INSPECTION AFTER INSTALLATION
1. Check the brake hoses and tubes for the following: no scratches; no twist and deformation; no interfer-
ence with other components when steering the steering wheel; no looseness at connections.
2. Depress the brake pedal with a force of 785N (80 kg, 177 lb) and hold down the pedal for approximately 5
seconds with the engine running. Check for any fluid leakage.
CAUTION:

REMOVAL
1. Remove brake master cylinder assembly. Refer to BR-25, "Exploded View".
CAUTION:
 Depress the brake pedal several times to release the vacuum pressure from the brake booster.
Then remove the master cylinder assembly.
 Never depress the brake pedal after the master cylinder assembly is removed.
 The piston of the master cylinder assembly is exposed. Never damage it when removing the
master cylinder.
 The piston may drop off when pulled out strongly. Never hold the piston. Hold the cylinder body
when handling the master cylinder assembly.
2. Remove vacuum hose from brake booster. Refer to BR-31, "
Exploded View".
3. Remove snap pin (1) and clevis pin (2) from inside vehicle.
4. Remove nuts on brake booster and brake pedal assembly.
CAUTION:
Hold the brake booster so as to avoid dropping out.
5. Remove brake tube bracket and fuel feed tube bracket.
6. Remove brake booster from dash panel in engine room side.
CAUTION:
Never deform or bend the brake tubes.
NOTE:
If removing brake booster is difficult, remove clevis from brake
booster.
INSTALLATION
Note the following, and installation is the reverse order of removal.
 Be careful not to damage brake booster stud bolt threads. If brake booster is tilted during installation, the
dash panel may damage the threads.
 Never deform or bend the brake tubes when installing the brake booster.
 Always use a new gasket between the brake booster.

Inspection and AdjustmentINFOID:0000000003811200
INSPECTION AFTER REMOVAL
Output Rod Length Inspection
1. With a handy vacuum pump, apply vacuum pressure of −66.7
kPa (−500 mmHg, −19.70 inHg, –0.667 bar) to the brake
booster.
2. Check the output rod length (A).
Input Rod Length Inspection
1. Loosen the lock nut (1) and adjust the input rod (2) to the speci-
fied length (B).
2. Tighten the lock nut to the specified torque.
INSPECTION AFTER INSTALLATION
Operation
Depress the brake pedal several times at 5-second intervals with the
engine stopped. Start the engine with the brake pedal fully
depressed. Check that the clearance between brake pedal and dash
lower pane decreases.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. This is a normal phenomenon due to
the brake system operation.

FUNCTION DIAGNOSIS
ABS
System DiagramINFOID:0000000003766722
System DescriptionINFOID:0000000003766723
 Anti-Lock Braking System detects wheel revolution while braking, electronically controls braking force, and
prevents wheel locking during sudden braking. It improves handling stability and maneuverability for avoid-
ing obstacles.
 Electrical system diagnosis by CONSULT-III is available.

WHEEL SENSOR
 Completely push in rubber grommets of strut bracket and body bracket until they lock when install-
ing wheel sensor so that the wheel sensor harness will not be twisted. Install grommet groove onto
bracket with orange line on the harness facing bracket opening (mounting hole). There should be no
twists in the harness when installed.

REAR WHEEL SENSOR : Removal and InstallationINFOID:0000000003766868
REMOVAL
Be careful with the following when removing sensor.
CAUTION:
 Do not twist sensor harness as much as possible, when removing it. Pull sensors out without pulling
sensor harness.
 Be careful to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before remov-
ing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor function.
INSTALLATION
Be careful with the following when installing wheel sensor. Tighten installation bolts to the specified torques.
Refer to BRC-58, "
REAR WHEEL SENSOR : Exploded View".
CAUTION:
When installing, make sure there is no foreign material such as iron chips on and in the mounting hole
of the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove any
foreign material and clean the mount.

 To remove brake tube, use a flare nut wrench to prevent flare nuts and brake tube from being dam-
aged. To install, use flare nut torque wrench.
 Do not apply excessive impact to ABS actuator and electric unit (control unit), such as dropping it.
 Do not remove and install actuator by holding harness.
 After work is completed, bleed air from brake tube. Refer to BR-10, "
Bleeding Brake System".
 After installing harness connector in the ABS actuator and electric unit (control unit), make sure
connector is securely locked.
Install ABS actuator and electric unit (control unit) as per the follow-
ing steps.
1. Temporarily tighten mounting bolt (1) because the bracket (2) is
temporarily being hold.
2. Tighten mounting bolt (3) while holding the bracket.
3. Tighten mounting bolts to the specified torque in the order of (4),
(1).
