How many kilometers does a car need to replace the brake fluid?
1 Answers
Generally speaking, the replacement cycle of brake fluid is 2 years or 40,000 kilometers, but it still depends on the cycle specified in the user manual. The following is the relevant introduction of brake fluid: 1. Brake fluid can ensure flexible transmission of braking force under working conditions such as high temperature, severe cold, high speed, and humidity. 2. It is not corrosive to the metal and non-metal materials of the braking system. 3. It can effectively lubricate the moving parts of the braking system and extend the service life of the brake wheel cylinder and rubber cup. 4. The current domestic brake fluid standard GB12981-2012 "Motor Vehicle Brake Fluid" is a mandatory standard, with a total of 15 technical indicator requirements, which are appearance, equilibrium reflux boiling point, wet equilibrium reflux boiling point, kinematic viscosity (100℃, -40℃), pH value, liquid stability, corrosiveness, low-temperature fluidity and appearance, evaporation performance, water tolerance, liquid compatibility, oxidation resistance, rubber compatibility, travel simulation performance and rust prevention performance.
