How Long Will New Brake Pads Squeak?

How long new brake pads will squeak mainly depends on the type of brake pads, as different types require different break-in periods. Brake Pad Lifespan: Under normal driving conditions, the front brake pads of most vehicles last between 30,000 to 50,000 kilometers, while the rear brake pads can last between 120,000 to 150,000 kilometers. The exact replacement time depends on the wear condition. The mileage specified by manufacturers may vary for different vehicle models. Brake Pad Replacement Tips: When replacing brake pads, it is advisable to choose products from reputable manufacturers. Typically, brake pads produced by reputable manufacturers have clear packaging prints, including license numbers, specified friction coefficients, and execution standards. The packaging box should also contain a certificate of compliance, production batch number, and production date. It is recommended to have new brake pads installed by professionals at a specialized repair shop to avoid errors that could lead to potential safety hazards. Checking Brake Pad Condition: When inspecting brake pads, it is also important to check the wear of the brake discs or drums to ensure sufficient contact area with the brake pads for improved braking performance.

Can a Motorcycle Stored for 6 Years Be Registered?

A motorcycle stored for 6 years cannot be registered anymore. Since July 2019, the Chinese government has implemented new regulations on exhaust emissions, stipulating that motorcycles failing to meet the National IV emission standard must cease production, sales, and registration. Motorcycles from 6 years ago only meet the National III emission standard, which falls short of the National IV requirement, making them ineligible for registration. According to the Road Traffic Safety Law, all motor vehicles, including motorcycles, must be registered and licensed with the traffic management authorities within three months from the date of purchase. If this period is exceeded, late fees will be imposed. Additionally, the motorcycle's invoice remains valid until the vehicle is scrapped, which is typically after 15 years. Therefore, to avoid late fees, owners should promptly register their motorcycles at the local vehicle management office. Unregistered motorcycles are not permitted to operate on public roads; otherwise, the rider may face fines, penalty points, or vehicle impoundment. As per the Road Traffic Safety Law of the People's Republic of China, motor vehicles driven on roads without license plates, inspection stickers, insurance stickers, or without carrying the vehicle registration certificate and driver's license will be detained by traffic police. The owner will be required to provide the necessary documents or complete the registration process, along with paying a corresponding fine. Documents Required for Motorcycle Registration: Original and photocopy of the motorcycle owner's ID card; Purchase invoice (the name on the invoice must match the ID card); Vehicle qualification certificate and engine/chassis number imprint; Original proof of vehicle purchase tax and compulsory third-party liability insurance; The motorcycle must be brought to the traffic police department for inspection and photography.

Should the AC be turned on when using the car's air conditioning?

To use the cold air function, you must press the AC button; otherwise, the air conditioning system will only blow air at normal temperature. This is because the AC button controls the compressor, a key component of the cooling system. When using the cold air function, try to avoid prolonged use. Keeping the air conditioning at a low temperature for too long can create a significant temperature difference between the inside and outside of the car and increase fuel consumption. The car's air conditioning cooling system consists of a compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. These components are connected by copper (or aluminum) pipes and high-pressure rubber hoses to form a sealed system. When the cooling system operates, the refrigerant circulates through this sealed system in different states, achieving the purpose of lowering the temperature of the air around the evaporator. Compression process: The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature, high-pressure gas, which is then discharged from the compressor. Heat dissipation process: The high-temperature, high-pressure superheated refrigerant gas enters the condenser. Due to the drop in pressure and temperature, the refrigerant gas condenses into a liquid, releasing a large amount of heat. Throttling process: The higher-temperature and higher-pressure refrigerant liquid passes through the expansion device, where its volume increases, and its pressure and temperature drop sharply, exiting the expansion device as a mist (fine droplets). Heat absorption process: The mist-like refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into a gas. During this process, it absorbs a large amount of heat from the surroundings, and the low-temperature, low-pressure refrigerant vapor then re-enters the compressor. Precautions for using the air conditioning in the car: Do not set the air conditioning temperature too low. A large temperature difference between the inside and outside of the car can easily cause the driver to catch a cold, and excessively low temperatures may also increase the risk of arthritis for passengers. Control the direction of the air vents. Based on the principle that cold air sinks and hot air rises, when using the air conditioning, set the vents to face upward when cooling and downward when heating. Do not turn on the air conditioning immediately after the car has been exposed to the sun. After prolonged exposure, the temperature inside the car will be very high. First, open the windows to ventilate and allow the hot air to escape before turning on the air conditioning.

Should Volkswagen Bora use 5W30 or 40 engine oil?

Volkswagen Bora originally uses SM5W-40 semi-synthetic engine oil. The replacement capacity is 4L, and the replacement cycle is 10,000 kilometers. For later maintenance and oil changes, you can choose brands such as Mobil, Shell, Castrol, and Total. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand low temperatures of -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, the better it maintains viscosity at high temperatures, which can also be understood as better lubrication performance under high temperatures. The method for changing the engine oil in a Volkswagen Bora is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine for 30 seconds to allow the oil in the main oil passage to drain; Use a special wrench to remove the oil filter; Apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add new engine oil through the oil filler cap on the engine valve cover, usually filling about three-quarters of a 4L bottle; Start the engine and let it run for 5 minutes, then check for oil leaks around the drain plug and oil filter. If any leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick to check if the oil level is within the standard range.
