Picked up another member's long term LS2 project in October and have been going through the car buttoning things up further, tuning and increasing drivability. It is running a hydroboost setup w/ ABS delete, Willwood BBK up front and a Tilton rear brake proportioning valve. The problem I'm having is crazy stiff brake pedal feel - with almost no give. Brakes are firm, stopping power is fantastic but with no travel and little pedal feel I can't heel/toe which makes driving the car a little awkward. Happy to provide pics and more details on the setup but can't for the life of me figure out how to adjust this. ANY info and help would be amazing.
Cheers

Pedal travel is proportional to master cyl displacement, no?

100% correct. Just wondering if there are ways to adjust travel/feel (without changing master cyl bore) - as I'd read about how great the potential feel of hydro boost setups can be.
Don't know how the displacement proportions between the master and calipers could be altered without changing components. Perhaps an opportunity for larger calipers.

I'm sure line pressure could be reduced (perhaps with a restriction?)but the physics don't change. He'll still have same pedal travel just requiring more effort. Maybe that's what he's after.
