Repair Instructions
Brake Pedal ComponentsS7RS0B4106019
CAUTION!
Never disassemble brake pedalassembly.
Disassemble will spoil its originalfunction. If
faulty condition is found, replaceit with new
one.

Brake Pedal Free Height InspectionS7RS0B4106001
1) Check brake pedal free height. If it is not within specification, check and ad just following item 2) and
6).
Brake pedal free height “a” from carpet
130 – 150 mm (5.1 – 5.9 in.) 2) Check measurement between booster mounting
surface and center of clevis pin hole. When booster
push rod clevis has been reinstalled, it is important
that the measurement is adj usted (refer to “Brake
Booster Inspection and Adjustment”).
3) Check stop light switch position . Adjust it if it is out of
specification.
4) Check pedal for dent.
5) Check brake booster for installation.
6) Check brake booster push rod for length.
Brake Pedal Play InspectionS7RS0B4106002
Pedal play should be within the following specification. If
out of specification, check stop light switch for proper
installation position and adjust if necessary.
Also check pedal shaft bolt and booster clevis pin
installation for looseness and replace if defective.

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”.

Master Cylinder Assembly Disassembly and
Assembly
S7RS0B4106013
Disassembly
1) Push in primary piston (1) to remove secondary
piston stopper pin (2) from master cylinder as
shown.
2) Remove circlip (1).
3) Remove piston guide and primary piston. Then remove secondary piston by blowing compressed air
(2) into hole. Be cautions during removal as
secondary piston jumps out.
WARNING!
Do not apply too highly compressed air
which will cause piston to jump out of
cylinder. Place a cloth to prevent piston from
damage. It should be taken out gradually with
moderately compressed air. Do not place
your fingers in front of piston when using
compressed air.

Assembly
CAUTION!
• Never use any mineral oil such as kerosene oil and gasoline when washing
and assembling parts.
• Check inside of cylinder wall, pistons and cup seals are free from any foreign objects
such as dust and dirt and use case not to
cause any damage with a tool during
assembly.
• Do not drop parts. Do not use any part which has been dropped.

1) Apply brake fluid to inside of cylinder and contact surface of piston assembly (new piston cups, new O-
ring and piston guide).
2) Install secondary return spring and secondary piston (1) into cylinder body (4).
NOTE
Align oblong hole in secondary piston (2)
with stopper pin hole (3) in master cylinder
body (4) when installing it.

3) Install primary piston assembly into cylinder body.
4) Install piston stopper pin (2) with pistons pushed in all the way and install it.

Booster Operation InspectionS7RS0B4106016
There are two ways to perform this inspection, with and
without a tester. Ordinarily, it is possible to roughly
determine its condition without using a tester.
NOTE
For this check, make su re that no air is in
hydraulic line.

Check Air Tightness
1) Start engine.
2) Stop engine after running for 1 to 2 minutes.
3) Depress brake pedal several times with the same load as in ordinary braking and observe pedal travel.
If pedal goes down deep the first time but its travel
decreases as it is depressed the second and more
times, air tightness is obtained.
4) If pedal travel doesn’t change, air tightness isn’t obtained.
NOTE
If defective, inspect vacuum lines and sealing
parts, and replace any faulty part. When this
has been done, repeat the entire test.

Check Operation
1) With engine stopped, depress brake pedal several times with the same load and make sure that pedal
travel doesn’t change.
2) Start engine while depressing brake pedal. If pedal travel increases a little, operation is satisfactory. But
no change in pedal travel indicates malfunction.
Check Air Tightness Under Load 1) With engine running, depress brake pedal. Then stop engine while holding brake pedal depressed.
