People's lives are inseparable from cars, and now there are more and more people buying cars. The performance of the car is naturally very important, but the key moments have to be able to stay in the car. The brake system is very critical in the car safety system. If there is a problem with the brake system, the consequences are very serious. Brake pads are a key component in the brake system. After a period of use, the brake pads will have some problems that affect the braking effect. Then, how should the brake pads be tested for replacement? Next, we will introduce how to detect the brake pads. In general, the life of a pair of brake pads is between 18,000 km and 60,000 km. The life of the specific brake pads and the driver's driving habits, the driving environment, the quality of the brake pads, the weight of the car, etc. are all related. There are many factors affecting the brake pads. The difference in the life of the brake pads is very different. If we know how to detect the brake pads, this will provide more protection for our driving safety. How to detect brake pads 1. Look at the brake pad condition from the braking force If you step on the brake pad, it will be deeper than before, and you may not be able to brake the car properly. It is likely that the brake pad is worn and thinned. At this time, it is necessary to make a more detailed inspection of the brake pads and replace them if necessary to avoid affecting the braking effect. 2. Pay attention to the brake sound When braking, you can pay attention to the sound of the brakes. If you hear the squeaking sound of the iron shovel when you brake, it means that the wear level of the brake lining has reached the limit, and it will be replaced at this time. At the same time, the brake disc will also be affected, so check it together. 3. In addition to the above two methods, you can check whether the need to replace by observing the thickness of the brake pad. This method is more intuitive. As the number of brakes increases, the thickness of the brake pads will become thinner and thinner, and the braking effect will also decrease. Generally, the thickness of the newly purchased brake pad is about 1.5cm. If the thickness of the brake pad is found to be only one-third of the original, it must be processed and replaced in time. In addition, there are some precautions in the daily inspection and maintenance of the brake pads. 1. Check the brake pads every 5,000 km under normal driving conditions, not only check the remaining thickness, but also check the wear state of the brake pads. The degree of wear on both sides is the same, whether the return position is free or not, and it is necessary to find abnormal conditions. Handle immediately. 2. Replace the brake pads provided by the original spare parts when replacing, so as to minimize the braking effect between the brake pads and the brake discs. 3. To replace the brake pads, special tools are needed to prevent the brake caliper guide screws from bending. 4. Maintain good driving habits, concentrate on driving, and decide whether to step on the brakes according to the situation. The brake pads play a key role in the braking effect, so it is very important to detect, maintain and replace the brake pads. It is worth mentioning that the wear of the brake pads is caused by the improper braking habits of the owners, especially some novices. It is necessary to know more about when to brake.
