The brake system is one of the very important components of the lighting vehicle . The service life of the front brake pads is 3 to 50,000 kilometers, and the trial period of the rear brake pads is 6 to 80,000 kilometers. The replacement cycle of the brake pads depends on the specific conditions of the vehicle usage, loading conditions, and type of brake pads. The use of brake pads in real life is that a brand's brake pads can use 50,000 to 80,000 kilometers in one car, and only 30,000 kilometers can be replaced in another car. There are many factors that affect the brake pads of lighting vehicles. For example, the frequency of parking starts in urban areas is high, and the replacement cycle of brake pads is much shorter than that of long-term running vehicles. However, in vehicles that travel in urban areas, the replacement cycle of vehicle brake pads with large vehicle load volumes is shorter than that of vehicles with small capacity. It can be seen from the above text that the brake pads have not been replaced during a certain period of time, but I will often check the use of the brake pads. When is the replacement of lighting brake pads more suitable and suitable? The thickness of the friction material on the disc brake pad can not be less than 2 mm, and the friction material on the corresponding drum brake pad can not be less than 1.5 mm. Tests have shown that brake pads wear and peel off faster after 1.5 mm. When replacing the brake pads, I must pay attention to the fact that the left and right tires must be replaced at the same time. A vehicle such as an inspection vehicle equipped with a warning light will only light when the friction material is less than 3.5 mm. Normally, we will turn the brake warning light on the dashboard of the lighting vehicle as the basis for changing the brake pads. In fact, it is very dangerous to replace it at this time. Although all vehicles have warning lights, some of them are sensitive to the thickness of the brake pads, while others are only bright when the brake pads are in full friction. If it is the second case, it is already the state that the metal base of the brake pad rubs the tire. In life, it is often not until the brake pads can no longer be used. It is not safe for both the vehicle itself and the driver's friends. We must learn more about brake pads and prepare for replacing brake pads.
