from being damaged. To install, use su itable tool (flare nut torque wrench).
• Do not apply excessive impact to ABS actuator and elect ric unit (control unit), such as by dropping
it.
• Do not remove and install ABS actuator and el ectric unit (control unit) by holding harness.
• After work is completed, bleed air from brake tubes. Refer to BR-14, "Bleeding Brake System"
.
• After installing harness connector on the ABS act uator and electric unit (control unit), make sure
connector is securely locked.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.

CHASSIS AND BODY MAINTENANCE
1. Make sure no foreign material is in the reservoir, and refill withnew brake fluid.
CAUTION:
Do not reuse drained brake fluid.
2. Refill the brake system as follows: • Depress the brake pedal.
• Loosen bleeder valve.
• Slowly depress brake pedal to 2/3 of the brake pedal full stroke.
• Tighten bleeder valve.
• Release brake pedal.
Repeat this operation at intervals of two or three seconds until
all old brake fluid is discharged. Add new brake flui d to master cylinder reservoir sub tank frequently.
CAUTION:
Do not allow master cylinder reservoir to empt y as this may cause damage to master cylinder
internal components.
3. Bleed the air out of the brake hydraulic system. Refer to BR-14, "Bleeding Brake System"

RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal be fore starting the following procedure.
1. Connect the Tool between oil pump discharge connector and high-pressure hose. Bleed air from the hydraulic circuit while
opening valve fully. Refer to ST-30, "Air Bleeding Hydraulic Sys-
tem".
2. Start engine. Run engine until power steering fluid temperature reaches 50 ° - 80 °C (122 ° - 176 °F).
CAUTION:
• Leave the valve of the hydraulic pressure gauge fully open while starting and ru nning engine. If engine is
started with the valve closed, th e hydraulic pressure in oil
pump goes up to the relief pressure along with unusual
increase of fluid temperature.
• Be sure to keep hose clear of belts and other parts when engine is started.
3. Fully close the Tool valve with engine at idle and measure the relief oil pressure.
CAUTION:
Do not keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Replace oil pump if the relief oil pressure is outside the standard.
5. After inspection, disconnect the Tool from hydraul ic circuit, then add fluid and bleed air. Refer to ST-30,
"Air Bleeding Hydraulic System".

Draining and RefillingINFOID:0000000009461266
DRAINING
1. Disconnect the high and low pressure piping from power steering gear.
2. Drain power steering fluid into a suitable container.
REFILLING
1. Fill power steering reservoir while checking power steering fluid level.
2. Bleed air from power steering hydraulic system. Refer to ST-30, "Air Bleeding Hydraulic System"
.
3. Check for power steering fluid leaks.
Air Bleeding Hydraulic SystemINFOID:0000000009461267
AIR BLEEDING HYDRAULIC SYSTEM
If air bleeding is not complete, excessive noise in the power steering oil pump will be present.
1. Make sure engine is off.
2. Turn the steering wheel from the full right stop pos ition and then to full left stop position several times.
Repeat until bubbles are no longer being generated in the reservoir.
3. When the power steering fluid level lowers, refill the reservoir. CAUTION:
Do not allow the power steerin g fluid level to drop below
the hatching area.
4. Repeat steps one and two until the power steering fluid level stabilizes.
5. Start the engine and run at idle.
6. Turn the steering wheel from the full right stop pos ition and then to full left stop position several times.
Repeat until bubbles or fluid discoloration are no longer being generated in the reservoir.
7. When the power steering fluid level lowers, refill the reservoir.
8. Stop the engine.
9. Verify proper power steering fluid level. Power steering fluid level should be between the hatching area of the indicator on
the power steering reservoir tank cap.
