Remarks: the vehicle is equipped with the master cylinder that is integrated with the servo brake. The servo

brake sealing is directly associated with the master cylinder. It is necessary to substitute a new washer (A)

when in repair. The master cylinder shall be placed in parallel to the servo brake, so that the pushrod (P)

can accurately and directly move into the master cylinder body.

Reconnect:

– The pipes near the marks made when they were previously removed.

– The compensation tank by pressing to make it well stuck in the master cylinder.

Clean the brake line.
