brake fluid reservoir 1.
Wear of the brake pads
causes the brake fluid level
in the reservoir to sink.
Brake fluid level, front
DOT4 brake fluid
It is impermissible for the
brake fluid level to drop be-
low the MIN mark. (Brake-
fluid reservoir horizontal)
If the brake fluid level drops be-
low the permitted level:
A low fluid level in the
brake reservoir can allow air
to penetrate the brake system.
This significantly reduces braking
efficiency.
Check the brake-fluid level at
regular intervals.
Have the defect rectified as
quickly as possible by a spe-
cialist workshop, preferably
an authorised BMW Motorrad
dealer.
