Read off brake fluid level at
brake-fluid reservoir 1.
The brake fluid level in the
brake-fluid reservoir drops
due to brake pad wear.
Front brake fluid level
Brake fluid (DOT4)
The brake fluid level must
not fall below the MIN mark.
(Brake-fluid reservoir hori-
zontal)
If brake fluid level drops below
permissible level:
A low fluid level in the
brake reservoir can allow air
to penetrate the brake system.
This significantly reduces braking
efficiency.
Check brake fluid level
regularly.
Have the defect corrected as
soon as possible by a special-
ized workshop, preferably an
authorized BMW Motorrad re-
tailer.
Checking rear brake fluid
level
Make sure ground is level and
firm and hold motorcycle verti-
cally.
