Brake system - general
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
authorised BMW motorcycle
dealer.
Checking the brake
system
d Warning:
Sudden changes in play or
spongy action of the brake
lever 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
system.
Immediately seek the advice
of a specialist workshop,
preferably an authorised
BMW motorcycle dealer.

Brake system - general
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.
Checking brake pads
Brake pad wear depends on
your personal style of riding.
To ensure reliable operation of
the brakes: do not allow lining
thickness to fall below minimum
value (Service and Technical
Booklet
b Chapter 2)!

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
(see the Service and Techni-
cal Booklet
b Chapter 1),
preferably by an authorised
BMW motorcycle dealer.

Brake system - with BMW Integral ABS*
Residual braking function
d Warning:
When the ignition is switched
off, before and during
self-diagnosis (
b 72), or if the
BMW Integral ABS* fails, only
a RESIDUAL BRAKING
FUNCTION remains available
for slowing the motorcycle
(
b 71).
When the RESIDUAL
BRAKING FUNCTION is
active, you must apply
CONSIDERABLY higher
pressure to the brake lever in
question in order to apply the
brakes, and lever travel is
longer.
When the RESIDUAL
BRAKING FUNCTION is ac-
tive, the ABS function is una-
vailable in the brake systems
in question.
* Optional extra
d Warning:
When the RESIDUAL
BRAKING FUNCTION is ac-
tive, maintain a defensive
riding style and proceed im-
mediately to the nearest spe-
cialist workshop, preferably
an authorised
BMW motorcycle dealer.
L Note:
When the RESIDUAL BRAKING
FUNCTION is active, it is advis-
able to set adjuster A (
b 27) on
the front-brake lever to
position 4.

Checking lights
e Caution:
Check that all lights are operati-
onal at the start of each journey.
L Note:
If turn indicator repeater flashes
at twice the usual speed:
Defective flasher bulb.
BMW Integral ABS:
General warning light ON (
b 62):
Check brake light or tail light.
If the tail light is defective the
brake light is dimmed and acts
as a tail light. When you apply the
brakes the brake light shines at
full brightness. To change bulbs in parking
lights, headlight (dipped and
main beams), rear/brake lights,
turn indicators and the number-
plate light:
(

Service and Technical
Booklet, Chapter 2)
Headlight setting RHD/
LHD traffic
If the motorcycle is ridden in a
country where the opposite rule
of the road applies, its asym-
metric dipped beam will tend to
dazzle oncoming traffic.
Adjust the headlight according-
ly (Service and Technical
Booklet,
b Chapter 2).
Your BMW motorcycle dealer
will be glad to provide any
assistance you may require.

d Warning:
When the ignition is switched
off or if the BMW Integral ABS
fails, only a “RESIDUAL BRA-
KING FUNCTION” is available
(
b 71).
Under these circumstances
you must apply CONSIDER-
ABLY higher pressure to the brake levers in order to apply
the brakes, and lever travel is
longer.
*Optional extra
Risk of fireHigh temperatures occur at the
exhaust system, particularly if a
catalytic converter is installed.
d Warning:
Make sure that whether riding
or standing still or when the
motorcycle is parked, no easi-
ly flammable material (for
example hay, grass, leaves, clothing or luggage etc.) can
come into contact with the hot
exhaust system.

d Warning:
Engine exhaust, some of its
constituents, and certain
vehicle components contain
or emit chemicals known to
the State of California to
cause cancer and birth
defects or other reproductive
harm.
Battery posts, terminals, and
related accessories contain

Brake system - general
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 immedi-
ately.
d Warning:
The brakes have to dry before
they start to bite.
Salt on brakesThe full braking effect can be
delayed if the motorcycle is
ridden on salt-covered roads
and the brakes are not applied
for some time.
d Warning:
The layer of salt on the brake
discs and pads must first be
worn away.

Oil and grease on brakes
d Warning:
Brake discs and pads must be
free from oil or grease.
Dirt or mud on brakesWhen riding on loose surfaces
or muddy roads, the brakes
may fail to take effect immedi-
ately because of dirt or mois-
ture 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.
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 autho-
rised BMW motorcycle dealer.

Brake system - with BMW Integral ABS*
Sensitive electronic
control
It takes skill and sensitive con-
trol of the brakes to pull up
safely on a motorcycle. If the
front wheel brake locks and the
wheel skids, the necessary lon-
gitudinal and lateral stabilising
forces are lost, and a fall can
result.
For this reason, the rider sel-
dom makes full use of available
braking performance in an
emergency.
* Optional extra
BMW Integral ABS is the latest-
generation BMW ABS develop-
ment: by preventing both
wheels from locking and opti-
mising braking-force distribu-
tion by means of the integral
function, it offers much
improved braking performance
(
b 70). Full use is made of tech-
nical braking capacity to mini-
mise braking distances, even
when road conditions are poor.
When the motorcycle is ridden
in a straight line, the
BMW Integral ABS is able to
handle emergency braking
safely.
