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.

HOLDEN will call out those fasteners that require a

replacement after removal. HOLDEN 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.

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.

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: 1.0m (0.039in)

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

loos ening the adjust nu t of the hand brake lever.

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

the shoe adjusting screw downward with a small

screwdriver so th at 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 s ure that the re 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 s ure there is no brak e dragging. Then tig hten

the cable lock nut

Torque : 13 N·m (113 lbin)

7. When poor braking effect possibly resulting from

insufficie nt br eak–i n is felt , or just after rep lace ment

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.

• If braking effect still remains poor after the above

break– in, wait fo r som e time unt il parking br ake shoe

cools down and repeat the procedures 8. and 9.

noted 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.
