Work on the brake system
d Warning:
To ensure reliability have all
work on the brake systems
carried out by a specialist
workshop, preferably an au-
thorised BMW motorcycle
dealer.
Brake system, checking
d Warning:
Sudden changes in play or
spongy action of the brake le-
ver indicate a fault in the
brake system.
Before riding off, therefore,
always check the resistance
of the front and rear brake le-
vers and test operation of the
brakes.
Do not ride the motorcycle if
you have any doubts about
the safety of the brake sys-
tem.
Do not, under any circum-
stances, adjust the screw in
the pedal of the footbrake.
Immediately seek the advice
of a specialist workshop,
preferably an authorised
BMW motorcycle dealer.

Checking brake pads
d Warning:
Have the brake pads replaced
before they wear to the mini-
mum permissible thickness:
have the work performed
by a specialist workshop,
preferably an authorised
BMW motorcycle dealer. Brake pad wear depends on
your personal style of riding.
To ensure reliable operation of
the brakes: do not allow the
pads to wear past the minimum
specified thickness (b Mainte-
nance Instructions, Chapter 2)

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.
Changing the brake fluid
d Warning:
Brake fluid is exposed to
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.

Braking
Wet bra kesAfter the motorcycle has been
washed, ridden through water
or ridden in the rain, the brake
discs and pads may be wet (or
iced-over in winter), and may
not take effect immediately.
d Warning:
The brakes have to dry before
they start to bite.
Salt on brakesThe brakes may fail to take
effect immediately if the motor-
cycle was ridden on salt-cov-
ered roads and the brakes were
not applied for some time.
d Warning:
The layer of salt on the brake
discs and pads has to be
worn off before the brakes
start to bite.

Braking
Dirt or mud on brakesWhen riding on muddy roads,
the brakes may fail to take
effect immediately because of
dirt or moisture on the discs or
brake pads.
d Warning:
The brakes must first be
applied until the discs and
pads are clean.
Dirt on the brakes increases
the rate of pad wear.
Oil and grease on brakes
d Warning:
Brake discs and pads must be
free from oil and grease.
d Warning:
If the brake lever can be moved
right to the limit of its travel, this
indicates a mechanical or hy-
draulic fault. The brake system is
defective.
Immediately consult a specialist
workshop, preferably an author-
ised BMW motorcycle dealer.

ABSOE – familiarisation phase
Sensitive electronic
control
It takes skill and sensitive con-
trol of the brakes to pull up
safely on a motorcycle. As the
front wheel locks, it loses its
stabilising centrifugal force, and
even a professional rider faces
an almost certain fall.
For this reason, the rider sel-
dom makes full use of available
braking performance in an
emergency.
Anti-lock braking at both
wheels greatly reduces the risk
of accidents even when road
conditions are poor, and short-
ens braking distance by making
more efficient use of the motor-
cycle’s braking capability.
ABS enhances safety in emer-
gency-braking situations, par-
ticularly when the motorcycle is
travelling in a straight line.Extra safety reservesBut remember: the potentially
shorter braking distances
which ABS permits must not be
used as an excuse for careless
riding. ABS is primarily a means
of ensuring a safety margin in
genuine emergencies.
– Never ride without due care and attention, or assume that
good fortune will protect you
from your own foolhardiness
– Keep within the permitted speed limits
– Take care when cornering. When you apply the brakes on
a corner, the motorcycle's
weight and momentum take
over and even ABS is unable
to counteract their effects
