Can brake fluid be mixed absolutely?Can brake fluid be mixed?

well known,Brake FluidIt is a category of consumables. When the liquid level is lower than the MIN scale line, it needs to be replenished in time. But there are rumors on the Internet that there is nothing to worry about when buying brake fluid. As long as it is a good quality brake fluid, no matter what type or brand, it can be filled. So is it true that the brake fluid can definitely be mixed?

In fact, different types and brands of brake fluids cannot be mixed. After all, they contain different fluid components. If it is really mixed, it will cause the performance index of the brake fluid to decrease or a chemical reaction will occur, which will not only reduce the braking effect of the car, but also have a certain impact on the temperature resistance of the fluid, which will directly affect the driving. Safety, so everyone must not mix brake fluid. If you really want to add other types (brands) of brake fluid, you should drain off the remaining brake fluid in the fuel tank, and then thoroughly clean it with alcohol before adding new fluid.

Secondly, we have to choose the appropriate grade of brake fluid. If your car itself uses DOT3 standard brake fluid, we only need to fill it according to the standard. If you feel that the braking effect is not very good, and the heat generated during braking is very large, then we can consider a higher level of brake fluid (DOT4). And a car that uses DOT4 standard oil cannot be replaced by DOT3 (lower grade) standard, otherwise it will affect the brake system of the entire vehicle.
