What to Do When Car Brakes Make Abnormal Noises?

If your car brakes are making abnormal noises, the solution can be determined based on the specific situation. Here is an analysis of the possible causes of brake noise: 1. Brake Pad Issues: Abnormal noises from brake pads are usually caused by wear and tear scraping the disc, in which case simply replacing the brake pads will suffice. Another cause could be aging of the brake pad surface or sharp edges, which can be resolved by grinding the surface and edges of the brake pads. 2. Brake Disc Deformation: If the noise is caused by the brake disc wobbling from side to side and scraping against the brake pads while driving, grinding the brake disc to repair the deformation will fix the issue. Alternatively, if the noise is due to rust on the brake disc surface, the sound will usually disappear on its own after a few minutes of driving as the rust is worn off during braking.

Are Cars Afraid of Sun Exposure?

Exposing a car to intense sunlight in summer can cause certain damages. Here is expanded information about the hazards of sun exposure to cars: 1. Increase of harmful gases inside the car: Although sun exposure can eliminate odors in the car, such as formaldehyde and other harmful gases, excessive exposure can produce a large amount of these gases in a short period, which are difficult to dissipate. Therefore, remember to ventilate the car while it is exposed to the sun. 2. Increased safety hazards: Items like compressed gas containers and lithium battery products are prone to explode or catch fire under high temperatures, along with commonly used items like lighters for men, moisturizing sprays for women, cooling sprays frequently used in summer, and power banks. It is best to store these items in the glove box or other areas of the car that avoid direct sunlight, or preferably not keep them in the car at all. 3. Risk of spontaneous combustion: Exposing a vehicle to intense sunlight may lead to spontaneous combustion.

What are the raw materials for producing new energy batteries?

Production of new energy batteries mainly uses lithium iron phosphate and ternary lithium as raw materials. Currently, most new energy vehicles on the market use ternary lithium batteries. The following is a related introduction to ternary lithium batteries: 1. Introduction to ternary lithium batteries: Ternary lithium batteries are lithium-ion batteries that use nickel-cobalt-aluminum or nickel-cobalt-manganese materials in a certain proportion as the cathode. 2. Advantages of ternary lithium batteries: Ternary materials are composite oxides of several multi-metal materials. They can fully utilize the advantages of metals, and the battery capacity is relatively high, so they are widely used in passenger vehicles.

What is the maximum allowable tire pressure difference among four tires?

The tire pressure difference among four tires should not exceed 0.1 bar. It is normal for the four tires to have slightly different pressures within a 0.1 bar range. However, exceeding this threshold does not necessarily require immediate adjustment, as factors like tire pressure monitoring system errors or varying vehicle loads may cause temporary pressure variations. According to the international GBT2978-2008 standard requirements, recommended tire pressures are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. Tire pressure reset procedure: First, turn on the ignition switch. Press and hold the tire pressure monitoring reset button until you hear a "beep" sound, then release. The system will store the current normal pressure data, automatically clear previous records, and finally the dashboard warning light will turn off, indicating successful reset completion.

How to Purchase Compulsory Insurance for Vehicles?

Compulsory insurance for vehicles must be purchased from an insurance company. Here is some extended information about compulsory insurance: 1. Definition: Compulsory insurance refers to the Compulsory Traffic Accident Liability Insurance for Motor Vehicles. It means that when an insured vehicle is involved in a traffic accident, the insurance company will provide monetary compensation to the victims for personal injuries and economic losses caused by the accident. It is important to note that the beneficiaries of this insurance do not include the occupants of the vehicle or the insured person. 2. Precautions: Compulsory insurance is a service contract between the vehicle owner and the insurance company. If it expires for even one day, the contract is terminated and no longer has legal effect. After expiration, it is necessary to renew the insurance as soon as possible. As long as the lapse in coverage does not exceed three months, you can still enjoy discounts.

Can a Car Still Be Driven After Being Flooded?

If a vehicle has been flooded, it is recommended not to drive or use it. Here is extended information about the hazards of flood-damaged cars: 1. Electronic Control Systems Inside the Car: Rainwater mixed with contaminants is highly corrosive and can affect the functionality of electrical components, especially in the long term. Most cars are equipped with electronic control systems (e.g., engine ECU, ABS system, SRS system, GPS navigation, etc.). If these systems are exposed to water, it can cause short circuits in the ECU's internal IC circuit board and rust on connector terminals, gradually leading to corrosion of metal parts. This can result in poor contact or even short circuits and burnout in the circuits. 2. Engine: The connecting rod in the engine may deform, shortening the piston stroke and preventing proper compression of gases. Piston rings may lose elasticity or fail to seal, causing gas leakage. Compressed gases may escape into the crankcase. Intake and exhaust valves may not seal properly when closed, leading to compressed gas leakage into the intake and exhaust manifolds.
