve the desired stopping power. The thinner the brake pads, the longer the pedal travel, which is a visual reference for when you need to replace them.

For models without such an electronic alarm, some brake pads are equipped with worn steel plates, and the scraping sound of the steel plates and brake discs reminds the driver that the brake pads are needed. should change. Of course, in addition to these, the most important thing is that the maintenance personnel should check the remaining thickness of the brake pads every time they are repaired. If there is no brake on the first leg, it is prone to accidents.

Brake pads are generally composed of iron linings and friction materials. Don't wait for the friction materials to wear out before changing the shoes.
