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:
When inspecting and servicing vehicle equipped with ABS, be sure to refer to section 5E or 5E1 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 as-
sure proper retention of all parts. There is to be no welding as it may result in extensive damage and
weakening of the metal.

CHECK AND ADJUSTMENT
BLEEDING BRAKES
CAUTION:
Brake fluid is extremely damaging to paint. If fluid should
accidentally touch painted surface, immediately wipe
fluid from paint and clean painted surface.
NOTE:
For vehicle equipped with ABS, make sure that ignition switch
turns off.
Be sure to bleed air of brake system according to following proce-
dure when its oil hydraulic circuit has been disconnected.
Hydraulic lines of brake system consists of two separate lines, one
for front wheel brakes and the other for rear wheel brakes.
Air bleeding is necessary at right and left front wheel brakes, left
rear wheel brake and LSPV (if equipped without ABS), i.e. 4 places
(3 places for vehicle with ABS) in all.
1) Fill master cylinder reservoir with brake fluid and keep at least
one-half full of fluid during bleeding operation.
2) Remove bleeder plug cap.
Attach a vinyl tube to bleeder plug of wheel cylinder, and insert
the other end into container.
3) Depress brake pedal several times, and then while holding it de-
pressed, loosen bleeder plug about one-third to one half turn.
