That's probably true, but maybe Bill's simplest fix would be to simply change the booster mounting angle and go to a higher pedal ratio. That's why I asked where it is now.
Yes it is quite a bit for one leg. But I think what Bill is trying to do is address those panic stops since he's trying to lock up the tires. At least that's what I understand. He said the MAXIMUM pressure he can get is 800 PSI. I'll bet he's applying a lot of force to the pedal to get that.100 pounds pedal force is a lot. I think this is panic stop territory, not normal driving territory.
