stainless sleeves in wheel cylinders

[alt63bird]

Must be remembered that the style of cylinder used in Early V-8 cars '39-'48 are a stepped cylinder, with one end a smaller bore than the other. Ergo, two sleeves in cylinder being fed from one port with an internal joint between the dissimilar-sized bores would allow for fluid to leak past and push out one or both of the liners. Later cars use a single-bore cylinder which should make this kind of issue non-existant.
