It is very important to check the status of the brake pads before long-distance driving, which helps to ensure driving safety. Checking the status of brake pads involves the following aspects:
1. Appearance check: Open the wheel and touch the outer surface of the brake pad with your hand. If the brake pad is cracked, broken or deformed, it should be replaced in time. In addition, attention should also be paid to the degree of wear of the brake pads, and when they wear to the alarm line, replacement should be considered.
2. Wear mark: On most car brake pads, there is a wear mark, which is usually a small hole or notch. When the brake pads wear to the mark, it means that the brake pads need to be replaced.
3. Audio check: After starting the engine, gently press the brake pedal and pay attention to any abnormal sounds. If the brake pads are heavily worn, there may be a harsh rattle or the sound of metal friction. If there are these sounds, the brake pads should be replaced immediately.
4. Brake performance test: Brake performance test in a parking lot or a safe place. Select a distant target, moderate acceleration, hard brake pedal, and observe whether the brake is sensitive, whether there is an abnormal sense of shaking. If the brakes are not sensitive enough, or there is a sense of shaking, it may be a sign of brake pad wear or brake system failure, which needs to be dealt with.
5. Brake fluid check: Open the hood and find the brake fluid storage tank. Check that the brake fluid is within the appropriate level line. If the brake fluid is too low, it may be caused by a brake pipe leak or brake system failure, and should be repaired in time.
6. Brake disc inspection: Touch the surface of the tire rear disc by hand to check the smoothness and smoothness of the brake disc. If the brake disc has significant dents, cracks or wear marks, it may cause brake failure and need to be replaced.
7. Dust and impurities cleaning: Use brushes or jets to remove dust and impurities around the brake pads to ensure that the brake pads work normally.
In short, it is very necessary to check the status of the brake pads before a long drive. Through the appearance inspection, wear marking, audio inspection, brake performance test, brake fluid inspection, brake disc inspection and dust impurity cleaning and other steps, we can find and solve the problem of brake pads in time to ensure driving safety.
