so glenn does your brake pedal stroke feel normal, as the svc manual calls for a specific 44mm clevis pin measurement that appears to have a relationship to the piston stroke length and makes no mention whatsoever of using the clevis shaft to adjust pedal position. this along with your mention of having to rebend brakelight spring leads me to believe this is armchair engineering at it's worst. thx for your response but ima gonna try rebending the brake pedal arm about an inch lower first before i mess with re-engineering the master cylinder functionality.
STOP.... put the hammer down.... Nothing needs to be, or should be BENT....
everything we people here have said is correct,its all fully adjustable... you don't need to BEND anything... adjust the clevis, and also adjust the location of the brake switch... Unplug the switch first tho.... it has an adjusting nut to set it's location and height....nothing there needs to be BENT.
you aren't re engineering the stroke of the m/c piston, that piston tkaes so little movement to effectively actuate a properly bled rear single caliper, it is not a concern, consider the fact the front m/c can move fluid easily, in a minimal stroke, to effect 4 times more brake pistons...
you need to get down there and look,disassemble, and examine these parts, and listen to these folks before you break something.
