Brake booster

[Mel]

Suddenly, the idle is a bit rough which smooths out with the brake depressed part way but then gets rough again when depressed fully.  At the point of smooth idle, there is a noticeable (screeching) air leak which I can't pinpoint exactly but I believe is coming from the booster.  And extra effort is required for braking.  No vacuum leaks between the manifold and the booster.  I'm pretty sure the booster is not working.  Any thoughts/experience?  And, any recommendations for a rebuilder.

Thanks in advance.
