Brake System With Bmw Motorrad Abs Oe - BMW R 1200 S Rider's Manual

Oil or grease on brakes
Oil and grease on the
brake disks and pads
considerably diminish braking
efficiency.
Especially after repair and
maintenance tasks, make
sure that the brake discs and
brake pads are free of oil and
grease.
Dirt or mud on brakes
When the motorcycle
is ridden on loose sur-
faces or muddy roads, the
brakes may fail to take effect
immediately because of dirt
or moisture on the disks or
brake pads.
Brake early until the brakes
are braked clean.
Driving on unpaved or
dirty roads leads to in-
creased brake pad wear.
Check the brake pad thick-
ness more often and replace
the brake pads sooner.
Brake system with
BMW Motorrad ABS
How does ABS work?
The maximum braking force
that can be transferred to
the road surface is partial-
ly dependent on the friction
coefficient of the road sur-
face. Gravel, ice, snow and
wet roads offer a consider-
ably poorer friction coefficient
than a dry, clean asphalt sur-
face. The poorer the friction
coefficient of the road surface
is, the longer the braking dis-
tance will be.
If the maximum transferrable
braking force is exceeded
when the driver increases the
brake pressure, the wheels
begin to block and driving
stability is lost, and a fall can
result. Before this situation
occurs, ABS intervenes and
adjusts the brake pressure
to the maximum transferrable
OE
braking force. This enables
the wheels to continue to turn
and maintains driving stability
regardless of the road surface
condition.
What happens when
rough roads are
encountered?
Bumpy or rough roads
can briefly lead to a loss of
contact between the tires
and the road surface, until
the transferrable braking
force is reduced to zero.
If braking is carried out in
this situation, ABS must
reduce the brake pressure
to ensure driving stability
when restoring contact to the
road. At this point in time, the
BMW Motorrad ABS must
