How to Distinguish the Inner and Outer Sides of Brake Pads?

The inner side of the brake pad has a friction block, while the outer side does not. Here is some related information about brake pads: 1. Description: Brake pads are important components in a car's braking system and are also wear-and-tear parts that need regular replacement. 2. Function: When the driver presses the brake pedal, the vacuum booster provides assistance, helping the driver to press the pedal. After pressing the brake pedal, the master cylinder pushes the brake fluid to activate the wheel cylinders, which then push the brake pads to clamp the brake disc. 3. Precautions: Brake pads, brake discs, and brake fluid need to be replaced regularly. Many car owners overlook brake fluid during maintenance. Brake fluid is a liquid that easily absorbs moisture. If the moisture content in the brake fluid is too high, it can lead to reduced braking force and longer stopping distances. When the moisture content in the brake fluid reaches 3%, it should be replaced immediately.

Can Parallel Imported Vehicles Be Licensed?

As long as the import certificates from customs and inspection and quarantine departments are obtained, parallel imported vehicles can theoretically be licensed just like regular imported vehicles. However, if there are compliance issues with national standards for parallel imported vehicles, traffic authorities may impose restrictions during the licensing process. Advantages of parallel imported vehicles: 1. Price advantage: Parallel imported vehicles bypass sales channels such as general distributors, regional distributors, and 4S stores, eliminating many intermediate links. Additionally, parallel import dealers have more freedom in pricing as they are not restricted by manufacturers, resulting in significant price discounts. 2. Model and delivery time advantage: Sometimes, new overseas models are not launched in China due to automakers' strategic plans or domestic certification processes. Parallel imported vehicles naturally excel in this aspect. After being sourced overseas, they are shipped directly to China for sale, saving a considerable amount of waiting time for new models. 3. Richer model configurations: Another advantage of parallel imported vehicles is the ability to purchase overseas models not available in China. Typically, automakers make certain adjustments or modifications to overseas models when importing them to China to align with the local market strategy. Parallel imported vehicles, however, are directly imported from regions like North America and the Middle East, and their configurations may differ from China-specific models.

Is Car Electro-Optic Paint Legal?

It is legal to apply electro-optic paint to cars without large-scale color changes. Here is some relevant information about electro-optic paint: 1. Description: Electro-optic paint is a product that combines paint with weak electricity, along with other materials processed through specific techniques, rather than being a single type of paint. Electro-optic paint can match the original color of the car. A common concern is whether traffic police will intervene if Nightwalker electro-optic paint is applied to a car. According to traffic regulations, vehicle modifications involve changing the car's color, structure, etc. Since electro-optic paint does not alter the car's original color or its electrical circuits, it complies with regulations and is therefore legal, so there's no need to worry. 2. Painting Precautions: When painting, first apply a layer of rust-proof paint, followed by a layer of primer. For cars with dents, these need to be addressed. Minor dents can be filled with putty, while more severe dents require metalworking to restore the original shape.

Why is there abnormal noise during cold start?

Reasons for abnormal noise after cold start: 1. Belt aging: The generator belt ages, and its rubber material is affected by thermal expansion and contraction. When the car is cold, the belt contracts, and daily rotation stretches the belt, which can easily cause the belt to slip during cold start, producing noise. 2. Valve tappet: Due to the valve tappet, during cold start, engine oil is pressurized from the oil pump into the engine oil passage before reaching the valve tappet, which can cause increased noise during cold start. 3. Loss of lubrication: The internal gears of the starter lose lubrication, causing sticking and affecting the timely return of the gears. 4. Carbon brush failure: The carbon brush inside the starter motor malfunctions.

Can the ETC card be turned off when not in use?

ETC's card can be removed when not in use, but be careful not to remove the card during use, otherwise it will cause the ETC to fail to work properly. Benefits of installing ETC: Save time: Avoid the hassle of queuing up; Green and environmentally friendly: Green and low-carbon, vehicles can pass through toll stations without stopping, reducing noise and exhaust emissions and pollution; Save wear and tear: Save costs, reduce the frequency of vehicle starts and brakes, reduce wear and fuel consumption, and users can also enjoy a 5% discount on tolls; Improve efficiency: The efficiency of ETC lanes can theoretically be increased by 2-3 times, making traditional ETC newer, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. ETC working principle: Through the dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna on the ETC lane of the toll station, the computer network technology is used to conduct background settlement processing with the bank, so that vehicles can pass through the highway or bridge toll station without stopping, and can pay the highway or bridge toll.
