When
the
reservoir is
nearly empty it wil be
found
that
the
pedal
returns instantly
after depression,
due
to
the
presence
of air in
the
system.
On
the other hand,
if
the
pedal
takes
an abnormal
length
of time
to
return
to its raised
position,
this
may
indicate
that the felt
strainer
located at the bottom of
the
reservoir is
choked.
Under these
circum-
stances a new
felt
strainer must be fitted.
This
is
arranged
at
the
bottom
of the
resgrvoir,
and is
removed
by
disconnecting the two unions
(3),
and unscrewing
the
cap
(4).
An
aluminium
distance washer, the
felt
strainer
pad,
and
a
wire
ga:uze
support
can
then be taken out.
When
replacing the
parts,
the wire
gauze
support
should be refitted
in the cap
first, followed
by a new f.elt
pad
and, linally,
the
aluminium
distance washer
with
its
recessed
face
towards
the
felt fad,.
Packing
washers
are
provided
on either side of the aluminium
washer,
and it
should
be observed
that these
are in
position.
Normally,
the
felt
strainer
pad
should
be
discarded
and
a new
one
fitted
every
2o,ooo
miles, as directed on
page
34.

Plugs.
The
drip
plugs
are non-adjustable
and non-demountable,
and are
lettered
and numbered to
indicate
their
shapes and
relative
rates
of
oil
emission
respectively, a higher number indicating
a
greater
rate.
The
drip
plugs
never require cleaning, and,
being
non-demountable,
no attempt
must
be
made
to take them
apart.
If one is
suspected
of
being defective,
it
should be
replaced
with a new plug
of the same
rating.
