Dismount the two maintaining collars off
the bellows by means of two rods, locally
manufactured (see the drawing)
Cut and remove the damaged bellows.
Remove as much grease as possible.
Mark one of the groove routes of the shaft
subject to its working corresponding clog by
marking w ith a centre punch on casing outer
conse quently on the shaft.
Detach th e connection be twe en the
transmission shaft and the steering knuckle
casing, lift ing one by one the arms of the

REMOUNTING
The mounting of the new bellows is to be
performed by means of the PF 573 – 04 device.
Catch the inclined transmission in a vice with
soft jaws in order to avoid the shaft damaging.
Engage the PF 537 – 04 device over the tulip
of the transmission shaft.
O bturate the small e xtremity of the bellows
and, abundantly grease with automatic
transmission oil or ELF CARDREXA RNT 2
grease: - the all outer surface of the PF 537 – 04
device, - the inner part of the bellows, especially its
smaller diameter part (this operation is performed
for slipping help).

30Brake fluid
PERIODIC CHANGE OF THE BREAK FLUID
The m anufacturing conception of t he brakes equipping t he Dacia vehicles especially the
ventilated disk brake, enable the maximum diminishing of the fluid vaporization, even in case of
intensive using of brakes (mountain area), due to good disk cooling.
The brake fluids, suffer in all cases a slight degradations during the use, by a slight humidity
absorption, that makes necessary the complete replacement after a period of time or after some
driving (4 years or 60,000 driven km)
COMPLETION OF THE BRAKE FLUID LEVEL
The wear of brakes pads and shoes, leads to a gradually diminution of brake fluid level in its
reservoir. It is useless to compensate this diminution, because the level will be restored when changing
the brake pads and shoes.
Obviously , in the meantime, the level of brake fluid in reservoir must not go down bellow the
MINI mark.
HOMOLOGATED BRAKE FLUIDS
The mixture in t he braking circuit of two non different brake fluids may leads to important
risks mainly due to gasket damage, incompatible with new fluid.
In order t o a void such risks, it is obligatory to use only bra ke fl uid re commended by the
producer, i.e. : SAEJ 1703, DOT 4.

The influence of angles
The influence of different angles over the road behavior, stability and abnormal wear preventing
of the vehicles tires.
CAMBER
The exit from the tolerance field of the left or right wheel camber, may have as result:
- tires external or internal edge wear (excessive positive or negative camber);
- steerin g is deviating towards the camber angle is more pronounced (asymmetry ), a deviation
from the trajectory is taking place, which must be corrected by means of the steering wheel (the
pronounced wear on the tire in question is occurring);
CASTER
A larger difference of 1° between the right side caster and left side, may have as result:
- a deviation from the trajectory, which must be corrected by means of the steering wheel, the
abnormal tires wear (the pronounced wear on the tire in question is occurring), tough steering,
instability when turning.
PA R ALLELISM
This adjustment has little importance over the vehicle road behavior.
Anyhow, note the followings:
-a prominent closing may lead to tires external edges wear.
-a prominent opening may lead to tires interior edges wear.
DIMENSIONS UNDER CARRIAGE BODY
These are especially influencing the different angles of the steering geometry.
A vehicle, which has run a large amount of km, it will have under the carriage body, dimension s
smaller than a new vehicle. This is the reason why some vehicle manufacturers, are prescribing, when the checking is
done with empty vehicle, different under carriage body dimensions and their respective places
where these values must be taken. Other vehicle manufacturers are recommending the suspension
compression by means of special (specific) tools or loading repartition in different places.
These different procedures (as performing ways) have as final purpose, the cancellation of the
vehicle suspension lowering, which has driven an important number of Km, compared with its
initial condition.

Suspension ball joint
DISMOUNTIN G
Perform the same operations as for dismounting the suspension arm.
Unscrew the two attachment nuts (3) of the arm shafts, without their dismounting .
Dismou nt :
- the ball joint a ttachment screws ( 4) on the arm;
- the ball joint.
REMARK :
When dismounting the suspension ball joint off t he arm, check by visual inspection
if the corresponding holes from the suspension arm, are out of round.
If they are out of round, obligatory replace the suspension arm.
REMOU NT I NG
REMARK :
Ensure the presence of t he protection pl ate (A) on the suspension ball joint axle.
Mount the suspension ball joint on the arm, by means of the two attachment screws (4) and
tighten their nuts to the required moment.
Perform then, the same operations as for suspension arm remounting, observing the tightening
moments.
PROTECTION BELLOW S REPLACEMENT
Dismount the damaged bellows.
Clean the ball joint in the area covered by
the bellows (ball joint body and pin).
Fill the new bellows with approximate 3g
MOS
2 s pecial grease.
Mount the new bellows on the ball joint.
Place on the bellows by means of a resis-
tant thread, the fixing clip (B), then the fixing
clip A (Ø= 19).

Brake lining (pads)
REMARK :
In order to maintain the brake efficiency,
the replacement of the brake l ining (pads)
shall be made only in complete kit. Brake pads brand TEXTAR are to be used
as spare parts.
DISMOUNTIN G
Loosen the front wheel attachment screws.
Lift the vehicle by means of a two-column
elevator.
Dismount the front wheel.
Disconnect the wear sensor wire.
Remove: - the safeties of the wedges ( 1);
- the wedges, by sliding them.
D etach the caliper assembly from the fork
together with the flexible hose.
Remove:
- the brake pads from fork seats
(maintaining springs are attached with them);
- the maintaining springs from the brake
pads. REMARK :
It is forbi
dde n t o push the brake
pedal after the c alipers were
dismounted from the fork. If the brake pads are not fully used
but on their friction surface, especially
in the middle pad channel, there are
material traces, it is recommended the
cleaning of these surfaces in order to
avoid the noise when braking. Irregularly we ar of one brake pad or
wear diffe rences between t he inner pad
the outside pad, greater than 10% of the
minimum remaining l ining, impose the
kit replacement.

The replacement of brake shoes must be

brake shoes equipped with brake linings of
different brands and qualities.
Dismou nt :
- the brake drum ( see the correspond-
ing paragraph); - the t wo maintenance springs ( R) of
the shoes with a brake cylinder rod ( T). By means of the pliers
FR05A the brake cyl-
inder pistons are immobilized.
Remove the return upper spring of the shoes
using the pliers FR03.
Release the end of the hand brake cable from
the hand brake lever.

ment it comes into contact with the rear wheel

Brake shoes
Checking of t he brake shoes wear may be pe rformed also without dismounting t he brake
drums.
In this purpose:-lift the vehicle by means of a two-column elevator;
- dismount the rubber protector of the visiting window from the brake plate;
- check by visual inspection the condition of the brake shoes wear.
If a serious wear is established, perform the brake shoes replacement (see the corresponding
paragraph).
