bench bleeding
here's the story, i've finally got the m/c set on the booster and the ill fitting brake lines (ecklers) rebent so every thing lines up. i want to remove the m/c and do a bench bleed before i use my motive pressure bleeder.
after i bench bleed how do i prevent fluid from leaking out of the ports while i'm attaching the brake lines? just ignore a few drops or will it gush out and introduce air into the line? also, in the time it takes to hook up the pressure bleeder, will the fluid continue to drain out of the m/c, or by keeping the bleeders on the calipers will the air in the lines prevent this? i'm using dot 5 and don't want to do this twice-that junk isn't cheap!

It's not going to gush out or anything. It needs pressure on it to come out the ports. It will obviously have some fluid there just because of the bench bleed, but it's not going to go everywhere on you. You'll like the motive bleeder. I just got one this week and put it to use. One of the best things since sliced bread.

You can take the brake lines off and bench bleed with the pedal. It has worked for me just hook up the plastic lines and go for it. Save some time. You should get a full stroke if the rod is adjusted correct and if it is adjustable.

I really don't think you need to bench bleed....
with the pressure bleeder.
I've bench bled, and not bench bled, when using a pressure bleeder; and it did not seem to make a difference.
One thing I was able to do with the pressure bleeder, which I would have otherwise never done, and completely change my brake fluid...it is so easy to use, that I just kept bleeding until it came out completely clean at all the caliper ends.

From: TEXAS - you mean there are other states?
With this pressure style of bleeding it seems much easier... the only possible negative might be that you may use more fluid to achieve a full purge when bleeding the master cylinder while on the car
