New idea for e-brake?, don't think I've heard this one Options

[Krieger]

Last night I woke up thinking of a second redundant hydyraulic system for the rear brakes only. Perhaps a T-1 master, or some small slave cylinder attatched to a handle that could apply force for braking....Then I says to myself "self you could plumb this into the existing line going to the rear of the car and put a one way valve in that line to keep it pumping the rears only" Also a one way valve would be need to protect the e-brake pump from the main master cylinder. I know a cable is the ultimate redundant system, but this could be a cool compromise keeping complexity/weight/junk off those rear wheels.

If you want a true E brake then the last thing you want to do is plumb it into the existing line. A ruptured line = no brakes. Mechanical is the only way to go if you want to stop in an emergency. I've had all kinds of failures from ruptured lines, failed master cylinders, leaking pistons and pads ripping out of the calipers. Without a mechanical back-up I wouldn't be here typing this.
