Before installing caliper (cylinder body) to carrier, check to ensure
that guide pin (pin bolt) inserted in each caliper carrier hole can be
moved smoothly in thrust direction.
NOTE:
Where temperature gets as low as ±30C in cold weather, use
rubber grease whose viscosity varies very little even at ±40C
(±40F).
INSTALLATION
1) Install caliper to caliper carrier.
2) Torque caliper pin bolts to specifications.

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System
Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
All brake fasteners are important attaching parts in that they could affect the performance of vital parts
and systems, and / or could result in major repair expense. They must be replaced with one of same part
number or with an equivalent part if replacement becomes necessary. Do not use a replacement part of
lesser quality or substitute design. Torque values must be used as specified during reassembly to assure
proper retention of all parts. There is to be no welding as it may result in extensive damage and weakening
of the metal.

5E1-2 ANTILOCK BRAKE SYSTEM (ABS) (OPTIONAL)
GENERAL DESCRIPTION
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 is a 4-wheel type
which controls the fluid pressure applied to the wheel cylinder of each of the four brakes to prevent each wheel
from getting locked.
The component parts of this ABS includes 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.
In this ABS, ABS hydraulic unit (actuator assembly), ABS control module, pump motor relay and fail-safe relay
are combined as one component.
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 of 4 wheels.
Fail-safe (solenoid valve) relay which supplies power to solenoid valve in ABS hydraulic unit and pump motor
relay.
Pump motor relay which supplies power to pump motor in ABS hydraulic unit.
ªABSº warning lamp which lights to inform abnormality when system fails to operate properly.
G sensor which detects body deceleration speed. (For 4WD model only)
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 lamp lights to inform abnormality.
