usually its 1" down on quite a few vehicals we have a chart that I can't find right now. We are MPbrake dealers and they say 2.1/2" You may want to check the booster pin length to make sure its in contact correct. You should have a firm pedal with the brake kits.
Your mc should be fine if its off but that can be checked as well.
these components no matter the mfg all work the same. if its correct
