Brake drum noise refers to the abnormal sound generated by friction between the brake shoe and brake drum. When encountering this situation, simply disassemble the brake drum, remove the brake shoe, and clean any foreign objects between them to resolve the issue. If foreign materials are adhered to the brake shoe, use coarse sandpaper to grind them off until separated, then reinstall to solve the problem. If you notice that increased force is required for braking, immediately stop using the vehicle and visit an after-sales service or repair shop as soon as possible to replace the brake shoes. Continued use under such conditions may lead to dangerous situations. Generally, squealing from rear brakes is caused by water ingress, excessively smooth brake pads, or substandard brake pads. First remove the brake disc; if it appears too smooth, sand it with sandpaper or a flat file, and replace the brake pads if necessary.

What to Do After a Car Is Flooded?

After a car is flooded, the first thing to do is to notify the insurance company that covers the vehicle and request an on-site inspection by the insurance company's staff or a third-party representative. The car owner should take photos of the flooded scene with a camera or mobile phone as evidence for the claim. If the vehicle stalls due to water ingress while driving, it is important to stay calm and immediately turn off the ignition. Do not attempt to restart the engine, as this can cause significant damage to the engine and may result in the insurance company denying the claim. Then, disconnect the negative terminal of the battery as soon as possible to prevent short circuits in the vehicle's electrical components due to water exposure. Move the vehicle to a safe location, preferably with the front higher than the rear, to allow water in the exhaust pipe to drain out and avoid damage to the catalytic converter and muffler.

What to Do When Tire Pressure Malfunction Occurs?

Tire pressure malfunction solutions include: 1. Compare the rotation speed of the car's four tires to determine if the tire pressure is normal; 2.

The car dashboard will display a tire pressure warning light to prompt the driver that the car needs immediate repair. Causes include: 1. Very slow tire leakage, which is extremely subtle and cannot be observed with the naked eye; 2. System malfunction, leading to false alarms; 3. After prolonged driving, the tire temperature increases, causing the tire pressure to rise due to thermal expansion.
