Brake fluid manufacturers offer a wide range of products. However, it can be quite difficult for the buyer to choose a product of the proper quality. To facilitate the purchase procedure, you need to pay attention to several main points.
Instructions
Step 1
When buying brake fluid, you should not rely on someone else's advice and recommendations. The fact is that there is a special manual for the operation of the car (the manufacturer specifies the TJ standard there), and you should be guided by it. The standard noted there will be optimal for the braking system of your particular car. There are two such standards in total - this is DOT, which stands for Department of Transportation, and SAE J1703. However, it should be noted that the most frequently used is the first of them.
Step 2
The most important thing is not to spare money to buy a good brake fluid. When choosing a product, make sure that it is manufactured in accordance with all quality standards. TG packaging must be airtight (this will be indicated by the fact that when lightly squeezed from the sides, the packaging is springy). It is best if there is a foil membrane under the lid: it does not allow water to pass through. In addition, the liquid itself should be free of sediment and transparent. Among the foreign firms producing such products are Castrol, Lockheed, ZIC, Shell and some others. All listed companies give each TJ their own designation according to the DOT classification. Russian companies produce goods that meet the requirements of only DOT3 and DOT4. They will correspond to such fluids as "Tom" and "Neva", as well as "Dew".
Step 3
The higher the DOT classification, the higher the price of brake fluid will be. However, keep in mind that a cheap product can get you in a lot of trouble. The fact is that such a TJ will be too hygroscopic (that is, it can easily attract and absorb water). This very moisture, once it gets into the liquid, will bring pollution with it. In addition, the inner surfaces of lines and cylinders will constantly corrode.
