REMOVAL SERVICE POINTS
AA"REAR BRAKE CALIPER REMOVAL
Suspend the rear brake caliper from the body with wire, etc.
to prevent it from falling.
Caution
If the vehicle is equipped with the Brembo disc brake, during
maintenance, take care not to contact the parts or tools to
the caliper because the paint of caliper will be scratched.
And if there is brake fluid on the caliper, wipe out quickly.
AB"DRIVE SHAFT NUT REMOVAL
Caution
Do not apply pressure to wheel bearing by the vehicle
weight to avoid possible damage to wheel bearing before
tightening drive shaft nut fully.
AC"REAR DRIVE SHAFT ASSEMBLY REMOVAL
1. Use the special tools to push out the drive shaft from
the hub.
2. Remove the drive shaft from the transmission by the
following procedure.
Insert a pry bar between the differential carrier and the
drive shaft, and then pry the drive shaft from the differential
carrier.
Caution
(1) Do not pull on the drive shaft; doing so will damage
the T.J.; be sure to use the pry bar.
(2) When pulling the drive shaft out from the
differential carrier, be careful that the spline part
of the drive shaft does not damage the oil seal.
(3) Do not apply the vehicle weight to the wheel
bearing while loosening the drive shaft nut.
Otherwise wheel bearing will be damaged. If,
however, the vehicle weight must be applied to
the bearing (because of moving the vehicle),
temporarily secure the wheel bearing by using
the special tool.

REMOVAL AND INSTALLATION
Caution
1. Before removing the steering wheel and air bag module assembly, always refer to GROUP
52B - Service Precautions, Air bag Module and Clock Spring. Also, set the front wheels so
that they are facing straight forward, and remove the ignition key. If you fail to do this, the
SRS clock spring will be damaged, causing the SRS air bag to be inoperative and serious
injury.
2. *
1: Indicates parts which should be initially tightened, and then fully tightened after placing
the vehicle horizontally and loading the full weight of the engine on the vehicle body.
3. *
2: Indicates parts which should be temporarily tightened, and then fully tightened with the
vehicle on the ground in the unladen condition.
Caution
If the vehicle is equipped the Brembo disc brake, during maintenance, take care not to contact
the parts or tools to the caliper because the paint of caliper will be scratched.

CHECK VALVE OPERATION CHECK
1. Remove the vacuum hose. (Refer to P.35A-17.)
Caution
The check valve should not be disassembled from
the vacuum hose as they are united as one part.
2. Check the operation of the check valve by using a vacuum
pump.
Vacuum pump
connectionAccept/reject criteria
Connection at the brake
booster side (A)A negative pressure (vacuum) is
created and held.
Connection at the intake
manifold side (B)A negative pressure (vacuum) is
not created.
Caution
If the check valve is defective, always replace it as
an assembly unit together with the vacuum hose.
PROPORTIONING VALVE FUNCTION TEST

Caution
The proportioning valves are installed independently for
the right and left brake lines. Always measure each valve.
1. Connect two pressure gauges to the output port of the
master cylinder and output port of the proportioning valve.
2. Bleed the brake line and the pressure gauges. (Refer
to P.35A-10.)
3. Depress the brake pedal gradually. Then check that the
split point, where the output fluid pressure begins to drop
in proportion to the output fluid pressure, is at the standard
value.
Standard value: 2.70 - 3.19 MPa
4. Depress the brake pedal more strongly than at the above
step. Then check that the output fluid pressure is at the
standard value when the input fluid pressure is 6.86 MPa.
Standard value: 3.68 - 4.17 MPa
5. Measure each output fluid pressure at both valves, and
check that the difference between the two is at the limit
value or less.
Limit: 0.49 MPa
6. If the measured pressure exceeds the limit, replace the
proportioning valve.

BLEEDING
Caution
Specified brake fluid: DOT3 or DOT4
Always use the specified brake fluid. Avoid using a
mixture of the specified brake fluid and other fluid.
MASTER CYLINDER BLEEDING
The master cylinder used has no check valve, so if bleeding
is carried out by the following procedure, bleeding of air from
the brake pipeline will become easier. (When brake fluid is
not contained in the master cylinder.)
1. Fill the reserve tank with brake fluid.
2. Keep the brake pedal depressed.
3. Have another person cover the master cylinder outlet
with a finger.
4. With the outlet still closed, release the brake pedal.
5. Repeat steps 2 - 4 three or four times to fill the inside
of the master cylinder with brake fluid.
BREMBO DISC BRAKE BLEEDING
Caution
Take care not to contact the parts or tools to the caliper
because the paint of caliper will be scratched. And if
there is brake fluid on the caliper, wipe out quickly.
Connect a vinyl tube to the outer end of the air bleeder screw
to bleed the circuit of air. Then, connect the vinyl tube to
the inner end and bleed the circuit of air. Except for these,
the conventional procedures shall be followed. After the circuit
has been bled of air, tighten both air bleeder screws securely.
BRAKE PIPE LINE BLEEDING
Bleed the air in the sequence shown in the figure.
