Doing my fronts this afternoon. I bought a mityvac to run off my compressor. I'm assuming the principle is to bleed all three valves top to bottom, by creating a suction and pulling air outta the valves, while making sure I have fluid in reservoir. Comments anyone?

Do you think that you have air in the system? If not, as Jim said above, you don't need to mess with the top bleeder.

Yep, that is how you do it Will. Start high and close to the master cylinder and work your way down and further away. Three bleeders on the brakes, and two bleeders on the clutch.

My experience is that it takes a LOT of bleeding to purge the systems on a C-14. It is easy to do with the powered bleeder but it might take a lot of brake fluid. Once you get all the old (not clear) fluid out of the system, you can empty and clean the bleeder container thoroughly and then re- use the new brake fluid after it is pushed through the system. Brake fluid is pretty obvious as to whether it is good or not- if you cannot see any debris in the fluid and it is clear, it is good fluid and fine to use. As it absorbs moisture and deteriorates it will turn darker and darker; I change mine before it gets to something like caramel color.

My suggestion would be to keep bleeding the system(s) until the pedal or lever is firm and there is no take- up travel at all left. You really cannot tell if the last of the air is out of the system by watching the fluid leave the bleeders because the bleeders themselves leak a small amount of air into the brake fluid stream anyway; you won’t be able to tell if any of that air is really coming from inside the hydraulic system itself.

Ok, so it sounds a bit odd, but I have my wife's old breast pump that I was thinking of trying to convert into a power bleeder.  When I move forward with this project, I'll keep you abreast of the progress...

Sounds like it could turn into a titty sticky situation.

If the breast pump is causing dual bleeders I'd suggest only doing one at a time and in moderation...  :-\

I'm no exspurt, but I've played with this idea as well.  After much thought, much looking, and many beers, I decided that the amount of vacuum that a breast pump produces will make the process VERY slow.  OOOOOOOOOOOOh, just thought about this as I was writing.  Run the pump THROUGH a small canister (reservoir) so you could build constant vacuum.  Put a valve on the bleeder end of the hose so you could manage the suction.  Damn, see I didn't have enough beer!  I'm thinking pretty clearly now....I think!
