Methods to determine if the primer is exposed include: 1. Visual inspection—the color of the primer is opposite to that of the car paint, resulting in a noticeable color difference; 2. Run a fingernail over the scratch—if it feels slightly rough and indented, it indicates damage to the primer; 3. Check if the scratched area has rusted. The main functions of the primer are: to enhance the smoothness of the car's surface, making the color paint appear fuller and adhere better when applied. Methods for car paint maintenance include: 1. Promptly remove dust from the car body to minimize static electricity attracting dust; 2. Rinse off rain stains with clean water after rain; 3. When wiping, follow the direction of water flow from top to bottom.

What does the curb weight of a car mean?

Car curb weight refers to the empty weight of the vehicle when it leaves the factory. The curb weight includes the weight of various tools, parts, and fluids added to the vehicle, measured without any passengers. Curb weight is not the same as the total weight of the vehicle. Below are some related explanations: 1. The total weight of a vehicle includes the curb weight, the weight of the driver and passengers, and the weight of any luggage carried in the vehicle. These combined weights make up the total weight of the vehicle. If the vehicle is equipped with additional accessories, their weight must also be included. 2. Generally speaking, for the same model, the more advanced the production process, the more optimized the design, and the higher the level of industrialization, the lower the curb weight will be. Of course, this is on the premise that the vehicle's various performance aspects, especially safety, are not compromised. The specific reason is that the use of high-strength steel and metal materials requires sufficiently advanced manufacturing technology. The more high-strength steel is used, the lower the total weight of the vehicle.

Can Rear Drum Brakes Modified to Disc Brakes Pass Annual Inspection?

Generally, changing drum brakes to disc brakes does not affect the annual vehicle inspection as long as it is registered with the vehicle management office. As long as the braking system functions properly during the inspection, it can pass smoothly. Typically, modifications like changing the paint color, full-body decals, body modifications, or license plate damage are the main concerns that might fail the inspection. Below is related content: 1. Reasons not recommended to change drum brakes to disc brakes: The conversion requires replacing many components, which can be costly. Additionally, the braking system is crucial, and modifications might affect the vehicle's warranty. 2. Differences between drum brakes and disc brakes: Disc brakes, also known as hydraulic brakes or oil brakes, use friction between the brake pads and the disc to slow down. Drum brakes, a traditional braking method, use friction between the brake shoes and the drum. Most vehicles on the market use disc brakes for the front wheels and drum brakes for the rear, commonly referred to as the 'front disc rear drum' configuration.

What is the function of power windows?

Power windows refer to windows that automatically raise and lower the glass using power. They are operated by the driver or passengers through a switch that activates the window lift motor circuit. The motor generates power, which is transmitted through a series of mechanical transmissions to raise or lower the window glass as needed. More details are as follows: 1. The power window system mainly consists of a lift control switch, motor, lift mechanism, and relay. The motor is typically a bidirectional permanent magnet motor, which rotates forward or backward by controlling the current direction to achieve window movement. 2. There is a window lock switch on the window; once turned off, the power window switch will no longer function. 3. Power windows also include a thermal switch, which primarily controls the current to provide protection and prevent motor overload. Additionally, if the window glass cannot move freely due to other reasons, the thermal switch will automatically cut off the circuit. 4. There is also a safety feature where some rear windows cannot be fully lowered to the bottom to prevent children from sticking their heads or hands out of the window, thereby avoiding potential traffic accidents.
