Brake Fluid InspectionS7RS0B0206035
1) Check around master cylinder and reservoir for fluid leakage. If found leaky, correct.
2) Check fluid level. If fluid level is lower than the minimum level of
reservoir, refilling is necessary. Fill reservoir with
specified brake fluid.
For the details, refer to “Brake Fluid Level Inspection
in Section 4A”.
CAUTION!
Since brake system of this vehicle is factory-
filled with brake fluid indicated on reservoir
tank cap, do not use or mix different type of
fluid when refilling; otherwise serious
damage will occur.
Do not use old or used brake fluid, or any
fluid from an unsealed container.

Brake fluid
Refer to reservoir cap of brake master cylinder.
Brake Fluid ReplacementS7RS0B0206017
Change brake fluid as follows.
Drain existing fluid from brake system completely, fill
system with specified fluid and carry out air purge
operation.
For air purging procedure, refer to“Air Bleeding of Brake
System in Section 4A”.
Brake Lever and Cable InspectionS7RS0B0206018
1) Inspect brake cable for damage and smooth movement.
Replace cable if it is in deteriorated condition. 2) Check tooth tip of each notch for damage or wear. If
any damage or wear is found, replace parking lever.
3) Check parking brake lever for proper operation and stroke, and adjust it if necessary.
For checking and adjusting procedures, refer to
“Parking Brake Inspection and Adjustment in Section
4D”.
Parking brake lever stroke
“a”: 4 – 9 notches (with 200 N (20 kg, 44 lbs) of pull
pressure)
Clutch Fluid InspectionS7RS0B0206019
1) Check clutch system for evidence of fluid leakage. Repair leaky point if any.
2) Check reservoir for fluid level referring to “Clutch
Fluid Level Inspection in Section 5C”.
If fluid is lower than minimum level of reservoir, refill
reservoir with specified brake fluid indicated on
reservoir cap.

If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol out
of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake
mechanisms, check for fluid on the linings.
If excessive fluid is found, replace the pads. If master cylinder piston seals
are satisfactory, check for
leakage or excessive heat co nditions. If leakage is not
found, drain fluid, flush with brake fluid, refill and bleed
system.
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.

Excessive Pedal Travel InspectionS7RS0B4106003
1) Start engine.
2) Depress brake pedal a few times.
3) With brake pedal depressed with approximately 300 N (30 kg, 66 lbs) load, measure brake pedal to wall
(dash panel silencer) clearance “a”. If clearance “a”
is less than specification, the most possible cause is
air in lines. Should clearance “a” remain less than
specification even after bleeding of system, other
possible infrequent cause is booster push rod length
out of adjustment.
• Bleed brake system. Refer to “Air Bleeding of Brake System”.
Brake arm pedal to wall clearance “a”
When pedal depressed at 300 N (30 kg, 66 lbs):
over 75 mm (2.95 in.)
Brake Fluid Level InspectionS7RS0B4106004
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 and MIN marks on reservoir.
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 lamp lights sometimes
during driving, replenis h fluid to MAX level.
When fluid decreases quickly, inspect brake
system for leakage. Correct leaky points and
then refill to specified level.

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.

Stop Light Switch AdjustmentS7RS0B4106005
Adjustment should be made as follows. Pull up brake
pedal toward you and while holding it there, adjust
switch position so that clea rance between end of thread
and brake pedal is as specified. Then lock it by turning
clockwise.
Clearance between brake pedal and stop light switch
“a”: 1.2 – 2.2 mm (0.05 – 0.08 in.)

Air Bleeding of Brake SystemS7RS0B4106006
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 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 rese rvoir with brake fluid and
keep at least one-half full of fluid during bleeding
operation.
Brake fluid
: Refer to reservoir cap (1) 2) Remove bleeder plug cap. Attach a vinyl tube (1) to
bleeder plug, and insert the other end into container
(2).
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 cy linder 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 referring to “Front Disc
Brake Components in Section 4B” and “Rear Disc
Brake Components in Section 4C”.

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 reserv oir up to specified level.
10) Check brake pedal for sponginess. If found spongy, repeat entire procedure of bleeding.
Front Brake Hose / Pipe Removal and
Installation
S7RS0B4106007
“Front Brake Hose / Pipe Construction”
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 mate rial 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 wh eel is in straight-forward
position and flexible hose has not twist or kink.
• 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.
