Service Precaution
WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE
SRS COMPONENTS OR THE SRS WIRING, REFE
R
TO THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY, OR OTHERWISE UNNEEDED SRS SYSTEM
REPAIRS.

CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, o
r
other corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener.
When you install fasteners, use the correct
tightening sequence and specifications. Following
these instructions can help you avoid damage to
parts and systems.

General Description
Pulling up the parking brake lever by hand will set the
parking brake. By means of a ratchet type lock, the
lever can be held in that position until it is released. The
position of the lever is transmitted through cable/leve
r
systems to the rear wheels. These parts are designed
to obtain sufficient braking force even when parking on
slopes. When the parking brake is set, or when the
ignition SW is in the "ON" position, the brake warning
light illuminates. The rear wheel parking brake is a
leading-trailing brake (mechanical inside expansion
type) built in the rear drum brake. Parking brake
adjustment is made through the adjusting hole (bored
through back plate). Parking brake lever stroke should
be adjusted to 8

14 notches with 30kg (bench seat) o
r
6

8 notches with 30kg (bucket seat). Refer to “Parking
Brake Adjustment" in this section.
