HANDBRAKE ADJUSTMENT
Adjustment of the brakes shoes already
described automatically readjusts the hand-
brake mechanism.
The cables are correctly set during assembly
and only maladjustment will result from
altering the mechanism.
From the compensating linkage to the brake
levers mounted on the wheel cylinders are
transverse cables which are of a set length
when leavine the works. Thev are however
adjustable
2
their inner ends and should
these have been tampered with it is necess-
ary to check the following:
he
cable assembled to the right-hand
cylinder lever is 12.97" f .06" between
centres.
The left-hand is 26.85" f .06", this gives
the correct angle of the compensator lever
as 17". Only when a complete overhaul
is necessary should the handbrake cables
require resetting.
T o carry out this operation, the brake
shoes should be locked up in the brake
drums with the handbrake in the
" off"
osition. Any slackness that is in the cable
Lom compensator to handbrake lever should
be removed at the handbrake lever end.
8. TO BLEED HYDRAULIC SYSTEM
Except for periodic inspection of the reser-
voir in the master cylinder, no attention
should be required. If, however, a joint
is uncoupled at any time, or air has entered
the system the system must be bled in
order to expel the air which has been
admitted. Air is compressible and its
presence in the system will affect the
working of the brakes.
