Shaking when braking is caused by: uneven wear of the brake discs. The solution is to replace the brake discs or resurface them. Methods for maintaining brake discs include: 1. Develop good driving habits; 2. Avoid emergency braking; 3. Regularly inspect brake pads and discs; 4. Check the thickness of the friction material; 5. Have a professional inspect the brake shoes; 6. Use original equipment manufacturer (OEM) brake pads and discs when replacing. The function of brakes is to reduce speed or bring the vehicle to a stop. The working principle involves converting the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and drums, as well as between the tires and the road surface, thereby slowing down or stopping the car.

I encountered a similar situation when repairing my car before. The main reason for the car body shaking when braking is likely due to uneven brake disc surfaces, which can become deformed from prolonged use or frequent braking at high temperatures, causing rhythmic pulsations. Additionally, uneven wear of the brake pads or contamination with grease can also lead to inconsistent braking performance and vibrations. Loose wheel hub bearings can also have an impact, potentially amplifying vibrations when turning or braking. If the shock absorbers in the suspension system have aged and lack sufficient support, the overall stability of the car body will decrease. I remember a friend's car had this issue once, and ignoring it led to longer braking distances, almost causing an accident. So, I recommend going to a professional repair shop as soon as possible to check the brake discs. Resurfacing or replacing them can usually solve the problem—don't skimp on safety to save money.

What are the symptoms of a damaged car air conditioning thermostat switch?

The symptoms of a damaged car air conditioning thermostat switch are: 1. When the engine coolant reaches the set temperature and the electric fan should start, the electric fan does not work; 2. When the engine coolant has not reached the set temperature and the electric fan should not start, the electric fan turns on and continues to operate until the battery is drained. The functions of the air conditioning system include: 1. Controlling the temperature inside the cabin; 2. Removing humidity from the air; 3. Drawing in fresh air to provide ventilation; 4. Filtering the air to remove dust and pollen. The maintenance methods for the air conditioning system are: 1. Clean the air conditioning vents promptly; 2. Maintain the air conditioning condenser in a timely manner; 3. Clean or replace the air conditioning filter element promptly.

What Causes Paint Peeling?

There are many reasons for paint peeling, which ultimately come down to poor maintenance. For new cars, the paint surface generally has no issues and does not naturally peel unless there is a scrape or collision that is not repaired promptly. However, it also depends on the area. For example, if there is a minor scratch on the bumper and it doesn't affect the appearance, it may indeed be left untreated, as most bumpers are made of non-metallic materials and do not pose a rust risk. More relevant information is as follows: Color Difference: There are nuances in paint repair. Many people notice that the repainted areas on their cars have a slight color difference compared to the original factory paint. This is hard to avoid because the refinishing process at later stages rarely matches the level of the original manufacturer. Durability: If the paint is applied at a repair shop with relatively simple equipment, the durability of the paint surface may be poorer, and natural peeling may occur more easily.

What is the allowable error for electronic truck scales?

Electronic truck scales have measurement errors that are separately inspected at multiple weighing points. For example, a truck scale with a maximum capacity of 100t, a verification scale interval number of 3000, a verification scale interval of 20kg, and a minimum weighing capacity of 20kg must not exceed the allowable error values at 10 tons, 50 tons, 80 tons, and 3000 grams. The scale is considered qualified only when all these points pass inspection. Additional relevant information is as follows: Inspection Items: When inspecting truck scales at a nationally authorized metrological verification institution, there are many inspection items, such as the visual inspection of the truck scale, electromagnetic interference resistance testing, metrological mark verification, and auxiliary function checks. Metrological Standards: Truck scales belong to weighing instruments of accuracy class. Marked as Class III, also known as Class 3 scales.

What are the potential damages caused by car atomization disinfection?

Complex operation, excessively long disinfection time, severe interior pollution leading to suboptimal effectiveness, and potential adverse effects of steam on the vehicle's electronic systems are some concerns. Below is relevant information: Chemical disinfection: This method primarily involves spraying and wiping car components with disinfectants to eliminate pathogens through chemical reactions. This sterilization approach is simple to operate and achieves thorough pathogen elimination. Common chemical disinfectants on the market include peracetic acid and 84 disinfectant. While this method provides thorough disinfection, it leaves behind odors in the cabin post-treatment, requiring ventilation for a period. Ozone disinfection: Ozone disinfection machines utilize specialized automotive equipment that rapidly generates large quantities of ozone for disinfection purposes. Ozone serves as a highly efficient broad-spectrum rapid sterilizer capable of eliminating various pathogens and microorganisms. When reaching specified concentrations, disinfection and sterilization can be completed swiftly.
