Does a brake pad thickness of 4mm require replacement?

Normally, brake pads need replacement when they are less than 3mm thick. Here are some self-inspection methods for brake pads: 1. Check the thickness: Measure the thickness of the brake pads. A new brake pad is approximately 1.5cm thick, and its wear limit is 0.3cm. When the brake pad thickness is below the wear limit, the metal backing plate will come into contact with the brake disc, producing a metallic friction noise. Therefore, if you hear such noise when braking, you should first check the brake pads. 2. Feel the change in braking force: Pay attention to the change in braking force when applying the brakes. If braking feels more strenuous than usual, or if the brakes are less responsive, or if the brake pedal position feels lower during emergency braking with a longer pedal travel, then the brake pads should be inspected as soon as possible. 3. Observe the warning light: If the brake pad wear warning light on the dashboard comes on, it indicates that the brake pads need to be inspected and replaced.

What is the Principle of Tire Sealant?

Tire sealant works by utilizing fibers and rubber particles or suspended fine rubber particles in the adhesive within the sealant. When a tire loses air, these rubber particles or micro rubber particles precipitate and form clumps to block the air leak. Tire sealant is a mixture containing various high-molecular chemical materials and is widely suitable for rubber tires on electric vehicles, motorcycles, and small to medium-sized cars. It is particularly effective for puncture holes with diameters ranging from 1 to 5mm. The method of using tire sealant is as follows: 1. Shake the sealant well and lift the outer tube; 2. Align the tube opening with the tire valve and tighten it; 3. Tear off the fixing ring on the bottle top and open the switch; 4. You can observe white liquid being injected into the tire through the tube. After inflation, turn the valve counterclockwise to close it.

How many points are deducted for driving in the wrong direction?

Driving in the wrong direction results in a one-time deduction of 12 points. Additional information: According to Article 35 of the "Road Traffic Safety Law of the People's Republic of China": Motor vehicles and non-motor vehicles shall drive on the right side. Motor vehicle driving in the wrong direction is divided into two situations: 1. Driving in the wrong direction on a road section, or not following the prescribed direction on a one-way road: This type of violation constitutes a violation of prohibition signs. Due to factors such as narrow roads and high traffic volume, there are currently 31 one-way roads set up in urban areas to reduce traffic congestion. However, despite the presence of prominent traffic signs at intersections, some drivers still enter one-way roads in the wrong direction. 2. Driving in the wrong direction at an intersection: In China, driving is on the right side. Driving on the left side of a divided road is considered driving in the wrong direction. Motor vehicles driving in the wrong direction pose significant risks. Moreover, if a driver operating a motor vehicle in the wrong direction causes a traffic accident with a vehicle driving in the correct direction, the driver of the wrong-way vehicle bears full responsibility.

The 3M adhesive on the rain visor is difficult to remove. What can be used to clean it?

You can use essential balm to wipe it off, or alternatively use a heat gun or thinner for cleaning. Here is some related information: 1. Rain Visor: A rain visor refers to a car accessory that can be used both in rainy and sunny weather. It is a protruding rain guard made of synthetic resin or engineering plastic material located at the top edge of the car window. The rain visor effectively prevents rain or strong wind from directly blowing into the car, improving ventilation efficiency; it also helps prevent window fogging when driving in the rain with the window open. 2. Wiper: A wiper, also known as a windscreen wiper, is a device used to wipe away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. Due to legal requirements, almost all cars everywhere are equipped with wipers. Rear windows of vehicles such as hatchbacks and SUVs are also equipped with wipers. Apart from cars, other means of transportation, such as trains and trams, are also equipped with wipers. Some engineering machinery, such as cranes, also have wipers.
