What is wheel lock-up?

Here is information about wheel lock-up: 1. The vehicle's braking system has malfunctioned. Solution: In such cases, it is necessary to have the vehicle inspected at a 4S shop to avoid potential hazards while driving. 2. Wheel lock-up refers to a situation where the vehicle's wheels become statically locked when parked, preventing the car from moving normally. 3. If the front wheels lock up while driving, the vehicle may lose steering capability. If the rear wheels lock up, the car may skid sideways, and in severe cases, this could lead to a rollover. 4. Solution for wheel lock-up: Try releasing the brake pedal to restore normal function. Wheel lock-up causes the wheels to lose their ability to resist lateral forces, making the vehicle prone to skidding or losing control, which can be extremely dangerous.

I've been working at an auto repair shop for nearly a decade and frequently deal with cases of wheel lock-up. Simply put, it's when the wheels lock and stop rotating during braking, causing the vehicle to skid out of control. The most common cause is issues with the braking system, such as excessively high or uneven brake fluid pressure, which may result from ABS sensor malfunctions, severely worn brake discs, or blocked brake lines. Another reason is insufficient tire traction, like when braking hard on rainy or snowy days. Many of the cars I've serviced had severely worn brake pads that weren't replaced in time, leading to skidding whenever the brakes were applied—extremely dangerous. I recommend checking brake fluid and brake discs every six months to ensure the ABS functions properly. And don't forget to slow down on slippery roads to prevent accidents.

Last time when I was driving back to my hometown, the wheels suddenly locked up, which was terrifying. It was raining heavily, and I braked too hard, causing the wheels to completely stop and the car to slide straight toward the roadside. Later, I realized it was due to old tires with insufficient grip and improper brake force control. Since then, I've learned my lesson—I always maintain distance and brake gently in rainy weather, and I replace my tires regularly. Simply put, wheel lock-up happens when you brake too hard, causing the wheels to jam and skid, which can easily lead to rollovers or collisions. Causes include lack of brake fluid or system issues, so regular maintenance is essential. Now, I keep emergency tools in my car to safely pull over in case of sudden issues. Safe driving is key—don’t rush.

I'm very interested in cars. Wheel lock-up mainly occurs during hard braking when the braking force exceeds the tire friction, causing the wheels to get stuck and stop rotating. This is common in racing or on slippery surfaces, but it significantly increases danger during normal driving. The ABS system can automatically adjust braking to prevent lock-up by rapidly releasing pressure to allow the wheels to regain rotation. If your car doesn't have ABS, older vehicles rely on cadence braking techniques for manual control. Another factor is when tire pressure is too low or the tread is worn out, reducing grip. It's important to check tire condition before driving. Remember to stay calm during emergency braking to minimize risks.

Which is Better: Built-in or External Tire Pressure Monitoring?

Tire pressure monitoring systems, whether built-in or external, each have their own advantages and disadvantages, and the choice can be made based on the specific needs of your vehicle. 1. Pros and Cons of Built-in Tire Pressure Monitoring Devices: Pros; Installed inside the tire, using a sensor-equipped valve stem to replace the original one, with minimal exposure outside, not protruding beyond the wheel hub. Once installed, it is essentially a permanent solution (can last over 5 years without issues). Cons: Complex installation process, requiring wheel balancing. 2. Pros and Cons of External Tire Pressure Monitoring Devices: Pros: Easy installation. No need to replace the valve stem, no wheel balancing required, and not even needing to inflate or deflate the tire. All the owner might need to do is screw the sensor onto the valve stem. Cons: Not suitable for SUV models with higher tire pressure. Inflating or deflating requires removing and reinstalling the sensor, and external sensors are prone to damage from foreign objects.

How to Control the Steering Wheel of a Car?

Control the steering wheel of a car as follows: 1. After getting in the car, align your body with the steering wheel and keep it straight. Lean your back lightly against the backrest of the seat. Adjust the seat forward or backward to a suitable position according to your height. Fasten the seat belt if the vehicle is equipped with one. 2. Look straight ahead, lightly hold the upper left side of the steering wheel with your left hand and the lower right side with your right hand, with both elbows relaxed and naturally hanging down. The thumbs of both hands should naturally extend and rest on the upper edge of the steering wheel, while the other four fingers should lightly grip from the outside inward. 3. Place your left foot below the clutch pedal and your right foot lightly on the accelerator pedal at about two-thirds of its length. 4. Maintain a relaxed and comfortable driving state and a good driving posture.

What is the speed limit when crossing a narrow bridge with good road conditions?

When crossing a narrow bridge with good road conditions, the speed should be controlled not to exceed 30 kilometers per hour. The following are the relevant regulations: 1. Roads without a center line: urban roads have a speed limit of 30 kilometers per hour, while highways have a speed limit of 40 kilometers per hour. 2. Roads with only one motor vehicle lane in the same direction: urban roads have a speed limit of 50 kilometers per hour, while highways have a speed limit of 70 kilometers per hour. When entering or exiting non-motorized lanes, crossing railway crossings, sharp curves, narrow roads, or narrow bridges, making U-turns, turning, or descending steep slopes, encountering fog, rain, snow, sandstorms, or hail with visibility within 50 meters, driving on icy, snowy, or muddy roads, or towing a malfunctioning motor vehicle, the maximum speed should not exceed 30 kilometers per hour. Among these, tractors, battery-powered vehicles, and wheeled special machinery should not exceed 15 kilometers per hour.

What does the ECOMODE button mean?

Eco-mode refers to the economic driving mode of a car. 'Eco' is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). Eco mode is further divided into active eco driving mode and non-active eco driving mode. When the eco indicator light on the dashboard illuminates, it indicates that the vehicle's economic mode has been activated. Eco mode is categorized into active and non-active types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically adjusts settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active eco mode does not have a dedicated button. When the eco indicator light on the dashboard illuminates, it serves merely as a reminder function. The eco mode automatically evaluates your driving behavior; if your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the eco indicator light. Most cars employ the active eco driving mode, meaning they have their own switch button. Therefore, during daily driving, we can activate the eco mode. However, it is unnecessary to enable eco mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of eco mode but also affect the vehicle's power performance. Additionally, eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, causing the eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, eco mode may also become ineffective. When high torque output is required, such as when climbing hills, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the eco mode will not operate under these conditions either.
