Brake system - with BMW Integral ABS
Fully 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 ideal braking-force distribu-
tion between front and rear
wheels, and applies the brakes
accordingly.
The ideal baking-force distribu-
tion depends on load and is
recalculated every time the ABS
controller comes into action.
In a fully integral brake configu-
ration , the integral braking
function is activated by either
the handbrake lever or the foot-
brake lever.
Brake servoThe 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, the 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, thus
contributing significantly to
road safety.

d Warning:
If the BMW Integral ABS fails
in both brake circuits, a RESI-
DUAL BRAKING FUNCTION
only is available! (b 67)
d Warning:
If the RESIDUAL BRAKING
FUNCTION (
b 67) is active,
maintain a defensive riding
style and proceed immediate-
ly to a specialist workshop,
preferably an authorised
BMW Motorrad dealer.
*n depending on national-market
specification
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
machine if the brakes are ap-
plied too hard and the front
wheel locks or the rear wheel
lifts clear of the ground as a
result of a high level of front
tyre adhesion. Have the
defect rectified immediately
by a specialist workshop,
preferably an authorised
BMW Motorad dealer.

Fluid level in BMW Integral ABS too low.
Check the motorcycle as follows:
–
Ignition OFF: is brake pressure OK at
the brake levers?
– Are the brakes acting on both wheels?
– Is the brake system leaktight, no signs
of brake fluid escaping?
The brake system is defective if the test
outcome is negative.

Fluid level in the BMW Integral ABS is too

d Warning:
Do not ride the motorcycle if you
have any doubts about the
dependability of the brake system.

Arrive safely
Training means extra safety
Cornering and braking
need to be practiced
Develop a “sixth sense ” for
potentially dangerous situa-
tions. What this means: look
ahead, plan how to avoid possi-
bly dangerous situations and
study other road users' behav-
iour with a degree of healthy
scepticism.
– Take bends smoothly and
rhythmically, avoiding violent
braking and acceleration
– Approach bends slower than
you feel they can be taken; a
neat riding style will get you to
your destination more safely
than sheer speed
– Ride at the inner edge of the
ideal line, look ahead and plan
to leave the bend as smoothly
as you entered it Allow for reaction time when
judging braking distances.
–
At 50 km/h (approx. 30 mph),
for instance, every second
lost represents a further dis-
tance of about14 metres (46
feet) before the brakes are
applied
– At 90 km/h (approx. 56 mph),
this distance grows to 25
metres (82 feet)
Practice applying the brakes
with and without an extra load
on the motorcycle, and study its
reactions on various kinds of
road surface.
Work up to the wheel lock limit
gradually.
BMW has a worthwhile safety
contribution to make in this area
too – BMW Safety Training.
These programmes are a won-
derful opportunity: systematic
basic and follow-up training
enables you to master situa-
tions close to the limit and keep
your motorcycle under
supreme control whatever
happens.
