Why do cars have front disc and rear drum brakes?

This is mainly due to the consistency and stability of braking performance. Below is the relevant information: 1. Consistency of braking performance: Drum brakes have greater braking performance, while disc brakes have higher stability in braking performance. The consistency of braking performance mainly refers to the degree to which braking performance is maintained. This involves the issue of thermal fade, as general brake drums or discs are made of cast iron, and the friction pads are made of several materials such as semi-metallic and asbestos-free. During normal braking, the temperature of the friction pads is generally around 200 degrees. When braking frequently, the temperature of the friction pads will rise, causing the friction coefficient of the friction pads to decrease, meaning the braking performance will decline. This is the so-called thermal fade phenomenon. 2. Stability of braking performance: When the friction coefficient of the friction pads decreases due to rising temperatures, the intelligent performance factor of various types of brakes will also decrease. The most affected here is the servo type, followed by duo-servo, leading-trailing, and disc. Therefore, the least affected is the disc brake, making the stability of disc brake performance the best.

What Needs to Be Replaced for a BMW at 20,000 Kilometers?

BMW at 20,000 kilometers requires the following replacements: 1. Engine oil and oil filter: BMW uses fully synthetic oil, which should be replaced every 10,000 kilometers on average. Therefore, at 20,000 kilometers, the engine oil and oil filter need to be replaced. 2. Air filter: The manufacturer requires replacing the air filter once every two oil changes, so at the 20,000-kilometer maintenance, the air filter needs to be replaced. 3. Cabin air filter: The manufacturer requires replacing the cabin air filter once every two oil changes, so at the 20,000-kilometer maintenance, the cabin air filter needs to be replaced. Of course, it can also be replaced in time according to the actual usage environment. 4. Fuel filter: The manufacturer requires replacing the fuel filter once every two oil changes, so at the 20,000-kilometer maintenance, the fuel filter needs to be replaced. 5. Spark plugs: For B-series and S-series engines, the manufacturer requires replacing the spark plugs every 20,000 kilometers. For M and N series, they should be replaced every 40,000 kilometers. 6. Brake fluid: After 20,000 kilometers, if the brake fluid has been in use for more than two years, it also needs to be replaced.

Difference Between Car Radiator and Condenser?

The differences between a car condenser and radiator are as follows: 1. Different connecting pipes: The car condenser is connected with aluminum pipes, while the radiator is connected with rubber hoses. 2. Different attached devices: The car condenser is equipped with an aluminum cylindrical dryer nearby, whereas the radiator has a water temperature sensor underneath. 3. Different thickness: The car condenser is about 15mm thick, while the radiator is approximately 30mm thick.

The Function of Turbine Oil System

The functions of the turbine oil system include lubrication and supply. The specific details are as follows: 1. Lubrication: It supplies oil to the bearings of the unit to lubricate and cool them. In the sliding bearings of the turbine, the turbine oil fills the gap between the journal and the bearing bush, forming a fluid lubrication film, thereby achieving lubrication. 2. Supply: It provides stable and sufficient pressure oil to the regulation system and protection devices, ensuring their normal operation. It also supplies lubricating oil to various transmission mechanisms. Based on the functions of the turbine oil system, the oil system is generally divided into two parts: the lubricating oil system and the regulating (protection) oil system.

What are the consequences of not wearing a seat belt?

The following are the consequences of not wearing a seat belt: 1. Consequences for pregnant women and passengers holding infants: For pregnant women or passengers holding infants who genuinely cannot wear seat belts, traffic police will enforce the law humanely during roadside checks, issuing warnings before letting them pass. 2. Consequences for rear-seat passengers not wearing seat belts: Drivers will also be penalized if rear-seat passengers do not wear seat belts, which many drivers find unfair. 3. Inability to protect passengers in the event of a traffic accident: If seat belts are properly fastened during a traffic accident, the injuries sustained by vehicle occupants will be significantly less severe compared to not wearing seat belts.

Can You Not Remove the Carpet When a Car Gets Flooded?

You need to remove the carpet when a car gets flooded. After flooding, the car carpet absorbs a large amount of water. If not removed promptly, the accumulated water will cause a foul odor that lingers and fails to evaporate, significantly impacting the driving and riding experience. The interior and carpets of a flooded vehicle absorb substantial moisture—squeezing the inner sponge will release a lot of water. Since the interior is mostly made of fabric or leather, prolonged soaking in water leads to mold growth and unpleasant odors. Hence, the distinct smell of a flooded car is easily recognizable. Therefore, it's essential to remove these soaked carpets as soon as possible, clean them thoroughly, and dry them under direct sunlight to eliminate moisture.
