When driving, you will inevitably hear some strange sounds from your car, such as the shaking sound of some glass windows, the harsh sound when braking, some unknown sounds and so on. This small series will introduce the abnormal noise generated by braking. In this case, don't panic. It's often better to change the brake pad.

There are four reasons for abnormal noise when braking, and each reason is inseparable from the brake pad.

When you choose to buy brake pads, do you care about the brand and quality of brake pads? If you don't care about these, you are likely to buy some low-quality or high hardness brake pads on a small and cheap basis. The material determines the quality of this brake pad. The quality of low-quality brake pads is poor, and the surface of brake pads is also more rough and uneven. When braking, the friction between the brake pad and the brake disc will produce a creaking noise.

If you often have to drive on some gravel roads, it is likely to be caused by the small gravel on the road. When the vehicle is driving, it will roll up the small sand and stone on the road. The sand and stone can easily enter between the brake pad and the brake disc. When stepping on the brake, it is not the brake pad that rubs first, but these sand and stone, and the abnormal noise will naturally occur. This situation is very similar to that when driving in rainy days and the water accumulated after the vehicle wades into the brake disc and brake pad, but the impact is different.

The two cases are quite different. They are both wear problems, but the root causes are different. Wear can be divided into normal wear and abnormal wear. The so-called normal wear is that the brake pads gradually become thinner with the increase of service time or driving mileage. Abnormal wear is that there are extremely sharp or hard objects between the brake pad and the brake disc, which will lead to abnormal loss of the brake pad and the brake disc in the process of braking, such as deep grooves in the brake disc, uneven wear of the brake pad, etc.

The brake pad has an alarm system, which means that when the brake pad is worn to a certain extent, an alarm will be sent to remind the driver that it is time to replace the brake pad. Some are electronic alarms, others are alarm pads. When they are worn to a certain extent, they make a squeaking sound, which proves that this brake pad is excessively worn and it is time to replace it.

Of course, when abnormal wear occurs, the second situation mentioned above will also occur. After all, other irregular objects will naturally make abnormal noise.

If the abnormal noise generated by the brake only appears for a short time, you don't have to replace the brake pads. If the abnormal noise persists, you have to change it. As mentioned above, when changing the brake pad, we should not be greedy for small and cheap. We should be optimistic about the quality of the brake pad. The brake pad also has its own special performance. For example, LISHIDA brake pad has excellent performance in braking mute. It adopts three-layer silencing pad, fine blanking steel back plate Imported raw materials and original vehicle noise reduction technology solve the noise problem caused by vehicle braking.

If the brake disc has deep grooves and scratches due to the friction of hard objects, it is also necessary to replace the brake disc.

The brake pad continues to make abnormal noise. It should be noted that this is not just a signal of brake pad problems. If ignored, it is likely to threaten driving safety. In addition, Xiaobian believes that he can't deliberately save money for his car. Sometimes he spends more on products with higher quality and better reputation, which is to increase his driving safety virtually.
