V1 Brake Fluid Leak

[Adam in CLE]

take a picture of where your clutch line connects at the transmission and post it here.

I have the same connection as everyone. Hard to see it with the motor and fuse box in.

Any tips on getting the elbow off? Don't want to break anything while trying.

I believe it has two retention clips. One holds the clutch line in to the elbow and one holds the elbow on. Once you remove the clip holding the elbow on, it should come right off. Be prepared for brake fluid everywhere.

Thanks. For others, to get the elbow off, you need to pry it after the clips are removed. I removed some of the brake fluid so I wouldn't have a mess. Does anyone know if the washer that is in the elbow should be on the fitting? I have an o ring on the nipple that protrudes through the transmission housing and then a conical seal that is in the elbow itself. Should that come out and go on the nipple or stay put?

I think there should only be one seal, but it's hard to follow your question. Maybe a picture?

sorry, will post one in a bit.

I'm not super confident in my answer, nor am I super confident I understand the question, so anyone please feel free to correct me if need be-

there's an o-ring on the brazed end of the DF hard line that goes into the elbow from the front end of the car, and I'm pretty sure there's only one seal on the clutch pipe that goes into the elbow from the slave cylinder. Not the best picture (from ZZP's website) but I think the seal on the clutch pipe is this whole end cup sealy deal at the end of the clutch pipe nipple. I don't think there's supposed to be another o-ring in there, but it's been a while since I've been in F35 clutch hydraulics.

Pretty sure that shouldn't be there. And you have a seal on the male portion? If you look at the picture on ZZP Hydraulic Clutch Elbow – ZZPerformance you can see inside the elbow.

You didn't replace any of these parts?

 

[Adam in CLE]

Rauq and Gtstorey are correct. I had to blow up the picture. None of these parts were replaced or even taken apart until today. The gasket was in the elbow fitting. I wasn't sure about it and didn't want to take something out and risk ripping it. On the nipple, it looked like there was an o-ring but was a ledge for the gasket to fit on. I am good to go here. Going to put it all back together and fill with fluid. If it leaks, I will be taking the engine out of the frame. Thanks all!

 

[Gtstorey]

Take the seal out of the female part and install it on the male. It probably wont seat correctly to just stick the male portion in and clip it.

 

[Adam in CLE]

Thanks. Already have. I will try to fill the system tonight and test. Have a feeling I need pull the engine.

 

[Gtstorey]

Have you pressed on the clutch while watching the elbow for leaks? Not evidence of leak afterwards but leaking while under pressure.

Hi All! Brakes are done and working well. No need for a new master cylinder. However, I put new fluid in the system and it appears when I pump the the clutch, fluid leaks out the bottom of the engine where the engine and transmission bolt together. Nothing is leaking at the elbow the same as before. I would think the slave cylinder/throw out bearing would need to be replaced this I am going to have to pull the engine. Anyone have any thoughts before I do?

As a last ditch to stave off having to separate the drivetrain from the chassis, there's no chance you're looking at residual fluid from bleeding or anything like that, right? I've gotten halfway through bleeding before, only to realize my drain hose wasn't fully seated on the bleed screw.

Only other places it could leak are the threaded side of the clutch pipe or a leaky slave cylinder, and yes, you would have to pull the motor to do either.

Hi Rauq. No residual fluid or anything coming from the top. Was able to take a look inside and not seeing anything there. Thought it was brake fluid but could be oil from a bad main seal. Going to test a bit more and see if running the motor (has been sitting for about a year) could help seat anything and solve the issue.
