REMOUNTING
Before remounting, check:-the a djustment of the main cylinder
stroke, which is obtained by acting on the pushing
rod nut in order to obtain value X= 9mm,
between the pushing rod end and the rest surface
of the main cylinder.
-the adjustment of the coupling fork on
the brake pedal side, which is obtained by
unscrewing the lock nut E and by acting on the
coupling fork i n order to obt ain the value L =
1 17 + 0,5 mm.
Fo r remounting, perform the dismounting
operations in the reverse order.
Purge the brake circuit.

The tightness of the servobrake is checked on the vehi cle, with the hydraulic
circuit under operation.
Connect the vacuum meter between the servobrake and the inlet collector by means of a “ T
” type connector. The connecting hose of the vacuum meter shall be as long as possible.
Start the engine and let it idle run for 1min.
Block the air suction hose by means of the MOT 453 device.
Stop the engine.
If air suction lowers with more than 33 mbar (25Hg) in a 15 seconds period, it means there
is a loss at t he retainer valve (replace the valve) or at t he servobrake m embrane (replace t he
servobrake) Dismount the MOT 453 device
