There are several reasons for soft brakes in heavy-loaded trucks: air in the system; excessive free play; poor-quality brake fluid with a low boiling point, causing bubbles during braking; and poor sealing of the master cylinder or wheel cylinders, leading to pressure loss. Below are some tips for driving near large trucks: 1. Avoid truck blind spots: Trucks have large blind spots, especially on the right side. Often, trucks drive in the middle of the road, and if slow vehicles block the fast lane, drivers may attempt to overtake from the truck's right side, which is highly prone to accidents. 2. Dangers of truck turns: When a truck turns, there is a specific term called 'inner wheel difference,' referring to the difference between the front and rear wheels on the turning side. If a car stays in this area, the truck driver may not see it at all. Keep a safe distance.

What is the maximum wading depth of the Volvo XC90?

According to official information, the maximum wading depth of the Volvo XC90 is 45 cm. It uses 275/45R20 tires, has a body height of 1776 mm, a curb weight of 2015-2071 kg, and is a five-door, five-seat SUV. The maximum wading depth refers to the deepest water a vehicle can safely pass through. Generally, sedans have a maximum wading depth of no more than 30 cm, while SUVs can handle slightly deeper water, though it's best not to exceed 50 cm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30 cm, the Audi A4 has 32 cm, the Volkswagen Sagitar has 30 cm, the Land Rover Range Rover has 90 cm, the Jeep Compass has 48 cm, and the Highlander has 45 cm. SUVs clearly outperform sedans in wading depth. Generally, depending on the water depth and the vehicle's specifications, drivers should take different measures as follows: If the water reaches the exhaust pipe height, it is still safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel it. As long as the engine is not turned off in the water, no backflow will occur. If the water reaches the door frame height, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom, risking short circuits and damage to critical electrical parts, which may prevent the car from starting. If the water reaches the air intake height, it is extremely dangerous. Driving directly into such conditions may cause the engine to stall immediately, leading to permanent damage or rendering the engine unusable.

Does Crystal Coating Damage Car Paint?

If it is a new car, crystal coating will not damage the paint surface; however, for a car that has been used for a period of time, applying crystal coating can cause damage to the paint because it requires polishing first. For a new car, crystal coating only requires deep cleaning of the paint surface, followed by mirror restoration, then degreasing treatment, and finally applying the crystal coating directly. The diamond crystals in car crystal coating contain anti-static agents, making the paint surface less likely to attract dust and preventing traffic film. The diamond crystals have a structure similar to that of diamonds, which can enhance light refraction, making the car surface brighter and the paint more radiant, with a brightness level of over 95%.

What is the difference between front fog lights and low beams?

Difference between fog lights and low beams: In terms of beam angle, brightness, and light penetration, fog lights are superior to low beams. Fog lights generally refer to automotive fog lights. Automotive fog lights are installed at the front and rear of the vehicle to illuminate the road and provide safety warnings during rainy or foggy weather, enhancing visibility for the driver and other traffic participants. Low beams are designed for short-distance illumination, with a wide coverage range (160°) but a short projection distance, and the focus cannot be adjusted. The projection distance of low beams is approximately 30-40 meters. Function and usage time of fog lights: Fog lights have strong penetration. In heavy fog, they can cut through dense fog, allowing drivers to see the road ahead clearly. However, fog lights should only be used in heavy fog conditions. Their power is much higher than that of low beams, and their beam angle, brightness, and penetration are also significantly higher. While they are highly effective in heavy fog, their intense penetration can be glaring. Using fog lights in normal weather conditions can cause significant interference for drivers of vehicles ahead or behind, easily leading to accidents. When to use low beams: When encountering other vehicles or pedestrians, switch to low beams. When unfamiliar with the road and needing to read road signs or other markers, high beams can be used but should be quickly switched back to low beams. When overtaking another vehicle, the left turn signal should be activated in advance, and high beams or the horn should be used to alert the vehicle ahead to yield. When driving in dimly lit areas without streetlights, low beams must be turned on. How to turn on fog lights: Press the front and rear fog light buttons on the car to activate them. How to turn on low beams: On the left side of the steering wheel, there is a set of light combination switches. At night, rotating the combination switch forward one notch turns on the dashboard lights, and rotating another notch turns on the low beams.
