nissin master cylinders

[fj11.5]

hi all, anybody else had this issue , , i had been using matching nissin 5/8 mastercylinders urine cup models from a yzf , th clutch one had a very light lever pull  even with a new fjr  clutch spring, and the brake one had a very solid lever pull using blue spot xjr brakes, , anyway my clutch master started weaping fluid from the piston area so i changed it over to the xjr master ive had all clean and ready to use if i had too, , as they looked odd i changed the brake master to the xjr one that came with the blue spots,, now the odd thing is the brake pull is  soft but extremly useable and works a lot better, thought they were great before, and the clutch pull is heavy,, anybody tried the same tyme of masters i would of thought being both nissin and from late model bikes they would of worked the same ,

Edited out everything I said, because I'm a dumbass who can't read properly.  Nor type, it seems.

Is one of them from a radial type?  Are you sure that they're all the same bore?  Are they all in comparable condition?

More likely they're using a different pivot angle/geometry stuff between the lever and the piston, that'd be my only other guess tbh.

the two i had on before the swap were both " urine cup models " guess that makes them radial type ?? the two im using now are from the same xjr, if its any help they all use my short adjustable levers  ( ebay specials  )
