How to Replace the Brake Pads of an Electronic Parking Brake?

Replacing the brake pads of an electronic parking brake involves the following steps: 1. Use a jack to lift the front part of the car; 2. Remove the tire using tools; 3. Unscrew the caliper bolts, take out the damaged brake pads, and replace them. The electronic parking brake is an electronically controlled mechanical parking brake system that integrates the temporary braking function during driving with the long-term braking function after parking. The working principle of the electronic parking brake is to achieve parking through the friction clamping between the brake shoes and the brake drum or between the friction pads and the brake disc, with the control method being replaced by electronic buttons and motors instead of the original manual operation and mechanical linkage.

What are the reasons for the decrease in antifreeze?

The reasons for the decrease in antifreeze are: 1. Leakage; 2. Antifreeze entering the cylinder. The method for replacing antifreeze is: 1. Open the car hood after the engine has cooled down; 2. Open the antifreeze reservoir cap; 3. Lift the vehicle and open the radiator drain plug, drain the old antifreeze, and then reinstall the drain plug; 4. Lower the vehicle and pour new antifreeze into the antifreeze reservoir. The full name of antifreeze is antifreeze coolant, which is a type of coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It contains: calcium chloride, methanol, ethanol, ethylene glycol, glycerin, etc.

What Kind of Oil is Best for Turbocharged Engines?

For turbocharged engines, it is essential to use full synthetic oil, and the oil viscosity should match the viscosity recommended in the engine's user manual. Currently, most turbocharged engines recommend an oil viscosity of 30. Therefore, you can use full synthetic oils such as 0W30 or 5W30. It is recommended to use 0W for better low-temperature fluidity, allowing the oil to be pumped to lubrication points more quickly during cold starts, thereby reducing cold-start wear. Over 90% of engine wear occurs during cold starts. The following four types of vehicles are recommended to use full synthetic oil: 1. Turbocharged vehicles: Full synthetic oil is recommended. 2. Large-displacement vehicles: Full synthetic oil is recommended. 3. Direct-injection engines: Full synthetic oil is recommended.

How to Determine When Engine Oil Needs Replacement?

Here are specific details on when to replace engine oil: 1. Viscosity: Check the oil viscosity; if it lacks viscosity, the oil needs replacement. 2. Color: If the oil is black, it needs to be changed. 3. Impurities: Replace the oil when there are excessive black particles, metal shavings, or carbon deposits in the oil. 4. Smell: If the oil smells off, it should be replaced. Below is additional information on the functions of engine oil: 1. Reduces wear: It separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Heat dissipation: It carries heat back to the oil tank and then dissipates it into the air, helping the radiator to cool the engine. 3. Cleaning: It cycles carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, washing away dirt generated on the working surfaces of parts through the flow of the lubricating oil.

What is the current vehicle purchase tax rate?

Currently, the vehicle purchase tax rate is 10%. Here is some information about the vehicle purchase tax: 1. Calculation formula: The formula for calculating the tax payable is: Tax Payable = Taxable Price × Tax Rate (if the taxable price is lower than the minimum taxable price issued by the State Taxation Administration, the minimum taxable price specified by the State Taxation Administration shall be used). The taxable price is the pre-VAT amount, and the VAT rate is 17%. 2. Payment time: The vehicle purchase tax must be paid within 60 days from the date of purchase. The payment method involves bringing the owner's identity proof, vehicle price proof, and vehicle qualification proof to the local competent tax authority to declare and pay the tax. Many car 4S stores also provide a tax payment service, allowing car owners to drive their vehicles immediately after purchase without worrying about any vehicle registration procedures.
