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.

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.

5C-2 PARKING AND REAR BRAKE
General Description
Drum Brake Assembly
The drum brake assembly has a self shoe clearance adjusting system so that drum-to-shoe clearance is main-
tained appropriate at all times. Rear brake is a drum type. It uses leading trailing operation when brake pedal is
depressed and when parking brake is applied on level road.
It also uses duo servo operation when parking brake is applied on gradient road and load is applied in longitudi-
nal direction of vehicle.
NOTE:
Replace all components included in repair kits to service this drum brake. Lubricate parts as speci-
fied.
WARNING:
If any hydraulic component is removed or brake line disconnected, bleed the brake system. The
torque values specified are for dry, unlubricated fasteners.

INSPECTION
Brake drum
Inspect drum for cleanliness. Check wear of its braking surface by
measuring its inside diameter.
Whenever brake drums are removed, they should be thoroughly
cleaned and inspected for cracks, scores, deep grooves.Brake dram inside diameter “a ”

5C-4 PARKING AND REAR BRAKE
Cracked, scored, or grooved drum
A cracked, drum is unsafe for further service and must be
replaced.
Do not attempt to weld a cracked drum.
Smooth up any slight scores. Heavy or extensive scoring will
cause excessive brake lining wear and it will probably be neces-
sary to resurface drum braking surface.
If brake linings are slightly worn and drum is grooved, drum
should be polished with fine emery cloth but should no be turned.
Brake shoe
Where lining is worn out beyond service limit, replace shoe.
If one of brake linings is to service limit, all linings must be
replaced at the same time.
Rear brake drum shoe thickness “a”
Standard : 7.1 mm (0.28 in.)
Service limit : 3.6 mm (0.14 in.)
INSTALLATION
For the details, refer to the same item of the same section in the
service manual mentioned in the FOREWORD of this manual not-
ing the following.
Before installing brake drum, check outer diameter of brake
shoes (3). If it is not within value as specified below, adjust it
to specification by turning adjuster (2).
Rear brake shoe outer diameter “a” :
253.3 – 253.7 mm (9.972 – 9.988 in.) NOTE:
When drum is removed, visually inspect wheel cylinder
for brake fluid leakage. Correct leaky point, if any.
CAUTION:
Never polish lining with sandpaper. If lining is polished
with sandpaper, hard particles of sandpaper will be
deposited in lining and may damage drum. When it is
required to correct lining, replace it with a new one.
NOTE:
See NOTE at the beginning of this section.
