Possibly dirt in the master cylinder bleed hole not allowing fluid to return.
. . . How do I clean such a thing to see, or is there a simple/ cheat way of going about it heheTake a toothpick and push it through the two little holes in the bottom of the master cylinder.

Are they all sticking or is it just one piston? And what bike is this on, Steve?
hmmm wonder how how i tell one or all, pull the calipers off and see if one hesitates to go back in?
Never mind....ZX-9 eh? Yes, Connie has linked rubber brakes, 1st bike I ever owned I left the I left OEM lines and pads
Tell us about the ZX-9, Steve. We loves a good story, we does. Does it have two front calipers or just one? If two, are both seizing? If one, apply the brakes until it seizes and then open the affected caliper bleeder and if the fluid shoots out (put a rag over the bleeder just in case), then it's an issue with the line on back to the master. If not, it's caliper related. Of course it has two, its not a Hardly-Ableson. If I recall both calipers are hard to pull of after a very short ride, but i may need to confirm if one is really harder than the other..... good question for me
By the way, is that the only thing you did (replace lines and bleed) or did you muck about with the calipers and did you change the banjo washers? Changed lines, banjo bolts and crush washers (all Spiegler)
