There are tens of millions of roads, the first one is safe. In driving safety, we are also very important for the maintenance and maintenance of the car. The most important thing is the maintenance and maintenance of the tire and brake system, because once the tire is bursting or If the brake fails, it may cause serious traffic accidents. In the previous article, Meow Brother has told you many changes in the tires. Today, Meow Brother focuses on how to judge whether the brake pads need to be replaced.

As shown in the figure below, although the brake pads are small but the internal organs are all available, the brake pads consist of two parts, one is the body, including the insulation layer, adhesive layer, backplane, muffler, etc., and the other is wear -resistant material. Materials, in popular terms, are the main part of the daily driving process of the car, about 1-1.5 cm thick. Small brake pads are affected by large pressure, and at the same time, compared with larger brake discs and other loss components, the cost of the brake pads is low, which is more suitable to replace frequently to ensure driving safety.

After understanding the structure of the brake pads, many friends will ask, so when should the brake pads be replaced? Due to the limitedness of wear -resistant materials in the brake pads, long -term wear will make the wear that can be worn less and less. Under normal circumstances, when the wear -resistant material has been consumed by two -thirds, it needs to be taken seriously. Although even if the wear -resistant material is exhausted, the brakes will not fail, but it will cause you to fall into the braking distance too long. Dangerous situation.

When driving at high speeds of the vehicle, because the speed of the vehicle is very high, it is likely that the car can not stop. The vehicle in front of the front rear -ended is caused to cause full responsibility for traffic accidents. The development of modern technology makes you no longer need to roughly estimate the time to replace the brake pads. Some more expensive cars will place the corresponding induction line in the brake pads. When the original brake pads reaches the critical point that cannot be worn continuously, the handbar -shaped icon will be displayed on the dashboard of the vehicle to replace the brake pads.

However, there is no sensing line in some cheap car brake pads, but the method of placing alarm iron next to the brake pads. When the friction material is worn to the limit value, the brake disc and the warning patch next to the warning patch will occur. Then, the sharp and harsh sound of iron and iron friction was made to remind the driver to check and replace the brake pads in time. If the driver does not pay attention to continuing to use at this time, although the brakes will not fail, the warning iron will continue to wear with the brake disc, and the brake disc will leave deep wear marks, causing the brake discs to be scrapped in advance.

Because everyone’s driving habits are different, it is unscientific to judge whether the brake pads should be replaced by driving mileage. The rude driving habits are grinded by 20,000 to 30,000 kilometers, and a good driving habit can even use more than 100,000 kilometers. In addition to judging whether to change according to the sensor reminder, you can also see the thickness of the brake pads through the spoke gap, you can roughly determine whether the brake pads need to be replaced.

“The car is not good, the brake is spiritual”. As a driver, we are obliged to pay attention to our own brake pads, combined with our driving habits to check and replace the brake pads in a timely manner to ensure our driving safety. Safety.
