I have the ec brake setup and the mechanical bias controller. Although I set mine up a little differently, it is towards the front of my chassis, actually out in front of my brake pedal so it pushes on the master cylinders. Haven't quite gotten it perfected yet. Although I did learn its tought to figure out but I still have a large hiccup in the system, I don't think my dual outlet rear master with one outlet plugged is right. It feels like that master is rock solid pushed about half way down, the fronts can be pushed all the way in and the pedal is decently firm. So advice at this point, if your going to push on the masters and have a single inlet caliper, use a single outlet master!!! Lol
