WARNING Risk of an accident due to
va pour poc kets form ing in the brake sys‐
tem
The brake fluid cons tantly absorbs moi sture
from the air. This lo wersthe boiling point of
th e brake fluid. If the boiling point is too lo w,
va pour poc kets may form inthe brake sys‐
te m when the brakes are applied hard.
This impairs the braking ef fect. #
Have the brake fluid rene we d at the
