2006 SUBARU IMPREZA brake

11-28 Maintenance and service
Clutch pedal (MT 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
you apply the brake pedal, have the brake
pads serviced by your SUBARU dealer as
soon as possible.

Breaking-in of new brake
pads and linings
When replacing the brake pad or lining,
use only genuine SUBARU parts. After re-
placement, the new parts must be broken
in 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 approx-
imately 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 lbs [147 N, 15
kg].)
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 / 44 lbs (196 N, 20 kg)
Parking brake stroke
Check the parking brake stroke according
to the maintenance schedule in the “War-
ranty and Maintenance Booklet ”. When
the parking brake is properly adjusted,
braking power is fully applied by pulling
the lever up seven to eight notches gently
but firmly (approximately 44 lbs [196 N, 20
kg]). If the parking brake lever stroke is not
within the specified range, have the brake
system checked and adjusted at your
SUBARU dealer.
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.
A safe location and situation should
be selected for break-in driving.
Pulling the parking brake lever too
forcefully may cause the rear
wheels to lock. To avoid this, be cer-
tain to pull the lever up slowly and
gently.

placard and to have a speed symbol and
load index matching those shown on the
tire placard.
Using tires of a non-specified size detracts
from controllability, ride comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incor-
rect body-to-tire clearances and inappro-
priately changes the vehicle ’s ground
clearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern), con-
struction, and size. You are advised to re-
place the tires with new ones that are
identical to those fitted as standard equip-
ment.
For safe vehicle operation, SUBARU rec-
ommends replacing all four tires at the
same time.
Wheel replacement
When replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available
from SUBARU dealers.
NOTE
When any of the wheels is removed
and replaced for tire rotation or to
change a flat tire, always check the
tightness of the wheel nuts after driv-
ing approximately 600 miles (1,000
km). If any nut is loose, tighten it to the
specified torque.
All four tires must be the same in
terms of manufacturer, brand
(tread pattern), construction, de-
gree of wear, speed symbol, load
index and size. Mixing tires of dif-
ferent types, sizes or degrees of
wear can result in damage to vehi-
cle ’s power train. Use of different
types or sizes of tires can also
dangerously reduce controllabili-
ty and braking performance and
can lead to an accident.
Use only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires. Do-
ing so can dangerously reduce
controllability, resulting in an ac-
cident.
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.

Headlights (WRX-STI)
Replace any bulb only with a new
bulb of the specified wattage. Using
a bulb of different wattage could re-
sult in a fire.
High-intensity-discharge (HID)
bulbs are used for the low beams of
the headlights on the WRX-STI.
These HID bulbs use an extremely
high voltage. To avoid the risk of an
electric shock and resulting serious
injury, you should not attempt to re-
place them. Neither should you at-
tempt to replace the high-beam
bulbs, remove/refit the headlight as-
semblies, or remove any headlight-
assembly components. For replace-
ment of the headlight bulbs (low-
beam and high-beam), removal and
installation of the headlight assem-
blies, and removal of headlight-as-
sembly components, contact your
SUBARU dealer.
