this will only help to the guys who have twin leading shoes,
i never had a firm paddle with my mini, i was using a master pump with bore 0.625".
then i baught a pump with bore size of 0.75" .and i used a longer pushrod with it,
now i can stand my mini in front wheels with one paddle.
----theorytically this is what happend----
the distance travelled by the pushrod-L
i was pumping ∏*(0.625/2)*(0.625/2)*L cubic inches of oil before
now i pump ∏*(0.75/2)*(0.75/2)*L cubic inches of oil
do the math
its 44% increase of pumped oil!
people using the 0.7" bore pumps ,can gain 25% more brakes with a .75" bore pump
A low cost way to improve brakes!!

Using a longer pushrod doesn't mean the piston travels any further at all, the travel of the piston is limited by the internals of the M/C.
And the volume of fluid pumped doesn't really matter as the volume of fluid the S/C's can take is unchanged. What you are doing here is increasing the line pressure.

To some extent that's good news, but I think you had the wrong one to start with.. .7" master is fairly standard throughout the range ( what I mean is the bore is standarded, even if it's a single, split, or tandem system ) with only the single leading shoe'd minis using the .75" version.
It sounds like you had a Clutch Master as your Brake Master.

yeah i know,
.75 is from a single leading shoe mini.
my clutch has .7 " bore pump now
but any way now i feel totelly different about brakes

the problem is that you loose modulation surely
