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 is 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).

Brake caliper

DISMOUNTING

Loosen the front wheel attachment screws.
Lift the vehicle by means of a two-column

elevator

Dismount the wheel.
Drain the brake fluid from the reservoir
Remove the locks and the caliper wedges.
Unscrew the rigid duct screw from the

brake flexible hose and detach the caliper
assembly.

REMARK :
If  it is necessary to dismount the

caliper fork, dismount the attachment
screws on the caliper fork.

When remounting the fork, replace the

Grower washers, tighten the screws to the
required moment of 6.5 daNm then seal
them with FIXAMED R 58.

REPAIRING

Dismount the protection gasket.
Extract the piston using a wooden wedge and

a compressed air source.

Remove the sealing gasket from its seat in the

caliper groove by means of a blade.

Clean with alcohol the parts, replace the

damaged ones, mounting being performed in the
dismounting reverse order, after previously all
parts have been oiled with brake fluid.

REMARK :
Before remounting on the fork, check the

sealing of the assembled caliper.

REMOUNTING

Perform the dismounting operations in the reverse order plus the following operations:

- filling of the caliper with brake fluid in order to facilitate the brake system purging;
- purging the brake system.

BRAKE CALIPER SEALING CHECKING

Connect to the caliper, a pressure gauge attached to a compressed air source.
Place a wooden wedge in order to block the piston
Create a  0.3 bars pressure in the caliper
Dip the caliper into a vessel with alcohol.
Move the piston several times to remove the air from the sealing gasket seat.
Check the sealing at various pressures, without exceeding the pressure of 2 bars.
If the brake shows air leaks by the piston, perform its dismounting.
Replace the piston, the gasket, or the caliper body, as the case stands.
Perform again the sealing test.

DISMOUNTING

Loosen the front wheel attachment screws.
Lift the vehicle by means of a two col-

umns elevator

Dismount :

- 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.

REMOUNTING

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).

Dism ount the brake disk. Before

remounting, check :

- the wear of the brake flexible hoses;
- the wear of the brake pads and

replace them if  necessary.
