Brake fluid (BMW 5 Series E39)

When handling brake fluid, pay attention to the following:

Brake fluid is poisonous. Never suck brake fluid out with your mouth through a hose. Pour brake fluid only into containers from which accidental consumption is excluded.

Brake fluid is caustic and therefore should not come into contact with the car's brake fluid, otherwise it should be wiped off immediately and the contact area should be washed with water.

Brake fluid is hygroscopic, meaning it absorbs moisture from the air. Therefore, store brake fluid only in closed containers.

Brake fluid that has already been used in the brake system cannot be reused. When bleeding air from the brake system, only new brake fluid should be used.

Brake fluid specification: DOT 4.

Brake fluid should not come into contact with mineral oils. Even minor traces of mineral oil make the brake fluid unusable or lead to failure of the brake system

Replace brake fluid every 2 years, regardless of the vehicle's mileage, if possible after the cold season.

Old brake fluid should be handed over to the local special waste authority; do not pour it down the drain.
