Checking Brake Fluid LevelNJBR0006+Check fluid level in reservoir tank. It should be between Max
and Min lines on reservoir tank.
+If fluid level is extremely low, check brake system for leaks.
+Release parking brake lever and see if brake warning lamp
goes off. If not, check brake system for leaks.
SBR389C
Checking Brake LineNJBR0007CAUTION:
If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
1. Check brake lines (tubes and hoses) for cracks, deterioration
or other damage. Replace any damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
SBR419C
Changing Brake FluidNJBR0008CAUTION:
+Refill with new brake fluid ªDOT 4º.
+Always keep fluid level higher than minimum line on res-
ervoir tank.
+Never reuse drained brake fluid.
+Be careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.
1. Clean inside of reservoir tank, and refill with new brake fluid.
2. Connect a vinyl tube to each air bleeder valve.
3. Drain brake fluid from each air bleeder valve by depressing
brake pedal while keeping reservoir level higher than minimum
line by adding new brake fluid.
4. Repeat until new brake fluid comes out of each air bleeder
valve.
Use same procedure as in bleeding hydraulic system to refill
brake fluid. Refer to ªBleeding Brake Systemº, BR-8.
Brake Burnishing ProcedureNJBR0036Burnish the brake contact surfaces according to the following pro-
cedure after refinishing or replacing drums or rotors, after replac-
ing pads or linings, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic con-
ditions. Use extreme caution.
1. Drive the vehicle on a straight smooth road at 50 km/h (31
MPH).
2. Use medium brake pedal/foot effort to bring the vehicle to a
complete stop from 50 km/h (31 MPH). Adjust brake pedal/foot

Clean brake pads with a vacuum dust collector to minimize the
hazard of airborne particles or other materials.
Remove torque member fixing bolts and connecting bolt.
It is not necessary to remove connecting bolt except for dis-
assembly or replacement of caliper assembly. In this case,
suspend caliper assembly with wire so as not to stretch brake
hose.

Checking Fluid LevelNJST0012Check fluid level, referring to the scale on reservoir tank.
Use ªHOTº range for fluid temperatures of 50 to 80ÉC (122 to
176ÉF).
Use ªCOLDº range for fluid temperatures of 0 to 30ÉC (32 to 86ÉF).
CAUTION:
+Do not overfill.
+Recommended fluid is DEXRON
TMIII or equivalent. Refer
to MA-20, ªFluids and Lubricantsº.
YST006
YST007
Checking Fluid LeakageNJST0013Check the lines for improper attachment and for leaks, cracks,
damage, loose connections, chafing and deterioration.
1. Run engine between idle speed and 1,000 rpm.
Make sure temperature of fluid in oil tank rises to 60 to 80ÉC
(140 to 176ÉF).
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each ªlockº position for five seconds
and carefully check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
4. If fluid leakage at connectors is noticed, loosen flare nut and
then retighten.
Do not overtighten connector as this can damage O-ring,
washer and connector.
5. If fluid leakage from power steering pump is noticed, check
power steering pump. Refer to ST-25.
6. Check rack boots for accumulation of power steering fluid.

Bleeding Hydraulic SystemNJST00141. Raise front end of vehicle until wheels are clear of the ground.
2. Add fluid into oil tank to specified level. Then quickly turn steer-
ing wheel fully to right and left and lightly touch steering stop-
pers.
Repeat steering wheel operation until fluid level no longer
decreases.
3. Start engine.
Repeat step 2. above.
+Incomplete air bleeding will cause the following to occur. When
this happens, bleed air again.
a) Air bubbles in reservoir tank
b) Clicking noise in oil pump
c) Excessive buzzing in oil pump
Fluid noise may occur in the valve or oil pump. This is common
when the vehicle is stationary or while turning the steering wheel
slowly. This does not affect the performance or durability of the
system.

SST090B
Checking Steering Wheel Turning ForceNJST00151. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-
ture. [Make sure temperature of fluid is approximately 60 to
80ÉC (140 to 176ÉF).]
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360É from the neutral position.
Steering wheel turning force:
39 N (4 kg, 9 lb) or less
5. If steering wheel turning force is out of specification, check
rack sliding force.
a. Disconnect steering column lower joint and knuckle arms from
the gear.
b. Start and run engine at idle to make sure steering fluid has
reached normal operating temperature.
c. Pull tie-rod slowly to move it from neutral position to±11.5 mm
(±0.453 in) at speed of 3.5 mm (0.138 in)/s. Check that rack
sliding force is within specification.
Average rack sliding force:
132 - 308 N (13.5 - 31.4 kg, 30 - 69 lb)
Maximum force deviation:
176 N (17.9 kg, 39 lb)
6. If rack sliding force is not within specification, overhaul steer-
ing gear assembly.
7. If rack sliding force is OK, inspect steering column. Refer to
ST-13.
