In order to ensure the operating
8
reliability of the brake system,
make sure that the brake pads
70
are not worn beyond their mini-
mum thickness.
Have the brake pads replaced
by a specialist service facil-
ity, preferably an authorized
BMW Motorrad retailer.
Checking front brake fluid
level
A low fluid level in the
z
brake reservoir can allow air
to penetrate the brake system.
This significantly reduces braking
efficiency.
Check brake fluid level
regularly.
Make sure ground is level and
firm and hold motorcycle verti-
cally.
Check brake fluid level in front
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 horizon-
tal)
If brake fluid level falls below the
approved level:
Have the defect corrected as
soon as possible by an autho-
rized workshop, preferably an
authorized BMW Motorrad re-
tailer.
