Checking the brake pads wear
Point of view construction, the front brake is a ventilated disc type with floating caliper and
fork (1) attached by means of the screws to the steering knuckle.
Brake linings ( 3) ( brake pads) are “TEXTAR“ type, without wear sensor.
The wear checking i s performed by comparing the mark ( P) from the caliper, with the ( C)
mark from the fork
Maximum wear of the brake lining (brake pads) is token into consideration and their obligatory
replacement is imposed, when the protuberance ( P) from the caliper ( 2) is as seen in “D” close-
up, against the middle of the channel “ C” from the fork (1).

DISMOUNTIN G
Loosen the front wheel attachment screws.
Lift the vehicle by means of a two col-
umns elevator Dismou nt :
- the wheel;
- the two attachment screws (A) of
the brake disk assembly on the steering
knuckle ; -the two sunk screws (B) attaching the
disk on the hub.
Brake disk
REMARK :
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 0.04 mm on a diameter of Ø 215.

Remount :
- the disk on the hub by means of the two
sunk screws (B) and tighten them to the required
moment; - the brake disk assembled on the steering
knuckle, tightening the ( A) screws to the required
moment. Press the brake pedal several times, in order
to bring the piston in contact with the brake pads.
REMARK :
In case of replacing the brake disk it is
absolutely necessary to replace the brake
pads ( TEXTAR brand).

Continue by dismounting t he steering
knuckle, observing the operations sequence: - dismount the steering ball joint nut;
- depress the steeri ng ball joint by
means of the PF 476 extractor;
- dismount the two screws that attach
the steering knuckle on the shock absorber
leg;

DISMOUNTIN G
Dismount the steering knuckle (see method
“Dismoun ting steering knuckle).
Remove the safety ring ( bore ring) from the
interior of the steering knuckle.
De pre ss t he biconi cal be a ring, usi ng a
→ 50 mm outer diameter rod.
P lace t he steeri ng rod using a bushing with
inner diameter → 67 mm.
R EMOU NT I NG
Introduce in the steering knuckle the bearing
support washer
Press the bearing in the steering knuckle, by
means of a → 63 mm diameter bushing.
Mount the safety ring in the channel of t he
steering knuckle bore.
REMARK:
The operation shall be performed so that
bushing is not pressed on the bearing
support washer, in order to perform a correct
mounting and not to damage the bearing. The steering knuckle-bearing assembly
is
to be placed above the hub and after centering
the support washer, press the bearing on the
hub, using a bushing with the inner diameter
of Ø 36 mm and an e xteri or diameter of Ø
40 mm. Continue with the mounting of the steering
knuckle assembly on t he vehicle (see the
method “ Remounting steering knuckle ”)
REMARK :
When replacing the bearing, its spacer
is also t o be obligatory replaced.

Chara cteristics
The rear axle is composed of an axle having a “ U “ shaped torsion profile to which arms are
welded For the transversal stability and the resistance fatigue improvement of the cross- bar, the axle
is equipped with a Ö 21-mm diameter stabilizer bar. The bar is inserted by welding on both ends
in the axle side arms. The connection of the axle with the chassis is realized by elastic bushings of the spiral spring
and the double effect telescopic shock absorber. The drum and the hub constitute a common body, and are mounted on the steering knuckle
by means of a be-conical sealed bearing.
