The amount needed is truly miniscule and the problem is often difficult to trace.
This is most noticeable after stopping since that is when the booster is used.

If your brake booster is letting fluid from your master cylinder, (in any amount) into your engine, you have much more serious problems than a little white smoke..

Especially considering that this would mean that your master cylinder's main cylinder seals are leaking, and blowing fluid back into the brake booster (a separate component), which is then being sucked through the vacuum booster line into the engine.

What this means, is that eventually, you're going to run short on brake fluid, and die. So yeah, you might wanna check on that.
