What Master Cylinder

Yes, I need to slow down and organize my thoughts when trying to get them in written form. I’m more of a verbal conversation kind of guy and I sometimes get frustrated by the amount of time required for written messages to go back and forth so I cram too much together. Although I have a lot of experience working on cars, and trucks, and Jeeps, I have not had a whole lot of experience on pre WW2 stuff. I am trying to get all this information down on paper so that I can build a notebook with it, I am old enough that my brain doesn’t seem to be able to keep quite so many balls in the air at the same time any more.

I think that when you corrected the typos on your drawing the drawing disappeared. It would be a big help if you would re-post that because I want to print it out. Thanks!
 
Good plan on putting it together in a notebook.

I see the drawing I posted fine. I'll send it to as a PM now.

Does Cardone possibly make a remote reservoir conversion kit for the 1923? I have such a set up (in this case Willwood) on my Willys and it works quite well.

Not that I know of. These stepped bore MCs weren't widely multiple application used.

You mentioned that you picked up a " ... including the Boling Brothers battery box master cylinder set up (which I will not be using)"; you may want to take a look at using it along with a Mico Dual-bore (stepped) master cylinder that I mentioned with link in post #8 above. They also have boosted designs and remote reservoirs. You may want to give them a call.

Attached is an old Street Rodder magazine article and a Mico catalog that I trimmed and highlighted a little.

I appreciate the information Glenn, I won’t be using the battery box because I have relocated the battery to the bed of the truck (in an old tool box)because I really disliked having it under the car. I can use the Cardone without a remote reservoir if necessary.
 
Read all the Mico stuff you sent, very informative! The Mico looks like a wonderful unit, my only concern being that it does not offer a split system to separate front and rear brakes.
 
I called MICO tech support, I was told that MICO makes nothing for an on highway application, turns out that article was written in 1974, neither of the 2 guys referenced in the article is still there, the part number in the article is obsolete. When I pushed the guy he was able to cross reference the old part number to a new one that has the same specs as the old one. He is sending me some drawings for me to look over.
 
Good on making the call. I attached their latest catalog above so the number should be listed there. Please post the drawings you get from them.

If anybody wants to pm me with their email address I will forward the information that I got from MICO and then you could post it. BTW Glenn I have a different part number that has specs the same as the unit in the article (03-020-411) and would be better suited for our application as it has a smaller N bore. Anyway, all that aside, I do not see any advantage to the MICO when compared to the step bore Cardone. I don’t see any mechanical advantage to the MICO vs the Cardone. When you consider that that article was written in 1974, long before the step bore Cardone came along. I believe that essentially the Cardone is using the same technology, possibly they cloned the MICO.
 
Glenn, I’m sorry but I have not been able to see that last edited drawing that you posted. I believe that you posted it on here but I couldn’t see it, and you said that you sent it to me in a pm and I still couldn’t see it. It’s very strange and I can’t explain it but I have had it happen before. I really would like to get it so that I could print it out and put it in my notebook. I have been told not to post my email address on here because undesirables can get it. I will send my email address to you in a pm and hopefully you will be able to email it to me. Glenn, Coopeman, and the rest of you, you have been such a tremendous help to me, I can’t begin to express my thanks and appreciation.
 
Thanks Don,

These are the drawings, instructions, etc., that Don got from Mico. They recommended a large bore (N-1) of 1.50" and a small bore (N) of 0.875. It may be possible to use a remote fill with this master cylinder.

- Small size
- Advantages of a stepped bore, i.e., large volume at low foot force.
- Reduced pedal travel
 
I guess I should have been more clear, I meant as compared to the Cardone which I believe offers 2 of those advantages.
 
Resurrecting a very interesting thread for a similar question .

I have a 1932 ford roadster I inherited from my grandpa. It has the 38ish juice brakes in the front with 1.25x1 bore. In the back I replaced the 38ish brakes with bendix style brakes that have 1 inch more.

My MC is bolted to k member under floor and I think my pedal ratio is 4:1. My grandpa originally had a 1965ish single reservoir 1 inch bore master cylinder but I like the ideal of dual master.

I saw the suggestion for the 60s amc master cylinder but also glenns 10-1905 dual bore seems like it would work better for me?

Any thoughts on what’s best with this setup?
