REAR SUSPENSION PARTSNJSU0029Check axle and suspension parts for excessive play, wear or dam-
age.
Shake each rear wheel to check for excessive play.
SSU036
Retighten all nuts and bolts to the specified torque.
Tightening torque:
Refer to “REAR SUSPENSION”, SU-17.
SMA113
Check shock absorber for oil leakage or other damage.
Check wheelarch height. Refer to “On-vehicle Service”,
“FRONT SUSPENSION PARTS”, SU-6.
REAR WHEEL ALIGNMENTNJSU0030Before checking rear wheel alignment, be sure to make a prelimi-
nary inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand
tools and mats in designated positions.
SFA975B
Preliminary InspectionNJSU0030S011. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage.
If deformed, remove wheel and check wheel runout.
a. Remove tire from wheel and mount wheel on a tire balance
machine.
b. Set dial indicator as shown in the illustration.
Wheel runout (Dial indicator value):
Refer to SDS, SU-15.
3. Check front wheel bearings for looseness.

Checking Brake Fluid LevelNJBR0006Check 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 “DOT 4”.
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 “Bleeding Brake System”, 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

RemovalNJBR0011CAUTION:
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.
All hoses must be free from excessive bending, twisting
and pulling.
For ball & ramp type rear caliper, care should be taken as
not to let air enter the body.
1. Remove flare nut connecting brake tube and hose, then with-
draw lock spring.

Dual Proportioning ValveNJBR0149INSPECTIONNJBR0149S01CAUTION:
Carefully monitor brake fluid level at master cylinder.
Use new brake fluid “DOT 4”.
Be careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
paint areas, wash it away with water immediately.
Depress pedal slowly when raising front brake pressure.
Check rear brake pressure at least 2 seconds after front
brake pressure reaches specified value.
1. Connect brake fluid pressure gauge to air bleeders of front and
rear brakes on either LH or RH side.
2. Bleed air from the tool.
3. Check fluid pressure by depressing brake pedal.
Unit: kPa (bar, kg/cm2, psi)
Applied pressure (Front brake) 5,884 (58.8, 60, 853.2)
Output pressure (Rear brake)3,430 - 4,800
(34.3 - 45, 35 - 45.70, 497 - 649.5)
If output pressure is out of specifications, replace the master
assembly (built-in type).
4. Bleed air after disconnecting the Tool. Refer to “Bleeding Brake
System”, BR-8.
REMOVAL AND INSTALLATION (BUILT-IN TYPE)NJBR0149S02Always replace together with master cylinder as an assembly.
Refer to “MASTER CYLINDER (NABCO)”, BR-14.
