Brake system - without BMW Integral ABS
Checking brake fluid level Gradual 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 31-32) have
the brake system checked
without delay, preferably an
authorised BMW motorcycle
dealer.
Changing brake fluid
d Warning:
Brake fluid is subject to
severe thermal loads and
absorbs moisture from the
atmosphere.
Consequently, the brake fluid
must be changed regularly
(
b Maintenance Instructions,
Chapter 1) by a specialist
workshop, preferably an au-
thorised BMW motorcycle
dealer.
