Air Bag Warning
Refer to “Air Bag System Service Warning in Section 00”.
Brakes Diagnosis Note
Refer to “Brakes Diagnosis Note”.
General Description
Brakes ConstructionS7RS0B4101001
When the foot brake pedal is depressed, hydraulic pressure is developed in the master cylinder to actuate pistons (two
in front and two in rear).
The master cylinder is a tandem master cylinder. Brake pipes are connected to the master cylinder and they make two
independent circuits. One connects front right & rear left brakes and the other connects front left & rear right brakes.
In this brake system, the disc brake type is used for the front wheel brake and the rear wheel brake.
The parking brake system is mechanical. It applies brake force to only rear wheels by means of the cable and
mechanical linkage system. The same brake shoes or pads are used for both parking and foot brakes.

“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.

Brake Hose and Pipe InspectionS7RS0B4106009
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.

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.

5) Apply small amount of rubber grease (included in spare parts) to mating surface of “a” (piston cup (3)
and piston guide (1)) and “b” piston guide (1) and O-
ring (2)).
6) Apply small amount of s ilicon grease (included in
spare parts) to mating surfaces of “c” (rod seal (4)
and primary piston (5)).
7) Install piston guide (1) and circlip (6).Master Cylinder Assembly InspectionS7RS0B4106014
Inspect all disassembled parts for wear or damage, and
replace parts if necessary.
NOTE
• Wash disassembled parts with brake fluid.
• Do not reuse inner parts and rubber parts.

Inspect master cylinder bore for scoring or corrosion. It is
best to replace corroded cylinder. Corrosion can be
identified as pits or excessive roughness.
NOTE
Polishing bore of master cylinder with cast
aluminium body with anything abrasive is
prohibited, as damage to cylinder bore may
occur.

Rinse cylinder in clean brake fluid. Shake excess rinsing
fluid from cylinder. Do not use a cloth to dry cylinder, as
lint from cloth cannot be kept from cylinder bore
surfaces.
Brake Booster ComponentsS7RS0B4106015
CAUTION!
Never disassemble brake booster. Disassembly will spoi l its original function. If faulty condition is
found, replace it with new one.

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.
