Mixing brake fluids can lead to a decline in the performance indicators of the brake fluid. Different brands and types of brake fluids have different formulations, and even if they are relatively compatible or labeled as mixable or substitutable, they should not be mixed for long-term use. Below is some extended information about brake fluid: 1. Brake fluid is a liquid medium that transmits braking pressure in hydraulic braking systems, used in vehicles equipped with hydraulic braking systems. 2. Brake fluid, also known as hydraulic brake fluid or brake oil, referred to as Brake Fluid in English, is an indispensable part of the braking system. In the braking system, as a medium for force transmission, the liquid cannot be compressed, and the pressure output by the master cylinder is directly transmitted to the wheel cylinders through the brake fluid. 3. Alcohol-based brake fluids are used, but their disadvantage is a relatively low boiling point, which can easily lead to vapor lock during high-temperature driving, and they perform poorly in low temperatures.

How often should the diesel fuel filter be replaced?

Diesel fuel filters should be replaced every 5,000 kilometers. The function of a diesel fuel filter is to remove impurities from the fuel, and it needs to be replaced after a period of use to ensure optimal filtration performance. The replacement intervals for diesel fuel filters vary among different vehicle brands. Generally, external diesel fuel filters should be replaced approximately every 20,000 kilometers, while internal diesel fuel filters should be replaced every 40,000 kilometers. Impurities in the fuel can clog the fuel injectors and also adhere to the intake ducts, cylinder walls, and other areas, leading to carbon buildup and poor engine performance. Diesel fuel filters are used to remove impurities from the fuel and are also known as fuel-water separators or diesel fine filters, featuring microporous paper filter elements.

What Do the Specifications of Car Tires Mean?

Car tire specifications are commonly represented by a set of numbers. The first number indicates the tire section width, and the latter denotes the rim diameter, measured in inches. For example, 205/55R19 represents a radial tire with a width of 205 millimeters, an aspect ratio of 55, and a rim diameter of 19 inches. Car tires are one of the essential components of a vehicle, directly contacting the road surface. Together with the car suspension, they help mitigate the shocks experienced during driving, ensuring good ride comfort and smooth driving performance. They also maintain excellent adhesion between the wheels and the road surface, enhancing the vehicle's traction, braking, and off-road capabilities, while bearing the car's weight. The crucial role tires play in automobiles is increasingly being recognized.
