Brake system - general
Oil-free and grease-free
brakes
d Warning:
Brake discs and pads must be
free from oil and grease.
Dirt on the brakesWhen you are riding on loose
surfaces or 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.
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.

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.
OEOptional 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 74). 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 Inte-
gral ABS is able to handle
emergency braking safely.

Extra safety reserves!But remember: the potentially
shorter braking distances
which BMW Integral ABS per-
mits must not be used as an
excuse for careless riding. ABS
is primarily a means of ensuring
a safety margin in genuine
emergencies.
– You have to familiarise your-self with the new, electroni-
cally assisted braking. Try the
brakes several times when
you take your motorcycle out
for the first time. Find out for
yourself how the brakes feel
– 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 BMW Integral
ABS is unable to counteract
their effects.

Partially integral brakesThe integral brake function
interlinks the front and rear
brakes, so both wheels are
braked when you operate the
brake lever.
The electronic controller in the
BMW Integral ABS computes
the braking-force distribution
between front and rear wheels,
and applies the brakes accord-
ingly.
Braking-force distribution
depends on load and is recal-
culated every time the ABS
controller comes into action.
In this partially integral brake
configuration, the integral brak-
ing function is activated only
when you pull the handbrake
lever. The footbrake lever acts
only on the rear brake.Brake boosterThe hydraulic pump in the BMW
Integral ABS actively boosts the
braking force acting on the
wheel when the brakes are
applied.
By boosting the braking force in
this way, BMW Integral ABS
achieves higher braking effi-
ciency than standard brake
systems.
ABS - anti-lock
brake system
ABS prevents the wheels lock-
ing under heavy braking when
the motorcycle is travelling in a
straight line, thus contributing
significantly to road safety.

RESIDUAL BRAKING
FUNCTION
If the BMW Integral ABS devel-
ops a fault, a RESIDUAL BRAK-
ING FUNCTION only is available
in the brake circuits in question.
The RESIDUAL BRAKING
FUNCTION is the braking effi-
ciency without the hydraulic
servo assistance of the BMW
Integral ABS. Under these cir-
cumstances, you must apply
CONSIDERABLY higher pres-
sure to the brake levers in ques-
tion in order to apply the brakes,
and lever travel is longer. When
the RESIDUAL BRAKING FUNC-
TION is active, the ABS function
is unavailable in the brake system
in question. When the RESIDUAL
BRAKING FUNCTION is active,
the integral braking function is
partially or entirely unavailable.
d Warning:
When the RESIDUAL BRAK-
ING FUNCTION is active,
maintain a defensive riding
style and proceed immediate-
ly to the nearest specialist
workshop, preferably an au-
thorised 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.
The RESIDUAL BRAKING
FUNCTION is active under the
following circumstances:
– Ignition off
– Before and during self-diag- nosis (
b 76)
– Fault in the BMW Integral ABS (
b 79)
L Note:
When the RESIDUAL BRAKING
FUNCTION is active for both
brake circuits, the noise of the
pump is no longer audible when
you operate the brake levers.

Self-diagnosis with pull-
away test
The BMW Integral ABS per-
forms self-diagnosis and a pull-
away test to ensure its operabil-
ity.
Self-diagnosis is performed
automatically when you switch
on the ignition.
d Warning:
Self-diagnosis is not per-
formed unless both brake le-
vers are in their fully released
positions.
Only the RESIDUAL BRAKING
FUNCTION is available until
self-diagnosis is completed
(b 75).  Release the brake levers, if
necessary
 Switch on the ignition
Initially:
– ABS warning light 1:
Flashes at 4 Hz
– General warning light 2:

bSelf-diagnosis is in
progress
Then:

L Note:
Starting on gradients:
Always switch on the ignition
with gear engaged, clutch lever
released and both brake levers
released.
This is the only way of ensuring
that self-diagnosis is per-
formed. When self-diagnosis
completes, apply the brakes,
disengage the clutch and start

d Warning:
If the BMW Integral ABS fails
in both brake circuits, a RE-
SIDUAL BRAKING FUNCTION
only is available! (b 75)

d Warning:
If there is a fault in the ABS
system, the reserves of safety
normally afforded by ABS are
not available until the defect
has been put right.
There is a risk of dropping the
motorcycle if the brakes are
applied too hard and the
w h ee ls l o ck o r th e r e ar w h ee l
lifts clear of the ground as a
result of a high level of tyre
adhesion. Have the defect
rectified immediately by a
specialist workshop, prefera-
bly an authorised
BMW motorcycle dealer.
