Excess moisture in the brake fluid can cause a dangerous loss of braking effi-

When filling the reservoir

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.

Check the battery as follows:
