5-20 BRAKES
VACUUM CIRCUIT CHECKING
Circuit checking
1) Do a trial on road and verify that help towards breaking is
enough.
2) If help towards breaking is not satisfactory, disconnect sleeve
(2) from brake booster (3) connection and fix vacuum meter
in series point (A), as seen in the drawing.
3) With engine at 1000 rpm check if the press vacuum reading
is near to specified.
Vacuum pressure: 850 mbar
Otherwise, check:
• Eventual leaks through the vacuum sleeve (2).
• Eventual blockage of depressor exit (1) or breakdown in it.
• Eventual leaks in the brake booster (3).
• Eventual leaks in the vacuum tank (4).
Locating leaks and breakdowns
4) Connect a vacuum meter to vacuum pump and carry out
checking as explained in task -3-.

5) If it is no correct, the depressor is faulty. If it is right then do
as follows:
• Connect vacuum sleeve (2) to depressor (1).
• Disconnect sleeve (2) from connection to brake booster
