DOT 5 clutch fluid
Just had my clutch fluid flushed out and put in DOT 5. HOPEFULLY this will solve my damn clutch pedal problem.
Anyone else run this fluid? I know a lot of you run the Valvoline synthetic DOT 3 and 4 fluid, but I opted for this. We shall see when I hit the strip on Saturday.

Update
The fluid helped out a bit but the pedal is still losing grab and is somewhat sticking to the floor. It is a lot better than it was before though. And it seems to rebound faster than it did before too. I guess now its, "hello new master cylinder!"

I'm in the same boat as you. I flushed out my fluid and it does work better but yea, the problem is still there.

It has a higher boiling point because it's a synthetic fluid. You're not supposed to mix it with conventional fluid. I think you're going to be in for a rather large parts bill very soon?

DOT 5 is not endorsed by SAE, i dont know much about hydrolic fluids but if you want a better clutch, go with the drill mod, or a better clutch package. DOT 5 is too thick and refine, besides its silicone based. So mixing it, no matter how well you cleaned your old fluid will still cause your system to fail due to all the precipitation that will eventually corrode your lines just like a clogged artery . Hell using DOT 4 is taking a risk, but I use DOT 4 in my PTO and holds up well.

I just spoke with my transmission tech here, and he said there are no parts inside the clutch that can corrode due to the siliocone fluid. But alas, I will be changing back to the Valv synthetic and upgrading to an adjustable master cylinder to hopefully take care of this problem. And I dont think my slave is leaking, atleast it didnt seem that way when we flushed it.

DOT 4 Has a higher resistance value (temp and psi) than DOT 3. Say that by some reason Dot 4 fluid is aging well by the time DOT 4 would break down some clutch components would be long broken before the fluid. (i hope made sense lol) It would be easier to show than to explain.

I'm pretty shure there is braided metal inside the plastic/rubber.

it sounds like you need to flush out the slave. Air trap in the lines will not help you clutch pedal return.. If all that check out okay then I would take a look at the master.
