SERVICE PRECAUTION
WARNING:
IF SO EQUIPPED WITH 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 specification. Following these instructions can help you avoid damage to
parts and systems.

DIAMETER CHECK
Check the rear drum inside diameter by measuring at
more than two portions as shown in the figure.
If the inside diameter is greater than the limit, replace
the rear rotor.

PARKING BRAKE LINING INSPECTION
Check the shoe assemblies for wear by removing the
brake drum rotor.
Replace the shoe assemblies, if the lining thickness is
less than 1.0 mm (0.039 in).
Minimum Limit mm (in)

PARKING BRAKE ADJUSTMENT
1. Adjustment of Parking Brake Assembly
·Prior to lever stroke adjustment, adjust the rear
brake shoe/rotor (drum) gap. Perform this
procedure by loosening the adjust nut of the
equalizer.
a) 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.)
b) 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.

2. Adjustment of Parking Brake Cable
a) Turn the equalizer nut so that the parking
brake lever travels 6 or 7 notches when pulled
up with a force of 30 kg (66 lb).
b) Make sure there is no brake dragging and
tighten the cable lock nut.

3. Break-in of Parking Brake Shoe
·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 by driving vehicle as follows:
a) Forward 50 km/h (30 mph) x 400 m (About 30
seconds) with a lever pull force of 15 kg (33 lb),
and
b) Backward 10 km/h (6 mph) x 50 m (18 seconds)
with a lever pull force of 15kg (33 lb).
NOTE:
Break-in procedure must be performed under the
safety conditions and traffic rules.
·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 a) and b) notes above.
·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.
·Excessive break-in may cause premature wear
of the parking brake lining.
