POWER STEERING (P/S) SYSTEM 3B1-3
Hydraulic Pressure in P/S Circuit
Hydraulic pressure check
1) After cleaning joint of high pressure hose and P/S pump
thoroughly, disconnect hose from pump and install special
tool (oil pressure gauge, attachment and hose).
Special tool
(A) : 09915-77410
(B) : 09915-77420
2) Check each connection for fluid leakage and bleed air.
Refer to “AIR BLEEDING PROCEDURE” in this section.
3) With engine idling, turn steering wheel and warm up engine
till temperature of fluid in P/S fluid reservoir rises to 50 –
60°C (122 – 140°F).
4) Check back pressure by measuring hydraulic pressure with
engine idling and hands off steering wheel.
When back pressure is higher than specified values, check
control valve and piping for clogging.
Back pressure :
Lower than 1000 kPa (10 kg/cm
2, 142 psi) CAUTION:
Take care not to cause damage to A/C condenser during
service operation, if equipped.
1. P/S fluid reservoir
2. Attachment
3. Gasket
4. Union bolt
5. High pressure side
6. Low pressure side
1. P/S fluid reservoir 4. P/S gear box
2. Gauge valve (open) 5. High pressure side
3. P/S pump 6. Low pressure side

BRAKES PIPE/HOSE/MASTER CYLINDER 5A-7
Master Cylinder Assembly
REMOVAL
1) Disconnect reservoir lead wire (1) at coupler.
2) Clean around reservoir cap (2) and take out fluid with
syringe or such.
3) Disconnect brake pipes from master cylinder (3) and ABS
actuator (4).
INSPECTION
Inspect distance “A” to be the following.
Distance “A” :
57.4 mm (2.26 in) or more
If measurement is out of above specification, replace master cyl-
inder assembly.
INSTALLATION
1) Install master cylinder to brake booster.
2) Tighten master cylinder attaching nuts to specified torque.
Tightening torque
Master cylinder attaching nut (b) :
13 N·m (1.3 kg-m, 9.5 lb-ft)
3) Connect hydraulic lines to master cylinder and ABS actuator
and tighten flare nuts to specified torque.
Tightening torque
Brake pipe flare nut (c) : 16 N·m (1.6 kg-m, 12.0 lb-ft)
4) Connect reservoir lead wire (1).
5) Fill reservoir with specified brake fluid.
6) After installing, check brake pedal play and bleed air from
system (Refer to “BRAKE PEDAL PLAY CHECK” and
“BLEEDING BRAKE” in Section 5).
7) Perform brake test and check each installed part for fluid
leakage. NOTE:
Do not allow brake fluid to get on painted surfaces.
