Hi Hemi 426
The drumbrake master cilinder has a smal valve in the output line to keep a
little bit of presure
on the lines all the time for disk brakes there is no valve like this
I did the conversion on my 57 and pics will be afailable within a month or
two
I took a master cilinder from a dodge w200 the bore of the master cilinder
must be the same as the original one
for more details please mail private
