Corsa brake servo plumbing ? (In a hot rod)

[Jonny M]

Here's a weird one for you guys;

I'm building a hotrod, but needing to use a vertical drop Corsa B brake pedal

Question is, which brake pipe feeds the front and rear circuits?

I was guessing rear to apply first, so thought that'd be the bottom outlet, leaving top for front circuit?

Any help appreciated

Jon
