1. DESCRIPTION
The steering gear is a rack and p i n i o n type
which is mounted on the lower section of the engine
compartment bulkhead by rubber mountings and
brackets.

The design of this assembly requires a range of
special tools to dismantle and assemble the steering
gear. If the steering gear is found to have a fault which
requires overhaul of the rack and pinion, it is recom-
mended that this be performed by an authorized work-
shop or steering specialist.

However, the procedures for the removal and
installation of the steering gear and the renewal of the
tie rods, the tie rod ends and the rubber boots are fully
covered in this section.

The rack and pinion assembly requires no lubri-
cation during service.

The steering column is of the energy absorbing
type designed to compress in the event of a severe
front end collision. The energy absorbing units are the
outer steering column, the tilt bracket and the steering
shaft. All these units shoul d be handled with extreme
care if service operations are performed on the
steering column assembly.

(3) Remove the steering wh eel retaining nut and
mark the steering shaft and steering wheel hub in
relation to each other as an aid to assembly.
(4) Remove the steering wheel from the steering
shaft.
NOTE: If the steering wheel will not sepa-
rate from the steering shaft, loosen the horn
pad retaining screws at the rear of the
steering wheel and withdraw the horn pad
after disconnecting the wire. A puller can
now be used to pull the steering wheel from
the steering shaft. Do not strike the end of
the steering shaft as sharp blows can cause
irreparable damage to the collapsible steer-
ing shaft.

(5) If necessary the steering wheel can be dis-
mantled as shown in the illustration.

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

(1) Apply a light coat of multipurpose grease to
the horn slip ring and the turn signal canceling pins.
(2) Ensure that the marks on the steering wheel
and steering shaf t are aligned.
(3) Tighten the steering wheel retaining nut to
the specified torque.

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.
(6) Remove the proportioning valve plugs and
the O rings. Discard the O rings. Withdraw the springs
and valve plungers from the master cylinder. Remove
and discard the seals from the valve plungers. (7) Remove the pressure sensing switch and
lever assembly from the master cylinder. {8) Remove the cylinder end plug from the
master cylinder. Remove and discard the O ring from
the plug.

(9) Carefully tap the front of the master cylinder
vertically on a block of wo od and remove the pressure
differential pistons from the master cylinder. Remove
and discard the O rings from the pistons. (10) Push the primary piston forward in the
cylinder with a blunt rod and while holding the
pressure, remove the stop pin from the master cylin-
der.
(11) The primary piston may now be withdrawn
from the cylinder bore. The secondary piston, retainer
and spring can also be withdrawn by carefully tapping
the master cylinder on a block of wood. (12) Prise the legs of the seal retainer upwards
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
screw must not be altered in service.

(13) Remove the main seal and the guide from
the front of the secondary piston. Stretch the rear seal
from the groove and remove it from the piston. Take

duct removed for clarity. 1.8 liter model.

BODY
1. WINDSCREEN AND REAR GLASS
The renewal or replacement of the windscreen
and the rear glass follows the same basic procedure.

The successful installation and sealing of the
windscreen or rear glass will depend to a large extent
on the technical knowledge and experience of the
operator and it is not recomm ended that rear glass or
windscreen replacement be attempted by anyone
lacking in previous experience.

2. FRONT DOORS
INTERIOR HANDLES AND TRIM PANEL

TO Remove and Install
On models with manual windows, carefully
prise out the armrest trim plugs and remove the
retaining screws. Withdraw the armrest from the
vehicle. On models with power windows, proceed as
follows: Carefully prise out the armrest trim plugs
and remove the retaining screws. Hold the armrest away from the door trim

Lift the switch assembly and disconnect the
wiring connector. Remove the hidden screw working through
the switch aperture. Withdraw the armrest from the
vehicle.
Remove the screw retaining the remote con-
trol assembly escutcheon to the door and remove the
escutcheon.
On models with manual windows, lever back
the regulator handle escutcheon and using a suitable
wire hook withdraw the handle retaining clip and
remove the handle and escutcheon. Alternatively, a piece of sturdy cloth can be used
to remove the regulator handle by sliding the cloth
behind the handle and pulling on each end of the cloth
in a see-saw action to release the retaining clip.
