PLAY AND CLEARANCE BETWEEN THE BRAKE PEDAL AND FLOOR PANEL WITH PEDAL
DEPRESSED
1. Check the brake pedal free height from the dash lower panel (1).
2. Adjust the height referring to the following specifications.
ADJUSTMENT
1. Loosen the stop lamp switch and ASCD cancel switch by rotat-
ing it counterclockwise by 45°.
2. Loosen the lock nut (A) on the input rod, then rotate the input
rod to set the pedal to the specified height, and tighten the lock
nut (A) to the specified torque. Refer to BR-23, "
Components" .
CAUTION:
Check that the threaded end of the input rod stays inside
the clevis.
3. With the pedal pulled and held by hand, press the stop lamp
switch and ASCD cancel switch until its threaded end contacts
the stopper rubber.
4. With the threaded end of the stop lamp switch contacting the
stopper rubber and ASCD cancel switch, rotate the switch clock-
wise by 45° to secure.
CAUTION:
Make sure that the clearance “C” between the stopper rub-
ber and threaded end of the stop lamp switch and ASCD
cancel switch is within the standard.
5. Check the pedal play.

3. Attach the brake hose to the brake tube, partially tighten the
flare nut as far as possible by hand, then secure to the bracket
with the lock plate.
4. Using a flare nut crowfoot and torque wrench, tighten the flare nut to the specified torque.
5. Refill brake fluid and bleed air. Refer to BR-11, "
Bleeding Brake System" .
Inspection after InstallationNFS0000G
CAUTION:
If a leak is detected at the connections, retighten it or, if necessary, replace the damaged part.
1. Check hose, tube, and connections for fluid leaks, damage, twist, deformation, contact with other parts,
and loose connections.
2. While depressing pedal under a force of 785 N (80 kg, 177 lb) with engine running for approximately 5
seconds, check for fluid leakage from each part.: 16.7 – 19.6 N·m (1.7 – 1.9 kg-m, 13 – 14 ft-lb)
: 14.8 – 17.6 N·m (1.5 – 1.7 kg-m, 11 – 12 ft-lb)

BRAKE BOOSTERPFP:47200
On-Vehicle InspectionNFS0000L
OPERATING CHECK
With the engine stopped, change the vacuum to the atmospheric
pressure by depressing the brake pedal several times. Then with
brake pedal fully depressed, start the engine and when the vacuum
pressure reaches the standard, check that the clearance between
the brake pedal and floor panel decreases.
CAUTION:
Depressing pedal interval is approximately 5 seconds.
AIRTIGHT CHECK

Run the engine at idle for approximately 1 minute, and stop it
after applying vacuum to the booster. Depress the brake pedal
normally to change the vacuum to the atmospheric pressure.
Check that distance between the brake pedal and floor panel
gradually increases.

Depress brake pedal while engine is running, and stop engine
with pedal depressed. The pedal stroke should not change after
holding pedal down for 30 seconds.
CAUTION:
Depressing pedal interval is approximately 5 seconds.

Removal and InstallationNFS0000M
REMOVAL
CAUTION:

Be careful not to deform or bend brake piping while removing and installing the brake booster.

Replace clevis pin if it is damaged.

Be careful not to damage brake booster stud bolt threads. If brake booster is tilted or inclined dur-
ing installation, the dash panel may damage the threads.

Attach the check valve in the correct orientation.
1. Remove vacuum hose from the brake booster. Refer to BR-25, "
VACUUM LINES" .
2. Remove the brake master cylinder. Refer to BR-24, "
Removal and Installation" .
3. Remove the brake piping between brake master cylinder and ABS actuator and electric unit (control unit).
Refer to BR-12, "
Hydraulic Circuit" .
CAUTION:
For M/T vehicles with remove the brake piping after removing the clutch reservoir tank bolt.
4. Remove the brake pedal attachment snap pin and clevis pin from inside the vehicle.
5. Remove the nuts on the brake booster and brake pedal assembly.
6. Remove brake booster assembly from the engine compartment side.
INSPECTION AFTER REMOVAL
Output Rod Length Inspection
1. Using a handy vacuum pump, apply a vacuum of −66.7 kPa (−
500 mmHg,−19.69 inHg) to the brake booster.
2. Check output rod length.
INSTALLATION
1. Loosen the lock nut to adjust the input rod length so that the
length “B” (in the figure on the right) satisfies the specified value.
2. After adjusting “B”, temporarily tighten the lock nut to install the
booster assembly to the vehicle. At this time, make sure to
install a gasket between the booster assembly and the vehicle.
3. Connect the brake pedal with the clevis of the input rod.
4. Install the pedal bracket mounting nuts and tighten them to the
specified torque.
5. Install the brake piping between brake master cylinder and ABS
actuator and electric unit (control unit). Refer to BR-12, "
Hydraulic Circuit" .
6. Install the master cylinder to the booster assembly. Refer to BR-24, "
Removal and Installation" .
7. Adjust the height and play of the brake pedal. Refer to BR-7, "
ADJUSTMENT" .
8. Tighten the lock nut of the input rod to the specified torque. Refer to BR-23, "
Components" .
9. Refill new brake fluid and bleed air. Refer to BR-11, "
Bleeding Brake System" . Standard dimension when vacuum −66.7 kPa

CAUTION:

Because vacuum hose contains a check valve, it must be
installed in the correct orientation. Refer to the stamp or
label to confirm correct installation. The brake booster will
not operate normally if the hose is installed in the wrong
direction.

Insert the vacuum hose for at least 24 mm (0.94 in).

Do not use lubricating oil during assembly.
