Brake System, General - BMW R 1200 R Rider's Manual

-- for each tyre until the tyre-
5
pressure signal is received for
the first time. The sensors
76
continue to transmit the
measured-value signals for
approximately 15 minutes
after the motorcycle comes to
a stop.
The control unit can
administrate four sensors, so
z
two different sets of wheels
with RDC sensors can be
alternated on the motorcycle.
An error message is issued
if wheels without sensors
are fitted to a motorcycle
equipped with an RDC control
unit.
Temperature
compensation
The tyre-pressure readings
shown by the multifunction
display are temperature-com-
pensated; the reference tyre
temperature for these read-
ings is always 20 °C. The air
lines available to the public in
petrol stations and motorway
service areas almost invari-
ably show temperature-de-
pendent tyre pressures, so in
most instances these gauge
readings will not tally with the
readings shown by the multi-
function display.
Tyre-pressure ranges
The RDC control unit differ-
entiates between three air-
pressure ranges, all of which
are parameterised for the mo-
torcycle:
Air pressure within permit-
ted tolerance.
Air pressure close to limit of
permitted tolerance.
Air pressure outside permit-
ted tolerance.

Brake system, general

Descending mountain
passes
There is a danger of the
brakes fading if you use
only the rear brakes when
descending mountain passes.
Under extreme conditions, the
brakes could overheat and
suffer severe damage.
Use both front and rear
brakes, and make use of the
engine's braking effect as
well.
Wet brakes
After the motorcycle has
been washed, ridden
through water or ridden in
the rain, the brake discs and
pads might be wet and the
brakes might not take effect
immediately.
Apply the brakes in good time
