Broke
Shoes ond Broke Drums
When refitting
o broke shoe with o portiolly
worn lining moke sure thot it hos o thickness
sufficient to lost till the periodic
inspection
(ofter every 20,000 kilometres). The new lining
is 5 mm thick. When it is worn down to 1.5
to 'l
mm (4
to 3.5 mm when meosured
with the
shoe), the broke shoe hos to be reploced
with
o new.or
o reconditioned
shoe with glued-on
new lining. Be sure to reploce
the respective
broke shoes in both wheels to preserve
o uni-
form broking effect.
Speciol glues or cements
ond hordening ot
high temperotures
ore required when relining
the broke shoes so thot this
iob con
be done in
speciolized repoir shops
only. For informotion,
opply to the broke monufocturer -
Autobrzdy
Not. Corp., Joblonec
nod Nisou.
Broke drums are grey
cost-iron costings. Their
unequol weor
con be rectified
by mochining to
o 231 mm diometer.
No tool morks must be left
on their surfoce
which hos to be perfectly
smooth. The olignment deviotion
ond mochin-
ing toleronce should
not exceed 0.1 mm. The
moximum permissible weor is up Lo 232
mm in
diometer.
Only broke drums
with on identicol
diometer
ore permitted
to be mounted on one ond the
some oxle.
9.2 FRONT BRAKE
ASSEMBLY
Disnrontling ond Reossembly
1. Detoch
the broke fluid supply piping
from
the broke. Absolute cleonliness is o must.
Otherwise dirt ond foreign
motterwill penetrote
into the piping.
2. Renrove bolts lrolding
down the broke yoke
crnd lift owoy rlre broke
ossembly.
3. Use the MP 6-132 gouge
to set correctly
the broke (new
or repoired)
on reinstollotion.
4. Select the shims required
to fill the gop
between the end of the gouge
ond the foce of
the fostening lug.To position
correctly the
broke, insert shims
between the fostening lugs
cnd yokes. You con, however,
meosure direct
the distonce
between the fostening
lug ond the
trroke disk
ond set this distonce
in complionce
with Fig. 9.211 by odding pocking
pieces
to the
shim pock.
5. Using the respective
copscrews ond spring
'.^roshers, bolt down the yoke
to the lugs.
6. Attoch the supply hoses ond bleed
the
broke.
Replocing the Brake
Disk
A worn brol
grinding it to o thickness
of 7.5 mm. lf necess-
cry, reploce it with o new one 9 mm thick. The lowest
limit of thickness
of o still usoble
broke disk is 6.5 mm. The
moximum permissible
run-out of the friction surfoce is
0.15 mm.
1. After hoving lifted owoy
the broke os-
sembly, remove the wheel hub
ond then the
broke disk. 2. Reossemble the broke disk
with the wheel
hub using copscrews with spring
woshers.
3. Top
rrp or chonge the lubricont
in the
wheel
hub beorings ond reinstoll the broke ossembly
Replocing Broke Pods
The overoll thickness of o broke pod
with
new lining is 15 mm. When worn down to 7 mm
(with the lining 1.5 mm thick), the pod
is
unusoble.
Alwoys reploce
broke pods
on both ends of
the oxle of the some time so
thot their weor is
uniform. With regord to the coefficient of fric-
tion, they hove to be of the some
type ond
rnoke.
1. Suck off the hydroulic fluid from the tonk
so thot it is only holf filled.
2. Remove cotter pins
ond lift
owoy the broke
lining cover.
3. Remove the friction pod,
cleon thoroughly
the covities of the yokes, piston
ports,
ond dust
boots.
4. Fit the MP 6-134 force-off lever over the
broke disc ond drive the pistons
into the
cylinder bottoms by the presswe
of levers.
5. Ploce o new friction pod
into the broke
ossembly moking sure thot the clomp of the
thrust plote
fits into the collor of the piston
foce.

the opplicotion of the
brokes, ond led
through o rubber hose (tube)
to
the booster.
Removol ond Refitting
The broke booster is held down on the pedol
brocket by nuts ond spring
woshers. The lug of
the control volve press
button connects it with
the broke pedol,
on which it is secured by o re-
toining ring. These
mounting ports
or the con-
nections of the vocuum supply
ore to be hondl-
ed only when removing
or refitting the broke
booster.
However, we odvise you
to hove this
iob done
in o speciolized
repoir shop properly
instructed
by the broke
monufocturer. All rubber ports (in
the terms of current mointenonce,
this is
procticolly the seol of the press
button control-
ling the moster cylinder)
must be protected
from the effects of the broke fluid or other
lubriconts. Use petrol
for cleoning the rubben
ports.
Adiustment 1. Adiust the cleononce
between the broke
booster press
button ond the cylinder piston
whenever the moster
cylinder or the'broke
booster ore reploced,
or whenever there is ony
doubt concerning
the correctness
of the os-
sembly of the moster cylinder
with the broke
booster. Meosure the distonce between the
cylinder bottom recess
ond the cylinder flonge
nroting surfoce os well os the length of the
press button protruding
over the moting surfoce
of the booster.
Compore the meosurings
ond
odiust the length of the press
button by rototing
its threoded
end to obtoin o cleoronce of 0.5 to
1 mm between the press
button ond the piston.
Still better, you
can use special
tools Mp6.

Fit it on the
moster cylinder, push
its spindle into the cylinder till its rounded
end
rests ogoinst
the piston,
ond lock it in this po-
sitio-n with the respective
retoining screw.
Apply
the fixture to the booster
ond rotote the boostei press
button so thot it
iust touches the
lower
flot port
of the fixture spindle.
2. lf it is necessory
to level
the broke pedol
with the clutch pedol,
odiust the length
of the
contnol volve press
button lug.
Remove the broke
booster from the pedol
brocket, slip off the collor (cup),
connect the
booster with the pedol,
ond refit it tempororily
to the brocket.
Now rotote the hexogon on the
threods of the lug till both the clutch ond broke
pedol ore level. Remove once more the booster
from the pedol
ond pedol
brocket, neinstoll the
collor (cup),
ond complete the f inol reossembly.
9.7 BRAKE FLUID TANK, PIPING AND HOSES
Tonk ond Filling Hose
The broke fluid tonk is held in position
in its
brocket by o slip-over
clomp. Speciol rubber
hoses connect it with the broke ond clutch
moster cylinders.
Hose clips ore used to secure
the hoses on the tonk outlet sockets.
Both the
side ond centre outlet of the tonk ore con-
nected to the bnoke moster cylinder, the third
outlet being connected to the clutch moster
cylinder (see Fig. 12.111).
Pressure Piping ond Hoses
The rigid port
of the hydroulic line consists
of speciol steel pipes.
Their connections with
other ports of the line ore seoled off by clomp-
ing on the conicol surfoces-
lf these conicol surfoces
become domoged,
remove them ond form new ones by floring the
pipes. To do this, use the coulking holder,
type
MP 9-151. Clomp the pipe
in the holder so thot
it is level with its upper edge ond flore the pipe
with c coulking chisel. The holder is designed
to be clomped in o vice.
The holder
hos two drilled holes of 5 ond
6 mm in diometer so thot it con be used olso for
repoirs of pipes
of the clutch line. For dio.
5 mm holes, use the MP 9-152 ond for dio. 6 mm
holes, the MP 9-153 coulking chisel.
The flexiblepqrt
of the hydroulic line consists
of speciol hoses.
When fitting them to the reor
wheel cylinders, turn them in o position
which
will prevent
their contoct with ony ports
of the
cor in both extreme positions
of the cor sus-
pension. This is why the nipples ot the reor
wheels ore inclined
downword through on
ongle of 30 degrees from
the horizontol plone.

strictly the following instructions:
1. Mointoin the electrolyte level ot the level
of the perforoted
inserts between the plotes
or
so thot the inserts ore
covered with the electro-
lyte to o moximum height
of 4
mm. The
bottom
limit of the electrolyte level is 3 mm below the
perforoted inserts. Use only distilled woter for
topping up the electrolyte. Add electrolyte only
if it hos been obviously spilt from
the bottery.
In such cose, its density must correspond to
the density of the electrolyte Eemoining in the
bottery. 2. Keep the bottery terminols
cleon, remove
oxides occosionolly, ond
coot the terminols
with minerol
ielly.
3. Wipe off the electrolyte spilt
over the bot-
tery surfoce since it is conductlve ond couses
dischorging of the bottery.
4. Check the
chorging of the bottery occord-
ing to

voltoge drop using o voltmeter with o looding
resistor ond comporing the obtoined reoding
with on evaluotion toble or scole.
5. When chorging the bottery
outside the cor,
use chorging current volues occording to the
toble. The voltoge should be
controlloble in the
ronge from 12.6 to 16.8
volts. The fully dis-
chorged bottery is fully chorged in obout 13 to
20 hours when
o) the electrolyte ottoins o density of 1.28 in

of con-
tinued chorging;
c) oll cells ore lively gossing.
6. An olreody used bottery must not be left
without electrolyte or dischorged os it is opt to
suffer from
such o condition.
7. The bottery in on unused cor must
be
removed ond chorged outside the cor

Sofety Precoutions ond Other Meosures
During chorging, the electrolyte temperoture
must not exceed +40oC. As soon os this
tem'
peroture is reoched, interrupt the chorging or
lower the chorging current (this
opplies es-
peciolly to so-colled quick
chorging).
During chorging, on explosive mixture of hy-
drogen with oxygen is liberoted from the elec-
trrolyte. Therefore, the oreo where the bottery is
chorged must be ventiloted, ond it is forbidden
to opprooch with o noked flome (or
spork) the
cell filling holes (even
ofter o consideroble
period of time ofter the chorging hos been
completed). When chorging the bottery, open the filling
holes of its cells to enhonce degossing.
The electrolyte is on ocid hormful to the skin
ond clothes os well os to ports
of the cor fin-
ished in
enomel. Rinse with woter immediotely
ony contominoted spots.
13.3 ALTERNATOR The olternotor is o three-phose generotorwith
o built-in semiconductor rectifier
for feeding
electricol devices ond the bottery with
direct
current.
Alternotor lnstollotion ond Generol lnstructions

following principles
should be observed:
174
L
i g)
Excitotion of the olternotor by o current
supply outside the cor is not permitted.
Agoin the semiconductors would suffer.
h) A blown chorging worning lomp must be
reploced immediotely with o new
one. Other-
wise correct excitotion of the olternotor is
not ensured. Use o new lomp of
the some
roting (or input), i.
e., 1.5
to 2 W.
i) Be sure thot there is
o perfect
electricol
connection on the connecting terminols ond
thot the olternotor
ond regulotor
ore properly
eorthed.
i) The
olternotor is oeroted, open. Therefore
toke core when woshing the cor thot woter
or cleoning ogents do not get
into it through
the venting holes.
Removing the Alternqtor
1. Disconnect the bottery.
2. Disconnect the olternotor leods. lt will be
helpful to remember the colour of one conductor
ond its connection for reinstollotion.
3. Remove oll ports
holding the olternotor on
the engine, ond lift owoy the olternotor.
Reinstolling the Alternotor
1. Cleon oll mounting surfoces.
For the olter-
notor mounting, see Chopter 2.3, por.42.
2. With the bottery

Checking Voltoge Regulotor
on Cor
The regulotor operotion con be offected by
loosened connections ond on imperfect eorth- ing.
lf the wsrning lomp does not go
o.ut when
driving, i. e., if it glows
ot increosed engine
speed brightly or dimly,
or if it does not stort
glowing ofter stopping
the engine ond
o new
iurning of the ignition key in
the switch box,
the voitoge regulotor
is probobly
foulty. Another
symptom of o regulotor
foilure is
o poor
chorg-
irrg of tlre bottery or its
overchorging.. lf there
is nothing wrong with the regulotor, check the
reguloted voltoge over the regulotor which
slrould reod 13.2 volts ot the
minimum ond 14.8
volts ot the moximunr. This check
in the
cor
is only tentotive ond only
o check on
the test

Electricol Adiustment
The voltoge regulotot- should be tested
ond
odjusted only on o test bench
in o connection
slrown in Fig. 13.412.
At o lood of some
2

voltoge should correspond to
volues specified
in the column "Checking".
lf the checked volt-
oge is within the specified ronge, do
not odiust
the regulotor. Othenwise odiust it to the volues
specified in the column "Adiustment".
lf woter

Heodlomp Assembly
o) The fundomentol fostening
Port of
circulor
heodlomps is the
so-colled support plote
(rec-
tongulor plote)
ottoched to the bodywork by
copscrews with lock woshers. The
heodlomp
housing is bolted to this suPPort plote by bolts
with nuts ond lock woshers. One of the bolts holds
down olso the
lug of the eorthing coble-
The inner frome,
forming the
odiusting element
of the heodlomp insert, is ottoched
to the
hous'
ing by two speciol odiusting screws
ond two
tension springs. The heodlomp insert
is ot'
toched to
the bezel by
three copscrews.
There is one left-hond ond
one right-hond
support plote.
Both should
be mounted with the
oriow ond the word "TOP"
upwords. With
the
exception of the ouxiliory heodlomps, the
heod'
lomp inserts ore different for
the left-hond ond
the right-hond troffic. The leods
enter the hous-
ing through o
rubber grommet.
When r-eplocing the insert, remove
the bezel
copscrews. After
hoving fitted o new insert, it
is necessory to reodiust the
heodlomps.
