Precautions: Brake fluid is poisonous. Never suck up brake fluid by mouth through the hose. Fill brake fluid only into a container that closes tightly.
Brake fluid must be changed regularly as it absorbs moisture from the air through the fine pores in the brake hoses. Since the brake caliper can become very hot during braking, brake fluid with a high water content can boil. Steam bubbles form in the brake lines. Vapor, unlike liquid, can be compressed, so the pressure from the brake pedal will no longer be transferred to the individual wheel brakes, i.e. they won't work. After a single occurrence of bubbles, they remain in the hydraulic brake system even after the final cooling of the brakes.
Salt on winter roads or salty sea air speeds up the penetration of water into the brake fluid. Change the brake fluid more frequently if necessary.
Change the brake fluid every 3 years, preferably after the end of cold weather.
Brake fluid is quite caustic and should therefore not come into contact with painted surfaces of the vehicle. If this does happen, wash it off immediately with plenty of water.
For these reasons, brake fluid should only be stored in a closed container. Liquid that has been stored for a long time and whose container has been opened at least once cannot be used.
Brake fluid must not come into contact with mineral oils and solvents. Even small amounts of mineral oil will make the brake fluid unusable or cause the brake system to fail. Plugs, cuffs and covers of the brake system will be damaged in contact with mineral substances (oils, solvents, gasoline, etc.). Never use oily cloths to clean the parts. О Do not reuse brake fluid that has already been used in the brake system. When bleeding the brake system, also use only fresh brake fluid.
Brake Fluid Requirements: DOT 4 or Super DOT 4.
Note: Only use brake fluid of the specified standard, as plastic and rubber parts of the brake system are designed to use only a certain type of fluid.
Do not drain old brake fluid down the drain.
