Precautions for replacing brake fluid include: 1. Avoid introducing air into the brake fluid. Changing brake fluid requires careful coordination between two people to prevent accidental air ingress. One person should drain the fluid while observing, and the other should repeatedly press the brake pedal. New fluid must be replenished promptly and continuously. 2. Tighten the drain bolt to prevent leaks. Brake fluid is corrosive and can affect other car components. 3. Avoid introducing impurities and dust into the brake fluid. Brake fluid, also known as brake hydraulic fluid or braking liquid, is made from refined diesel distillates with thickeners and antioxidants. There are three types: mineral oil brake fluid, alcohol-based brake fluid, and synthetic brake fluid.

Can a car run at 100 km/h on the highway during the break-in period?

During the break-in period, a car can reach a speed of 100 kilometers per hour, but it is important to avoid running the engine at very high RPMs as this can increase engine wear. Additionally, avoid performing launch starts during this period as it can accelerate transmission wear. Always adhere to the break-in period usage rules when driving during this phase. The break-in period is considered complete after the first maintenance service. Key precautions for new car break-in include: 1. Warm up the car before starting: Wait 5 to 10 seconds after shifting into second gear before driving; 2. Avoid high-speed driving: New cars have speed limits during the break-in period—40 to 70 km/h for domestic cars and 100 km/h for imported cars; 3. Avoid overloading: Carrying excessive weight during the break-in period can damage mechanical components.
