I'm just totally confused by this...in one place you say....
larger cylinder = more fluid with less pressure,  and in the other place you
ay:
arger cylinder = less travel with more effort
You also state:
smaller cylinder = less fluid with more pressure, and in the other place you
ay:
maller cylinder = more travel with less effort
Please dumb this down even more for me so I can comprehend.
Thanks,
oward

ou have two things to consider with hydraulics:
. The volume of fluid that must be moved and
.  The pressure needed.
o...
arger cylinder means more fluid (per travel inch) but less pressure  (Your
ot pressure over larger surface area = less pressure)
maller cylinder means less fluid  but more pressure
he fluid moved needs to be the distance the clutch slave cylinder needs to
ve by it's bore.  This volume changes depending on which size cylinder you
ve.
o, in general, a smaller cylinder will give you more travel and require
ess
fort and a large cylinder will give you less travel and more effort.

. see, I gave you all sorts of info that wasn't helpful!  ;-)

 I can't get my Rivergate clutch slave set correctly. It really seems like

n't have enough throw. So my simple mind is asking - "Which master cylinder
ovides more throw? A 3/4" or a 7/8?" Did my '62 have a 3/4" of 7/8"? I
hink
now have a master out of a 65...
 Any guidance you can offer?
