If some does escape it's horrible stuff you don't want knocking about inside your frame, and some will almost certainly escape unless someone has started making frames with internal routing that isn't a pain in the arse and you happen to have one. Get a bleed kit (http://www.epicbleedsolutions.com) and do it that way, it's worth having a go so you have an idea about what you're doing if there are any problems. If in doubt push fluid backwards and forwards, tap things and squeeze the lever randomly until it all works.
