Car brakes may produce noise due to uneven wear during normal use or the presence of foreign objects between the brake disc and brake pads. In such cases, it is necessary to promptly inspect the vehicle to ensure driving safety. The materials used for brake pads include: 1. Asbestos, cellulose, sintered glass; 2. Carbon fiber friction materials; 3. Powder metallurgy friction materials; 4. Semi-metallic friction materials. The function of brakes is to reduce speed or bring the vehicle to a stop. Their working principle involves converting the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and brake drum, as well as between the tires and the ground, thereby slowing down or stopping the vehicle.

Why does the range suddenly drop by one kilometer?

It is normal for a car's range to drop by one kilometer in a few seconds. The car's range is not very accurate, and the display showing a decrease of one kilometer is actually calculated based on recent fuel consumption, which does not necessarily mean the car has traveled exactly one kilometer. The following explains the range: 1. Fuel consumption: The range is calculated by the computer based on the current driving conditions and fuel consumption, indicating how many kilometers the remaining fuel in the tank can still drive. Therefore, as soon as the engine is running, fuel is consumed, and the corresponding range will decrease. The speed of this decrease depends on the driving conditions. 2. Constant changes: No vehicle's range is completely accurate because it is closely related to the average driving speed and instantaneous fuel consumption. It cannot be guaranteed that the vehicle will always drive at the current average speed, so the range is always constantly changing.

Where Are the Front Side Airbags Located?

Front side airbags are typically installed on the outer side of the front seats. Below is relevant information about airbags: 1. Purpose of airbag installation: The goal is to mitigate injuries caused by side impacts by isolating direct contact between the torso and the door panel, effectively protecting the safety of front-seat passengers. Currently, some high-end or high-spec models are equipped with front side airbags. 2. Composition of airbags: Airbags mainly consist of components such as sensors, microprocessors, gas generators, and the airbag itself. Sensors and microprocessors are used to assess crash severity, transmit and send signals; the gas generator, based on signal instructions, initiates ignition, ignites solid fuel, and generates gas to inflate the airbag, causing it to rapidly expand, with a capacity of approximately (50-90) liters. Since their introduction, airbags have saved numerous lives. Studies show that in frontal collisions involving vehicles equipped with airbags, driver mortality rates decreased by 30% in large cars, 11% in midsize cars, and 20% in compact cars.

Where is the cabin air filter located in a Volkswagen Passat?

The cabin air filter in a Volkswagen Passat is located inside the glove compartment in front of the front passenger seat. To replace the cabin air filter, you need to remove the glove compartment in front of the front passenger seat to access and replace the filter. It is generally recommended to replace the filter during spring or autumn, as the air conditioning is used more frequently in summer, making the filter more prone to dirt accumulation. Below are the functions of a car's cabin air filter: 1. Filters the air to ensure that the air entering the cabin is purified. 2. Blocks pollen, dust, and other particulate pollutants in the air. 3. Absorbs odors, carbon compounds, sulfur compounds, and other airborne contaminants. 4.
