Hissing noise from BRAKES

When I switch off the engine and use the foot brake, I get a hissing noise when either depressing the foot brake, or allowing it to return to rest position. This happens for about 3 depressions, then returns to the normal braking pattern. Does the brake reservoir also swerve the clutch actuation ??? 1.8 VELOCE 2001. ?????

The hissing is prob coming from the brake servo witch is powered by vacuum from the engine. Mine did it too, i think it's just air leaking past the gator on the rod to the servo/master cylinder.

And yes the brake reservoir is also serves the clutch too.
