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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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:
For the description (items) not found in this section refer to the same section of the Service Manual
mentioned in the FOREWORD of this manual.
When inspecting and servicing vehicle equipped with ABS, be sure to refer to section 5E2 first.
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.

5A-2 BRAKES PIPE/HOSE/MASTER CYLINDER
General Description
Master Cylinder Assembly
The master cylinder has two pistons and three piston cups. Its hydraulic pressure is produced in the primary (“a”
in the figure below) and secondary (“b”) chambers. The hydraulic pressure produced in the primary chamber
(“a”) acts on the rear wheel brakes.
Also, the hydraulic pressure produced in the secondary chamber (“b”) acts on the front wheel brakes.
WARNING:
Brake master cylinder cannot be disassembled. When anything faulty is found in it, it must be
replaced as an assembly.
CAUTION:
Brake master cylinder cannot be disassembled in principle. Should primary piston have come off
from cylinder while dismounting or handling it, wash it in the same specified fluid as that in reservoir
and place it back in cylinder.

On-Vehicle Service
Front Brake Hose/Pipe
REMOVAL
1) Raise and suitably support vehicle. Remove tire and wheel.
This operation is not necessary when removing pipes connecting master cylinder and flexible hose.
2) Clean dirt and foreign material from both hose end or pipe end fittings. Remove brake hose or pipe.
INSTALLATION
1) Reverse removal procedure for brake hose and pipe installation procedure.
For installation, make sure that steering wheel is in straightforward position and hose has no twist or kink.
Check to make sure that 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.
2) Perform brake test and check installed part for fluid leakage.
Tightening torque
Brake pipe flare nut (a) : 16 N·m (1.6 kg-m, 12.0 lb-ft)
Brake flexible hose bolt (brake caliper/2 joint) (b) : 23 N·m (2.3 kg-m, 17.0 lb-ft)
2-way joint mounting bolt (c) : 10 N·m (1.0 kg-m, 7.5 lb-ft)
Brake hose/pipe bracket bolt (c) : 10 N·m (1.0 kg-m, 7.5 lb-ft)
ABS actuator bracket bolt (c) : 10 N·m (1.0 kg-m, 7.5 lb-ft)
ABS actuator mounting bolt (d) : 9 N·m (0.9 kg-m, 6.5 lb-ft)
NOTE:
Insert E-ring till its end surface is flush with or lower than bracket end surface.
