cate any malfunctions, and the brake
assist system is operating properly.
.You might feel that the brake pedal is
applied by lighter force and generates a
greater braking force.
.You might hear an ABS operating
noise from the engine compartment.&Disc brake pad wear warning
indicatorsThe disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.
If a squeaking or scraping noise is heard
from the disc brakes while braking, im-
mediately have your vehicle checked by
your SUBARU dealer.
&High performance brake sys-
tem (STI)Your vehicle is equipped with large, high
performance brake pads that provide
optimum braking force under various driv-
ing conditions. The brake pads have the
following characteristics.
Brake noises
The brake pads are made of iron-based
material. Therefore, unusual noise may be
heard when depressing the brake pedal
slightly before stopping completely. How-
ever, this does not indicate a malfunction.
Discoloration
Frequent severe driving, such as repeated
driving on sharp uphill or downhill grades,
can cause discoloration of the paint on the
brake calipers. The discoloration will not
affect the braking performance.
Stuck brake pads
.If the vehicle is left parked for an
extended period of time with the brake
system wet, the iron in the brake pads may
form rust and cause the brake pads and
disc rotors to stick together. This may
result in noise or vibration while driving. If
this occurs, fully depress the brake pedal
several times to free the brake pads.
.If the vehicle is left parked for an
extended period of time in a cold tempera-ture, the brake pads and disc rotors may
be frozen and stuck together. In this case,
it may be difficult to start the vehicle.
Brake dust
Due to the material used for the brake
pads, the wheels may become covered in
brake dust. This is not a malfunction, and
will not affect the brake performance.

CAUTION
.It is recommended that you dis-
connect the vehicle battery be-
fore replacing the brake pad.
However, it is dangerous to dis-
connect the vehicle battery. We
recommend that you have your
SUBARU dealer replace the brake
pad.
.If you continue to drive despite
the scraping noise from the audi-
ble brake pad wear indicator, it
will result in the need for costly
brake rotor repair or replace-
ment.&Breaking-in of new brake
pads (models with electronic
parking brake system)When replacing the brake pad, use only
genuine SUBARU parts. After replace-
ment, break in the new parts as follows.
!Brake pad
While maintaining a speed of 30 to 40 mph
(50 to 65 km/h), step on the brake pedal
lightly. Repeat this five or more times. Also,
apply and release the electronic parking
brake five or more times.
&Breaking-in of new brake
pads and linings (models
without electronic parking
brake system)When replacing the brake pad or lining,
use only genuine SUBARU parts. After
replacement, break in the new parts as
follows.
!Brake pad and lining
While maintaining a speed of 30 to 40 mph
(50 to 65 km/h), step on the brake pedal
lightly. Repeat this five or more times.
!Parking brake lining
1. Drive the vehicle at a speed of approxi-
mately 22 mph (35 km/h).
2. With the parking brake release button
pushed in, pull the parking brake lever
SLOWLY and GENTLY (pulling with a
force of approximately 33.7 lbf [150 N,
15.3 kgf]).
3. Drive the vehicle for approximately 220
yards (200 meters) in this condition.
4. Wait 5 to 10 minutes for the parking
brake to cool down. Repeat this proce-
dure.
5. Check the parking brake stroke. If the
parking brake stroke is out of the specified
range, adjust it by turning the adjusting nut
located on the parking brake lever.
Parking brake stroke:
7–8 notches / 45 lbf (200 N, 20.4 kgf)
WARNING
Select a safe location and situation
for break-in driving.
CAUTION
Pulling the parking brake lever too
forcefully may cause the rear wheels
to lock. To avoid this, be certain to
pull the lever up slowly and gently.
