jeez ogre, you didn't have to pull your cab off just to show your system.....lol.
nice explanation and pic showing your hydroboost set up.
it makes sense to check the master cylinder travel when setting up the pedal, a full pedal stroke should equal a full master cylinder stroke with just a little bit of pedal stroke left over for safety. then the pedal could be shortened if it needs to be, like ogre did, once you find the sweet spot where the brakes are full on and hard pedal. personally i wouldn't shorten the pedal unless you have legs 9 ft long so it is uncomfortable or it is just simply waaay to high off the floor to find it in a panic stop situation. possibly adjust some of the linkage to bring the pedal height down? make an adjustable pedal where it connects to the lever under the floor?
