■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking
efficiency. Use only newly opened brake fluid.

Take care as brake fluid can harm your hands and eyes and damage painted
surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.
NOTICE
