Notes on brake fluid
Observe the notes on operating fluids
(
page 417).
/
& WARNING Risk of an accident due to
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point is too low,
vapour pockets may form in the brake system
when the brakes are applied hard.
This impairs the braking effect.
