... hmmpf ...
I have no knowledge of pre-1955 cars so this is an awakening. So the OEM wheel cylinder had two bore sizes, I a$$-u-me for balanced braking. So when one is sleeved, instead of machining the replacement sleeve with the two original size bores (step boring), the re-builder uses two separately sized sleeves together pressed in from either end,
That explains it.
THANX! for the education ...
