when i do this will i feel a difference in the clutch? i understand the fluids in both systems are connected, and right now the clutch seems to grab a bit sharply, i hope it is influenced by the old brake fluid, i will let you know, but first... a nice ride...

 

i didn t notice any change but i changed mine at about 9k miles and two years.. the fluid came out pretty clean looking.

 

I've never felt any change in the break pedal after a change. That said, I've never let it get too old or overused prior to a scheduled change.
