Default How long before you should change your clutch fluid?

Pedal has ben feeling mushy lately. Think I need to bleed it or just change the fluid and get a ss line?

You should do it when you do your brake fluid. You might as well flush it out and put new fluid in.

Since the clutch line isn't exposed to high temps like the brakes, there's not much point to running something other than DOT 3/4 in the clutch lines.

I am. I had some left over when I did my brakes. It helped the feel of the pedal and shifting became easier. I am still amazed at the things I had to do to a new car to get it up to snuff.

Brake fluid is hydroscopic, btw. High temps or no high temps - it will absorb water. You need to change it on a regular basis.

There's two problems with water being absorbed into the brake/clutch fluid. One is that it lowers the boiling point of the fluid - in the clutch system this is NOT relevant as it never has to deal with 300+ degree temperatures. But it also can cause corrosion, and you really don't want it to rust the bleeders and such in the system, so it's a cheap thrill to swap it out when you do the brake fluid - at least every other year.

Ah, yes. The leading cause of slave cylinder failure.

Hygroscopic, not hydroscopic.

From what I understand, DOT 3 is less hygroscopic than DOT 4...

For bang for the buck, the way to go is Valvoline Synpower Dot 3/4 fluid. It is much less hygroscopic than standard Dot 3 & 4 fluids, pretty cheap and easily available, and even when it has absorbed water, its boiling temp doesn't drop nearly as low as with standard fluids.

Teflon brake lines (which don't expand like rubber) with stainless steel sheathing over the outside to protect the teflon.

Same concept as Stainless steel brake lines.

Which you can use the same ones(well at least on WRX) and get 4 clutch lines instead of 1 for 100 bucks. Their just a bit longer.
