CDV install bleed problem

[SpacE82]

I'm installing my CDV and a lot of fluid leaked out. We are trying to bleed it and no fluid is coming out. We've tried the clutch and we got a hand pump and still nothing. It seems like there is no fluid moving from the brake fluid resevoir. Whats going on?! Please help!

I may be wrong but there should be a separate reservoir for the clutch......I am not sure, but I know my subaru had 2 reservoirs, 1 for brakes and 1 for clutch

It is a shared resevoir. Both brakes and clutch use it.

The resivoir is divided by a partition internally, the small portion in the rear, drivers-side, top corner of the resevoir is for the clutch. The rest is for brakes. The car need to be jacked up evenly in front, not from the side (to push the fluid to the back/top and over the partition to get to the clutch portion) and kept completely full, otherwise you will drain it pretty quick during bleeding. Jack up the front, then keep toping it off as you bleed.

Took me 2 hours to figure this out when I did mine.

Interesting. I didn't realize that.

Yeah we figured it out...5 hours later lol. It is a shared reservoir, there is like a divider behind so when you look into the main reservoir it looks full, but the "clutch reservoir" may not be. We found another DIY and they talked about the two reservoirs. So we filled the second part and tried bleeding it again and it worked...pain in the ass and it took soooo long to figure it out.

The problem was that when we initially unhooked the stock clutch delay valve, the "clutch reservoir" probably got drained...but looking at it from under the hood, it looks full..

Everything is ok now, long day/night, but its all good, and it really does make a difference.

P.S. Thanks for the responses..I was freaking out, I actually called Roadside Assistance to see what the process was lol. I told them I dont need RA yet, but I might soon haha

I used a brake-line clamp on each side of the the CDV pipework and had no problems with the install - took 20 minutes and I didn't need to top up the reservoir.

Mad.

I wouldn't pinch the lines at all. It doesn't make me feel comfortable. Get some air in your line and bleed it. Safer.

[SpacE82]

Yeah, I think the best thing to do is once you unhook the stock CDV, just try to limit the amount of fluid that leaks out by pointing the end upwards. That way it will leak out less. Our problem was a lot of the fluid, well all of the fluid, came out as soon as we unhooked it.

was the breakfluid reservoir cap open ?

Holding the line up should not help at all. The reservoir is several feet above the hose.
Pinching the hose will keep "spillage" to the minimum.
The reservoir is tiny. Hard to keep it full without pinching the line.
I modified my stock CDV.(free mod)
The bleed screw at the clutch is the real bitch.

I'll second everything you just said and add. MOTUL pressure bleeder is the only way to go. max fluid under pressure and a one man operation with a lift. just pressurize lift then bleed till your hearts content.

[SpacE82]

Yeah we used a pressure bleeder too. It definitely helped out a lot.. But the biggest thing was to avoid spilling.. you could probably even just put your finger over the whole until you get the new CDV on and then hook it up quickly.

I guess we were able to stop the spillage by putting the line up because, well, the resovoir was empty

To help people in the future, keep in mind there is a little partition where the "clutch reservoir" is in the main reservoir. So if you do have trouble bleeding it, you wont have to spend 8 hours trying to figure out WTF is going on and why it wont bleed haha. So just fill the main reservoir so that it fills back there.

"you could probably even just put your finger over the whole until you get the new CDV on and then hook it up quickly"

That is exactly what we did. Spillage was almost Zero.

[mad chemist]

Don't agree with this at all.

These clamps are specifically designed for closing brake lines "without" damaging them. Spending a few extra dollars (£ in my) case, and saving 5 hours trying to bleed the system sounds like a no-brainer to me.

Mad.

[Evice]

bleeding is literally 45 seconds with bleed kit, manually 20 minutes..

[SpacE82]

Yeah, the kit was definitely worth it. Much easier than tightening and loosening the bleeder screw cuz its such a bitch to get to.

I don't know about 135s. But my bleeder valve was right in your face. May 2009 production my car is.
