Removal and InstallationEDS000ZX
REMOVAL
1. Put mating marks onto propeller shaft flange yoke and final drive and transfer companion flanges.
CAUTION:
Use paint to avoid scratching the surface.
2. Remove mounting nuts and remove exhaust tube insulator from vehicle.
3. Loosen mounting nuts of center bearing mount brackets.
CAUTION:
Tighten nuts temporarily.
4. Remove mounting nuts and bolts from propeller shaft companion flanges, transfer, and final drive.
Remove mounting nuts securing center bearing brackets onto vehicle. Then remove propeller shaft from
vehicle.
CAUTION:
If constant velocity joint was bent during propeller shaft assembly removal, installation, or trans-
portation, its boot may be damaged. Wrap boot interference area to metal part with shop cloth or
rubber to protect boot from breakage.
INSPECTION AFTER REMOVAL
1. As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft
assembly.
2. Check propeller shaft for bend and damage. If damage is
detected, replace propeller shaft assembly.
3. Check center bearing for abnormal noise and damage. If noise
or damage is detected, replace propeller shaft assembly.
CAUTION:
● Center bearings (front and rear) cannot be disassem-
bled.
● Joints cannot be disassembled.

LOOSENESS, BACKLASH AND DAMAGE OF MOUNTING PARTS AND CONNECTIONS
Lift vehicle and inspect the following:
●Check mounting point of each component for looseness, backlash and damage.
●Check lower ball joint end play.
1. Attach a dial gauge so that the contact rests on the brake caliper.
2. Set front wheels in a straight-ahead position. Do not depress brake pedal.
3. Measure axial endplay by placing an iron pry bar or something similar between transverse link and steer-
ing knuckle.
CAUTION:
Be careful not to damage ball joint boot.
4. If axial endplay is outside the standard, remove transverse link and check lower ball joint.
Wheel AlignmentEES00073
DESCRIPTION
●Measure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, coolant, and
lubricant are full. However, spare tire, jack, and hand tools should be unloaded.
PRELIMINARY INSPECTION
1. Check the tires for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial endplay.
4. Check lower ball joint axial endplay.
5. Check strut operation.
6. Check each mounting point of axle and suspension for looseness and deformation.
7. Check each link and arm for cracks, deformation, and other damage.
8. Check the vehicle posture.
INSPECTION OF CAMBER, CASTER, AND KINGPIN INCLINATION ANGLES
● Camber, caster, and kingpin inclination angles cannot be adjusted.
●Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so the vehicle will remain horizontal.
1. Measure camber, caster and kingpin inclination of both right and
left wheels with a suitable alignment gauge.
2. If camber, caster or kingpin inclination is not within specification,
inspect front suspension parts. Replace dam-aged or worn out
parts.

WARNING:
●Clean brake pads with a vacuum dust collector to minimize the hazard of airborne particles or
other materials.
CAUTION:
●When cylinder body is open, do not depress brake pedal because piston will pop out.
●Be careful not to damage piston boot or get oil on rotor. Always replace shims when replacing
pads.
●If shims are rusted or show peeling of the rubber coat, replace them with new shims.
●It is not necessary to remove connecting bolt except for disassembly or replacement of caliper
assembly. In this case, suspend cylinder body with wire so as not to stretch brake hose.
●Burnish the brake contact surfaces after refinishing or replacing drums or rotors, after replacing
pads or linings, or if a soft pedal occurs at very low mileage. Refer to BR-10, "
Brake Burnishing
Procedure" .

INSTALLATION
CAUTION:
●Refill with new brake fluid “DOT 3” or “DOT 4”.
●Never reuse drained brake fluid.
1. Install disc rotor.
2. Install caliper assembly. Tighten mounting bolts to the specified torque.
CAUTION:
Before installing caliper assembly, wipe oil and grease on steering knuckle washer seats and cali-
per assembly mounting surface.
3. Connect brake hose to caliper assembly and tighten union bolts to the specified torque.
CAUTION:
●Do not reuse the copper washer for union bolts.
●Securely assemble brake hose to protrusions on cylinder body.
4. Bleed air. Refer to BR-10, "
Bleeding Brake System" .

WARNING:
Be careful not to pinch your fingers in the piston.
CAUTION:
Be careful not to damage the cylinder inner wall.

bolt mounting hole to remove pistons and piston boots.
2. Using flat-bladed screwdriver, remove piston seals.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Never use mineral oils such as gasoline or kerosene.
●Check cylinder inner wall for corrosion, wear and damage. If corrosion, wear or damage is detected,
replace the cylinder body.
●Minor flaws caused by corrosion or foreign material can be removed by polishing the surface with fine
sandpaper. Replace the cylinder body, if necessary.

Check piston surface for corrosion, wear and damage. If corrosion, wear or damage is detected, replace the
applicable part.
Sliding Pin, Pin Bolt, and Pin Boot
Check sliding pin and sliding pin boot for wear, damage and cracks. If corrosion, wear or damage is detected,
replace the applicable part.
DISC ROTOR INSPECTION
Visual Inspection
Check surface of the disc rotor for uneven wear, cracks and serious damage. If uneven wear, cracks or seri-
ous damage is detected, replace it.
Run Out Inspection
1. Using wheel nuts, fix the disc rotor to the wheels hub. (2 or more positions)
2. Using a dial indicator, check run out.
CAUTION:
Before measuring, make sure that the axle endplay is 0 mm
(0 in).
3. If the run out is outside the limit, find the minimum run out point
by shifting the mounting positions of the disc rotor and wheel hub by one hole.
Thickness Inspection
Using a micrometer, check thickness of the disc rotor. If the thick-
ness is outside the standard, replace the disc rotor.
ASSEMBLY
CAUTION:
When assembling, do not use rubber grease.
1. Apply rubber lubricant to piston seals, and install them to cylin-
der body.
CAUTION:

hand. Assemble piston side lip on piston boot properly into
groove on piston.
CAUTION:
Press piston evenly and change pressing point to prevent
cylinder inner wall from being rubbed.
BRAKE BURNISHING PROCEDURE
Burnish the brake contact surfaces according to the following procedure after refinishing or replacing drums or
rotors, after replacing pads or linings, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic conditions. 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 pressure such that vehicle stopping time equals 3 to 5 seconds.
3. To cool the brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.
4. Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.
