Disc brakes furnish optimum decelera-
tion and braking control as well as
greater fade resistance under heavy
use.
Limited vehicle use, extended periods
with the car parked or in storage and
light loading will increase the tendency
for corrosion to form on the rotors, and
dirt to accumulate on the pads. This
happens because the minimum pres-
sure between the pad and the disc
required for the self-cleaning function
of the disc brakes is not achieved.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
a
Use only original BMW-approved
brake pads, as otherwise vehicle autho-
rization is no longer valid.c
Driving notes While driving in wet conditions and in
heavy rain, it is a good idea to apply
light pressure to the brake pedal every
few miles - Watch traffic conditions to
ensure that this maneuver does not
endanger other road users. The heat
generated in this braking process helps
dry the brake pads and rotors.
Maximum braking force is obtained
while the wheels continue to rotate,
peaking when the wheels remain on the
verge of locking without actually doing
so. ABS maintains this state automati-
cally. If the ABS fails, you should revert
to the staggered braking technique
described above (refer to page 106).
Extended or steep mountain descents
do not necessarily have to lead to
reduced braking efficiency; downshift
to a gear in which only minimal periodic
brake applications are required (you
can move the selector lever to the
appropriate lower range if your car is
equipped with an automatic transmis-
sion).
You can further increase the engine's
braking effect by selecting a lower gear,
downshifting as far as first gear or plac-
ing the selector lever in position 1 (2).Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead of main-
taining low to moderate pressure over
an extended period of time, you should
decelerate the vehicle by applying more
substantial force at the pedal (watch for
following traffic!) and then pausing
before repeating the application. This
staggered braking technique allows the
brakes to cool in the intervals between
active braking phases, preventing over-
heating and ensuring that full braking
capacity remains available at all times.
a
Do not allow the vehicle to coast by
pressing down the clutch pedal or shift-
ing into neutral while underway. Never
drive with the engine switched
off (!). The engine provides no braking
effect when the clutch is disengaged or
the transmission is in neutral, and there
is no power-assist for brakes and steer-
ing when the engine is not running.
Never allow floor mats, carpets or other
objects to protrude into the area around
the accelerator, clutch and brake pedals
and obstruct their movement.c
