Brake Line
(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.

(2) Retighten the adjusting screw to 7.4 N·m
(0.75 kgf-m, 5.4 ft-lb) and back off 25°.
(3) Apply Liquid gasket to at least 1/3 of entire
perimeter of adjusting screw thread.
(4) Install the lock nut. While holding the adjust-
ing screw with a wrench, tighten the lock nut us-
ing ST.
ST 926230000 SPANNER
Tightening torque (Lock nut):
39 N·m (4.0 kgf-m, 29 ft-lb)
Hold the adjusting screw with a wrench to pre-
vent it from turning it, while tightening the lock
nut.
4. TIE-ROD
1) Check the tie-rod and tie-rod ends for bends,
scratches or other damage.
2) Check the connections of knuckle ball joints for
play, inspect for damage on dust seals, and check
free play of ball studs. If the castle nut is loose, re-
tighten it to the specified torque, then tighten further
up to 60° until the cotter pin hole is aligned.
Tightening torque:
27 N·m (2.75 kgf-m, 19.9 ft-lb)3) Check the lock nut on tie-rod end for tightness. If
it is loose, retighten it to the specified torque.
Tightening torque:
83 N·m (8.5 kgf-m, 61.5 ft-lb)
5. POWER STEERING FLUID LEVEL
NOTE:
Check at power steering fluid temperature 20°C
(68°F); read the fluid level on the “COLD” side.
Check at power steering fluid temperature 80°C
(176°F); read the fluid level on the “HOT” side.
1) Place the vehicle with engine stopped on a flat
and level surface.
2) Check the fluid level using the scale on the out-
side of reservoir tank (A). If the level is below “MIN”
(B), add fluid to bring it up to “MAX” (C).
NOTE:
If the fluid level is at “MAX” level or above, drain flu-
id to keep the level in specified range of indicator by
using a syringe or the like.
Recommended fluid:
Dexron III
Fluid capacity:
0.72 (0.7 US qt, 0.6 Imp qt)
6. POWER STEERING FLUID FOR LEAKS
Inspect the underside of oil pump and gearbox for
power steering system, hoses, piping and their
couplings for fluid leaks.
If fluid leaks are found, correct them by retightening
their fitting bolts (or nuts) and/or replacing their
parts.
CAUTION:
Wipe the leakage fluid off after correcting flu-
id leaks, or a wrong diagnosis is taken later.
Also pay attention to clearances between
hoses (or pipings) and other parts when in-
specting fluid leaks.
(A) Apply Liquid gasket to at least 1/3 of entire
perimeter

7. HOSES OF OIL PUMP FOR DAMAGES
Check the pressure hose and return hose of oil
pump for crack, swell or damage. Replace the hose
with a new one if necessary.
CAUTION:
Prevent the hoses from revolving and/or turn-
ing when installing hoses.
8. POWER STEERING PIPES FOR DAM-
AGE
Check the power steering pipes for corrosion and
damage.
Replace the pipes with a new one if necessary.
9. GEARBOX BOOTS
Inspect both sides of gearbox boots as follows, and
correct the defects if necessary.
1) (A) and (B) positions of gearbox boot are fitted
correspondingly in (A) and (C) grooves of gearbox
and the rod (C).
2) Clips are fitted outside of (A) and (B) positions of
boot.
3) Boot does not have crack and hole.
NOTE:
Rotate (B) the position of gearbox boot against
twist of it produced by adjustment of toe-in, etc.
Apply grease to the groove (C).
10.FITTING BOLTS AND NUTS
Inspect the fitting bolts and nuts of oil pump and
bracket for looseness, and retighten them if neces-
sary.
NOTE:
Inspect or retighten them when engine is cold.
