How Does Disc Brake Work?

Disc brake works by installing a disc that rotates synchronously with the wheel on the hub, and mounting a caliper on the fork and frame. The brake pads inside the caliper then clamp the disc to achieve braking. Here is some related information about disc brakes: 1. Classification: Disc brakes are sometimes called rotor brakes, divided into ordinary disc brakes and ventilated disc brakes. Ventilated disc brakes have many round ventilation holes drilled on the disc surface, or ventilation slots cut on the end face of the disc, or rectangular ventilation holes prefabricated. Ventilated disc brakes utilize airflow for better cooling and heating effects compared to ordinary disc brakes. 2. Advantages: The main advantages of disc brakes are rapid braking at high speeds, better heat dissipation than drum brakes, consistent braking performance, and ease of installing advanced electronic devices like ABS.

Can a small nail puncture on the tire sidewall be repaired?

Whether a small nail puncture on the tire sidewall can be directly repaired depends on whether the damaged area exceeds 6 centimeters. If it does not exceed, it can be repaired; if it exceeds, the tire needs to be replaced. The following is relevant information about car tires: 1. Importance of tires: Well-maintained vehicle tires can ensure good ride comfort and smooth driving, guarantee excellent adhesion between the wheels and the road surface, and improve the vehicle's traction, braking, and off-road capability. 2. Hazards of underinflated tires: Low tire pressure can increase tire body deformation, easily causing cracks on the sidewalls and generating flexing movements, leading to excessive heat, accelerating rubber aging, fatigue of the cord layer, and breaking of the cords. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders.

What are the vehicle emission standards for annual inspections?

Vehicle emission standards are the National IV standard. The following are the harmful substances and hazards of vehicle emissions: Harmful substances in vehicle emissions: Vehicle emissions contain hundreds of different compounds, including pollutants such as solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, and sulfur oxides. Hazards of vehicle emissions: While directly harming human health, vehicle emissions also have a profound impact on the environment of human life. Sulfur dioxide in the emissions has a strong irritating odor and, when reaching a certain concentration, can easily lead to "acid rain," causing soil and water sources to acidify and affecting the growth of crops and forests.

What does ECO mean in an automatic transmission car?

ECO in an automatic transmission car refers to the economic driving mode function. ECO is an English abbreviation formed by the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The 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 begins adjusting 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 dashboard ECO indicator light illuminates, it serves merely as a reminder function. The ECO system 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 a dedicated switch button. Therefore, during daily driving, we can generally 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 but also negatively impact 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, in N/P gear, or in manual mode, the ECO mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the ECO mode will not function in such scenarios.

What Safety Measures Should Be Taken for Mortgaged Vehicles?

Mortgaged vehicles can be secured by replacing all lock cylinders. Below is relevant information about mortgaged vehicles: 1. Classification: Mortgaged vehicles are divided into fully paid mortgaged vehicles and non-fully paid mortgaged vehicles. Fully paid mortgaged vehicles are legal and can be traded, while non-fully paid mortgaged vehicles are illegal and cannot be traded. 2. Definition: When vehicle owners or property owners urgently need cash, they provide real estate as collateral to financial institutions for loans. There are two sources of mortgaged vehicles: one is directly from state-recognized investment companies, guarantee companies, or pawnshops, and the other is from private financial companies as loan collateral.

How to Prevent Fogging on Car Windows?

Here are several methods to prevent fogging on car windows: 1. Wipe with a towel: Using a towel to wipe off the fog is the fastest way to remove it, but you need to stop the car first. Wiping the fog while driving can distract your attention and affect driving safety. 2. Open windows for convection: Utilize the convection method by opening the windows slightly. Fogging occurs due to the temperature difference between the inside and outside of the car. Opening a window gap allows the incoming air while driving to lower the interior temperature, causing the fog to dissipate naturally. 3. Use the air conditioning defogging function: Most cars come with a defogging feature. Simply turn on the window defogging function to use it.
