Replaced my CDV tonight with one from Riss. Changing the valve is easy, but after 2 hours of trying to bleed the clutch, I've still only got about half a pedal. Topped off the master cylinder a couple of times and get good fluid low out of the bleeder valve when I depress the clutch. But after tightening everything back up, clutch only comes about half-way off the floor and definitely is not functioning properly.

Any tricks to bleeding the clutch lines out there?

Appreciate any advice.

ps. already did a search but all I found was a lot of "pump the clutch pedal" advice...already tried that.

Thanks

You need to re-fill the fluid into the system after the installation of CDV. you should press the pedal numerous times in order to make sure that everything is right.

You are most likely getting air in there. The area in the master cylinder reservoir is very small and can deplete quickly. I used a power bleeder but you might be ab le to get it with someone working the clutch and someone working the bleeder and another filling the reservior. But if you are solo, try this:

Just give the clutch a good pull. It'll come up. It happened to me more than once while bleeding.

I think once you bleed out all of the fluid and the clutch pressure plate isn't under pressure but the clutch pedal is still on the floor, there's simply nothing to push the pedal back up. Thus a good arm pull does the trick.

After bleeding as best I could with a vacuum bleeder and my wife pressing the clutch, mine turned out just fine.

I agree.
The same thing happened with mine.

Thanks for the replies. Finally solved the problem as follows:
-fill the master cylinder as full as possible
-leave the cap off or loose
-let the car sit overnight
-the air will work itself out of the system

Seal everything up in the morning and you should be good to go.

Hope nobody else has as much trouble as I did, but if you do, try leaving system open overnight.

I'm not an expert on brake fluid, but I do believe when it is exposed to air it absorbs water. If you left your cap off overnight you may want to flush the system with fresh fluid.

This is a good product also for one man bleed:

Or you can make one like I did for $25.

seriously? I'd love to do the CDV delete if this is a good option. The only problem is this is my only vehicle so if there's a problem i'd be f*ked!

Can you use power bleeders by yourself?

That's the point of them.

The same shit happen to me 6 months ago. I bleeded topped it off with fluid the clutch had no back pressure I was pissed!! I had to take it to the dealer and they had to give me a brand new clutch which I was happy with I'm never doing that mod again fucken a big headache for something little.

Do this.

1. Top off the fluid, you can leave the cap off.

2. Open the bleeder valve and press the pedal all the way down

3. Close the valve and PULL it back all the way up with your hands.

4. Repeat until it comes back up.

Wow, what are you guys doing? Not clamping the line when you unhook it or something? You should lose very little fluid in this process. All you have to do is clamp the line, pull the CDV out, pop the restrictor out, plug it back in, open the bleeder, pump it about 2-3 times, then close the bleeder valve and you're done.

It really shouldn't be this hard. You could top off the fluid when you're done, but you shouldn't even lose enough to need to.

That's what I did. Used a vise grip to clamp down the hose and took off the CDV completely. You don't really need a delete for it. Saved me 25 bucks.

I know it shouldn't be that hard, but I followed the same instructions as everyone else. Valve itself is cake and lost very little fluid. Still, when trying to bleed the clutch, it just didn't go smoothly.

All's well that ends well.
