Wheel (with Tire) Removal and InstallationS6RW0D2406003
Removal
CAUTION!
Never use heat to loosen tight wheel because
the application of heat to wheel causes the
wheel life shorter and the wheel bearing
damage.

1) Loosen wheel nuts by approximately 180° (half a
rotation).
2) Hoist vehicle.
3) Make sure that the vehicle will not fall off by trying to
move vehicle body in both ways.
4) Remove wheel nuts except one.
5) Support the wheel and/or tire not to drop the wheel
and then remove the nut left with the wheel.
Installation
For installation, reverse removal procedure, noting the
following.
• Wheel nuts must be tightened in sequence and to
specified torque to avoid bending wheel or brake disc
or drum as shown in the figure.
NOTE
Before installing wheels, remove any build-
up of corrosion on wheel mounting surface
and brake disc or drum mounting surface by
scraping and wire brushing. Installing wheels
without good metal-to-metal contact at
mounting surfaces can cause wheel bolts to
loosen, which can later allow a wheel to
come off while vehicle is moving.

Tire Mounting and DismountingS6RW0D2406004
WARNING!
Do not stand over tire when inflating. Bead
may break when bead snaps over rim’s safety
hump and cause serious personal injury.
Do not exceed specified pressure when
inflating. If specified pressure will not seat
beads, deflate, re-lubricate and reinflate.
Over inflation may cause bead to break and
cause serious personal injury.

Use a tire changing machine to mount or dismount tires.
Follow equipment manufacturer’s instructions. Do not
use hand tools or tire irons alone to change tires as they
may damage tire beads or wheel rim.
Rim bead seats should be cleaned with a wire brush or
coarse steel wool to remove lubricants, old rubber and
light rust. Before mounting or dismounting a tire, bead
area should be well lubricated with approved tire
lubricant.
After mounting, inflate 330 kPa (47.9 psi) pressure so
that beads are completely seated. Then adjust pressure
to specified shown in the tire placard.
Tire RepairS6RW0D2406005
There are many different materials and techniques on
the market to repair tires. As not all of these work on all
types of tires, tire manufacturers have published detailed
instructions on how and when to repair tires. These
instructions can be obtained from each tire
manufacturer.

Diagnostic Information and Procedures
Brakes Diagnosis NoteS6RW0D4104001
Road Testing Brakes
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both light
and heavy pedal forces at various speeds to determine if
the vehicle stops evenly and effectively. Also drive
vehicle to see if it leads to one side or the other without
brake application. If it does, check the tire pressure, front
wheel alignment and front suspension attachments for
looseness. See diagnosis table for other causes.
Brake Fluid Leaks
Check the master cylinder fluid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low level indicates a leak in the
system. In such a case, check the entire brake system
for leakage. If even a slight evidence of leakage is noted,
the cause should be corrected or defective parts should
be replaced.Substandard or Contaminated Brake Fluid
Improper brake fluid, mineral oil or water in the fluid may
cause the brake fluid to boil or the rubber components
(piston cups and brake hoses) in the hydraulic system to
deteriorate.
If the above fluid is included in the system, replace the
master cylinder assembly and other rubber components
(hoses). The master cylinder assembly is disassemble
parts to maintain the performance.
The system must be flushed if there is any doubt as to
the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to
contaminated fluid.

1) Fill master cylinder reservoir with specified brake
fluid and keep at least one-half full of fluid during
bleeding operation.
Brake fluid
: Refer to reservoir cap
2) Remove bleeder plug cap. Attach a vinyl tube to
bleeder plug, and insert the other end into container.
3) Depress brake pedal several times, and then while
holding it depressed, loosen bleeder plug about one-
third to one-half turn.
4) When fluid pressure in cylinder is almost depleted,
retighten bleeder plug.
5) Repeat this operation until there are no more air
bubbles in hydraulic line.
6) When bubbles stop, depress and hold brake pedal
and tighten bleeder plug.
Tightening torque
Front brake caliper bleeder plug: 9 N·m (0.9 kgf-
m, 6.5 lb-ft)
Rear wheel cylinder bleeder plug: 8 N·m (0.8
kgf-m, 6.0 lb-ft)
7) Then attach bleeder plug cap.
8) After completing bleeding operation, apply fluid
pressure to pipe line and check for leakage.
9) Replenish fluid into reservoir up to specified level
referring to “Brake Fluid Level Inspection”.
10) Check brake pedal for sponginess. If found spongy,
repeat entire procedure of bleeding.
Front Brake Hose / Pipe Removal and
Installation
S6RW0D4106007
CAUTION!
Do not allow brake fluid to get on painted
surfaces. Painted surfaces will be damaged
by brake fluid, flush it with water immediately
if any fluid is spilled.

Removal
1) Raise and support vehicle properly. Remove tire and
wheel.
NOTE
This operation is not necessary when
removing pipes connecting master cylinder.

2) Clean dirt and foreign material from both flexible
hose end and pipe end fittings.
3) Drain brake fluid in reservoir.
4) Remove brake flexible hose or pipe.
Installation
Reverse brake flexible hose removal procedure, noting
the following.
• Make sure that steering wheel is in straight-forward
position and flexible hose has not twist or kink.
• Install clamps and tighten nuts referring to “Front
Brake Hose / Pipe Construction”.
• Install brake flexible hose (1) to caliper as shown in
figure.

Precautions for Steering DiagnosisS6RW0D6100001
Since the problems in steering involve several systems, they must all be considered when diagnosing a complaint. To
avoid using the wrong symptom, always road test the vehicle first. Proceed with the following preliminary inspection
and correct any defects which are found.
1) Inspect tires for proper pressure and uneven wear.
2) Raise vehicle on a hoist and inspect steering system for loose or damaged parts.
3) Spin front wheels. Inspect for out-of-round tires, out-of-balance tires, bent rims, loosen and/or rough wheel
bearings.
