Brake Line
18.Brake Line
A: INSPECTION
1. BRAKE LINE
1) Check scratches, swelling, corrosion, traces of
fluid leakage on the brake hoses or pipe joints.
2) Check the possibility of adjacent parts interfering
with brake pipes or hoses during driving, and loose
connections or clamps.
3) Check any trace of fluid leakage, scratches, etc.
on the master cylinder, wheel cylinder and pres-
sure control valve.
NOTE:
 When the brake fluid level in the reservoir tank is
lower than the specified limit, the brake fluid warn-
ing light on the combination meter will come on.
 Visually check the brake hose (using a mirror
where it is difficult to see) for any damage.
B: CHECKING
1. SERVICE BRAKE
1) Check the free play of brake pedal with a force of
less than 10 N (1 kgf, 2 lb).
Brake pedal free play:
0.5 — 2.0 mm (0.02 — 0.08 in)
2) If the free play is out of specifications above, ad-
just the brake pedal as follows.
(1) Be sure the engine is off. (No vacuum is ap-
plied to brake booster.)
(2) There should be play between brake boost-
er clevis and pin at brake pedal installing por-
tion.
[Depress brake pedal pad with a force of less
than 10 N (1 kgf, 2 lb) to a stroke of 0.5 to 2.0
mm (0.02 to 0.08 in).]
(3) Depress the surface of brake pad by hand.

(4) If there is no free play between clevis pin
and clevis, turn the brake switch adjusting nut
until the clearance between stopper and screw
of brake switch becomes 0.3 mm (0.012 in).
3) Check the pedal stroke.
While the engine is idling, depress the brake pedal
with a 490 N (50 kgf, 110 lb) load and measure the
distance between brake pedal and steering wheel.
With the brake pedal released, measure the dis-
tance between pedal and steering wheel again.
The difference between the two measurements
must be less than specified value. If the distance is
more than specified value, there is possibility of air
inside the hydraulic unit.
Brake pedal reserve distance: A
For Australia model
105 mm (4.13 in)/ 490 N (50 kgf , 110 lb) or less
Except for Australia model
90 mm (3.54 in)/ 490 N (50 kgf , 110 lb) or less4) Check to see if air is in the hydraulic brake line
by the feel of pedal operation. If air appears to exist
in the line, bleed it from the system.
5) Check for even operation of all brakes, using a
brake tester or by driving the vehicle for a short dis-
tance on a straight road.
2. BRAKE SERVO SYSTEM
1) With the engine off, depress the brake pedal
several times applying the same pedal force: Make
sure the travel distance should not change.
2) With the brake pedal depressed, start the en-
gine: Make sure the pedal should move slightly to-
ward the floor.
3) With the brake pedal depressed, stop the engine
and keep the pedal depressed for 30 seconds:
Make sure the pedal height should not change.
4) Check valve is built into the vacuum hose. Dis-
connect the vacuum hose to inspect function of
check valve.
Blow air into the vacuum hose from its brake boost-
er side end: Air must flow out of engine side end of
hose. Next blow air into the hose from engine side:
Air should not to brake booster side.
Replace both check valve and vacuum hose if the
check valve is faulty. Engine side of vacuum hose
is indicated by marking “ENG” as shown in illustra-
tion.
5) Check the vacuum hose for cracks or other dam-
age.
CAUTION:
When installing the vacuum hose on the engine
and brake booster, do not use soapy water or
lubricating oil on their connections.
6) Check vacuum hose to make sure it is tight and
secure.

1) Before checking idle speed, check the following:
(1) Ensure the air cleaner element is free from
clogging, ignition timing is correct, spark plugs
are in good condition, and the hoses are con-
nected properly.
(2) Ensure the malfunction indicator light does
not illuminate.
2) Warm-up the engine.
3) Stop the engine, and then turn the ignition switch
to OFF.
4) When using the Subaru Select Monitor, refer to
the following. TOOL, PREPARATION TOOL, General Descrip-
tion.>
(1) Insert the cartridge to Subaru Select Moni-
tor.
(2) Connect the Subaru Select Monitor to data
link connector.
(3) Turn the ignition switch to ON, and Subaru
Select Monitor switch to ON.
(4) Select the {Each System Check} in Main
Menu.
(5) Select the {Engine Control System} in Se-
lection Menu.
(6) Select the {Current Data Display & Save} in
Engine Control System Diagnosis.
(7) Select the {Data Display} in Data Display
Menu.
(8) Start the engine, and then read the engine
idle speed.
5) When using the tachometer (Secondary pick-up
type).
(1) Attach the pick-up clip to No. 1 cylinder
spark plug cord.(2) Start the engine, and then read the engine
idle speed.
NOTE:
 When using the OBD-II general scan tool, care-
fully read its operation manual.
 This ignition system provides simultaneous igni-
tion for #1 and #2 plugs. It must be noted that some
tachometers may register twice that of actual en-
gine speed.
6) Check the idle speed when unloaded. (With
headlights, heater fan, rear defroster, radiator fan,
air conditioning, etc. OFF)
Idle speed [No load and gears in “N” or “P”
range]:
650
±100 rpm
7) Check the idle speed when loaded. (Turn the air
conditioning switch to “ON” and operate the com-
pressor for at least 1 minute before measurement.)
Idle speed [A/C “ON”, no load and gears in “N”
or “P” range]:
850
±100 rpm
NOTE:
Idle speed can not be adjusted manually, because
the idle speed is automatically adjusted.
If the specified idle speed can not be maintained,
refer to General On-board Diagnosis Table under
“Engine Control System”. Basic Diagnostics Procedure.>

sion, check to be sure no work has been over-
looked. Doing this is very important in order to
facilitate re-installation and because the trans-
mission lowers under its own weight.
