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.

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

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.

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
