Brake modifications can pass the annual inspection, but it is necessary to report to the vehicle management office in advance. The following are relevant introductions about brakes: 1. Definition: A mechanical braking device that can slow down the speed of a vehicle, also known as a decelerator. The car brake pedal is located under the steering wheel. Pressing the brake pedal causes the brake lever linkage to be pressurized and transmitted to the brake pads on the brake drum, which then clamp the brake disc, slowing down or stopping the vehicle. 2. Function of brakes: The principle of braking is to convert the kinetic energy of the vehicle into heat energy for dissipation. The kinetic energy comes from the power provided by the engine, which requires fuel combustion to do work. In other words, every time you press the brake, it means a little bit of gasoline is wasted.

I remember when I first learned about car modifications, I tried upgrading the braking system by installing larger brake discs and high-performance calipers, mainly for better stability and safety when braking at high speeds. Before the annual inspection last year, I was a bit nervous, worried it might be illegal, so I went to a repair shop to ask. The mechanic said that the inspection mainly checks braking performance, such as whether the braking distance and braking force meet standards, and if there are any fluid leaks or loose components. As long as the modified parts are of high quality and installed professionally without affecting original functions like ABS, they should pass. My car actually performed better during the inspection and passed in one go. However, from a safety perspective, it’s strongly advised not to use cheap, low-quality parts. Before modifying, check local regulations and go to a reputable shop to avoid small gains leading to big losses. Brakes are a matter of life and death—one oversight could lead to an accident.

How to Operate a Tiptronic Transmission?

Operating method of a tiptronic transmission: Under normal circumstances, you can simply drive in D (Drive) mode. When encountering long and steep uphill or downhill slopes, you can switch to L (Low) or M (Manual) mode to manually downshift. If you encounter a red light lasting several dozen seconds, it is recommended to shift to N (Neutral) mode. During normal driving, you can freely switch between D mode and manual mode without needing to stop. Most of the time, a tiptronic transmission operates in automatic mode—its essence remains an automatic transmission. Therefore, the purpose of the manual mode in a tiptronic transmission is to compensate for the shortcomings of automatic mode in certain situations. For example, when climbing a steep slope or overtaking, the acceleration in automatic mode may be slower, and the vehicle's torque may not meet the requirements. In such cases, switching to manual mode allows for quick overtaking or low-speed climbing.

How to adjust the headlights of the Buick GL8?

Buick GL8 headlight adjustment method: First, open the hood. There is a vertical screw directly above the headlight, which can be turned to adjust the height of the headlight. When adjusting the headlights, do not use a wall. Drive the car onto a flat road, adjust the low beam to a 30-meter distance with the two points overlapping, and adjust the high beam to be parallel to the ground. Using a wall is for adjusting the two high beam points to be parallel. The Buick GL8 is an MPV model under the Buick brand. The dimensions of this car are 5219mm in length, 1878mm in width, and 1776mm in height. The Buick GL8 is equipped with a 2.0-liter turbocharged engine across all models, with a maximum power of 191 kW and a maximum torque of 350 Nm.

Should the Clutch Be Depressed When Starting the Car?

Starting the car with the clutch depressed is primarily to prevent the car from suddenly lurching forward during startup, which could lead to accidents. This is especially crucial when starting on uphill or downhill slopes, where failing to depress the clutch may cause the car to roll, potentially resulting in accidents. Therefore, the primary reason for depressing the clutch when starting a manual transmission car is safety. Additionally, depressing the clutch during startup protects the engine. Without depressing the clutch, the engine would operate under excessive load, causing damage over time. While occasional occurrences may not cause immediate issues, prolonged neglect can lead to gradual engine problems.

What is the most suitable position for adjusting the steering wheel?

The most suitable position for adjusting the steering wheel is: the top edge of the steering wheel should be roughly at the same height as the driver's shoulders, while maintaining a comfortable legroom in the front and back, as well as a comfortable distance between the driver and the steering wheel. The steering wheel is a wheel-shaped device used to control the direction of vehicles such as cars, ships, and airplanes. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and transmit it to the steering shaft. If the steering wheel is viewed as a clock face, the correct hand position is to place the left hand between the 9 and 10 o'clock positions and the right hand between the 3 and 4 o'clock positions. This posture provides better body support in the event of a collision. If only four fingers are used to grip the steering wheel with the thumb extended and resting on it, when the wheel hits a rock or a high curb, the front wheel may suddenly turn to one side, causing the steering wheel to rotate rapidly, which could potentially break the thumb.

What Causes Car Shaking Upon Startup?

Reasons for car shaking upon startup: 1. Poor fuel quality: Inferior fuel has poor volatility, especially during cold winter temperatures. During cold starts, when the engine block temperature is low, fuel atomization becomes difficult, resulting in insufficient mixing of fuel and air in the combustion chamber. This leads to difficult startups and severe body shaking. 2. Carbon buildup in engine valves and intake manifold: Carbon deposits can absorb certain amounts of fuel, causing the electronic control unit to make incorrect judgments. 3. Spark plugs: During cold starts when both fuel and lubricant temperatures are low, the engine requires more fuel to generate sufficient power. This causes the electrode gap in spark plugs to gradually widen, reducing ignition energy and worsening fuel atomization, consequently causing body shaking.

Which Lights Should Be Turned On When Driving in Foggy Weather?

In foggy conditions with low visibility, drivers' sight is severely obstructed, making it difficult to spot obstacles and increasing safety hazards. Therefore, drivers should turn on fog lights and avoid using high beams. When encountering oncoming vehicles in fog, drivers should honk in advance to alert the other vehicle, choose wide road sections for low-speed passing, and immediately stop to yield if there is any danger. When driving at night without streetlights, poor lighting, or in low-visibility conditions such as fog, rain, snow, dust, or hail, drivers should turn on headlights, clearance lights, and tail lights, but must not use high beams when following another vehicle closely in the same direction. Vehicles should also turn on fog lights and hazard warning flashers in foggy conditions. When following another car in fog, pay attention to the leading vehicle's movements, maintain a safe distance, and avoid driving in the center of the road or crossing lane markings.
