just don't get discouraged. you are making great progress on something complete unique. you'll get there and be happy you did. like everything done on this site, it just make take some work to get there!!!

rah rah!

and, hot , i wanna see it up and working now, after all this work you have put into it, you can't stop when your so close!!! hehe.

I was just saying that if you had the line reduced, similar to a rear disk conversion, that you would get the etra movement of the fluid needed for some extra distance.

also, the fluid won't compress at all, it is the other compents, lines, rubber gaskets and potential air in the system.

if you can get it back together, I think ensuring that all air is bled will be the most important part, just alittle air will make a huge impact on how much your final movement will be.

edit: can't type.

Thanks for the encouragement! :)

I think I'll look for the clip a bit more tonight. If I can't find it tonight, I'll check the used parts stores tomorrow. If I could find a slave with a 1" bore or smaller it would be great.

Hello :D !

EDIT: Today I got up and went right to the parts store. I found a clutch slave with a 3/4" bore. I also picked up a vacuum line and a couple tees. I teed the lines like TurboCoupe50 suggest above and ran the vacuum line to the tree. I started up the car and I got 1.75" of travel out of a possible 2" at the brake master. I got under the car and measured the full 0.5" needed on the clutch slave...and I still haven't bleed the clutch since I teed the lines.

Now I've only got two small problems to overcome: First, I need just a little more leverage with the handcontrols. When I have the clutch handle full on, I still need another 1/4-1/2 inch on the clutch pedal. Second, I need to figure out how I'm going to push in the clutch to start the car when there is no vacuum to help push in the clutch. Maybe tomorrow I'll get these things fixed and get the car back off the jack stands.

Totally stupid and uninformed stab in the dark here, but what about the whole Hydroboost brake thing from the Marks? No vacuum needed, apparently.. and while it may not be the same thing you need, I often hear a pump pressurizing the ABS system when I put the key on. Could some of those parts be adapted?

Or could you just have your vacuum pump kick on with key on? (recall you mentioning a vacuum pump before)

I had talked about an electric vacuum pump but I haven't found one yet. I think that would be the way to go. Like you said, all I would have to do is power up the pump and let the vacuum build pressure before I start the car.

I don't know how the hydroboost would be any better than I have now. Wouldn't you also have to start the car before you got boost...since it is powered by the power steering pump?

I had also thought about the ABS system but I don't know enough about it to adapt it.

Kinda pricey but it could work.

That's exactly what I was looking for but it is expensive. By the time I get it in my hands it'll cost me close to $500 or more

What I'm getting at is the possibility of using a hydroboost type system, but pressuring it on key-on like the ABS system does. It would be essentially the same thing as the vacuum boost/vacuum pump at key-on thing, but with fluid instead of vacuum. At least in the case of the hydroboost/ABS stuff, many of us should have spare parts we could send you if you went that route. (or at least I will when I tear the '88 Mark apart eventually.. and others may have the parts laying around)

Like I said, it's a completely uninformed shot in the dark.. and who knows, you're probably better off with a vacuum pump at key-on if you can find one. (a vacuum canister too? *shrug*)

i'll bet with some bleeding you can get it far enough. Make sure it is sturdy, it could suck getting stuck downtown because of a bent rod or linkage(I have had that problem in my van!). See if you can get hardend peices so they wont bend.

Now I got ya! That's a pretty good idea and it will likely cost less than the electric vacuum pump. I'll have to keep is in mind in case the vacuum stuff doesn't work out.

I plan on intensitively testing this around the neighbourhood. Hopefully, I'll have all the bugs out of the system and I can trust the system fully before I get in a tight spot. Remember, I still have to learn to drive a manual shift.

Hydroboost? $500 Vacuum pumps? Just to activate a teeny little electrical switch attached to the clutch pedal? How about bypassing it with a $1.00 push button, and making sure it's in neutral first, like the old days?

I went back at it again today. Things were going good. I bleed the line and was adjusting the handcontrols when I noticed that it was getting harder to pull the clutch lever. I discovered that the vacuum hose was collasped(sp?). I'll have to pick up another vacuum line tomorrow.

exactly what I was thinking.. and make sure your e-brake works! oh wait.. convert to a hand e-brake!

I was thinking this weekend.. what about an electric motor.. using a "dimmer" slide or something similar to move an electric push rod? I would have to see what kind of stuff there is out there.. might be even more difficult than what you are currently doing..

getting close though, keep it up! :bowdown:

If it were me, I would have looked into computer contolling the clutch. It would have been easier I think. Alot of the robots use computer controled ford window motor's.

i don't think the window motors would move quick enough. it would need to be something that would have an "instant" response to the movement of the clutch lever... and match it's movement over the range allowed, thus controlling the clutch...

that might get tricky.. it's possible.. but then you need to burn a board for control, or get a small computer to control it. once the hydrolics are up, they are more fail safe I think.
