A: REMOVAL
1) Remove or disconnect the following parts in the
engine compartment.
(1) Remove the brake master cylinder.
(2) Disconnect the vacuum hose from brake
booster.
2) Remove the following parts from the pedal
bracket.
(1) Snap pin and clevis pin
(2) Four brake booster installation nuts
3) Remove the brake booster while avoiding the
brake pipe.
NOTE:
•Make sure that the booster shell and vacuum
pipe are not subject to strong impacts.
•Be careful not to drop the brake booster. If the
booster is dropped, replace it.
•Use special care when handling the operating
rod. If excessive force is applied to the operating
rod, the angle may change by ±3°, and it may result
in damage to power piston cylinder.
•Be careful when placing the brake booster on
floor.
•Do not change the push rod length.
CAUTION:
•Do not disassemble the brake booster.
•If external force is applied from above when
brake booster is placed in this position, the res-
in portion as indicated by “P” may become
damaged.

BRAKE
Air tightness check
Start the engine, and idle it for 1 to 2 minutes, then
turn it OFF. Depress the brake pedal several times
applying the normal pedal force. The pedal stroke
should be the longest at the 1st depression, and it
should become shorter at each successive depres-
sion. If no change occurs in the pedal height when
pressed, the brake booster is faulty.
NOTE:
•In case of defective operation, inspect the condi-
tion of the check valve and vacuum hose as well.
•Replace them if faulty, and perform the test
again.
•If the defective condition is not improved, check
accurately using a gauge.
Operation check
1) While the engine is OFF, depress the brake ped-
al several times applying the same pedal force, to
check for a change in pedal height.
2) With the brake pedal pressed, start the engine.
3) As the engine starts, the brake pedal should
move slowly toward the floor. If the pedal height
does not change, the brake booster is faulty.
NOTE:
If faulty, perform an accurate check with a gauge.
Loaded air tightness check
Depress the brake pedal while the engine is run-
ning, and turn the engine OFF while the pedal is de-
pressed. Keep the pedal depressed for 30
seconds. If the pedal height does not change, the
function of brake booster is normal. If the pedal
height increases, it is faulty.
NOTE:
If faulty, perform an accurate check with a gauge.
2. OPERATION CHECK (WITH GAUGE)
CAUTION:
When checking operation, be sure to apply the
parking brake securely.
Check with gauge
Connect the gauge as shown in the figure. After
bleeding air from the pressure gauge, perform the
checks.

Air tightness check
1) Start the engine and keep it running until vacu-
um pressure indicates point A of the vacuum gage
= 66. 7 kPa (500 mmHg, 19. 69 inHg). Do not de-
press the brake pedal at this time.
2) Stop the engine and check the gauge. If the vac-
uum pressure drop within 15 seconds after stop-
ping the engine is less than 3. 3 kPa (25 mmHg, 0.
98 inHg), the function of brake booster is normal.
If faulty, the cause may be one of the following.
•Check valve malfunction
•Leak from vacuum hose
•Leak from shell joint section or stud bolt welded
section
•Damaged diaphragm
•Leak from valve body seal and bearing section
•Leak from plate and seal assembly section
•Leak from poppet valve assembly section
Loaded air tightness check
1) Start the engine and depress the brake pedal
with a pedal force of 196 N (20 kgf, 44 lb). Keep the
engine running and keep the pedal pressed until a
vacuum of point B = 66. 7 kPa (500 mmHg, 19. 69
inHg) is indicated on the vacuum gauge.
2) Stop the engine and check the vacuum gauge.
If the vacuum pressure drop within 15 seconds af-
ter stopping the engine is less than 3.3 kPa (25
mmHg, 0.98 inHg), the function of brake booster is
normal.
If defective, refer to “AIR TIGHTNESS CHECK”.

3) If the brake booster is faulty, replace the it with a
new part.
Lack of boost action check
Turn the engine OFF, and set the value of the vac-
uum gauge to “0”. Then, check the fluid pressure
when the brake pedal is depressed. The pressure
must be greater than the specification listed.
Boosting action check
Set the vacuum gauge reading to 66. 7 kPa (500
mmHg, 19. 69 inHg) with the engine running. Then,
check the fluid pressure when the brake pedal is
depressed. The pressure must be greater than the
specification listed.

10) Check the pedal stroke.
Run the engine at idle after warming up the engine,
and depress the brake pedal with a force of 500 N
(51 kgf, 112 lb). Measure the distance between the
brake pedal and steering wheel. Release the pedal,
and measure the distance between pedal and
steering wheel again.
Specification of pedal stroke:
When depressing the pedal with a force of
500 N (51 kgf, 112 lb).
Less than 115 mm (4.53 in)
11) If the distance is more than specification, there
is a possibility of air being caught in the brake line.
Bleed the brake line of all air until the pedal stroke
meets the specification.
12) Operate the hydraulic control unit in the se-
quence control mode. quence Control.>
13) Check the pedal stroke again.
14) If the distance is more than specification, there
is a possibility of air being caught in the hydraulic
unit. Repeat above steps 2) to 9) until the pedal
stroke meets the specification.
15) Fill brake fluid up to the “MAX” level of the res-
ervoir tank.
16) Test run the vehicle and ensure that the brakes
operate normally.
