How often is it best to change the brake fluid?
Many car owners have found that the maintenance manual recommends "changing the brake fluid every 2 years". Many car owners have doubts about the official period. Does the manufacturer's maintenance manual also have the concept of "over-maintenance"? Let's talk about brake fluid today!
Brake oil fluid, also known as brake oil, is a high-performance liquid used in the braking system of automobiles. It is mainly used in the braking system of vehicles, etc. Its main functions are to transmit energy, dissipate heat, prevent corrosion and rust, and lubricate.
When to change the brake fluid?
First, we determine the replacement time based on the time and mileage specified in the maintenance manual. Usually it is 2 years or 40,000 kilometers, whichever comes first!
01. The brake fluid becomes turbid
During regular inspection and maintenance, if the brake fluid is visibly turbid, it must be replaced!
02. The water content is found to be high
Use professional equipment to check the water content of the brake fluid. When the water content reaches 3-4%, or the boiling point is lower than 230℃, it is recommended to replace it compulsorily!
The water content in the brake fluid determines the boiling point of the brake fluid. The higher the water content, the lower the boiling point of the brake fluid. During continuous braking, it is easy to cause the brake fluid to boil and lose the brake, which is very dangerous.
