I am running a 5/8 nissin mc with a stock sporty single piston caliper on my current build, it hasnt seen pavement time but just pushing it around and testing it on the lift i can feather the brakes just fine. being that 5/8 and 9/16 are very close in size i dont think you will have an issue.
for other people wondering about sizing of mc and calipers and what will work together i think its safe to say that if you are close either way it will be ok. to aid in sizing issues here is a little inch to millimeter conversion chart to help out
1/2" = 12.7 mm
9/16" = 14.28mm
5/8" = 15.87mm
3/4" = 19mm
1'' = 25.4mm
if you have a size not listed and want to figure it out do this: lets pretend you have an 11/16 caliper and you want to know what that is in mm to match up an mc, if you divide 11 by 16 it will give you 11/16 in decimal form: .6875. now take your .6875 and multiply it by 25.4( the number of millimeters in one inch), and it will give you the mm equivalent of 11/16: .6875 X 25.4 = 17.46 11/16" = 17.46 mm
if you understand fractions and decimals then you just wasted your time reading this, but for anyone a little math challenged i hope this helps.
