Oro K24's - 'bubbling air' sound from front lever?

Noticed when working on the bike yesterday that the front lever when pulled causes a short noise like air bubbling in the lever. It's only audible up very close. Lever feel hasn't changed in weeks though and the front brake would stop a bus but it might explain the problems I've been having with alignment.

Any ideas?

Thanks

    Not sure how the Oro lever and 'master cylinder' work, but there will be an air pocket in there somewhere (behind a diaphragm probably) and that expands as the piston pushes fluid to the front brake calliper, so probably what is causing the noise and all normal.
