You can just use a 7mm box end wrench (or is it 6mm I always forget).  One of
the guys on the list posted a nice idea a little while back about using a
piece of hose attached to the bleeder screw with the end submerged in a
container 1/4 full of brake fluid.  The container collects the fluid and
allows you to pump the tar out of the breaks without getting air sucked back
up into the lines.  Just be sure to keep your reservoir topped off.  This
idea is great because it is:
1. Simple
2. Cheap
3. Easy to do as a one man operation.
4. The materials for it can be easily obtained at any Walmart or Home Depot.
Hope this helps and thanks to the List member that posted this idea a couple
months ago (I would openly praise you but I forget who it was honestly).
