Hydraulic E-brake diagram?

you have to make it completely separate from the OE braking system, otherwise it will just push fluid up to the master cylinder i.e., separate e-brake calipers on their own dedicated hydraulic system. Check valves won't work because fluid would flow to the caliper and then not be able to relieve itself. You could possibly put Normally Open electric slave valves in the main rear brake lines that actuate closed when you pull the E-brake handle. It's a lot of work & expense for what purpose? Otherwise the only time you will have rear brakes is to pull the E-handle. This should be limited to a dedicated drift-only vehicle.
Maybe there is some scheme that somebody developed that isn't obvious to me. Not claiming to be an expert, just spending a minute or two thinking about it.

Do this mod at your own risk, I am not liable for anything that happens to your car. I did this back in school with some classmates. Our system is a diagonally split braking system meaning,example master cylinder line 1 uses FR and RL lines to brake evenly if one of the 2 master cylinder lines go out. We found that out the hard way tapping from the brake master cylinder.
So what we ended up doing was taping the rear lines after the ABS module. Tee the rear lines into one and feed it to the hydro, and out from the hydro back to the hard lines. effectively turning a 4 channel ABS to a 3 channel ABS. So far its been working great, had it for almost 2 years. Since the lines were extended, the brake pedal lost abit of feel, but it works great with heel toe. no issues with brake, hydro works like a champ, looks up with a 1-2inch yank.
heres my crappy drawing and some procedures.
