PARKING AND REAR BRAKE
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.

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 necessary to re-
surface 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.
NOTE:
When drum is removed, visually inspect wheel cylinder for
brake fluid leakage. Correct leaky point, if any.
Brake Shoe
Where lining is worn out beyond service limit, replace shoe.
Thickness ªaº
Standard: 6.5 mm (0.24 in.)
Service limit: 3.0 mm (0.12 in.)
If one of brake linings is to service limit, all linings must be replaced
at the same time.
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.
INSTALLATION
NOTE:
See NOTE at the beginning of the section.
1) Before installing brake drum, check outer diameter of brake
shoes. If it is not within value as specified below, adjust it to spec-
ification by turning adjuster.
Outer diameter of brake shoes
ªaº: 219.4 ± 219.7 mm (8.638 ± 8.650 in.)
