Brakes
Hand brake The hand brake is automatically adju sted with the rear brakes. If there is excessive
movement of the
hand brake lever, consult your Distributor or Dealer.
Lubrication Charge the nipples on the hand brake balance lever (2) and han d brake cable (1)
Fig. 5 with one of the recommended greases.
Preventive In addition to the recommended periodical inspection of brake components it
maintenance is advisable as the car ages, and as a precaution against the effects of wear and
deterioration, to make a more searching inspection and renew parts as necessary.
It is recommended that:
(1) Disc brake pads, drum brake linings, hoses, and pipes should be examined
at intervals no greater than those laid down in the Pass port to -Service.
(2) Brake fluid should be changed completely every 18 mo
nth s or 18,000 miles
whichever is the sooner.
(3) All fluid seals in the hy
dra ulic system should be renewed , and all flexible
hoses should be examined
and renewed if necessary every 3 years or .
36,000 miles (60000 km.) whichever is the sooner. At
the same time the
working surface of the piston and of the bores of the master cylinder,
wheel cylinders, and
other slave cylinders should be examined and new
parts fitted where necessary .
Care mu st be taken always to observe the following points:
(a) At all times use the rec ommen ded brake fluid.
(b) Never leave fluid in unsealed containers. It absorbs moisture quickly and
this can be dangerou s if used in the braking system.
(c) Fluid drained from the system or used for bleeding is best discarded.
(d) The necessity for absolute cleanliness th roughout cannot be over-
em
pha sized.

Alternato r The follo wing precautions must be observed to prevent inadvertent damage to
the alternator
and its control equipment.
Polarity. En sure
that the correct battery polarity (negative ground) is maintained
at all times; reversed battery or charger connections will damage the alt

att ery connections. The battery must never be disconnected while the engine is
running.
Battery The battery must be kept clean and dry, and the terminals should be smeared
Fig. 1 with petroleum jelly. The vehicle must be level when the electrolyte in the cells -
is being checked.
More frequent topping-up of the electrolyte levels may be necessary in hot
weather or when long journ eys are made .

OTE.-Do not leave the battery in a discharged state for any length of time .
When not in regular use have the battery fully charged,
and every fortnight give
a short refresher charge to prevent permanent damage to the
batt ery plates.
'P acemaker ' (Type A9, AZ9, All, AZll). The electrolyte levels (1) are visible
throug h the
tran sluscent battery case or may be checked by fully raising the
vent cover (2)
and tilting it to one side. The electrolyte level in each cell must
be maintained so that the separator plates (3) are just covered. To avoid flooding,
the battery must not be topped up within
half an hou r of it having been char ged
from any source other than the generating system fitted to the car.
To
top up the levels raise the vent cover and pour distilled water into the trough
(4) until all the rectangular filling slots (5) are full and the bottom of the trough
is just covered . Press the cover firmly into position; the c orr ect quan tity of distilled
water will automatically be distributed to each cell. In extremely cold conditions,
run the engine immed iately after topping-up to mix the electrolyte.
