Go to harbor freight and plop down a measly $25 or so (think new to me tire price) and get a MIGHTY VAC - yes they sell them. Do not spend $5 less and get the no name brand.
Look at the You tube videos of them bleading brakes with it as well as cleaning out master cyl. etc.
You will be going Uhhh, ohhh, ahhh for days.
