PERIODIC MAINTENANCE SERVICES
16.Parking Brake
A: INSPECTION
Inspect the brake linings and disc rotor of both
sides of the rear brake at the same time by remov-
ing disc rotor.
1) Inspect the brake shoes for damage or deforma-
tion and check the brake linings for wear.
NOTE:
Always replace both primary and secondary brake
shoes for the left and right wheels at the same time.
Thickness of brake lining (except for back metal):
Standard: 4.0 mm (0.157 in)
Wear limit: 1.5 mm (0.059 in)
2) Check the inside of disk rotor for wear, dents or
other damage. If the inside surface of dick rotor is
streaked, correct the surface with emery cloth
(#200 or more). If it is unevenly worn or tapered,
correct or replace it.
Brake drum inside diameter:
Standard: 210 mm (8.26 in)
Wear limit: 211 mm (8.30 in)
3) If the deformation or wear of back plate, shoe,
etc. is noticeable, replace them.
4) When the shoe return spring tension is exces-
sively weakened, replace it.
5) Check whether the parking brake pedal is at the
predetermined number of notches (5 to 6 notches).
B: ADJUSTMENT
1) Remove the rear tire and release the parking brake.
2) Remove the cover (rubber) installed on the disc rotor.
3) Turn the disc rotor so that the service hole is di-
rectly below.
4) Turn the adjuster toward arrow mark (upward)
until it is locked slightly, by using flat-tip screwdriver
as shown in the figure.
5) Turn back (downward) the adjuster several notch-
es until the brake pedal no longer has any drag.
6) Install the cover (rubber) in original position correctly.
7) Install the rear tires.
8) Adjust so that the parking brake pedal is at the
predetermined number of notches (5 to 6 notches).

4. Road Test
A: INSPECTION
1. GENERAL PRECAUTION
Road tests should be conducted to properly diag-
nose the condition of automatic transmission.
NOTE:
When performing the test, do not exceed posted
speed limit.
2. D RANGE SHIFT FUNCTION
Check shifting between 1st ←→ 2nd ←→ 3rd ←→
4th ←→ 5th while driving on normal city streets.
3. D RANGE SHIFT SHOCK
Check the shock level when shifting up during nor-
mal driving.
4. KICK–DOWN FUNCTION
Check kick–down for each gear. Check the shock
level during kick–down at the same time.
5. ENGINE BRAKE OPERATION
•Check the 4th gear engine brake when shifting
down from 5th to 4th range while driving in 5th gear
of manual mode [50 to 60 km/h (31 to 37 MPH)].
•Check the 3rd gear engine brake when shifting
down from 4th to 3rd range while driving in 4th gear
of manual mode [50 — 60 km/h (31 — 37 MPH)].
•Check the 2nd gear engine brake when shifting
down from 3rd to 2nd range while driving in 3rd
gear of manual mode [40 — 50 km/h (25 — 31
MPH)].
•Check the 1st gear engine brake when shifting
down from 2nd to 1st range while driving in 2nd
gear of manual mode [20 — 30 km/h (12 — 19
MPH)].
6. P RANGE OPERATION
Stop the vehicle on an uphill grade of 5% or more
and shift to the “P” range. Check that the vehicle
does not move when the parking brake is released.
7. NOISE AND VIBRATION
Check for noise and vibration while driving and dur-
ing shifting.
8. OIL LEAKAGE
After the driving test, inspect for oil leaks from the
transmission body.

Stall Test
AUTOMATIC TRANSMISSION
5. Stall Test
A: INSPECTION
NOTE:
The stall test is extremely important in diagnosing
the condition of an automatic transmission and en-
gine. It should be conducted to measure the engine
stall speeds in “R” and “2nd of manual mode”.
Purposes of the stall test:
•Operational check of the automatic transmission
clutch
•Operational check of the torque converter clutch
•Engine performance check
1) Check that the throttle valve fully opens.
2) Check that the engine oil level is correct.
3) Check that the coolant level is correct.
4) Check that the ATF level is correct.
5) Check that the differential gear oil level is cor-
rect.
6) Raise the ATF temperature to 70 to 80°C (158 to
176°F) by driving a distance of 5 to 10 km (3 to 6
miles). Confirm the ATF temperature on Subaru
Select Monitor.
tor.>
7) Place the wheel chocks at the front and rear of
all wheels and apply the parking brake.
8) Move the select lever to ensure it operates prop-
erly, and then set to the “2nd gear of manual
mode”.
9) While stepping hard on the brake pedal, gradu-
ally step on the accelerator pedal.
10) When the engine speed is stabilized, quickly
record the engine speed and release accelerator
pedal.
11) Shift the select lever to “N” range, and cool
down the engine by idling it for more than one
minute.
12) Perform the procedure for “R” range in the
same way as “2nd on manual mode”.
NOTE:
•Do not continue the stall test for MORE THAN
FIVE SECONDS at a time (from fully closed throttle
to fully open throttle until stall speed reading). Do-
ing so will make the engine oil and ATF deteriorate
and the clutch and brake to be adversely affected.
•After performing the stall test, be sure to cool
down the engine for at least one minute with the se-
lect lever set in “P” or “N” range, and at an idle
speed of 1,200 rpm or less.
•If the stall speed is higher than the specified
range, attempt to finish the stall test in as short a
time as possible, in order to prevent the automatic
transmission from sustaining damage.
Stall speed (at sea level):
2,300 — 2,800 rpm
