Brake Fluid Level InspectionS6RW0D4106004
CAUTION!
Do not use shock absorber fluid or any other
fluid which contains mineral oil. Do not use a
container which has been used for mineral oil
or a container which is wet from water.
Mineral oil will cause swelling and distortion
of rubber parts in hydraulic brake system and
water mixed into brake fluid will lower fluid
boiling point. Keep all fluid containers
capped to prevent contamination.

NOTE
Be sure to use particular brake fluid either as
indicated on reservoir cap of that vehicle or
recommended in owner’s manual which
comes along with that vehicle. Use of any
other fluid is strictly prohibited.
Fluid level should be between MIN and MAX
lines marked on reservoir.
When brake warning light lights sometimes
during driving, replenish fluid to MAX level.
When fluid decreases quickly, inspect brake
system for leakage. Correct leaky points and
then refill to specified level.

1) Check master cylinder, reservoir and reservoir hose
(if equipped) for crack, damage and brake fluid
leakage. If any faulty condition exists, correct or
replace.
2) Check that brake fluid level is between MAX (1) and
MIN marks (2) on reservoir.
Brake Light Switch AdjustmentS6RW0D4106005
Adjustment should be made as follows. Pull up brake
pedal toward you and while holding it there, adjust
switch position so that clearance between end of thread
and brake pedal is as specified. Then lock it by turning
clockwise.
Clearance between brake pedal and brake light
switch
“a”: 0.5 – 1.5 mm (0.02 – 0.05 in.)
Air Bleeding of Brake SystemS6RW0D4106006
CAUTION!
Brake fluid is extremely damaging to paint. If
fluid should accidentally touch painted
surface, immediately wipe fluid from paint
and clean painted surface.

Bleeding operation is necessary to remove air whenever
it entered hydraulic brake system.
Hydraulic lines of brake system are based on the
diagonal split system. When a brake pipe or hose was
disconnected at the wheel, bleeding operation must be
performed at both ends of the line of the removed pipe or
hose. When any joint part of the master cylinder of other
joint part between the master cylinder and each brake
(wheel) was removed, the hydraulic brake system must
be bled at all 4 wheel brakes.
NOTE
Perform bleeding operation starting with rear
brake caliper or wheel cylinder farthest from
master cylinder and then at front caliper of
the same brake line. Do the same on the
other brake line.

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.

• Check to make sure that flexible hose doesn’t contact
any part of suspension, both in extreme right and
extreme left turn conditions. If it does at any point,
remove and correct. Fill and maintain brake fluid level
in reservoir.
• Bleed brake system. Refer to “Air Bleeding of Brake
System”.
• Perform brake test and check installed part for fluid
leakage.

• When installing hose, make sure that it has no twist or
kink.
Brake Hose and Pipe InspectionS6RW0D4106009
Hose
The brake hose assembly should be checked for road
hazard damage, for cracks and chafing of outer cover,
for leaks and blisters. A light and mirror may be needed
for an adequate inspection. If any above conditions are
observed on brake hose, it is necessary to replace it.
Pipe
Inspect the pipe for damage, cracks, dents and
corrosion. If any defect is found, replace it.

Inspect pad linings (1) periodically according to
maintenance schedule whenever wheels are removed
(for tire rotation or other reason). Take a look through
each end and inspection hole of caliper and check lining
thickness of outside and inside pads.
If lining is worn and its thickness (“a” in figure) is less
than limit, all pads must be replaced at the same time.
Front brake pad thickness “a” (lining thickness)
Standard: 10 mm (0.39 in.)
Limit: 2 mm (0.08 in.)

right and left.

Removal
1) Hoist vehicle and remove front wheel.
2) Remove caliper pin bolts (1).
3) Remove caliper (1) from caliper carrier (2).
NOTE
Hang removed caliper (1) with a wire hook (4)
or the like so as to prevent brake hose from
bending and twisting excessively or being
pulled.
Don’t operate brake pedal with brake pads
removed.

4) Remove brake pads (3).
5) Remove brake pad spring (1) as show in figure.
Installation
1) Apply small amount of pad grease “a” (included in
spare parts) to pad spring and set brake pad spring
as shown in figure.
2) Set brake pad springs (1), and install brake pads (2)
