Tiiiiineeeeeee Bubbles.....................
What a fukkin bitch.....................bleedin these gawd dambed Galfer brake lines. After anouther friggin hour and 3/4 of a bottle of brake fluid I still get the odd tiny bubble every once in a blue moon. I think the thing is almost there! Unless now my hands are stronger than before as I can still pull the lever to the grip (more pressure it seems though) How about anyone else? The thing stops way better, but what, and how hard should it get?

Jeeze, Rubber -
it took me 15 minutes a side.
Don't open the bleeder valve until you put pressure on. Close it before you let up (duh).
After a bit of bleeding, stop and wait five minutes. Then tap the caliper at the banjo bolt, the upper and lower mounting bolts, and on a place you don't think will show for ten or so taps each - use your 12mm boxend...
My brakes are really really sweet, and I did mine last night, see my thread here.
OH - almost forgot (hence the edit), mine took about five pumps of the lever when I was done to build up lever firmness - then I was done; I am seriously pleased with mine.

What kz2zx did is one of the best ways to cap off a bleeding operation. The secret is to "bleed" it at the lever. After you get done doing the squeeze/release thing at the caliper bleeders as well as you can, you get the balance of the air out by slightly pulling/releasing the lever and watching those bubbles magically appear through the master cylinder resorvior. Just little pumps and snap releases on the lever. You will be amazed at how much air will come out and how hard the lever will get. Leave the cap off the resorvior and watch it. Make sure you put a rag/towel around the tank and such in case you pump too hard and fluid comes up out of it. The idea is small movements that will get the air coming up to the highest point, which it naturally wants to rise anyway. Stay after it and be patient and you'll be rewarded with maximum pressure and no air at all. Because a lot of times, even with a Mitivac, it just can't force all the tiny bubbles out such a long path.

Ya ... thanks you guys!!
I might be too picky here but did exactly what you did. I guess you will always have a little air there no matter what!?

Nope, don't have to have any air. Just stay after it. It does take some patience.

The more I squeeze mine, the harder it gets.

I think I have some air in my system.
I have been so busy moving into a new house and working a ton at the same time.
I do not even know where my tools are at.
I think I will bleed it some more this week.

Air collects in the banjo fittings and can be a real bizatch to remove. Doing all three is overkill, but you most definitely want to do the master cylinder. Wrap a rag around the mc banjo and, while squeezing the lever, loosen the banjo bolt till fluid (and trapped air) escapes, then quickly retighten. Be certain to have plenty of catch rags under the fitting, on the hose... Did I mention some fluid will escape? I have seen this work where ALL else has failed. Banjo bolts with bleed nipples are available for this also. Some people believe putting a bungee, etc. on the lever overnight will allow some air to find it's way out through the master cylinder. That adds to lever firmness but only, imho, because it seats all the pistons/pads against the rotors.
