- Brake fluid is poisonous and must never be sucked out by mouth through a hose. Pour brake fluid only into containers that cannot be misused.
- Brake fluid is aggressive and must therefore not come into contact with the paintwork, otherwise it must be wiped off and washed with plenty of water.
- Brake fluid is hygroscopic, meaning it picks up moisture from the air. Therefore, brake fluid should only be stored in closed containers.
- Brake fluid that has already been filled into the brake system must not be reused. When removing air from the brake system, also fill in new brake fluid.
- Brake fluid specification: DOT 4.
- Brake fluid must not come into contact with mineral oils. Even the smallest traces of mineral oils in the brake fluid make it impossible to use or damage the brake system.
- Change the brake fluid once a year. Fluid replacement is best done after the winter period.
- Dispose of old brake fluid at local collection points for special waste, do not dispose of it in the sewer.
