so to the person that guessed no pedal left. you win.

I cracked open the bleeder screws and it still didn't go down any further than if they were closed.
I know the pedal and booster have more movement because I disconnected the master and I can put the pedal to the floor.

looking at the corvette booster and master combo, there is no way to make that work with this bracket setup. the rod on the back of the booster is too long. it would be engaging the booster when I bolted it up.

not sure if replace just the master is the answer. maybe as someone above said, internal bleed by so it isn't giving enough force, and that might solve it.

going to a smaller bore doesn't seem to be a good idea, if I am maxed out on distance already.

the volare one is too big in diameter.

I did find that the a body ones are 7 inch boosters and would bolt in, but not sure about braking force.
