Changing the brake fluid
Brake fluid absorbs moisture from the air over
time. This accumulation of water lowers the
boiling point and, under certain operating condi-
tions, can affect the braking performance.
Therefore have the brake fluid changed in accor-
dance with the change intervals stated in the
brochure "Maintenance".
