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, REFER 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, or other
corrosion inhibitors) on threaded fasteners or
fasteners joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fasteners.
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/lever 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 duo–servo brake
(mechanical inside expansion type) built in the rear disc
brake. Parking brake adjustment is made through the
adjusting hole (bored through back plate). Parking brake
lever stroke should be adjusted to 6–8 notches. Refer to
Parking Brake Adjustment in this section.

SECTION

5D1–2 PARKING BRAKE SYSTEM (4x4 Model)

Operation

When pulled in the direction “A”, the parking lever presses
the secondary shoe against the brake drum using the
lever/shoe joint “B” as a fulcrum and pushes the strut in
the direction “C”. The strut ,in turn, presses the primary
shoe against the brake drum. Counter force “D” to the
primary shoe is transmitted again to the secondary shoe
through the fulcrum “B”. The secondary shoe contacts the
drum thereby producing braking effect. Clearance which
may result from worn parking brake shoe lining can be
adjusted by turning the adjusting screw. Refer to 

Parking

Brake Adjustment in this Section.
