Inspection and Repair

Parking Brake Lining Inspection

Check the shoe assemblies for wear by removing the
brake drum.
Replace the shoe assemblies if the lining thickness is less
than 1.0 mm (0.039 in).

Minimum limit: 1.0 m (0.039 in)

Parking Brake Rotor (Drum) Inspection

Refer to“Rear Disc Brakes” in Power-Assisted Brake
System section for inspection procedure of the rotor
(drum).

Parking Brake Adjustment

1. Prior to lever stroke adjustment, adjust rear brake

shoe/rotor (drum) gap. Perform this procedure with
loosening the adjust nut of the hand brake lever.

2. Remove the adjusting hole plug (rubber) and turn the

shoe adjusting screw downward with a small
screwdriver so that shoes will expand until they get
into close touch with the rotor. (Turn down the
adjusting screw notch by notch until the rotor does not
turn.)

3. Turn the adjusting screw in the opposite direction

(upward) until the rotor can be turned lightly. Standard
number of notches to turn upward: 7 or 8
Turn the rotor and make sure that there is no brake
dragging.

4. After the rear brake shoe/rotor (drum) gap has been

adjusted, perform parking brake cable adjustment.

5. Turn the adjusting nut so that the parking brake lever

travels 6–8 notches when pulled up with a force of 30
kg (66 lb).

6. Make sure there is no brake dragging. Then tighten

the cable lock nut

Torque : 13 N·m (113 lb in)

7. When poor braking effect possibly resulting from

insufficient break–in is felt, or just after replacement
of parking brake shoe, be sure to conduct break–in as
follows:

8. Forward 50 km/h (30 mph) 

×

 400 m (About 30

seconds) with a lever pull force of 15 kg (33 lb).

9. Backward 10 km/h (6 mph) 

×

 50 m (About 18

seconds) with a lever pull force of 15 kg (33 lb).

NOTE: Break–in procedures must be performed under
safe conditions and traffic rules.

f

If braking effect still remains poor after the above
break–in, wait for some time until parking brake shoe
cools down and repeat the procedures 8. and 9. noted
above.

f

On completion of break–in, inspect parking brake
lever stroke, and if the lever does not come within the
specified number of notches when pulled up,
readjust.

f

Excessive break–in may cause premature wear of
the parking brake lining.

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
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/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 leading/trailing brake
(mechanical inside expansion type). Parking brake
adjustment is made through the adjusting hole (bored
through back plate). Parking brake lever stroke should be
adjusted to 6 notches. Refer to “Parking Brake
Adjustment” in this section.
