TO REMOVE AND INSTAL
(1) Disconnect the negative battery terminal.
(2) Working in the engine compartment, mark
the relationship between the steering shaft universal
coupling joint and the steering gear pinion shaft. (3) Remove the pinch bolts from the universal
joint. (4) Working inside the vehi cle, remove the steer-
ing wheel as previously described. (5) Remove the steering column shroud screws,
unclip the lower and upper covers and remove them
from the steering column. (6) Disconnect all the steering column wiring
connectors. (7) Remove the lower trim from underneath the

vehicle.
Installation is a reversal of the removal procedure
with attention to the following points:

(1) Measure the dimension between the lower
bracket pin and the upper edge of the steering shaft as
shown in the illustration.

If the dimension is not as specified, the steering
shaft has collapsed and the steering column should be
renewed.

(2) Rotate the steering shaft in the column and
check the shaft bearing for roughness and damage.
Renew as necessary. (3) Inspect the steering shaft universal coupling
joints for wear and damage and renew as necessary. (4) Position the steering column assembly under

the dashboard ensuring that the floor bracket is
located correctly and that the steering shaft universal
joint is aligned with the steering gear pinion shaft
marks.

(5) Install all the steering bracket nuts and bolts
finger tight. (6) Install the universal coupling joint pinch bolts
and tighten securely.
(7) Tighten all the stee ring column nuts and
bolts securely. (8) Test the operation of all the steering column
controls when installation is complete.
TO DISMANTLE

(1) Remove the steering column assembly from
the vehicle as previously described. (2) Suitably mark the position of the universal
coupling joint and remove it from the steering shaft. (3) Mark the position of the rubber boot in
relation to the floor bracket and steering column.
Loosen the retaining bands and remove the boot and
floor bracket from th e steering column.
(4) Using snap ring pliers, remove the snap ring,
plain washer and wave washer from the upper end of
the steering shaft. (5) Loosen the combination switch retaining
screw, push the combination switch in, turn the switch
and remove it from the steering column. (6) Turn the ignition switch to the On position
and slide the steering shaft from the column assembly. (7) If necessary dismantle the tilt bracket com-
ponents after removing the through bolts. Note the
position of the components to aid assembly. (8) To remove and install the steering lock pro-
ceed as follows: (a) Remove the ignition switch retaining screw
and carefully withdraw the switch from the steering
lock bracket.

Brakes 175
A pressure proportioning valve is incorporated in
each circuit to prevent premature locking of the rear
wheels during severe braking.

The four wheel hydraulically operated brakes
utilize disc brakes on each front wheel and disc brakes
or leading and trailing drum brake shoes on each rear
wheel.

The front disc brakes comprise a disc attached to
the hub assembly and a caliper bolted to the steering
knuckle.

The rear disc brakes comprise a disc and hub
assembly attached to the rear stub axle and a caliper
and anchor plate bolted to the backing plate.

The front and rear calipers are of the sliding type.
As pad wear takes place, the caliper piston is allowed
to slide outwards through the seal to take up a new
position in the caliper bore. Elastic deformation of the
seal takes place when the brakes are applied, which
returns the piston slightly when the brakes are re-
leased. Thus a constant clearance is maintained
between the pads and the disc when the brakes are in
the off position.

The disc brakes do not require periodical adjust-
ment in service to compensate for pad wear as they
are self adjusting.

The leading and trailing shoe drum brakes on the
rear wheels use a double ended wheel cylinder to
operate both brake shoes at the top. The lower end of
each brake shoe abuts a fixed anchor point. The brake
shoes are automatically adju sted when the brakes are
operated.

The handbrake operates the rear brakes via a
cable arrangement.

3. MASTER CYLINDER
Special Equipment Required:
To Install New Seals — Suitable machined drift
TO REMOVE
(1) Depress the brake pedal several times to
deplete the vacuum from the system.

(2) Raise the bonnet and install covers to
both
the front mudguards. Cover the areas of paintwork
beneath the master cylinder with absorbent cloth.
(3) Disconnect the wiring from the pressure
sensing switch. (4) Disconnect the brake pipes from the master
cylinder and plug the outlets and pipes to prevent the
loss of fluid and the ingress of dirt.
(5) Remove the nuts retaining the master cylin-
der to the brake servo unit and remove the master
cylinder from the vehicle.
TO DISMANTLE

(1) Remove the master cylinder as previously
described. (2) Remove the reservoir cap and diaphragm,
drain and discard the brake fluid from the reservoir. (3) Carefully remove the reservoir from the
master cylinder by pulling it from the reservoir
retainers by hand. Remove and discard the retainers
from the master cylinder. (4) Using internal snap ring pliers, remove the
snap ring from the primary reservoir port. (5) Remove the fast fill valve assembly and the
O ring from the port. Remove and discard the valve
washer from the fast fill valve.

and remove it from the primary piston. Remove the
seal and guide. Discard the seal and retainer.
NOTE: The secondary piston must no! be
dismantled by removing the screw. This
assembly has a factory p reset length and the

the reservoir and pump the master cylinder pistons
with a blunt rod until fluid begins to emerge from the
outlets. (2) Install the master cylinder to the brake servo
unit and loosely install the master cylinder retaining
nuts. (3) Connect the brake pipes to the master cylin-
der outlets, but do not tighten at this stage. (4) Securely tighten the nuts retaining the master
cylinder to the brake servo unit.
(5) Securely tighten the brake pipes and connect
the wiring to the pressure sensing switch.

footbrake several times to exhaust all vacuum from
the system.
(2) Apply the footbrake and hold the brake pedal
fully depressed.
(3) Start the engine. If the servo unit is function-
ing satisfactorily a distinct downward movement of
the
brake pedal should be noticed. Should the pedal fail to move downward when the
engine has been started, the vacuum system can be
considered inoperative.

NOTE: If the pedal continues to fall away
there is a fault in the hydraulic system.

(4) Ensure that the brake pedal is fully released,
start the engine and run it at medium speed. Stop the
engine.

11. HYDRAULIC SYSTEM

TO BLEED
Bleeding the hydraulic system should only be
necessary when some portion of the hydraulic system
has been disconnected or fluid has been drained,
allowing air to enter the system.

The brake fluid in the hydraulic system should be
changed every 30 000 km or 18 months. The proce-
dure for changing the brake fluid and bleeding the
hydraulic system are simila r with attention to the
notes in the text.

There are four points in the system where bleeder
valves are installed, one on each front caliper and one
on each rear wheel cylinder or rear caliper.

14. Fill the fluid reservoir with clean hydraulic
brake fluid and maintain at least one third full
throughout the entire operation. 15. Attach a transparent hose to the bleeder
valve on the left rear cali per and immerse the other

end of the hose in a small amount of clean brake fluid
contained in a clean glass jar held higher than the
bleeder valve.

14. Unscrew the bleeder valve one
complete turn.
15. Have an assistant depress the brake
pedal slowly to the full extent of its travel. Close
the bleeder valve and allow the brake pedal to
r e t u r n w i t h o u t assistance. 16. Repeat operations (3) and (4) until
a con stant stream of fluid, without any air
bubbles, is being discharged into the gl ass jar,
