Brake booster
If the brake booster does not operate as
described in the following, have it checked
by your SUBARU dealer.
1. With the engine off, depress the brake
pedal several times, applying the same
pedal force each time. The distance the
pedal travels should not vary.
2. With the brake pedal depressed, start
the engine. The pedal should move slight-
ly down to the floor.
3. With the brake pedal depressed, stop
the engine and keep the pedal depressed
for 30 seconds. The pedal height should
not change.
4. Start the engine again and run for ap-
proximately one minute then turn it off.
Depress the brake pedal several times to
check the brake booster. The brake boost-
er operates properly if the pedal stroke de-
creases with each depression.Brake pedal
Check the brake pedal free play and re-
serve distance according to the mainte-
nance schedule in the “Warranty and
Maintenance Booklet”. „Checking the brake pedal free
play
1) 0.02 – 0.08 in (0.5 – 2.0 mm)
Stop the engine and firmly depress the
brake pedal several times. Lightly pull the
brake pedal up with one finger to check
the free play with a force of less than 2 lbs
(10 N, 1 kg).
If the free play is not within proper specifi-
cation, contact your SUBARU dealer. „
Checking the brake pedal re-
serve distance
1) More than 2.56 in (65 mm)
Depress the pedal with a force of approxi-
mately 66 lbs (294 N, 30 kg) and measure
the distance between the upper surface of
the pedal pad and the floor.
When the measurement is smaller than
the specification, or when the pedal does
not operate smoothly, contact with your
SUBARU dealer.

Clutch pedal (Manual trans-
mission vehicles)
Check the clutch pedal free play and re-
serve distance according to the mainte-
nance schedule in the “Warranty and
Maintenance Booklet”. „
Checking the clutch function
Check the clutch engagement and disen-
gagement.
1. With the engine idling, check that there
are no abnormal noises when the clutch
pedal is depressed, and that shifting into
1st or reverse feels smooth.
2. Start the vehicle by releasing the pedal
slowly to check that the engine and trans-
mission smoothly couple without any sign
of slippage. „
Checking the clutch pedal
free play
1) 0.16 – 0.51 in (4.0 – 13.0 mm)
Lightly press the clutch pedal down with
your finger until you feel resistance, and
check the free play.
If the free play is not within proper specifi-
cation, contact your SUBARU dealer. Replacement of brake pad and lining
The right front disc brake and the right rear
disc brake have audible wear indicators
on the brake pads. If the brake pads wear
close to their service limit, the wear indica- tor makes a very audible scraping noise
when the brake pedal is applied.
If you hear this scraping noise each time
1
B00323
If you continue to drive despite the
scraping noise from the audible
brake pad wear indicator, it will re-
sult in the need for costly brake ro-
tor repair or replacement.

Aluminum wheels
Aluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety. yWhen any of the wheels is removed and
replaced for tire rotation or to change a
flat, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose, tight-
en it to the specified torque.y Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.y Never let the wheel rub against sharp
protrusions or curbs.y Be sure to fit tire chains on uniformly
and completely around the tire, otherwise
the chains may scratch the wheel. y When wheel nuts, balance weights, or
the center cap is replaced, be sure to re-
place them with genuine SUBARU parts
designed for aluminum wheels.Windshield washer fluid
If you spray washer fluid on the windshield
but the supply of washer fluid appears to
diminish, check the level of washer fluid in the tank.
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could in-
terfere with brake caliper operation
and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of vehi-
cle control could lead to an acci-
dent.
Never use engine coolant as washer
fluid because it could cause paint
damage.
