BOOSTER OPERATION INSPECTION
There are two ways to perform this inspection, with and without a
tester. Ordinarily, it is possible to roughly determine its condition
without using a tester.
CHECK AIR TIGHTNESS
1) Start engine.
2) Stop engine after running for 1 to 2 minutes.
3) Depress brake pedal several times with the same load as in
ordinary braking and observe pedal travel. If pedal goes
down deep the first time but its travel decreases as it is
depressed the second and more times, air tightness is
obtained.
4) If pedal travel doesn’t change, air tightness isn’t obtained.
CHECK OPERATION
1) With engine stopped, depress brake pedal several times
with the same load and make sure that pedal travel doesn’t
change. NOTE:
For this check, make sure that no air is in hydraulic line.
1. 1st
2. 2nd
3. 3rd
NOTE:
If defective, inspect vacuum lines and sealing parts, and
replace any faulty part.When this has been done, repeat
the entire test.
1. 1st, 2nd, 3rd

5-12 BRAKES
2) Start engine while depressing brake pedal. If pedal travel
increases a little, operation is satisfactory. But no change in
pedal travel indicates malfunction.
CHECK AIR TIGHTNESS UNDER LOAD
1) With engine running, depress brake pedal. Then stop engine
while holding brake pedal depressed.
2) Hold brake pedal depressed for 30 seconds. If pedal height
does not change, condition is good. But it isn’t if pedal rises.
FLUID PRESSURE TEST (IF EQUIPPED WITH
LSPV)
Test procedure for LSPV assembly is as follows.
Before testing, confirm the following.
Fuel tank is filled with fuel fully.
Vehicle is equipped with spare tire, tools, jack and jack han-
dle.
H: Hold
H: Hold
T: 30 seconds

5-16 BRAKES
1) Fill master cylinder reservoir with brake fluid and keep at
least one-half full of fluid during bleeding operation.
2) Remove bleeder plug cap.
Attach a vinyl tube (1) to bleeder plug, and insert the other
end into container (2).
3) Depress brake pedal several times, and then while holding it
depressed, loosen bleeder plug about one-third to one-half
turn.
4) When fluid pressure in cylinder is almost depleted, retighten
bleeder plug.
5) Repeat this operation until there are no more air bubbles in
hydraulic line.
6) When bubbles stop, depress and hold brake pedal and
tighten bleeder plug.
Tightening torque
Front bleeder plug : 11.0 N·m (1.1 kg-m, 8.0 lb-ft)
Rear bleeder plug : 8.0 N·m (0.8 kg-m, 6.0 lb-ft)
7) Then attach bleeder plug cap.
8) After completing bleeding operation, apply fluid pressure to
pipe line and check for leakage.
9) Replenish fluid into reservoir up to specified level.
10) Check brake pedal for sponginess. If found spongy, repeat
entire procedure of bleeding.

BRAKE HOSE/PIPE
FRONT BRAKE HOSE/PIPE
REMOVAL
1) Raise and support vehicle properly. Remove tire and wheel.
2) Clean dirt and foreign material from both flexible hose end and pipe end fittings.
3) Remove brake flexible hose or pipe.
INSTALLATION
Reverse brake flexible hose installation procedure, noting the followings.
Make sure that steering wheel is in straight-forward position and flexible hose has not twist or kink.
Check to make sure that flexible hose doesn’t contact any part of suspension, both in extreme right and
extreme left turn conditions. If it does at any point, remove and correct. Fill and maintain brake fluid level in
reservoir.
Bleed brake system. Refer to “AIR BLEEDING OF BRAKE SYSTEM”.
Perform brake test and check installed part for fluid leakage. NOTE:
This operation is not necessary when removing pipes connecting master cylinder.

5-44 BRAKES
REAR BRAKE HOSE/PIPE
REMOVAL
1) Raise and support vehicle properly. Remove tire and wheel.
2) Clean dirt and foreign material from both flexible hose end and pipe end fittings.
3) Remove brake flexible hose or pipe.
INSTALLATION
Reverse brake flexible hose installation procedure, nothing the followings.
Fill and maintain brake fluid level in reservoir.
Bleed brake system. Refer to “AIR BLEEDING OF BRAKE SYSTEM”.
Perform brake test and check each installed part for fluid leakage.
Never reuse protector nut once removed. Be sure to use a new one.
Install clamps properly referring to figure below and tighten bolts.
When installing hose, make sure that it has no twist or kink.

BRAKES 5-49
INSTALLATION
1) Install LSPV assembly with spring to vehicle body.
2) Torque each bolt and nut (1) to specification as indicated
respectively in figure.
Special tool
(A) : 09950-78230 (10 x 11 mm)
Tightening torque
LSPV adjust nut (a) : 25 N·m (2.5 kg-m, 18.0 lb-ft)
Brake pipe flare nuts (b) : 16 N·m (1.6 kg-m, 11.5 lb-ft)
3) Fill reservoir with specified fluid and bleed air from brake
system.
4) After bleeding air, check that LSPV is installed properly
referring to following “INSPECTION & ADJUSTMENT”.
INSPECTION AND ADJUSTMENT
1) Confirm the following before inspection and adjustment.
Fuel tank is filled with fuel fully.
Vehicle is equipped with spare tire, tools, jack and jack han-
dle.
Vehicle is free from any other load.
Vehicle is placed on level floor.
2) Push up LSPV lever with finger till it stops and measure
length of coil spring (“a” in figure).
3) Spring length “a” should be as specified.
Spring length “a”
2WD : 144 mm (5.67 in.)
4WD : 148 mm (5.83 in.)
4) If it isn’t, adjust it to specification by changing spring position
as shown in figure. After adjustment, tighten nut (1) to speci-
fied torque.
Tightening torque
LSPV adjust nut (a) : 25 N·m (2.5 kg-m, 18.0 lb-ft)
5) Confirm fluid pressure referring to “Fluid Pressure Test”.

NOTE:
Check to make sure that LSPV body and brake pipe joints
are free from fluid leakage. Replace defective parts, if
any.
