ABS anti-lock braking
system
ABS prevents the wheels from
locking on braking, making a
major contribution to road
safety.
Rising rear wheel
With strong adhesion between
the tires and the road, the front
wheel locks either very late or
not at all when the brakes are
applied strongly. Accordingly,
the ABS control only needs to
intervene very late or not at all.
In this case, the rear wheel can
rise, which can lead to the
motorcycle rolling over.
Heavy braking can cause
the rear wheel to rise.
Bear in mind that the ABS
control is unable to provide
protection in every case where
the rear wheel rises.c
Residual braking function
With the ignition switched off,
during the self-diagnosis and in
the event of a fault in the
BMW Integral ABS, the brake
circuits concerned only have
the residual braking function.
The residual braking function is
the braking power without the
hydraulic servo assistance of
the BMW Integral ABS. Under
these circumstances, there-
fore, you must apply consider-
ably higher pressure to the
brake levers in question in
order to apply the brakes, and
lever travel is longer. When the
residual braking function 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 par-
tially or entirely unavailable.
Without the ABS function
the wheels may lock up
during braking. Without power
braking assistance, a much
greater force is required for
braking.
Brake with foresight and cau-
tion, and avoid heavy braking.
Have the fault remedied as
quickly as possible by a certi-
fied workshop, preferably an
authorized BMW motorcycle
retailer.c
