8. REAR WHEEL ALIGNMENT
Specialized equipment is required to measure the
rear wheel alignment. It is therefore recommended
that the vehicle be referred to a specialist suspension
workshop or an authorized dealer for measurement
and adjustment. The suspension components should
be inspected and renewed as necessary prior to having
the wheel alignment checked. If any suspension com-
ponents are renewed, the re ar wheel toe out may be
temporarily adjusted as described below.

TO INSPECT
Examine the tread of the tires. Excessive or
uneven wear will indicate misalignment or damaged
or worn components. Refer to the Tire Wear Trouble
Shooting Chart in the Wheels and Tires section for
possible causes and renew the faulty components.

Badly worn tires should be renewed prior to
having the wheel alignment checked.

TO CHECK AND ADJUST TOE OUT
NOTE: The following procedures are only a
temporary measure. Th e vehicle should be
referred to a specialis t suspension work-
shop or authorized dealer for accurate
measurement and adjustment.

(1) Position the vehicle on a level floor and
bounce the vehicle several tim es to settle the suspen-
sion. (2) Move the vehicle forward approximately 5
meters, with the front wheels straight ahead, to settle
the tires and suspension to the normal running
position.
(3) Place a chalk line across both tire treads at a
point equivalent to the stub axle height and to the rear
of the suspension. Place a vertical mark at the chalk line in the
centre of each tire.

(4) Using a telescopic gauge or tape measure,
measure the distance between both vertical marks and
record the measurement. (5) Move the vehicle forward until the marks are
to the front of the suspen sion, with the horizontal
marks at the same height as in operation (3). (6) Measure the distance between both vertical
marks. (7) The difference between the two measure-
ments will be the amount of toe out of the rear wheels. (8) If the toe out is not as specified, adjust the
rear control arm cams as follows: (9) Measure the distance between the inner
wheel rim and the adjusting flange on the rear
crossmember. Measure the distance on the other side
of the vehicle in the corresponding positions. (10) If the measurements are equal, loosen the
cam nut and turn the cam bolt to move the rear
control arm half the distance required to bring the
rear wheel toe out to specifications. Repeat this
operation on the other side of the vehicle.
(11) If the measurements obtained in operation
(9) are not equal, proceed as follows:
(a) If the toe out is less than specifications,
decrease the length of the shorter arm.
(b) If the toe out is greater than specifications,
increase the length of the longer arm.
NOTE: The toe out will alter approximately
2 mm with each graduation of the adjusting
cam.

body and tighten to the specified torque. (16) Using a blunt probe entered through the
sensing switch location hole, separate the pressure
differential pistons and install the switch actuating
lever between them. (17) Screw the sensing switch into its locating
hole until the detents on the switch body just contact
the locating hole facing (w ith the radial grooves).
Screw the switch assembly in a further half to one full
turn ensuring that the dete nts locate in the grooves.
(18) Install new valve seal s to the proportioning
valve plungers, with the serrations of the seals facing
away from the hexagons of the plungers.

to
retain the assembly. Ensure that the snap ring is
correctly seated in the groove. (23) Smear the new reservoir retainers with clean
brake fluid and install them into the reservoir ports.
Carefully press the brake fluid reservoir into position,
ensuring that the outlet extensions are fully inserted in
the reservoir retainers. (24) Install the reservoir cap insert to the dia-
phragm and press the cap assembly onto the reservoir.
TO INSTAL

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

(1) Pour a small amount of clean brake fluid into
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.

(6) Fill the master cylinder reservoir with clean

4. BRAKE SERVO UNIT

TO CHECK OPERATION
(1) With the engine switched off, apply the
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.

on chassis stands. Remove th e rear wheels and release
the handbrake.

(2) Working beneath the vehicle, remove the
exhaust pipe centre and rear heat shield retaining
bolts and maneuver the heat shields from the
vehicle.
(3) Remove the bolts and nuts retaining the
handbrake cable clamps to the underbody and discon-
nect the rear handbrake cable from the equalizer.
(4) On disc brake models, remove the handbrake
cable to bracket retaining clip on the rear of the
caliper and disconnect the handbrake cable from the
cam lever. Remove the cable from the vehicle.
(5) On drum brake models , proceed as follows:
(a) Remove and dismantle the rear brakes as

previously described.

Electrical System 197
Switch on all lamps and allow them to
illuminate for approximately five minutes to reduce
the charge of the battery and to apply a load to the
circuit.
Start the engine and gradually increase the
speed to approximately 2 500 rpm. The reading on
the ammeter should be approximately 75% of the
rated output of the altern ator. See Specifications.
Switch off all the lamps and run the engine at
1 500-2 000 rpm until the indicated charge is below
10 amps. The voltmeter should now read in excess of
13.6 volts.
NOTE: Should the alternator fail to reach
the specific output, the unit will have to be
removed and overhauled or a replacement
unit installed.

Should the voltage reading be above or
below Specifications, the regulator will have
to be renewed.

TO REMOVE AND INSTAL
Disconnect the negative battery terminal.
On 1.8 liter engines, remove the bolt secur-
ing the air cleaner intake duct and remove the air
cleaner intake duct. Drain the radiator by releasing the radiator
drain plug, located at the bottom of the radiator and
allow the coolant level to fall below the thermostat
housing level. NOTE: Refer to the Cooling and Heating
Systems section when refilling the radiator
coolant to its correct l
evel, failure to do so
could result in severe damage to engine
components.

Remove the retaining bolts securing the
thermostat housing, disconnect the hose from the
radiator and remove the thermostat housing and
radiator hose from the vehicle. Using a socket and extension bar, remove the
bolt securing the alternator to the drive belt tensioning
bar located under the alternator. On vehicles not equipped with air condition-
ing, remove the front splash guard from under the
front of the vehicle and remove the bolt securing the
alternator to the drive belt tensioning bar. Loosen the upper mounting bolts, slacken
the alternator drive belt and remove it from the
alternator pulley.
While supporting the alternator, remove the
upper mounting bolts and remove the alternator from
the vehicle. Installation is a reversal of the removal procedure
with attention to the following points:

Do not over tension the drive belt. Refer
to
the Engine Tune-up section for the correct belt
adjusting procedure. Ensure that the wiring and connectors are
securely located on the alternator.
