Abnormal noises in car brakes may be caused by rust on the brake discs or brake pads. Principle of Car Brakes: The working principle of brakes mainly comes from friction, utilizing the friction between the brake pads and the brake discs (drums) as well as between the tires and the ground to convert the kinetic energy of the moving vehicle into heat energy through friction, thereby stopping the car. A good and efficient braking system must provide stable, sufficient, and controllable braking force, and have excellent hydraulic transmission and heat dissipation capabilities to ensure that the force applied by the driver on the brake pedal is fully and effectively transmitted to the master cylinder and each slave cylinder, while avoiding hydraulic failure and brake fade caused by high temperatures. The braking systems on cars are divided into two main types: disc brakes and drum brakes. However, apart from cost advantages, the efficiency of drum brakes is far inferior to that of disc brakes. Location of Car Brakes: The car brake pedal is located under the steering wheel. In an automatic car, there are only two pedals: the left foot brake and the right foot accelerator pedal. In a manual car, there are three pedals, arranged from left to right: the clutch pedal, brake pedal, and accelerator pedal.

Is a Tire Pressure of 2.8 Normal?

Car tire pressure of 2.8 is not normal, as reaching 2.8 bar may cause a tire blowout. According to the international GBT2978-2008 standard, the standard tire pressure for car tires should be maintained between 2.3-2.5 bar. Based on the standard tire pressure principle, it is also acceptable to appropriately reduce the pressure by 0.2 bar during summer. Additional details are as follows: 1. Low Tire Pressure: If the tire pressure is too low, it will increase the contact area between the tire and the road surface while driving. During high-speed driving, encountering road protrusions may lead to a blowout. 2. High Tire Pressure: If the tire pressure is too high, it will reduce driving comfort, decrease the contact area between the tire and the road surface, and also impair the vehicle's handling performance.

Where is the grounding generally connected in a car?

Any wire connected to the metal body of the car can serve as a grounding point. Here are the relevant details: 1. The main grounding wire between the battery and the car body: One end of this wire is connected to the battery terminal, and the other end is connected to the car frame, sometimes through a master switch. Some cars do not have this master switch. Since battery terminals are prone to corrosion and sulfation, this grounding wire often has poor contact with the battery. Poor grounding is like adding a large resistor to the car's electrical circuit, causing issues ranging from difficulty starting the engine and dim lights to complete failure to start the engine, leaving the entire car without power. 2. The grounding wire between the engine and the car body or battery: The engine is not directly connected to the metal body of the car; it is mounted on the car body via rubber pads to reduce vibration. Poor engine grounding can prevent the starter from starting, the generator from generating electricity, or the generated electricity from being delivered. It can also cause sensors to fail to detect accurate signals, spark plugs to produce weak sparks, and directly affect the engine's performance.

How many tons can the Jianghuai Junling V6 carry?

The load capacity of the Jianghuai Junling V6 is 1.8 tons. When using this vehicle, it is essential not to overload it. More relevant information is as follows: 1. Load: If overloaded, it will impose unnecessary stress on the frame, engine, transmission system, and braking system, which will affect the vehicle's service life and may also compromise driving safety. 2. Braking distance: Overloading can extend the vehicle's braking distance, and in critical moments, this extended braking distance can lead to severe traffic accidents. 3. Load: Overloading can also increase the stress on the transmission system, affecting its service life. 4. Metal fatigue: Long-term overloading can lead to metal fatigue in the frame, and in severe cases, it may even cause the frame to crack or deform.

Is It Serious If Water Gets Into the Vehicle's Exhaust Pipe?

Water in the exhaust pipe can affect the car. Water entering the exhaust pipe can lead to serious consequences such as water entering the engine. If only the exhaust pipe has water, it is important to remove the accumulated water as soon as possible to prevent impurities in the water from clogging the catalytic converter or damaging the oxygen sensor. To drain the water, simply press the accelerator to increase the exhaust pressure and expel the water. Here are some precautions for driving in rainy weather: 1. Slow down: Regardless of the road width or condition, always drive slowly in the rain and be prepared to take emergency measures. Visibility is low in rainy weather, and the braking distance of vehicles is extended, so it is important to slow down in advance to allow enough time and space to handle any situation safely. 2. Maintain a safe distance: Rainy conditions reduce visibility, so it is crucial to keep a safe distance from other vehicles, especially large trucks. Large trucks can block your view and create water splashes that may interfere with your driving. Additionally, they may pass through deep water that smaller vehicles cannot. 3. Use fog lights: Make full use of fog lights to enhance driving safety in the rain. If necessary, turn on the hazard warning lights to alert vehicles behind you to your movements. 4. Do not restart the engine if it stalls: In heavy rain or storms, some areas may flood quickly. If you must drive through water, do so at a steady speed in a low gear. If the engine stalls, do not attempt to restart it immediately, as this could cause severe engine damage. Instead, contact a professional repair service to inspect the vehicle before restarting.

What is the size of the Leiling wiper?

Leiling wiper size is 26 inches for the main wiper and 14 inches for the secondary wiper. Here is some information about wipers: 1. Introduction: The wiper, also known as the windshield wiper, is a device used to wipe off raindrops and dust attached to the vehicle's windshield to improve the driver's visibility and enhance driving safety. 2. Function: The wiper is used to remove raindrops and dust from the vehicle's windshield to improve the driver's visibility and increase driving safety. There are generally vacuum wipers, electric wipers, and wipers with electronic control units. The disadvantage of vacuum wipers is the unstable speed of the wiper blade. When the engine vacuum decreases (such as when climbing a hill), the wiper blade stops swinging, causing the driver's vision to blur.

What kind of glue should be used to firmly reattach a fallen ETC device?

If the ETC device falls off, you can use 3M double-sided tape to reattach it after reactivation. Here are some precautions for installing ETC: 1. Installation height: Pay attention to the installation height, which should be no less than 1.2 meters and no more than 2.5 meters. 2. Installation angle: The installation angle N should be between 30° and 90°, which is the angle between the surface of the electronic tag and the horizontal plane. 3. Avoid obstruction: When installing, avoid the black areas on the windshield and do not install it in a position that blocks the solar battery. 4. Do not remove it casually after installation: Avoid ETC failure after removal.
