Should you change your brake pads?

Brake pad, as the most critical safety part in the automobile braking system, plays a decisive role in the braking effect. It can be said that it is the protector of people and cars.So, is there a potential safety hazard in your car's brake pads? Today, We will take you to pick it up. Generally speaking, it is necessary to consider replacing the brake pads when the vehicle travels to about 40000 to 50000 km. In real life, it is often the case that one kind of brake pad can be used for 50000 or 60000km in one vehicle, but it must be replaced when it is only used for 25000km in another vehicle. When the brake pads are seriously worn, the brake disc indicator light on the instrument panel will turn on to prompt the owner to replace the brake pads, which is the simplest and convenient judgment method. So, what other methods are there? Today, we will tell you about several other specific judgment methods with a "professional" attitude.


The thickness of a new brake pad is generally about 1.5cm. With the continuous friction in use, the thickness will gradually become thinner. Professional technicians suggest that when the thickness of the brake pad is only about 1 / 3 of the original thickness (about 0.5cm), you should increase the self inspection frequency and be ready to replace it at any time. Of course, due to the wheel hub design of individual models, they do not have the conditions for visual inspection, and they need to remove the tire to complete it. We should pay special attention to this.

Tips: The wear and tear of brake pads varies according to different driving environments and driving habits. Therefore, there is no mandatory requirement for the replacement cycle of brake pads. Generally, replacement should be considered when driving about 40000 to 50000 km. When the brake pad is found to be thin by naked eye observation, technicians should be required to check during maintenance, because there will be some errors in naked eye observation, and the caliper of professional maintenance station is more rigorous than naked eye observation.


If your brake gently with the sound like "iron rubbing iron" (the newly installed brake pads sometimes have a similar sound during the running in period, pay attention to the difference), the brake pads must be replaced immediately. Because the limit marks on both sides of the brake pad have directly rubbed the brake disc, it proves that the brake pad has exceeded the limit. In this case, it is necessary to cooperate with the inspection of the brake disc while replacing the brake pad. When this sound occurs, the brake disc is often damaged. At this time, even if the new brake pad is replaced, the sound cannot be eliminated. In serious cases, the brake disc needs to be replaced.

Tips: When you hear this kind of sound when braking, it’s often too late. At this time, the brake disc has been damaged. The price of the brake disc is much higher than that of the brake pad. Therefore, it is recommended that you check the brake pad frequently to avoid damage to the brake disc.


If you feel very hard when braking, it is possible that the brake pads have basically lost friction. At this time, you must replace the brake pads, otherwise it is likely to cause serious accidents, so parents must pay attention.

Tips: This is a relatively abstract method, which may be difficult to grasp by feeling. Therefore, it is important to develop a good self-test habit. In addition, the reduction of braking effect will increase the consumption of brake oil. Therefore, when replacing the brake pads, focus on checking the condition of brake oil.


Well, after so many inspection methods, have you checked your car? Do you need to replace the brake pads? For the sake of safety, drivers who need to replace must do it by themselves or go to relevant stores in time.
