Reasons for brake system failure: 1. Insufficient brake fluid pressure; 2. Air in the brake system; 3. Excessive free travel of the brake pedal or excessive brake clearance; 4. Poor contact, severe wear, or oil contamination of the brake shoe friction lining; 5. Wear or scoring of the master cylinder, wheel cylinder pistons and cylinder tubes, or aging and damage of the rubber cups. The hazards of brake system failure are: 1. Increased brake pedal travel; 2. Slow braking response; 3. Reduced braking efficiency; 4. Increased braking distance. Solutions for brake system failure: 1. Bleed the brake system; 2. Adjust the pedal free travel, check brake clearance, and disassemble and repair the brakes; 3. Adjust and repair the technical condition of the brakes.

I've been driving for decades and have encountered brake system failures multiple times. The most common issue is when the brake pads wear down to bare metal, making the brakes ineffective when pressed, accompanied by alarming squealing sounds. If the brake fluid leaks or becomes contaminated, the pedal feels spongy and sinks, rendering the hydraulic system useless. Uneven or rusted brake discs cause the car to shake during braking. A faulty ABS sensor can lead to skidding and loss of control on slippery roads. Air entering the brake lines can also make the brakes feel unresponsive. Regular maintenance is crucial—quickly check the brake fluid level monthly to ensure it's within the normal range. If you notice any pedal abnormalities, slow down and pull over immediately. Don't wait until an accident happens to regret neglecting these checks, as such oversights can be life-threatening on the highway.

There are actually many reasons for brake failure, and I pay attention to these details during routine vehicle inspections. Worn-out brake pads are the most common issue, causing a sudden drop in braking power. Leaking or deteriorated brake fluid affects hydraulic performance. Warped or corroded brake discs result in noticeable vibrations when braking. Problems with the ABS system can cause wheel lock-up during emergency braking. Clogged lines or air in the system make the pedal feel spongy. Uneven tire wear can also be an indirect factor. It's recommended to perform regular maintenance—even simple checks like inspecting fluid levels and brake pad thickness can prevent major repairs. If you notice anything unusual while driving, pull over immediately—safety first.

The causes of brake system failure include completely worn brake pads, resulting in a sharp reduction in braking force. Insufficient or contaminated brake fluid causes the pedal to sink. Damaged brake discs lead to pulsation. ABS failure results in malfunction during emergencies. Air entering the system weakens pedal feel. I always check the fluid level and pad thickness every month and address any issues immediately. Stay alert to abnormalities while driving and perform maintenance early to ensure safety.

Do I need maintenance if the car only runs 2000 kilometers a year?

Even if the car only runs 2000 kilometers a year, maintenance is still necessary. Car maintenance cycle: The maintenance cycle of a car is set at the time of production, so the "wrench" indicator will appear after a certain mileage to remind the driver to perform maintenance in time. Typically, the maintenance cycle for a car is every 5,000 to 8,000 kilometers driven, and the original factory setting is usually more than 8,000 kilometers. Regular maintenance items: Engine oil maintenance: Engine oil, also known as lubricating oil, can reduce engine wear and also has the effects of cooling and lubrication. There are three types of engine oil: Full synthetic oil: needs to be replaced every 10,000-12,000 kilometers. If the car is not driven frequently, the oil may emulsify and lose its effectiveness, so it should be replaced after about a year. Semi-synthetic oil: needs to be replaced every 8,000-10,000 kilometers. Mineral oil: needs to be replaced every 5,000 kilometers.

How many bars out of 9 on the car temperature gauge are considered normal?

Generally, exceeding 5 bars out of 9 on the temperature gauge is considered normal. Temperature Gauge: The temperature gauge is used to indicate the temperature of the coolant inside the engine, reflecting whether the engine's cooling system is functioning properly. The gauge ranges from C to H, where C represents 60 degrees Celsius. Once the needle reaches C, it means the coolant temperature has reached 60 degrees; the red H mark indicates 110 degrees Celsius. Consequences of Overheating: If the car's coolant temperature becomes too high, it can lead to poor engine cooling. High temperatures cause components to expand, reducing the clearance between parts. Additionally, high temperatures decrease the viscosity of engine oil, exacerbating wear on components. If not addressed promptly, the engine may suffer severe damage or even complete failure. Conversely, if the engine temperature is too low, it can result in incomplete combustion of the air-fuel mixture, reduced power output, poor lubrication, and increased emissions.

Can You Drive on the Highway Using S Gear All the Time?

It is not recommended to use S gear for prolonged highway driving, as the S gear only delays upshifting without altering other operational aspects, which increases the transmission load, raises the temperature, and accelerates wear in the short term. Additionally, vehicle comfort is poorer in S gear mode, so it is advisable to avoid prolonged use of S gear. Below is relevant information about S gear: 1. Introduction: S stands for "sport," which is the car's sport mode. When shifting to S gear, the transmission can shift freely, but the shifting timing is delayed, keeping the engine at high RPMs for a longer period. This allows the car to operate at low gear and high RPM for an extended time, resulting in greater torque output and acceleration. 2. Benefits of Using S Gear: For cars frequently driven in congested urban areas, engine carbon buildup can be significant. Periodically using S gear appropriately helps remove carbon deposits, improve fuel economy, and extend engine life.

Why is the car always losing water even though the radiator is not broken?

Water loss in the radiator may be caused by damage to the radiator, such as cracks in the cylinder block leading to leaks, which can occur while driving. Inspection items: Check whether the leak occurs when the car is parked or when the engine is hot. Some radiators do not leak when the car is cold and parked, but spray mist when the engine is hot, making it difficult to detect. Inspect the rubber hoses of the radiator and the connections of the water tank's rubber hoses. If the issue persists, apply sealant to all connections, drain all the water, and then add antifreeze to see if the water loss continues. If the water loss persists, replace the cylinder head gasket as it is likely blown. Additionally, check the color and condition of the engine oil to ensure it is normal. Precautions: It is important to note that the car radiator is a critical component for cooling the engine. If the radiator malfunctions and the engine cannot dissipate heat in time, it may cause severe damage to the car. If the radiator runs low on water while driving, it should be checked and refilled promptly.

Is driving with a license expired for three days considered unlicensed driving?

Driving with a license expired for three days is considered unlicensed driving. The introduction to unlicensed driving is as follows: Introduction to unlicensed driving: Driving a motor vehicle on the road without a driver's license is considered unlicensed driving, which has nothing to do with the passenger seat. Driving a motor vehicle without a license on the road will result in a fine, detention of the driver for up to 15 days, and seizure of the motor vehicle. Hazards of unlicensed driving: It poses a serious threat to the safety of life and property of oneself and others. Due to the lack of necessary traffic safety knowledge and driving skills, and failure to comply with traffic rules, traffic accidents may occur, causing harm to oneself and others, and threatening the safety of life and property of oneself and others. It corrupts social morals. Unlicensed drivers disregard the law, ignore traffic rules, and undervalue the life and property safety of others. The existence of such phenomena seriously affects road traffic order and weakens the public's awareness of the law and safety.
