Safety check
Brake system - without BMW Integral ABS
Checking brake fluid levelGradual wear of the brake pads
causes the brake fluid level in
the reservoir to sink.

Have the brake system
checked immediately if the
brake fluid level in the reser-
voir of the front or rear brake
system drops below the MIN
mark (
b 39, 40) ; have the

diately by a specialist work-
shop, preferably an
authorised BMW motorcycle
