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.

Use spring woshers under
the
heods of copscrews.
Before instolling the pipes, prepore
ouxiliory
yokes (or use lengths of wires ottoched to the
provisionolly screwed-in copscrews of the pipe-
line guord) to liold the pipes
in the moulded
chonnel in
the floor before
the finol fostening
of their guord.
The woter line runs
