In addition to being a simple means of transportation, the car is also a life partner for many people. Many friends like to play with the car after work. Some friends, even if they don't know much about cars, hope to acquire more car knowledge through car use experience and use this knowledge to check their vehicles. In the future, we will bring some vehicle self-inspection tips one after another. Next, let's talk about self-inspection of brake pads.

How to check the brake pads yourself?

Method 1: Look at the thickness
The thickness of a new brake pad is generally about 1.5cm, and the thickness will gradually become thinner as the friction is used. Professional technicians suggest that when the thickness of the brake pads is only about 1/3 of the original thickness (about 0.5cm), the owner should increase the frequency of self-inspection and be ready to replace it at any time. Of course, due to the design of the wheel hub, individual models do not have the conditions for visual inspection and need to remove the tires to complete.

There is a protruding mark on both sides of each brake pad. The thickness of this mark is about two or three millimeters. This is also the limit for the thinnest replacement of the brake disc. If the thickness of the brake pad is parallel to this mark, it must be replaced. Therefore, when the thickness of the brake pads is close to this mark, the owner must observe and prepare at any time, but it is difficult to accurately observe with the naked eye without removing the tires. At present, many models will have the position of the instrument handbrake light when the brake pads are too thin. There are hints, which is more convenient than self-inspection.

Small advice:There is no strict replacement interval for brake pads according to the vehicle environment and driving habits. Generally, replacement is considered when driving about 60,000 kilometers. When the naked eye observation found that the brake pad is thin, it should be in the maintenance of technical personnel to check, because the naked eye observation will have errors, professional maintenance stations through the caliper to observe more rigorous than the naked eye.

If it is a drum brake, it cannot be checked by looking at it. You can use the following two methods to determine whether the brake shoes in the brake drum need to be replaced.

Method 2: Listen to the sound
If the brakes are lightly tapped with the sound of "iron rubbing against the iron" (it may also be caused by the running-in of the brake pads at the beginning of installation), 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, when replacing the brake pads, you must cooperate with the inspection of the brake discs. When this sound occurs, the brake discs are often damaged. (As shown in the figure below) At this time, even if the new brake pads are replaced, the noise cannot be eliminated., The brake disc needs to be replaced in severe cases.

In addition, some poor quality brake pads have hard points, which will also produce abnormal noise. Generally, the abnormal noise generated in this way will disappear after a period of time.

Small advice:When you hear the sound of the brake, it is often too late, and the brake disc will be more or less damaged. The price of brake discs is much higher than that of brake pads, so it is recommended that you check the brake pads frequently to avoid damage to the brake discs.

Method 3: Feel the strength

If the brakes feel very hard, it is possible that the brake pads have basically lost friction. At this time, they must be replaced, otherwise it will cause serious accidents.

Small SuggestionsThis method is relatively abstract and may be difficult to grasp by feeling, so it is very important to develop a good self-inspection habit. In addition, the reduction of the braking effect will lead to an increase in the consumption of brake fluid, so when replacing the brake pads, it is necessary to focus on checking the brake fluid.

purchase replacement suggestion

Many friends are used to buying maintenance materials and going to some repair shops for maintenance after taking off the insurance. For the purchase of brake pads, we still recommend going to 4S store or regular service shop for purchase and replacement, because the types of brake pads in the current market, especially in auto parts city, are varied, it is really difficult to distinguish between true and false, and the prices are also very different, and some products worth 30 to 40 yuan are not qualified at all, therefore, it is suggested that friends who do not have the ability to distinguish authenticity should not buy some unqualified products cheaply to endanger driving safety.

If the brake deviated

Many friends feel that their vehicles have a slight deviation in driving. At this time, they often determine that four-wheel alignment is needed. Special attention needs to be paid here. If everything is normal while the vehicle is driving, and it only deviates when the brakes are heavily stepped on, the brake system must be checked.

The several methods described above can help car owners to conduct daily inspections of brake pads. Of course, the naked eye self-inspection is only a rough judgment. The purpose is to find vehicle problems as early as possible and grasp the current vehicle conditions. Of course, work involving maintenance and replacement It also depends on professional maintenance stations.
