To achieve the shortest
braking distance, it is neces-
sary to apply the front brake
gradually and with increasing
force. This makes best use of
the dynamic increase in load
on the front wheel. At the
same time, the clutch should
be disengaged.
In emergency braking as it is
often taught, in which the
brake pressure is generated
as quickly as possible and with
all possible force, the dynamic
load distribution cannot follow
the increasing deceleration
and the braking force cannot
be completely transferred to
the road. The ABS has to
intervene to ensure that the
front wheel does not lock up;
this reduces the brake pres-
sure and the braking distance
is extended.
What happens if ABS control
fails?
A fault in BMW Motorrad
Integral ABS is indicated by a
corresponding warning dis-
play in the instrument cluster.
If only ABS control fails, the
Integral system and the brake
servo action remain opera-
tional. If these systems also
fail, the residual brake function
is applied. In this case, the
forces to be applied to the
brake levers will be signifi-
cantly higher and the lever
travel required will be longer.
The residual brake function is
a mechanical function and is
always available in the event
of the failure of the BMW
Motorrad Integral ABS,
whatever the battery condi-
tion. It meets all requirements
of legislation around the world
on the design of brakes for
motor vehicles and allows the
rider to brake the motorcycle.
The following notes must be
observed for riding with the
residual braking function:
• set the brake lever to
maximum travel
• always brake with both front
and rear brakes
• where it is safe to do so, try
out the brakes so that you
can learn the brakes'
response characteristics
• be aware of the prevailing
road conditions and adapt
your braking force
accordingly
• since this is an emergency-
run function, you should visit
a specialist workshop, or
better still a BMW Motorrad
dealer, as quickly as
possible
