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.

Inspection
Hold center of parking brake lever grip and pull it up with
200 N (20 kg, 44 lbs) force.
With parking brake lever pulled up as shown, count
ratchet notches. There should be 4 to 9 notches.
Also, check if both right and left rear wheels are locked
firmly.
To count number of notches easily, listen to click sounds
that ratchet makes while pulling parking brake lever
without pressing its button.
One click sound corresponds to one notch.
If number of notches is out of specification, adjust cable
referring to adjustment procedure so as to obtain
specified parking brake stroke.
NOTE

160 N (16.0 kg, 35.3 lbs) load.
• Parking brake lever (1) has been pulled up a few times with about 200 N (20 kg, 44 lbs)
load.
If parking brake cable is replaced with new
one, pull up parking brake lever a few
times with about 500 N ⋅m (50 kg, 110 lbs)
force.

1) Release parking brake lever (1).
2) Loosen parking brake lever adjust nut (2) fully.

General Description
ABS DescriptionS7RS0B4501001
The ABS (Antilock Brake System) controls the fluid
pressure applied to the wheel cylinder of each brake
from the master cylinder so that each wheel is not locked
even when hard braking is applied.
This ABS has also the following function.
While braking is applied, but before ABS control
becomes effective, braking force is distributed between
the front and rear so as to prevent the rear wheels from
being locked too early for better stability of the vehicle.
The main component parts of this ABS include the
following parts in addition to those of the conventional
brake system.
• Wheel speed sensor which senses revolution speed of each wheel and outputs its signal.
• ABS warning light which light s to inform abnormality
when system fails to operate properly.
• ABS hydraulic unit / cont rol module assembly is
incorporated ABS co ntrol module, ABS hydraulic unit
(actuator assembly), solenoid valve power supply
driver (transistor), solenoid valve driver (transistor),
pump motor driver (transistor).
– ABS control module which sends operation signal to ABS hydraulic unit to control fluid pressure
applied to each wheel cylinder based on signal
from each wheel speed sensor so as to prevent
wheel from locking.
– ABS hydraulic unit which operates according to signal from ABS control module to control fluid
pressure applied to wheel cylinder of each 4
wheels.
– Solenoid valve power supp ly driver (transistor)
which supplies power to solenoid valve in ABS
hydraulic unit.
– Solenoid valve driver (transistor) which controls each solenoid valves in ABS hydraulic unit.
– Pump motor driver (transistor) which supplies power to pump motor in ABS hydraulic unit.
This ABS is equipped with Electronic Brake force
Distribution (EBD) system that controls a fluid pressure
of rear wheels to best condition, which is the same
function as that of proportion ing valve, by the signal from
wheel sensor independently of change of load due to
load capacity and so on. An d if the EBD system fails to
operate properly, the brake warning light lights to inform
abnormality.
ABS Hydraulic Unit / Control Module Assembly
Description
S7RS0B4501002
ABS control module is a component of ABS hydraulic
unit / control module asse mbly and has the following
functions.
Self-Diagnosis Function
ABS control module diagnose s conditions of the system
component parts (whether or not there is any
abnormality) all the time and indicates the results
(warning of abnormality occurrence and DTC) through
the ABS warning light as described.
• When ignition switch is turned ON, ABS warning light lights for 2 seconds to check its circuit.
• When no abnormality has been detected (the system is in good condition), ABS warning light turns OFF
after 2 seconds.
• When an abnormality in th e system is detected, ABS
warning light lights and the area where that
abnormality lies is stored in the memory of EEPROM
in ABS control module.
