This is kind of an odd question, but is the stroke required for a single as compared to a dual reservoir master cylinder the same? I recently converted my original power brake 1964 Polara to front disc brakes and in the process added the disc/drum dual reservoir master cylinder. I was wondering if the original power brake booster would have a long enough stroke for the new master cylinder.
 
I would think so.When I left the single for a dual there were no issues with the manual set up.I later installed front disc and have no problem stopping from 147 MPH at the track.

Actually, the stroke for a single is a bit longer than a dual because the MC piston has to displace enough fluid for all four corners. With a dual, it is like having two pistons inside the MC dedicated to each circuit. That's why the pedal sits slightly higher off the floor with a single. The difference is just slight.
 
Lose a wheel-cylinder or brake-line at speed, with a single. Happened to me.....ONCE.
 
Yes no fun when pressing the pedal to find nothing. Have had it happen a few times.
 
Put a dual master on my 66 Satellite ,drums no problem. Just bought a 67 drum master and put it on.
