  Okay rub it in. Nice drive on a winding pennsy back road.  Good for you. 
   I hope those shocks work well, I didn't go for extreme just usable, after driving the thing I'll make adjustments.

I have that problem …. 

I bought a set several months ago.
Finding them is the problem, they are not where I was sure I had put them.
Life WILL be simpler when I have fewer projects. 

I'd like to know what you find out; I have a standard TC MC here, as well as an S2 (albeit rusty, but with the proper innards) that's been sitting for a while.  If they COULD sleeve down properly, use the TC as the base with the S2 innards...that would be the hot ticket, I think.

Going to have to make a decision soon; filled the reservoir a couple weeks ago, but when I checked last night, it was down again, above the 'MIN' line, but still down...

Bryan, would you be willing to lend me your S2 MC so I could do some reverse engineering on it? I have the TC MC drawn up in CAD and it would be great to do the same for the S2 MC to see if merging the two is feasible. I would gladly pay shipping both ways, obviously.

I have fitted a lot of master cylinders and worked on a lot of older cars.  Single circuit masters last much longer than duals and give far less grief.  Single circuits are also simple to install and bleed.  Fit a cap with a level sensor and you have all the warning you need if there is an issue.

I have seen both leak due to corrosion at the exposed end but only dual circuit masters have internal issues and bypass.  One famous example was when VW upgraded from single to dual.  Again no notable problems with the single but the dual was famous for going from good to ON-THE-FLOOR in an instant.  Yup, would bypass BOTH circuits!!  If you have a dual system, by all means keep it that way.  Just remember to change the master every 40K or so as preventative maintenance.  If you have a single circuit, just fit a sensor cap and thank your lucky stars.
