BRAKE PRESSURE CONTROLLER
NOTE
The brake pressure controller is not to be repaired.
DISMOUNTING
Drain the circuit, recover the fluid;
Detach the four connections (1) of the rigid pipes.
Dismount the two M6 attachment screws of the pressure controller support on the floor (2).
Remove the support together with the pressure controller from the fixing clips.
Dismount the pressure controller off the support.
REMOUNTING
Mount the pressure controller attachment screws on the support.
Attach the support-pressure controller assembly on the floor.
Mount : -control lever
- the four connection screws of the brake pipes
Purge the braking circuit and adjust the pressure controller.

The working principle of this control is similar to the one of a brake control, having the same
wo rking fluid : SA E J 1703 DOT 4.
TRANSMITTER CYLINDER REPLACEMENT
DISMOUNTING
Disconnect the battery.
Drain the clutch control hydraulic circuit ; for this purpose, open the purging connection and
connect to this a transparent hose for draining. Dismou nt :
- dashboard lower pa rt ;
- the feeding pipe 1 with brake fluid from the reservoir;
- the hydraulic pipe of the transmitter cylinder 2.
Detach the cylinder rod from the control pedal bolt (dismounting effort : min 5 daNm ).
Di smount the transmitter cylinder 3 as follows: by means of 24 mm wrench, rotate the
transmitter cylinder from the right to the left aprox. 45 ° and extract the cylinder ( dismounting
moment : min 0.2 daNm ).

REMOUNTING
Perform the dismounting
operations in the reverse order ;
-tr ansmitter cylinder mounting moment on the support – max 0.5 daNm
- cylinder rod mounting moment on the pedal bolt – max. 5.0 daN
Refill the brake fluid reservoir and purge the clutch control circuit by means of the purging
connection. Adjust the level in the brake fluid reservoir.
At t ent i on
When remounting the feeding pipe at the brake fluid reservoir and at the
transmitter cylinder, observe the positioning markings.

HYDRAULIC RECEIVER REPLACEMENT
This operation shall be performed after dismounting of the engine-gearbox assembly and after
disconnecting of the engine from the gearbox.
DISM OUNTING
Dismount the two attachment screws and dismount the hydraulic receiver.
REMOUNTING
Perform the dismounting operations in the reverse order.
Tighten the screws at the required moment of 2.1 daNm.
PHYDRAULIC CIRCUIT PURGING
1. CIRCUIT REFILLING
Check if the clutch pedal is in the “up” position, maintain it by hand if necessary.
Fill the reservoir with brake fluid.
Remove the protection cap of the purging connection 1.
Connect a transparent hose a t the purging connection to recover the brake fluid.
Retrieve the clip 2 (do not definitely remove it in order to limit the movement of the feeding
pipe).
