I've always found that when the engine dies when braking, it is either a leak somewhere around the manifold or the float level is too high. Seems wrong and it took me a while to accept it but the guy who told me was right.
So, what to do? You say the manifold is sealed up tight but I'd still check it. With the engine idling, spray starting fluid around it and listen for a change. If that is all OK, try putting a washer under the float valve, thus lowering the fuel level. Go for a drive and test it.
Please report back when you get it right so others can learn what works.
