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.

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).

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.

SERVICING

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.

Cable Lock Nut Torque N·m (kg·cm/lb·in)

6 (60 / 52)

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.

GENERAL DESCRIPTION

Pulling up the parking brake lever by hand will set the parking brake. Once pulled up, the lever is held by

means of a ratchet type lock 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 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 to 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 or 7 notches.

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
