Replace Hydrolic clutch unit. Fix anything?

[Awdboost]

I'm debating on replace my slave and master clutch cylinders. Because of a weird conditon I get when it get hot outside. What happen is when it cold outside my clutch is smooth and not very heavy. When It gets hot or when I use my car lots my clutch get heavy and not smooth at all. I have a ACT 2600 and RRE steel clutch line. Has anyone had weird problems with there clutch system and replaced it and it fix all? Let me know. Thanks guys.

Did that done that. I've tried it all. I've got RRE Brake fluid in there and have bleed it so many times. I might just replace them because it not that expensive. But in hopes of fixing my problem. I know I've got lots of meat on that clutch left and would like to go more then 1.5 years on that clutch.
