Brake discs are made of iron. They are one of the essential components in a vehicle, closely related to safety. However, they are often overlooked during maintenance, leading to inspections only when problems arise. Types of Brake Discs: 1. Solid Brake Discs: These are simple metal discs used for braking. They are inexpensive but have poor heat dissipation, resulting in relatively weaker thermal braking performance. 2. Standard Vented Discs: An improvement over solid discs, these offer better heat dissipation and more stable braking performance. Most modern cars use this type. 3. Drilled Brake Discs: These provide superior cooling, shorter braking distances, and more stable braking performance, typically used in high-end vehicles. 4. Slotted Brake Discs: These can expel dust and debris from the disc surface. In wet conditions, they also help drain rainwater, preventing excessive water from affecting braking performance. 5. Ceramic Composite Brake Discs: Made from a mixture of carbon fiber, graphite, and silicon, these offer superior braking performance in both hot and cold conditions, along with a longer lifespan. They are generally used in luxury cars or high-performance sports cars.

What does the green license plate on cars represent?

It is a special license plate for new energy vehicles. On April 18, 2016, China officially introduced special license plates for new energy vehicles, primarily to effectively identify these vehicles. Small new energy vehicles have gradually green license plates, while large new energy vehicles have yellow and green plates. The first batch of new energy license plates was put into trial use on December 1, 2016. Five cities launched pilot programs, namely Shanghai, Nanjing, Wuxi, Jinan, and Shenzhen, issuing new energy vehicle license plates in sequence. On December 28, 2017, Beijing officially began using the special license plates for new energy vehicles. The new energy license plate features a unique symbol, with green as the main color, representing electricity and new energy. Compared to traditional vehicle license plates, this plate has an additional digit, making it easy to distinguish from regular plates. The production process has been improved, adopting pollution-free manufacturing methods.

Reasons for the Electronic Parking Brake System Warning Light to Illuminate?

The reasons for the electronic parking brake system warning light to illuminate are: 1. ABS function failure; 2. Severe brake pad wear, leading to failure; 3. Brake fluid does not meet requirements. The principle of the electronic parking brake is: When parking, after the driver operates the electronic button of the electronic parking brake system, the electronic control unit will control the motors integrated in the left and right brake calipers to act, driving the brake caliper pistons to move and generate mechanical clamping force to complete parking. The method of using the electronic parking brake is: 1. Activate the electronic parking brake by stepping on the brake pedal and pulling up the electronic parking brake switch until the indicator light on the dashboard lights up, and the handbrake switch indicator light also lights up; 2. Deactivate the electronic parking brake by pressing the electronic parking brake switch while stepping on the brake, and the indicator lights on the dashboard and switch will turn off.

What Causes Transmission Whining?

Reasons for transmission whining: Excessive meshing clearance in the transmission. When the meshing clearance is too large, the driving gear impacts the driven gear during rotation, producing a knocking sound. This noise typically worsens as the transmission temperature rises. Gear noise can also result from damaged gear tooth surfaces, which creates an uneven sound. The louder the throttle, the more pronounced the noise becomes, and in severe cases, vibration in the transmission may be felt. Below is relevant information about transmission fluid: 1. Inspection method: The method for checking automatic transmission fluid differs from engine oil. Engine oil is checked when the engine is cold, whereas transmission fluid should be preheated to approximately 50°C before inspection. 2. Replacement interval: Automatic transmission fluid replacement follows a specific cycle. Due to the extremely precise internal control mechanisms and small fitting clearances in automatic transmissions, most manufacturers recommend changing the transmission fluid every two years or 40,000 to 60,000 kilometers.

What are the symptoms of a faulty canister purge valve?

The symptoms of a faulty canister purge valve are as follows: 1. The fuel nozzle shuts off prematurely during refueling, or there is a gas ejection when opening the fuel tank cap; 2. Fuel vapor or dripping fuel is observed at the canister's atmospheric vent; or upon removing the canister, it is found to be filled with gasoline. 3. Poor acceleration, jerking movements, and unstable idle speed that fluctuates up and down; 4. Engine stalling and failure to start, accompanied by unusual noises while driving. 5. When disconnecting the oil tank's pipe, one can feel intermittent suction at the canister's connection port, with a frequency of about two to three times per second; if there is no suction, it indicates that the canister purge valve is stuck in the closed position. 6. Unplugging the canister purge valve's connector: if the suction stops, the valve is functioning normally; if suction persists, it means the valve is stuck in the open position.
