CHECK LIST FOR ENSURING SATISFACTORY FUNCTIONING OF VACUUM BOOSTER

Engine Off :

Depress and release brake pedal several times to remove vacuum from the system.

Depress pedal and hold with light pressure (7-12 kg) and start engine.

If Vacuum Booster is operative, pedal will fall slightly and then hold. Less pressure will be needed to

hold pedal down, than with the engine in 'off'' condition.

If Vacuum Booster is not operative disconnect

the vacuum hose from the Vacuum Booster non-

return valve. Then with engine running, check

the vacuum supply with a vacuum gauge. There

should be atleast 20” of vacuum.

If Vacuum Booster is operative, do the vacuum

leak test as given.

If vacuum supply is below 20" replace or repair

the vacuum hose and vacuum fittings.

If the vacuum supply is 20" or more the Vacuum

Booster is defective and should be replaced with

new Vacuum Booster Assy.

With new hose fitting repeat the basic test.
