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 guess the basic thing is that all 914 came with the dual circuit design, and have the proportioning valve in the rear. So really of interest to teeners is an adjustable proportioning valve (been around for decades) or deleting the valve.
