Needless to say, the importance of the car's braking system. Car owners should be very aware that it will be troublesome to solve problems once they occur. The braking system generally includes the brake pedal, brake booster, brake warning light, handbrake, and brake disc. As long as there is any failure, sufficient attention should be paid to it. Take brake pads as an example. Although they do not need to be replaced too frequently, you must pay attention to the mileage or cycle when replacing them. If they are not replaced for too long, their performance will be affected to a great extent. So, how many kilometers should the brake pads be replaced? Do they have to be replaced by the original ones? Many car owners don’t know. Let’s find out today.

Although the replacement of brake pads is closely related to mileage, the two are not directly related. In other words, there are other factors that affect the replacement cycle of brake pads, such as car owners’ driving habits, car usage environment, etc. For the vast majority of ordinary car owners, brake pads can generally be replaced once every 25,000 to 30,000 kilometers. If your driving habits are good, you rarely step on the brakes, and the driving conditions are good, they are just used as upper brake pads. If you are commuting after work, you can appropriately extend the brake pad replacement cycle. In fact, car owners can also use the following methods to determine whether the brake pads need to be replaced.

First, you can check the thickness of the brake pads. The thickness of new brake pads is about 15 mm. After long-term use, the brake pads will become thinner and thinner due to wear. If you find that the thickness of the brake pads is only about one-third of its original value, which is about 5 mm, you can consider replacing the brake pads.

Secondly, you can also feel the wear degree of the brake pads by applying the brakes. If the brakes make a sizzling sound similar to the friction between iron plates during normal driving, it means that the brake pads have been severely worn and need to be replaced as soon as possible, otherwise the brakes may fail. Of course, this method is still more difficult than directly looking at the thickness of the brake pads, because there are many other noises when the car is driving, such as wind noise and tire noise. These noises are likely to mask the sound of the brake pads when the brakes are applied. . In addition, for some veteran drivers with rich driving experience, they can also judge the degree of wear of the brake pads by the feeling of braking. If the brakes are soft and difficult to apply, and the braking distance is obviously longer, it also means that the brake pads need Replaced promptly.

So, when replacing brake pads, do we have to choose original ones? This is not necessarily true. The most important thing is to look at the quality and performance of the brake pads. As long as these two points are met, it is fine. Secondly, when replacing the brake pads, you should pay attention to the friction coefficient. If it is too high, it will easily cause the wheel to lock. If it is too low, it will cause the brake to fail. Choose a moderate friction coefficient. Of course, the comfort of the brake pads must also be considered. For example, some brake pads make a lot of noise when stepped on, and may even emit smoke, odor, dust, etc. Such brake pads are obviously unqualified and should be replaced as soon as possible.
