Checking brake fluid levelGradual wear of the brake pads
causes the brake fluid level in
the reservoir to drop.
d Warning:
If brake fluid level in the fluid
reservoirs for the front or rear
brakes has dropped below
the MIN mark (
b 33, 34) have
the brake system checked
without delay by a specialist
workshop, preferably an au-
thorised BMW motorcycle
dealer.

severe thermal loads, and
absorbs moisture from the
atmosphere.
Consequently, the brake fluid
must be changed regularly
by a specialist workshop,
preferably an authorised
BMW motorcycle dealer.
