Is it dangerous to change imported brake fluid in a foreign car into Russian?
When the products of well-known western brands started disappearing from the shelves, many drivers wondered if it was safe to replace imported consumables with domestic ones. This is especially true for the brake fluid, because life and health depend on the usability of the brakes. The AvtoVzglyad portal tells how this can be done really safely and even save money.

Brake fluids are mineral (a mixture of alcohol and castor oil), glycol (a mixture of glycol ethers) and silicone (based on silicone compounds). “Mineralka” is good for everyone, except for one thing – it has a low boiling point. This makes use on machines with disc brakes impossible. Therefore, only synthetic fluids based on glycol ethers are now used.

Of course, such liquids are standardized in many countries. This is determined by safety standards. As for Russia, it has historically happened in our country that the American FMVSS 116 standard has become the most common, and it, in turn, is divided into DOT 3, DOT 4, and more recently, DOT 5 can also be found.

All of these liquids are quite reliable, as the glycol ethers contained in the composition have a high boiling point. This means that when the brakes are very hot, the fluid in the system will not boil. In addition, the excellent viscosity and lubricating properties ensure that the “brake” can be pumped through the system without any problems, both in hot and cold conditions. There is only one drawback – hygroscopicity.

That is, such a liquid quickly absorbs moisture, and when saturated with it, it loses all its benefits. The boiling point also decreases, the viscosity decreases at high temperatures and increases at low temperatures. Therefore, the fluid must be changed. Usually this happens every two years or after 40,000 km.

And here the question arises: is it possible to replace a foreign liquid with a Russian one? After all, many Western companies have already left the Russian market, and there are problems with the purchase of a “company”.

Since the DOT standards are the same for everyone, it is possible to use Russian brakes. They are in no way inferior in their properties to imported products, as well as cheaper. Do not forget that all car factories that produce foreign cars in our country have long used household liquids for primary filling on their conveyors.

It remains only to find out which fluid standard is suitable for your car, for example DOT 4 or DOT 5. This is usually in the owner’s manual of the car, so you can not go wrong.
