This is due to worn brake pads. When this occurs, new brake pads should be replaced. Brake pads are consumable parts in the braking system that require periodic replacement. As the vehicle's mileage increases, the brake pads will continuously wear down and need replacement once they reach a certain level of wear. Below is an introduction to related content: Introduction: The braking system is a crucial system in a vehicle, directly related to driving stability and safety. Main Components: The main components of the braking system include the vacuum booster pump, master cylinder, slave cylinder, brake pads, and brake discs. The vacuum booster pump provides assistance, making it easier for the driver to press the brake pedal. When the brake pedal is pressed, the master cylinder pushes the slave cylinder via brake fluid. At this point, the slave cylinder can press the brake pads against the brake disc, slowing the vehicle down. The brake disc is also a wear item that requires periodic replacement. As the vehicle's mileage increases, the brake disc will continuously wear down and need replacement once it reaches a certain level of wear. Precautions: The brake fluid in the braking system also needs regular replacement. Brake fluid is a liquid that easily absorbs moisture. If the brake fluid's water content becomes too high, it can lead to reduced braking force and longer braking distances. Therefore, it is essential to regularly replace the brake fluid during vehicle use. When the brake fluid's water content reaches 3%, it should be replaced immediately.

When to Replace Spark Plugs for Audi A6L?

Audi A6L spark plug replacement cycle: Under normal maintenance conditions, replacement is recommended after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is advisable to follow the user manual. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Spark plug working principle: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block through the cylinder head. The insulator primarily serves to isolate the metal shell and the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the central electrode, it ionizes the medium between the central electrode and the ground electrode, generating a spark to ignite the air-fuel mixture in the cylinder.

What type of engine oil should be used for the Changan CS35?

For the maintenance of the Changan CS35, SL-grade 5W-30 viscosity engine oil is recommended, with an oil quantity of 3.4L. After filling, the oil level on the dipstick should be between the MIN and MAX marks, neither below the MIN mark nor above the MAX mark. Below is an introduction to engine oil: 1. 5W30 refers to the SAE standard viscosity value, indicating that this oil is a multi-grade oil. 2. W stands for WINTER, and the number before W represents the flow performance at low temperatures. The smaller the number, the better the starting performance at low temperatures. The number after W represents the stability of the oil at high temperatures. The larger the number, the better the stability at high temperatures. 3. The smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature.

What is the standard distance for low beam cutoff line to the ground?

10 meters from the wall, the lower edge of the cutoff line is 0.875 meters from the ground. Relevant information about low beam headlights is as follows: Combination methods of low beam headlights: There are mainly two types of combination switch methods for car low beam headlights. One is the lever type, located on the left lever of the steering wheel; the other is the knob type, located below the left air vent on the center console. When to use low beam headlights: Low beam headlights must be turned on when driving in areas without street lights at night, or during dusk when it's getting dark or at dawn when light is just appearing; if encountering heavy fog, snow, or heavy rain that obstructs visibility, low beam headlights must be turned on even during the day; on some roads where there are lighting facilities but the brightness is insufficient, low beam headlights should also be turned on.

Should You Use the Internal or External Air Circulation in a Car?

Whether to use internal or external air circulation depends on the situation. Here is the relevant information: 1. Internal air circulation in a car: The main purpose of internal circulation is to promptly and effectively prevent external dust and harmful gases from entering the vehicle. When driving through areas with smoke, dust, unpleasant odors, or in heavy traffic, it blocks harmful exhaust emissions from the vehicle ahead. Another function is to maintain warmth inside the car. 2. External air circulation in a car: This allows you to breathe fresh air from outside. During long drives on highways, if the air inside the car becomes stuffy and uncomfortable and you cannot open the windows, you should use the external circulation to let in some fresh air. In winter, if the warm air feels too hot, you can turn off the fan and switch to external circulation, which maintains the interior temperature while providing fresh air, making you feel more comfortable.
