Headlamp Alignment.
Double dipping headlamps are used on this model and these must be set correctly
in relation to the road and each other.
If adjustment is necessary proceed as follows
:-
Remove the front rim by slackening the securing screw.
If vertical adjustment
is required, set the light unit to the required position by means of the vertical ad-
justment screw, turn this in a clockwise direction to raise the beam and in an anti-
clockwise direction to lower it. If horizontal adjustment is required, set by means
of the two adjusting screws (one on each side of the light unit).
Screenwiper.
The screenwiper is of the heavy duty type and the motor is housed in the scuttle
above and aft of the heater unit.
To remove the motor it will be necessary to remove
casing above and aft of the heater which will expose a detachable plate upon which
the motor is mounted. When this panel has been removed and the rack and wiring
cables disconnected, the motor may be withdrawn.
BRAKES.
A
Girling Hydraulic Braking system is used on this model and employs two
trailing shoe brakes at the front and single leading shoe brakes at the rear, all being
operated by the foot pedal in conjunction with Vacuum Servo Motor.
A
handbrake
operates the mechanical linkage to the rear brakes. The supply tanks for the brake
and clutch master cylinders are integral with the cylinders and the fluid level should
be checked approximately every
2,000
miles and topped up if necessary, with Girling
Brake fluid, to within half an inch of the top of the tanks. This clearance is necessary
to allow for the expansion of the brake fluid.
Adjustment
(Rear Brakes).
No attempt should be made to adjust the brakes with the hand brake on.
Means
for adjustment are available at each rear brake backing plate, whereby each shoe
can be moved to the closest proximity of the drum without actual contact. On
the rear brakes there is one adjuster between each pair of shoes. This square ended
adjuster can be turned, a notch at a time, and the engagement, which can be heard
and felt, is caused by the flat sides of the adjuster engaging with the plungers sup-
porting the ends of the shoes. Turn the adjuster in clockwise direction as far as
it
will go. The brake shoes are then hard on and the adjuster should be turned back
one full notch to give the shoes the correct clearance from the drum. Press the
brake pedal hard once or twice to centralise the shoes in the drum.
Adjustment
(Front Brakes).
The front brakes do not require adjustment as these are of the Hydrostatic
self adjusting type.
Bleeding the Brakes.
If any of the hydraulic brake system has been disconnected,
it
will be necessary
to bleed the system, when the connections have been reassembled, to ensure that the
hydraulic fluid is free from air bubbles. There is a bleed nipple fitted on the back
of the brake backplate assembly for each expander. Connect the rubber drain tube
to one of the brake bleed nipples and immerse the open end of the tube into a jar,
partly filled with brake fluid. Then
fit
a spanner on the Hexagon sides of the bleed
nipple and unscrew the nipple one full turn. The brake pedal should now be applied
repeatedly with slow full strokes until the fluid entering the jar from the drain tube
is completely free from air bubbles. The bleed nipple should now be tightened
with the spanner during a down stroke of the brake pedal. Repeat for the other
nipples.
