this may not be a problem but it bothers me a little bit. ive replaced my clutch master cylinder a couple times now due to the inner seals leaking, and ive noticed lately that my clutch pedal has some freeplay in it. and when i drive on the interstate for a longer period of time without using the clutch it feels really soft when i do use it. and it seems like the engaging point of it changes too. any ideas on what it is? or if its a problem?
