ok my clutch pressure flucuates. what i mean by that is when the car is started up, the pedel pressure is soft with a little bit of play. but after about 20minutes of driving the pedel gets stiffer and "longer". its tough to explain, basically it gets longer so that i have to lift up my leg higher to get my foot on top of it. i dont know if that makes sense or not but. usually theres a little bit of play in it, but after driving for a bit it seems like it builds up more pressure and makes the pedel pressure longer.

anyway theres fluid, its bled properly, and it has a new master cylinder. any ideas or suggestions would be great. thanks

sounds like there is eithre air in the lines or the brake fluid has absorbed water. id flush and rebleed again.

I concur, you either have air in there, or wator(vapor) either of those 2 elements will expand when temps get higher. Thus meaning that the will cause more pressure in your line. How is it that you are bleeding the clutch pedal?

what year is your car? what engine tranny combo are you running? and how old is the clutch in there? Did the problems start after you did some work or no? more info please.

engine and tranny= h22 , clutch is a new cm stg3 car is a 97 civic coupe.

i bleed it the only way you can by yourself that i know of. basically i just take the clutch line off the slave and pump the clutch until fluid comes out then reattach the line. worked millions of other times for me so.. but i will re bleed it and see what happens. there could be some vapor in there.

well when you let up on your pedal air is sucked back in the line, unless you submerge the line in brake fluid to prevent air coming back up the line

easiest way to bleed it yourself is gravity bleed, just open the bleeder valve, take the cap off the clutch master and watch the fluid drain..slowly.

then you need to close the bleeder, move the pedal up, then repeat.
