Bob, sorry missed the bloody obvious full stroke.I'm not nit picking here, I'm just making sure we have the hole picture.
If the master cylinder bore is to small, is it possible that it will work "fine" with both circuits operating as they should, but in a one circuit fail, the master cylinder can't displace enough fluid to operate the one circuit now doing all the work. Irrespective of the ability to full stroke?
I'm still uncomfortable with using a smaller bore master cylinder than the original one, all else being equal.
I get your compromise bit, and I spose it's what your used to. I only drive old stuff, and work on old stuff. I'm used to brakes that you have to stand on, and I'm comfortable with this. When I have the misfortune to drive something "new" (read built from 1980's on) I'm shocked at the brake sensitivity. Read kiss the windscreen.
So pedal pressure isn't really a "given" what's ideal to some is unacceptable to others.
What say you.
Thanks
Martin.
