PREPARING THE VEHICLE
•
It is important to ensure that there is always a sufficient quantity of brake fluid in the tank.
•
These operations may be simplified by using a bleeding device when carrying out the "Re-
placing the brake fluid" operations
•
In this case, when performing the bleeding procedure, it is also necessary to operate the
brake pedal a few times with the bleeder device connected (approximately five times for
each wheel circuit).

FRONT/REAR BRAKE MASTER CYLINDER

PRELIMINARY OPERATIONS
•
Replace the damaged brake master cylinder with a new one
•
Connect the brake line to the new brake master cylinder

•
Top up and refit the cap
•
Check the stroke and sensitivity of the brake pedal and lever
•
If the brake pedal or lever stroke is too long after carrying out the bleeding procedure, check
the braking system for leaks and, if none are found, bleed the system using the diagnostic
tool, as described.
•
Disconnect the flexible bleeder pipes and re-tighten the bleeder screws, applying the correct
torque

BLEEDING SYSTEM WITH DIAGNOSTICS INSTRUMENT

This type of bleeding has to be carried out if after all the checks the brake lever and the pedal
are still spongy.
The operations described here are valid for both systems even though the description refers to
the front system.
