OT but hopefully interesting: single to dual brake line conversion Options

[Tdskip]

So I need to get this thing ready for a charity event and that includes new brake lines. I converted it to a two line, split front and rear, brake system for safety purposes but haven’t finish3s the hard lines yet.

I’m thinking having a proportioning valve in the system so I can adjust the front/rear bias would be a good idea but am not sure how to plumb that.

I have a conventional mid ‘90s Toyota dual M/C now.

Figured our racers here have dealt with that so thought I’d ask. For those that have done this where did you put the valve? I’ve seen two types - one where both lines from fhe MC go to a combination valve and splitter (pictured below, just an example I haven’t ordered this yet or decided to go this way) OR a set up where only the rear line goes through the valve.

Thanks in advance for any ideas and coaching.

I don’t get it either... you already have a redundant master cylinder that separates the front from the rear and an emergency brake. Why go further than that?
