from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low ,vapo rpockets may form in the
brake system when the brakes are applied
hard .This would impair braking efficiency.
There is arisk of an accident.
You should have the brake flui drenewe dat
the specified intervals.
!If the brake flui dlevelint he brake flui dres-
ervoir has fallen to the MIN mark or below,
check the brake system immediatel yfor
leaks. Also check the thickness of the brake
linings. Visi taqualified specialist workshop
immediately.
Do not add brake fluid. This does not correct
