You'd need two, and they'd go in the lines leading to the rear brakes anywher i think would be ok

If your going to the trouble of this, then I suggest you run a single brake line to the back and T it off on the beam, then you need one adjuster, you save weight and get to mount the brainded line through the car full on race/track car stlyee.

I assume you've adjusted the valve you currently have on the rear beam?

nope you don't long as they work one if fine, it's also a good weight saving over two of everything, and becuae the rear do so much breaking and when is the cylinders are so small next to a V6 or 4 pot caliper it's fluid requirements are much less hence not needing two line and one is fine.

You basically need to re-do the brake lines going to the back of the vehicle. You will see on the Tweeks website that they sell all the bits to do it - you only want one line going from the master cylender to the rear beam. On that line you put the bias valve, then when you get to the rear beam you slip in a T piece and route some hose to the calipers....
