I. BLEEDING THE BRAKES ON SALOON AND ESTATE VEHICLES ( 9/1976- )
A. FRONT BRAKE BLEEDING
NOTE : To avoid emulsifying the fluid
and the
consequent formation of air-pocket in the system,
the circuit should not be under pressure when this
operation is carried out.
1. Release pressure in circuits :
a) Raise front of vehicle (wheels free 1.
b) Slacken pressure regulator bleed screw ( 1 ).
Remove front wheels.
c ) Place CI transparent tube over each bleed
screw (2 ) with its oiher end in CI clean
container.
d) Hold r/on,,,
brake pdnl ar,d loose,, blvcrl
*cr(Iws (2). 2. Bleeding :
(I 1 Start engin’e (idling speed 1 and maintain brake
pedal fully depressed.
b) Tighten pressure regulator bleed screw and
allow fluid to flow until bleed tubes ore
free of air bubbles.
Then tighten bleed screws (2 ).
c) Release broke pedal and remove bleed tubes.
Check the bleed screws for .leaks by depres-
sing brake pedal to fullest extent.
Stop engine.
Fit rubber protectors over the bleed screws.
d 1 Replace front wheels and lower vehicle to
the ground.
B. REAR BRAKE BLEEDING
3. Release pressure in circuits
a) Set monuol height control to lou posi/iou.
b 1 Slacken pressure regulator bleed screw ( 1 )
c) Wait until vehicle has reoched.its lowest
point.
Raise rear of vehicles (wheels free )
Remove lower rear wheel panels and rear
wheels.
d 1 Set manual height control to
hifih positior,
e ) Place Q transparent tube over each bleed
screw with its other end in (I cl&n container.
f ) Open bleed screws (3 ) and depress broke
pedal to fullest extent. 4. Bleeding :
(I) Tighten regulator bleed screw ( 1 1.
Slur/ w?@nr, holding broke pedal depressed.
b) Allow fluid to flow until no bubbles appear
in tube.
Then tighten the bleed screws.
Release brake pedal.
c ) Remove tubes. Check the bleed screws for
leaks by depressing the bloke pedal to
fullest extent. I
Fit rubber protectors.
Stop engine.
5. Refit rear wheels and detachable panels.
Lower vehicle to ground.

II. BLEEDING THE BRAKES ON ESTA ,TE VEHICLES (- 0 ,970 )
A. BLEEDING THE FRONT BRAKES AND THE AIR
CHAMBER ( 1)
NOTE
This bleeding must be carried out with no
pressure in the system
in order to avoid any emul-
sifying of the liquid. and consequently the possible
formation of air bubbles in the system.
1. Release pressure in the system :
a 1 Raise front of vehicle ( wheels free ).
b ) Slacken release screw (3 ) on $ressure requlo-
tor. Remove the front wheels.
c 1 Place on each bleed screw ( 4 1 a transparent
tube wi!h its other end in a clean container
d ) ,Mnir,lnh, brnk L p&d /u//y d<~pwss,~d. and
slacken bleed screws (4 ).
e) Remove air chamber ( 1). Place a transparent
tube on the end of pipe (2 ).
2.
Bleed the br.kes :
a) S/or/ ~v,gir,c,. C id/ivg spevd I md vrnialni,r
hrnk L firdnl. tullr d,~pwss<~d
b) Tighten release screw on pressure regulator.
and let fluid flow until there are no more air
bubbles in the bleed tubes.
Then tighten the bleed screws.
c) Release broke pedo1, and remove bleed tubes.
d) I:;/ nir rhnmhrr ( I ) nltcr hnr~htg /dorm i/

e ) Check bleed screws and air chamber ( 1) are
properly sealed
by fully depressing brake pedal.
Stop engine. Place rubber protective caps over
bleed screws.
f 1 Fit front wheels and lower vehicle to the ground
B. BLEEDING THE REAR BRAKES
3.
Bleed the rear brakes :
a 1 Raise rear of vehicle ( wheels free ).
Remove removable panels and rear wheels.
b) Place manual height control lever in c high
posi~im H ( Release screw on pressure regula-
tor tightened 1.
c) Place on each bleed screw ( 5) a transparent
tube with its other end in a clean container.
Slacken bleed screws (5).
d) nlfliuiniv broke pcdfll ~yrrlly depwssvd. ar,d s/or,

e) Let fluid flow until it is free of air bubbles.
Then tighten bleed screws.
Release brake pedal.
f ) Remove bleed tubes.
Check bleed screws are propeily sealed by
fully depressing broke pedal.
Fit rubber protective cops.
Stop engine.
4. Fit rear wheels and removable panels
Lower vehicle to the ground.

1.
Raise front of vehicle ( wheels free ).
Remove front wheels.
Release handbrake lever to maximum extent 2. Adjust eccentrics :
a) Remove adjustment nuts ( 1 ) and lock-nuts (2.)
for handbrake cables.
b ) O,,,‘varh hmokt~ ,,rzit :
Slacken SCI~WS (4) of eccentrics ( 6 ). Ensure
With spanner 6501-T turn eccentrics as shown f rrpu,ards ) until the pads just contact the disc
at point of maximum run-out.
Tighten screws (4) from 6 to 6.5 daNm (43 l/2
to 47 ft.lb ).
Check correct contact of pads.
Screw down stop SCI~W (3) until it contacts
the brake unit housing ( tighfrn its lock EN! 1, 3. Adjusting hondbrake control cables :
, On rnrh hrnkc ,,,, if:
Ensure correctly positioned.
Pull alfcmnf~~iy on each threaded end-piece (7 )
ond measure its protrusion (< c 1).
.Example : Protrusion on right-hand side = 30 mm
Protrusion on left-hand side = 26mm Difference in length of cable must remain the
some after adiuitment.

Screw down cable adjusting nut (2) against
lever ( 1) Tighten lock nut ( 3) to 1.5 doNm ( llft.lb)
4. Checking tie handbrake :
Operate handbrake lever several times.
Check that adjustment does not change and that
locking system operates satisfactorily.
5. Refit front wheels : Tighten screws from 6 to 8 daNm ( 43 l/2,
