What is the reason for poor braking after replacing brake pads?

Poor braking after replacing brake pads is because the surface of the new brake pads is relatively flat, while the contact surface on the brake disc is very uneven, resulting in a very small contact area between them. Additionally, when braking, the deformation of the brake pads is significant, leading to poor braking performance. Automotive brake pads, also known as automotive brake linings, refer to the friction materials fixed on the rotating brake drum or brake disc of the wheel. The friction linings and friction blocks within them bear external pressure to generate friction, thereby achieving the purpose of vehicle deceleration. Automotive brake pads consist of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate is coated to prevent rust, and the coating process is monitored using an SMT4 oven temperature tracker to ensure the temperature distribution during the coating process meets quality standards.

What are the maintenance items at 15,000 kilometers?

Maintenance at 15,000 kilometers is a routine service: replace engine oil and oil filter, check tire pressure, lights, coolant, etc. More information about car maintenance is as follows: 1. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. 2. Modern car maintenance mainly includes the maintenance scope of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc.

What Causes No Airflow in a BMW Mini's Air Conditioning?

BMW Mini's air conditioning may not blow air due to blower motor failure, clogged cabin air filter, or control system malfunction. Blower Motor Failure: The blower motor is the core component for air conditioning airflow. If it is damaged, the car's air conditioning will definitely not blow air. Blower motor failure may be caused by overheating damage to internal coils or capacitor failure. You can determine if there is a fault by turning the car's air conditioning fan speed and air volume to maximum and listening to the blower motor's sound. If there is a fault, it needs to be repaired at a 4S shop or repair shop. Clogged Cabin Air Filter: Outside air passes through the cabin air filter before entering the car, trapping many airborne particles, which can easily cause clogging. You can remove the cabin air filter to check if it is clean. Control System Malfunction: The car's air conditioning control system may malfunction. The air vent, control switch, or the car's air conditioning computer could be the cause of the problem. It is best to have it checked and repaired at a 4S shop.

Does carrying a child count as overloading?

Carrying one extra child is considered overloading. Here is the relevant information: 1. The traffic regulations regarding "overcrowding" do not specify the height, weight, or age of passengers, but only the "number." Therefore, in a car with a capacity of 5 people, having one extra child (even an infant held in the arms of a parent) is considered overcrowding. 2. Overcrowding does not differentiate between adults and children; as long as they are born, they count as one member. In a five-seat car, even if it's children, only five people can be seated. For example, if there are three adults in a five-seat car and three children, it is considered overcrowding, including those held in arms, because current laws require children to use safety seats.

The Difference Between Diesel Engine Oil and Gasoline Engine Oil

The differences between diesel engine oil and gasoline engine oil are: 1. Different API ratings: Diesel engine oil ratings start with 'C'; Gasoline engine oil ratings start with 'S'. 2. Different combustion flame temperatures: Diesel engine oil combustion flame temperature is 1800 degrees Celsius; Gasoline engine oil combustion flame temperature is 600 degrees Celsius. The functions of engine oil are: 1. To alleviate friction and high temperatures; 2. To reduce gas leakage and prevent external pollutants; 3. To prevent contact between water, air, acidic harmful gases and parts; 4. To buffer the pressure rise at the engine cylinder port; 5. To flush away dirt generated on the working surfaces of parts.

Difference Between Starter and Engine?

Starter and engine differences are as follows: 1. Different energy sources: The starter relies on electricity, converting electrical energy into mechanical energy. The engine relies on fuel, converting internal energy into mechanical energy. 2. Different structures: The starter mainly consists of an electric motor composed of a magnetic field (stator), armature (rotor), and commutator. The engine mainly consists of a cylinder block assembly composed of parts such as the cylinder block, cylinder liner, cylinder head, and cylinder gasket. More related information is as follows: 1. The starter can convert the electrical energy of the battery into mechanical energy, driving the engine flywheel to rotate and enabling the engine to start. 2. Before the engine can operate under its own power, it must rely on external force to rotate. The process by which the engine transitions from a stationary state to self-sustained operation with the help of external force is called engine starting.
