.
The brake is
assembJ,
e d in the following
succession:
insert
the
c<~ms
in
the disk openings;
hook
return spring 9
in the
disk
opening;
fit
the
shoes with springs on the
ta1
ppet
spherical ends
and
on
the
caun bearing surfaces;
install
and
fix
the
driving
and
driven
levers
on
the
cam splines
maintaining
the
size
of 82:b5° as
illustrated in
Fig.
27.
The
parallelizm of
levers
.should
t
b
e
within
5°.
Upon fitting
the
brakes on the motorcycle
connect the
rod
with
the
driving
lever.
Turn
each
lever clockwise
ti.U
the shoes thrust
aga
inst
the wheel
brake
drum.
By
turning
the
rod
out/in the
fork
adjust the
distance
bet-
ween
the f.ork
holes
centers so that the pin connecting
the
fork with the
driven
lever freely enters
the holes
of the
lever
and
fork.
In this
case the rod
should
screw
in the fork for not
less
than
5
mm.
At the
end where there
is
no
lock
nut the
fork should be scre-
wed
onto
the
rod up
'to the end
of thread. Cotterpin the
rod
in
the
fork,
connect the
·rod with
if:he
driven
lever
and cotteroin
the
joint.

Wind up
the
return
spring.
If the above
assembling
requirements
are
observed and necessary conditions
for
the
reliable
operation of
the brake
at the
expence of simultaneous pressing of
both shoes
to
the
wheel br

be
provi

When
assemlbling the
brake
ca
re
should
be taken
to fit
the
shoes
in
their former
places, otherwise their wear-in
will
lbe
disturbed and
for some time the effici·ency of the
brake
will be poor.
It is
also
necessary to pay a ttention
to
the
ca
m surfaces
a.
g ainst
which
the
shoes
thrusted since the
cam surf
aces are asymmetrical
with respect to its
axis
of
ro tati<on.
Both shoes must
rest
on
the cam
planes equally offset
·relative
to
the pin.
The
brake should
be
adjusted in
the
course of run
as
required
by
turning
out the adjustin

is
obtained.
For
the
