Front Disc Brake Pad On-Vehicle InspectionS6RW0D4206002
Inspect pad linings (1) periodically according to
maintenance schedule whenever wheels are removed
(for tire rotation or other reason). Take a look through
each end and inspection hole of caliper and check lining
thickness of outside and inside pads.
If lining is worn and its thickness (“a” in figure) is less
than limit, all pads must be replaced at the same time.
Front brake pad thickness “a” (lining thickness)
Standard: 10 mm (0.39 in.)
Limit: 2 mm (0.08 in.)

Front Disc Brake Caliper Disassembly and
Assembly
S6RW0D4206006
Disassembly
CAUTION!
Clean around caliper with brake fluid before
disassembly.

1) Remove disc brake piston with air blown into flexible
hose joint bolt installation hole.
WARNING!
Do not apply too highly compressed air
which will cause piston to jump out of
cylinder. Place a cloth (1) 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.

2) Remove cylinder boot.
3) Remove piston seal using a thin blade like a
thickness gauge, etc.
CAUTION!

twisted.
• After reassembling brake lines, bleed air
from them.

Before installing caliper to carrier, install slide pins with
rubber grease included in slide pin / boot set applied into
caliper carrier hole and check for its smooth movement
in thrust direction.
• Install piston seal, boot and piston to caliper referring
to the following instructions.
1) Replace with a new piston seal (1) at every overhaul.
After applying rubber grease included in piston seal
set or brake fluid, fit piston seal (1) into groove in
cylinder taking care not to twist it.2) Before inserting piston (1) into cylinder, apply rubber
grease included in piston seal set or brake fluid to
new boot (a) and install it onto piston as shown.
3) Fit boot as it is in figure into boot groove in cylinder
with fingers.
4) Insert piston into cylinder by hand and fit boot in boot
groove in piston.
NOTE
Check that boot is fitted in boot groove
securely all around piston and cylinder.

General Description
ABS DescriptionS6RW0D4501001
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.
Rear wheel speed sensor of 4WD vehicle is
integrated in rear wheel hub assembly and supplied
as rear wheel hub assembly part.
Front wheel speed sensor and rear wheel speed
sensor of 2WD model are separated from wheel hub
assembly and supplied as spare parts.
• ABS warning light which lights to inform abnormality
when system fails to operate properly.• ABS hydraulic unit / control module assembly is
incorporated ABS control 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 supply 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.
• G sensor which detects body deceleration speed for
4WD model.
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 proportioning valve, by the signal from
wheel sensor independently of change of load due to
load capacity and so on. And if the EBD system fails to
operate properly, the brake warning light lights to inform
abnormality.
