Brakeperformance
is
mainly
affected
by
three
things
:
the
leve¡
and
condition
of
the
brake
fluid,
the
system's
abilíty
to
create
and
maintain
hydraulic
pressure,
and
the
condition
of
the
friction
components
.
Air
in
the
Brake
fluid
will
make
the
Brake
pedal
feel
spongy
during
braking
or
will
increase
the
Brake
pedalforce
required
to
stop
.
Fluid
contaminated
by
moisture
or
dirt
can
corrode
the
system
.
Inspect
the
Brake
fluid
inside
the
reservoir
.
Ifit
is
dirty
or
murky,
or
is
over
a
year
old,
the
fluid
should
be
replaced
.
Visually
check
the
hydraulic
system
startingat
the
master
cylinder
.
To
check
the
function
of
the
master
cylinder
hold
the
brake
pedal
down
hard
with
the
engine
running
.
The
pedal
should
feelsolid
and
stay
solid
.
If
the
pedal
slowly
falls
to
the
floor,
either
the
master
cylinder
is
leaking
internally,
or
fluid
is
leaking
externally
.
If
no
leaks
canbe
found,
the
master
cylin-
der
is
faulty
and
should
be
replaced
.
Check
all
Brake
fluid
lines
and
couplings
for
leaks,
kinks,
chafing
and
corrosion
.
Check
the
Brake
booster
by
pumping
the
Brake
pedal
ap-
proximately
10
times
with
the
engine
off
.
Hold
the
pedal
down
and
start
the
engine
.
The
pedal
should
fa¡¡
slightly
.
If
not,
check
for
any
visiblefaults
before
suspecting
a
faulty
brake
booster
.
Check
for
strong
vacuum
at
the
vacuum
hose
fitting
at
the
booster,
and
check
the
non-retum
valve
for
one-way
flow
.
Worn
or
contaminated
brake
pads
will
cause
poor
braking
performance
.
Oil-contaminated
or
glazed
pads
will
cause
stopping
distances
to
increase
.
Inspect
the
rotors
for
glazing,
discoloration
and
scoring
.
Steering
wheel
vibration
while
braking
at
speed
is
often
caused
by
warped
rotors,
but
can
also
be
caused
byworn
suspension
components
.

WARNING
-
On
cars
with
All
Season
Traction
(AST),
special
BMW
service
equipment
is
required
to
properly
bleed
the
ABS/AST
system
.
For
safety
reasons,
the
brake
system
on
carswith
ABS/AST
must
not
be
bled
using
the
procedures
described
inthis
repair
group
.
BLEEDING
BRAKES
Brake
bleeding
is
usually
done
for
one
of
two
reasons
:
Ei-
ther
to
replace
oíd
brake
fluid
as
part
of
routine
maintenance
or
to
expel
trapped
air
in
the
system
that
resulted
from
open-
ingthe
brake
hydraulic
system
during
repairs
.
BLEEDING
BRAKES
Alwaysuse
new
brake
fluid
from
an
unopened
container
.It
is
important
to
bleed
the
entire
system
when
any
part
of
the
hydraulic
system
has
been
opened
.
On
cars
not
equipped
with
traction
control
(AST),
brake
system
bleeding
should
be
done
with
a
pressure
bleeder
.
On
cars
with
AST,
brake
bleed-
ing
should
be
done
by
an
authorized
BMW
dealer
.
