What does that small cannister do, that sits in the rubber vacuum line from the brake booster to the engine manifold?
My mechanic removed it, saying I didnt need it.. But I still have it.. Should I put it back on?

Pretty sure its a check valve. So vacuum wont go back out of the booster. If your engine keeps good vacuum when its running, then no you dont need it, but I dont see why he would take it off, unless its broken.

it is a filter so the crankcase fumes don't get into the booster and deteriorate the diaphram.

I wasn't aware there was a filter inside it but I do know it's a check valve. If the engine dies while driving, the check valve will hold vacuum in the booster for a couple of power assist brake applications. Once the vacuum is gone, braking becomes very difficult.

It should be a filter, the check valve should be the little plastc piece on the booster.

Oops. I stand corrected. The check valve is the piece that goes into the booster.
It's still a good idea to use the filter.
