I did something new while flushing the brakes on my dad's car yesterday. I hooked the mityvac up to the bleeder - opened the valve - pumped a few times on the mityvac - pumped on the brake ten times - closed bleeder with line still on. No problems with air in lines. Gravity or the mityvac itself wasn't good enough to get the fluid to move. Before I always had a helper.. as long as the line stays on should be okay.
Flushing my own brake fluid?

When I use my Motive pressure bleeder, I also pump the pedal gently (and not all the way down) a few times to get things going. There's plenty time to make it to the bleeding nipples (!). No helper needed.
I use Griot's Garage "pump and suck" brake bleeder. When you pump it up, it builds up vacuum.
First, use it to replace the fluid in the master cylinder.
Then, starting from the pass rear brake, attach the hose from the bleeder to the brake and let suck the old fluid out. Keep replenishing the fluid in the master as you go.
Do all 4 wheels from the furthest to the closest, finish topping off the master cylinder and call it a day.
Been using one for 10 years now with no problems.
On the Bimmer I use a Motive pressure bleeder pressurized to 15 psi to bleed it.
Both are great devices for bleeding / flushing brakes.
Cheers!

I just made my own pressure bleeder out of $25 worth of parts. Will test it out this weekend when I have time to play.
KS, google "homemade brake bleeder" and you will have hours of fun reading. Here is one good example:

I use a MityVac to bleed brakes. It works just fine. I swapped out the old stuff in our 70 MGB and my old 98 Grand Prix that way. I have yet to tackle my MazdaSpeed 6 yet.
Will post pics and parts list in the "tools" section once I get the bugs worked out. Still a hurdle or two to overcome.
