Why is there air in the brake system again a few days after bleeding?

Brake bleeding not being completely effective can be attributed to the following reasons: When the master cylinder returns but the wheel cylinder does not, a certain vacuum is created in the pipeline, allowing air to enter if the wheel cylinder rubber seal is not tight. Below is some related information about brakes: 1. Introduction: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other means of transport, or machinery. The general principle of braking involves fixing a wheel or disc on the high-speed shaft of the machine and installing corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. The brake device, also known as a decelerator, is a mechanical braking device that can slow down the speed. 2. Purpose: To reduce speed or bring the vehicle to a stop. The principle of braking is to convert the kinetic energy of the vehicle into heat energy, which is then dissipated. The kinetic energy comes from the power provided by the engine, which requires fuel combustion to generate.

What Causes Slow Cooling in Car Air Conditioning?

Slow cooling in car air conditioning may be caused by the following reasons: 1. Insufficient refrigerant due to low levels: The primary cause of refrigerant shortage is usually minor leaks in the system. If there is insufficient refrigerant in the air conditioning system, the amount of refrigerant sprayed into the evaporator from the expansion valve will also decrease. Consequently, the heat absorbed during evaporation in the evaporator will diminish, leading to reduced cooling capacity. 2. Moisture infiltration in the air conditioning refrigeration system: A component called the dryer (or receiver-drier) in the refrigeration system is responsible for absorbing moisture from the refrigerant to prevent excessive moisture from reducing cooling efficiency. However, when the desiccant in the dryer becomes saturated, it can no longer filter out moisture. As the refrigerant passes through the expansion valve's throttle orifice, the drop in pressure and temperature causes the moisture in the refrigerant to freeze, obstructing the flow of refrigerant, increasing resistance, or even completely blocking it. 3. Reduced heat dissipation capacity of the condenser: Due to varying operating environments, the condenser located in front of the car engine can become covered with oil, dirt, or debris, reducing its heat dissipation capability. Additionally, issues with the cooling fan, such as a loose drive belt, decreased fan speed, or high-speed fan problems, can also impair the condenser's heat dissipation. The solution is to clean the condenser surface with a soft brush and promptly address any fan malfunctions.

What Kind of Water Should Be Added to the Engine Radiator?

The liquid added to a car's engine radiator is antifreeze coolant, also known as antifreeze or antifreeze coolant. Its primary function is to cool the engine during operation, ensuring the engine works at normal temperatures and preventing overheating or freezing in winter. Precautions for Adding Coolant: Avoid adding water to the antifreeze. Adding water to antifreeze raises its freezing point and reduces its cooling efficiency. Moreover, tap water contains impurities such as scale, which can cause sedimentation and impair the performance of the car's cooling system. When replacing antifreeze, it is essential to flush the cooling system internally to remove any residual scale. Antifreeze contains descaling agents, and if scale is not cleaned promptly, it can affect the antifreeze's performance when added. Do not add antifreeze immediately after turning off the engine when it is still hot. Opening the cap at this time can cause the antifreeze to splash out and potentially cause injury. If you must add coolant urgently, wait for the engine to cool down. Remember to wrap the cap with a damp cloth and open it slowly.

What are the differences between Continental CC5 and CC6?

Here are the differences between Continental CC5 and CC6: 1. Tire tread pattern: The tread design is unique, with innovations in both connotation and technology surpassing the CC5. 2. Noise reduction: The CC6 incorporates two noise-reducing combinations in its tread design: sound-absorbing chambers and frequency-modulated noise reducers. 3. Cost-effectiveness: The CC6 is an upgraded version of the CC5, offering improvements in wear resistance, handling performance, comfort, and durability compared to the CC5, while maintaining the same price for better value. Below is additional information about Continental tires: 1. Continental tires are renowned for their all-weather safety and reliability, low noise, and strong self-cleaning properties. They feature extremely high instantaneous overload capacity, responsive handling and cornering stability, excellent braking performance on both dry and wet surfaces, superior water drainage protection, and are the only road tires globally approved for driving at 360 km/h, earning a Guinness World Record. 2. SSR run-flat tires allow vehicles to continue driving up to 80 km at 80 km/h even when the tire is completely depressurized. 3. Continental's tread design and compact outer shoulder effectively enhance shoulder hardness, maximize road contact, and significantly improve cornering stability. Optimized contour technology also notably increases tire mileage. 4. Flat and narrow belt layers prevent tread slippage during tire rotation, greatly improving wear resistance. The new silica compound further enhances driving stability and odometer accuracy, keeping the tire softer and more flexible for a longer period.

What Kind of Motorcycle is Called a 'Jiche'?

In Taiwanese society, 'Jiche' refers to what is commonly known as 'small-displacement motorcycles' in mainland China, indicating a difference in terminology between Taiwanese compatriots and mainlanders. It does not encompass all motorcycles, as large-displacement motorcycles in Taiwan are still referred to as 'motorcycles.' Motorcycles, in terms of maximum speed, weight, and power output, fall under the category of motor vehicles. Based on displacement, they are classified into 50cc light motorcycles, 50-250cc small motorcycles, 250-600cc medium motorcycles, and those exceeding 600cc are called heavy motorcycles. By model type, they can also be categorized into street bikes, sports bikes, rally bikes, off-road bikes, etc. The diameter of the cylinder is referred to as the bore. The piston moves reciprocally within the cylinder; the distance traveled by the piston from the top dead center (TDC) to the bottom dead center (BDC) is called the piston stroke, or simply stroke. Working principle: The intake valve opens, the piston moves downward, and the mixture of gasoline and air is drawn into the cylinder. At this point, both the intake and exhaust valves close, the piston moves upward, compressing the mixture. When the mixture is compressed to its minimum, the spark plug ignites it, and the pressure generated by combustion pushes the piston downward, rotating the crankshaft. When the piston reaches the lowest point, the exhaust valve opens to expel the exhaust gases, and the piston continues to move upward to expel any remaining exhaust gases.

How to Adjust Steering When Reversing into a Parking Space?

The method for adjusting steering when reversing into a parking space is as follows: when entering from the left, turn the steering wheel to the left in advance. If the left side is narrow, delay turning the steering wheel to the left. When entering from the right, delay turning the steering wheel to the right. If the left side is narrow, turn the steering wheel to the right in advance. The details are as follows: 1. When the car body is tilted to the right, the rearview mirror shows a "left wide, right narrow" position relationship. At this time, turn the steering wheel to the left by 1/4 of a turn, and straighten the direction when the car body is aligned. 2. When the car body is tilted to the left, the rearview mirror shows a "right wide, left narrow" position relationship. At this time, turn the steering wheel to the right by 1/4 of a turn, and straighten the direction when the car body is aligned. 3. When the car body is parallel to the garage but the entire car is tilted to the left, if not adjusted, it is easy to press against the left front corner of the garage when exiting to the left. Therefore, you can first turn the steering wheel to the right by 1/4 of a turn, observe that the front wheels do not easily press the line, and when the distance on the right side is about right, turn the steering wheel to the left by 1/4 of a turn. When the car body is parallel to the garage again, straighten the direction. If the entire car is tilted to the right, the operation principle is the same, but the adjustment direction is opposite.
