Di sconnect the wiring c onnector from t he
reverse driving contact. The right-side planetary transmission is un-
coupled as follows:
-the brake-stirrup set is dismantled;
-disconnect the wire for the brake pads
wear indicator; -the t wo screws for fixing the shock-
absorber of the steering-swivel stand are taken
off;
The steering-swivel stand is tipped up and
the planetary t ransmission is taken out from
the planetary pinion of the gearbox;
The l eft-side planetary transm ission is un-
coupled as follows:
-the steering-swivel screw-nut is dis-
mantled; -t he scre ws for fi xi ng t he pl a neta ry
transmission on the gearbox a re taken off; -the brake-stirrup set is dismantled;
-the e lectric wire of the wear-and-abra -
sion light-i ndicator is taken off; -the t wo screws for fixing the shock-
absorber of the steering-swivel stand are taken
off; -the steeri ng-swivel stand is t ipped up
and the planetary tra nsmission is taken out; The fuse-box in the engine compartment
is dismantled.The following are disconnected: -connector 1 from the UCE injection
(pull flap 2, then disconnect);
-the front cabling of the engine;
-the connector of t he shock-sensor;
-the ventilator connector;
-the mass wire on the gearbox.
The battery protection screen is dis-
mantled.
The following are taken off:-the linking pipes coming from the ra -
diator, by using the pincers for elastic pipe-
collars MOT.1202-01B ;
-the linking pipes coming from the de-
gassing vessel, by using the pincers for elas-
tic pipe-collars MOT.1202-01B ;
-the pipes for a ir-conditioning coming
from the therm ostat stand and the water-pi pe;

FRONT TRANSVERSAL TRANSMISSION
REMOUNTING – THE SIDE TO THE GEARBOX
The left side
Engage the t ransmission GI joint in the ge arbox (the transmission position as horizontally
as possible).
Mount the thre e attachment screws of the bellows lid on the gearbox.
The right side
Grease the t ulip fra me grooves (the grooves area) and t he tra nsmission shaft of t he
gearbox with transmission oil.
Engage the transmission GI joint (the tulip) on the transmission shaft of the gearbox
(the tra nsmission position must be as horizontally as possible).
REMOUNTING – THE SIDE TO THE WHEEL
For both sides
Engage the transmission in the steering knuckle, this one being necessary to freely enter,
so that threaded area of the steering knuckle is allowing to remounting the transmission nut.
Pe rform then the dismounting opera tions in the reverse orde r.
Ob serve the tightening moments.
Remount the brake disk assembly.
Refill the gearbox with oil.
Pr ess several times the brake pedal to enable caliper piston coming in contact with the
brake pads.

I. FAILURE : RIGID PEDAL (ctd)
On e o f th e
rigid brake
pipes is it
smashed ?
Dismount the bra ke caliper or
the brake cylinder?
Replace the corresponding
rigid pipe.
Are the brake
caliper’s pistons
or the cylinders ones correctly gliding ?
STOP
Replace the defective parts
(with Genuine Spare Parts)
Replace the brake pads,
consequently the bra ke shoes (see bellow situations).Are the brake pads,
consequently the shoes
gasket in good
condition?
The brake linings are to be replaced when
they are: -greasy
-shiny
-not in accordance with the
manufacturer ’s prescriptions (genuine Spare
Pa rts have not been used).

BRAKE FLUID
PERIODICITY OF THE BREAK FLUID CHANGE
The manufacturing conception of the brakes equipping the Dacia vehicles, especially
the di sks brake type (F 54 inner empty pistons, low qua ntity of fluid in t he c ylinders,
sliding calipers avoiding existence of a fl uid reserve in the less cooled area of t he wheel)
enable t he m aximum re jection of fluid vapori zation ri sk, even in c ase of intensive using of
brakes (mountain are a). The current bra ke fluids are subject in all cases to a slight degradation during the fi rst
months of use by a slight humidity absorpt ion seri es (see the Vehicle Warra nty and
Maintenance Booklet, for brake fluid change)
LEVEL COMPLETION
The wear of brakes pads and shoes generate a gradually diminution of brake fluid level
in its reservoi r. It is useless t o compensate t his diminution, because the level will be re -
stored in the moment of next changing the brake pads and shoes. Obviously, in the mean-
time, the level of brake fl uid in re servoir must not go down bellow the minimal mark.
HOMOLOGATED BRAKE FLUIDS
The mixture i n t he bra king circuit of two non compatible brake fluids may leads to loss
important risks mainly due to gasket damage
In order t o avoid such risks, it is obligatory t o use bra ke fluids checked and approved by
our laboratories and which are accordi ng to Norm SAEJ 1703, DOT 4.

BRAKE GASKETS
NOTE
In order to maintain the brake efficiency,
the replacement of the brake pads shall be
made only in complete kit.
Never fit brake pads of diffe rent makes
and different qualities .
DISMOUNTING
Lift t he vehicle by means of a two columns
elevator;
Dismount the front wheel;
Disconnect the wear sensor wire;
Dismou nt : - the safety of the wedges (1);
- the wedges, by sliding them.
Detach the caliper assembly from the fork
together with the flexible hose;
Remove : - the elastic blades - the brake pads
Remount :- the brake pads their places in the fork;
- the elastic blades;
- the caliper;
- the wedges and their locks.
Reconnect the wear sensor wire.
Pr ess several times the brake pedal.
Mount the wheels.
Get down the vehicle from the elevator the
ground. NOTE
It
is forbidden to push the brake pedal
after the calipers were dismounted from
the fork. If the brake pads are not fully used but
on their friction surface, especially i n the
middle pad c hannel, there are material
traces, i t i s recommended t he cleaning of
these surfaces in order to avoid the noise
when braking.
REMOUNTING
Push the c aliper pi ston by means of the
FR 500 s pecial t ool.

DISMOUNTING
Lift the vehicle by means of a two col-
umns elevator.
Dismou nt :
- the wheel;
- the two attachment screws M 12 ( B)
of the brake disk assemb ly on the steering knuckle;
- the brake pads;
- the t wo sunk screws attaching t he
disk on the hub. BRAKE DISK
The brake disks can be not rectified.
A bigger wear or an important mark on the brake disk braking surfaces impose obligatory its
replacement.
- The minimal accepted thickness : 19 mm
- The maximum accepted axial deviation 0,1 mm on a diameter of F 215.
TIGHTENI NG MOMENTS (daNm)
steering nuckle 6,5
Disk attachment screw on the hub 2,5
Front wheel steering knuckle nut 21
Wheel screws 7,5
Before remounting, check:
- the wear of the flexible hose;
- the wear of the bra ke pa ds and
replace them if necessary. REMOUNTING
Remount :
- the disk on the hub by means of the two
sunk screws M8 and tighten them to the required
moment; - the brake disk assembly on the steering
knuckle, tightening the M 12 screws at t he
required moment. Press the brake pedal several times, in order
to bring the piston in contact with the brake pads.
NOTE :
In case of replacing the brake disk it is ab-
s olutely necessary to replace the brake pads.
