Do Brake Pads Need to Be Replaced at 40,000 Kilometers?

What is the difference between one and a half turns and 90 degrees?

One and a half turns represent a 180-degree rotation of the steering wheel, while 90 degrees refers to a 90-degree rotation. Steering wheel operation follows these principles: 1. Centering Principle: The amount turned should be returned proportionally—quick turns require quick returns, and slow turns require slow returns. Use the car emblem as a reference to check if the wheel is centered. 2. Safety Principle: At high speeds, steering reactions should be quick with minimal adjustments—fine-tuning with one finger or half a finger. 3. Cornering Principle: The steering wheel should match the curve—quick turns for wide curves and slow turns for tight curves. 4. Correction Principle: If steering too early, adjust less and slower; if too late, adjust more and faster. Oversteer requires small corrections, while understeer needs quick compensation.

What Causes Severe Jerking After an Oil Change?

The reasons for severe jerking after an oil change are as follows: 1. Engine oil: The oil does not meet the standard or too much oil has been added. 2. Break-in period: After the break-in period of a new car, the engine noise may increase, and fuel consumption decreases. 3. Viscosity: The new oil has higher viscosity, leading to greater mechanical resistance and increased cylinder pressure. The functions of engine oil are as follows: 1. Lubrication: During engine operation, the friction between components is rapid and intense. A sufficiently thick oil film is needed between the piston and cylinder to separate the two components and reduce friction. 2. Cooling: The engine generates a lot of heat during operation, and the oil carries some of this heat back to the oil pan for dissipation. 3. Cleaning: Engine parts can produce oil sludge, carbon deposits, worn metal particles, and inhaled dust, which can easily form carbon buildup.

What is the wading depth of the BYD Han?

Generally, it should not exceed half the height of the wheel hub, which is still within a safe range. Daily use requires careful inspection. Below is relevant information on the impact of wading on a vehicle: 1. Brake failure: Residual water after wading can prevent the brake discs and pads from fully engaging, leading to a loss of braking power. 2. Causes chassis rust: Rainwater on roads is often dirty, containing various debris like fallen leaves. When a vehicle wades through water, these debris can easily stick to gaps in the chassis, leading to rust over time. 3. Damages headlights: Headlights are essential equipment for driving in rainy, foggy, or nighttime conditions, and their performance directly affects driving safety. If the headlight cover's seal is not tight, water can easily enter during wading, causing fog inside the headlight and reducing light transmission. 4. Causes short circuits: The engine compartment contains numerous wiring harnesses and circuits. When a vehicle wades through water, the connectors of these harnesses may get wet, potentially leading to short circuits.

Will Insurance Companies Compensate for Flood-Damaged Vehicles?

If you did not purchase the waterlogging insurance, compensation will not be provided for vehicles submerged in water if the insurance was purchased before the comprehensive reform of auto insurance was officially implemented. However, for auto insurance purchased after the implementation of the comprehensive reform, compensation will be provided as long as the vehicle damage insurance is included. Below is an introduction to the classification of flood-damaged vehicles: 1. Flood Level 1: The water just reaches the vehicle chassis, and the vehicle floor may become damp, but the likelihood of significant water ingress is low, and the impact on the vehicle's electrical equipment is minimal. 2. Flood Level 2: The water level reaches half of the wheels. Due to the incomplete sealing of the vehicle, water will begin to enter the interior. For lower cars, the water level inside may affect the adjustment motors of the seats and electrical components such as heating and ventilation. 3. Flood Level 3: The water almost completely submerges the tires. At this point, the water level inside the vehicle will completely submerge the seat cushions and the central armrest area, while also affecting a large number of electrical components.

What is the reason for the car air conditioner losing pressure after a few days of use without leakage during pressure testing?

If the car air conditioner does not leak during pressure testing but loses pressure after a few days of use, it is necessary to determine whether there is a lack of refrigerant. Another possible cause could be leakage from the charging valve. Below is an introduction to car air conditioning: 1. Introduction to car air conditioning: The car air conditioning system, abbreviated as car AC, is used to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to optimal conditions. It provides a comfortable environment for passengers, reduces travel fatigue, and creates good working conditions for the driver, playing an important role in ensuring safe driving. 2. Components of car air conditioning: Generally includes refrigeration devices, heating devices, and ventilation devices. This combined system makes full use of the limited space inside the car, with a simple structure and easy operation, making it a popular modern car air conditioning system internationally.
