Knowledge of brake pad self inspection
As we all know, brake pads are consumables, which will wear out gradually in use. When they are worn to the limit position, they must be replaced. Otherwise, the braking effect will be reduced, and even safety accidents will be caused. Most cars adopt the structure of front disc and rear drum brake. Generally, the wear of front brake shoes is relatively fast, and the service time of rear brake shoes is relatively long. In daily maintenance, we should pay attention to the following aspects:

1. Wear detection
Under normal circumstances, the car needs to check the brake shoes every 5000 km, not only to check the remaining thickness, but also to check the wear status of the brake pads, whether the wear degree on both sides is the same, whether the return is free, etc. if abnormal conditions are found, it must be dealt with immediately.
The brake pad is generally composed of iron lining and friction material. Never replace the shoe until the friction material is worn out. Some cars have alarm function of brake shoes. Once the wear limit is reached, the instrument will give an alarm to prompt the replacement of shoes. When it comes to the limit of use, the brake pads must be replaced. Even if they can be used for a period of time, the braking effect will be greatly reduced, and the driving safety will be affected.

2. Four wheel alignment
The force and speed of the four wheels are different on different roads and curves, and the braking force will also be different, which will lead to the deviation of the wear degree of the brake pads. In the case of car deviation and other problems, it is necessary to make four-wheel alignment for the vehicle in time, so as to avoid tire damage and excessive wear of brake pads on one side of the car.

3. Pay attention to the sound of brake pads
Friends, if you hear the sound of grinding iron sheet when braking normally, it means that the brake pads have worn to the brake disc. You must replace the brake pads and carefully check the damage of the brake disc.

4. Selection of brake pads
When the brake pads need to be replaced, friends must choose the brake pads with good quality. Try to choose the original parts, of course, the quality of the original parts is certainly no problem, but the price is also more expensive. If you replace the brake pads in the repair shop, you need to be very careful, because in order to save costs, some manufacturers do not set alarm lines on the steel back, and all the friction materials are worn out, and there will be no alarm sound, which is quite dangerous. Therefore, within the price range, the famous brand is more reliable, and the service life of the brake pad is also much longer.

5. Precautions after replacement
After changing the brake pads, friends must step on a few brakes to eliminate the gap between the shoes and the brake disc, so as not to cause the first foot not braking and accidents. In addition, after replacing the brake pads, you need to run in about 200 km to achieve good braking effect, so you must drive carefully when you just change the brake pads!
