If the wear indicating marks are
no longer clearly visible:
Have the brake pads replaced
by a specialist workshop,
preferably an authorised BMW
Motorrad dealer.Checking rear brake pad
thicknessMake sure the ground is level
and firm and place the motor-
cycle on its stand.
Brake pads worn past
the minimum permissible
brake-pad thickness can cause
a reduction in braking efficiencyand under certain circumstances
they can cause damage to the
brake system.
In order to ensure the dependab-
ility of the brake system, do not
permit the brake pads to wear
past the minimum permissible
brake-pad thickness.
Visually inspect rear brake
pads1from behind to
ascertain their thickness.

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.
Check the brake fluid level in
front reservoir1.
Wear of the brake pads
causes the brake fluid level
in the reservoir to sink.Brake fluid level, front
