If
the thickness is

the
replacement

also the
con-
ditions
of the
fluid pipes
and replace them Im-
mediately in case of damage.
Checking the brake dilci

flg.36S and
368
The brake disc must be accurately
clean,
without
oil,
fat
or other
dirt and must not
show
any deep
scoring.
In
case
of replacement or overhauling
of the
brake disc,
it is
necessary to
check its
wobbling
.
This checking is carried out by means
of
a
proper gauge that must not read more than
0,2
mm.
Should the measurement be higher,
carefully
check the mounting
condition of the
disc
on
the
hub
and the
play of bearings
on
the hub
itself.
The loading torque
of
the screws
securing
disc
to hub
is 2,2 -:-
2,4 Kpm.
Checking the fluid level and changing the fluid

For
a good
working of
brakes,
these directions
are to be
followed:
1. Periodically
check
the flu id
level
which has to
be
at
the
transparent
part

of the
fluid reser-

Such level
must never fall
under this
transparent
part.

(or whenever
necessary) top up

loosening the

and
taking
off the rubber

The
minimum flu id level in the reservoir
for

warned by a warn-
ing
light

Completely
renew the brake fluid every 15000
km or
at
least
once a year.
4. The fluid pipes have to be always full and
without air
;
a
long
and
elastic
movement
of the
control

evidences the presence of air.
No alcohol
is
to be used for washing and no
compressed
air for drying up; use
trichloroethy-
lene for metallic parts.

Air bleeding (fig. 365 and 366)
Th
is operation
is required when the movement
of the control
lever is long and elastic because
of
the presence
of
air
inside
the braktng
circuits.
Proceedings are
as follows:

Turn
the

If
necessary,
top up
