Brake flexible hoses
IMPOSED PRECAUTIONS TO BE RESPECTED WHEN
DISMOUNTIN G – REMOUNTING A RECEIVER
OR A BRAKE FLEXIBLE HOSE
Due to security reasons, in order to avoid brake flexible hose twisting and the risk to get i n
contact with the suspension elements, it is necessary to observe the following operations sequence,
as well as the flexible attachment on the wing lining by means of a stopper, positioned at 135 ± 2
mm, value to be measured from the connection screw of the rigid pipe with the flexible hose.
DISMOUNTIN G
Dismount the connection ( 1) of the rigid pipe (6) from the flexible hose ( 2) till the moment
when the spring (3) is relaxed, having releasing the splinted area (4) of the sustaining support (5).

Brake flexible hoses
Unscrew t he flexible from the caliper and after that from the connection with the rigid pipe.
REMOU NT I NG
Assemble the caliper with the caliper fork.
Mount the caliper wedges and then tighten to the required moment the flexible on the caliper.
The flexible hoses must be tighten to the required moment with the rigid pipes, when the front
axle is in the position :
-symmetric wheels (mounted suspension );
- front axle in straight line.
REMARK :
Position the hexagonal area (4) of t he flexible in t he sustaining support (5) so that
it is not mounted twisted. Mo unt the spring (3) and the connection of the rigid pipe on the flexible hose,
observing the required tightening m oment. Purge the brake circuit.

ADJUSTMENT OF TH E BRAKE PRESSURE CONTROLLER FOR
THE PARALLEL BRAKING SYSTEM
Imposed conditions : -the vehicle on wheels
- empty trunk
- one person on board
ADJUSTMENT METHOD
Mount the flexible connection of the FR 501 device at the purging screw of one rear wheel
cylinder. Purge the manometer.
Push the brake pedal to enable reading several times the limiting pressure obtained on the
rear wheels cylinders.
Unscrew the adjustment nut ( A) to distance it from the pushing rod end (B ).
A ct upon the rod end ( B):
- by unscrewing it towards the pushing rod ( C ) in order to increase the pressure in the
rear circuit;
-by screwing it towards the pushing rod (C ) in order to decrease the pressure in the rear
circuit.
Tighten to the required moment ( 0.15 damn) the adjustment nut (A) locked with the pushing
rod end ( B) so that between the lever end a nd the lever ( D) a c learance of L = 0.5 mm to be
ensured.
