Generally, if the color of the brake fluid has changed, it indicates that the brake fluid is definitely too dirty and needs to be replaced. The relevant introduction to brake fluid is as follows: Introduction to Properties: Brake fluid, fully known as "Automotive Brake Fluid," is a liquid used in hydraulic braking systems to transmit pressure to stop the rotation of the wheels. The quality of the brake fluid and whether it is correctly selected and used directly affect driving safety. With the rapid development of the automotive industry and the increasing trend of high-speed vehicles, the role of brake fluid has become even more crucial. Working Principle: When the driver steps on the brake pedal, the force applied is transmitted by the piston in the master cylinder through the brake fluid to the wheel cylinders at each wheel, causing the friction pads to expand and stop the vehicle. When the brake is released, the return springs pull the friction pads back to their original position.

What are the anti-skid techniques for motorcycles in rainy days?

Motorcycle anti-skid techniques in rainy days are as follows: 1. Control your speed: Do not ride as usual on rainy days. Wet and slippery roads affect the braking distance of motorcycles, and sudden braking can easily cause skidding. It is recommended that riders do not follow other vehicles too closely to avoid rear-end collisions in case of sudden situations! Try to ride close to the side of the road, always pay attention to the road ahead, slow down when turning, and watch out for oil stains and mud on the ground. 2. Choose the right road surface: Select street rain tires and choose the appropriate road surface. When driving in rainy days, observe more and drive steadily and slowly. 3. Use of brakes: The key is to adjust the proportion of front and rear brake intervention when braking. The front brake intervention should not be too light, and you should not only use the rear brake. Both front and rear brakes should be used simultaneously.

Can You Not Drive on Highways Without ETC?

Vehicles without ETC can still drive on highways because ETC is not mandatory. Starting from January 1, 2020, vehicles without ETC will no longer enjoy various toll reduction benefits and can only pay tolls through manual lanes at toll stations. It might be a bit inconvenient during holidays. ETC is just a different toll collection method and has nothing to do with whether you can drive on highways. There are two toll collection methods on highways: manual toll collection and ETC toll collection. ETC stands for Electronic-Toll-Collection, which means electronic toll collection system. To apply for ETC, you need to provide the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate must include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is needed. The applicant must be between 18 and 60 years old, and the vehicle must be registered under a personal name. The working principle of ETC: Through the onboard electronic tag installed on the vehicle's windshield, it communicates with the microwave antenna in the ETC lane at the toll station. Using computer networking technology, it settles accounts with the bank in the background, allowing vehicles to pay highway or bridge tolls without stopping when passing through toll stations. Benefits of installing ETC: Time-saving: Avoid the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise, exhaust emissions, and pollution; Cost-saving: Reduce costs, decrease the frequency of vehicle starts and stops, and minimize wear and fuel consumption. Users can also enjoy toll discounts; Improved efficiency: Theoretically, ETC lanes can increase traffic efficiency by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
