I think I mentioned this before, no need to buy expensive brake bleeders (and I have bought a few). Jut get yourself a cap that fits the master cylinder and it is airtight (may be a spare cap), put a hose in it with a foot pump fitting and connect that to your wheel closest to the reservoir. It will bleed everything like a champ. Just be careful when undoing the nipples, don't take the spanner off and be ready to close the nipple otherwise you'll shoot all your brake fluid out in a matter of seconds. And keep an eye on the fluid level in the reservoir so you don't run it dry.
This is the only way I managed to reliably bleed brakes after installing new master cylinders because the air pressure pushes the fluid too quickly for the air bubbles to fight so they get pushed out even form the high spots.
There should be no measurable loss of air pressure in the tyre too because all you draw is a volume equal to the space above the fluid in the reservoir. I put a little plastic irrigation tap in my line so I can turn off the pressure without having to disconnect from the tyre in case I need to top up the reservoir or whatever.
