Leaky hold-off valve

[peterro]

Why is this leaking from the rubber seal on the bottom of the hold-off valve? It's a new part. Is it something I need to do or simply call back Inline Tube to have them replace it?

Are the lines tight , using a flare nut wrench ? Often new lines need to be tight to seal .
 Cakk inline & see what they will do

 I just installed a Inline distribution valve & hold off valve just like yours, my distribution valve is leaking at the
copper gasket at the adapter for the front brake line from the master cylinder, it's a nightmare trying to keep the brake fluid off the paint. No amount of tightening will stop the leak, I will just clean up my original one & reinstall it ,at least it don' t leak, I will contact Inline.

Yeah, I've been using a line wrench for tightening. The leak isn't coming from the line connections, it's coming out of the rubber seal.

I installed stainless lines and I am having some issues with getting them tight/dry. What seems to work is to tighten them down, loosen, tighten, loosen, tighten 3-4 times to really get a good seat. The final tighten seems to be dry after that.

Since it was an all new system, I went with dot5 fluid to help with the paint issue.

And the answer is......

Call Inline Tube and they're shipping another one.

The one I got from them (Inline Tube) and it was faulty.  They sent a second one and it leaked from the copper washer no matter how tight it was.  I got to say I'm not pleased.

It looks like a simple enough piece to make , you would think the quality would be better !

Same problem here!! very small leak but it did not stay off the paint I have some touch up to do!! if it is leaking no matter how tiny the leak it is sucking air into the system. I will be doing some touch up's GRRRR!!

The question is, who makes the part. Would it be the same part from all the vendors? My one saving grace about the fluid getting all over is that everything is new and I used DOT 5. But it's still a mess.

[peterro]

Just talked with Inline again. Another hold-off valve is supposed to be on its way today. The 3 lines are dry but the replacement was also leaking out of the rubber boot.

I guess I wait on engine install again....

I've also had issues with the copper washer leaking on the distribution block. I think I've gotten it sealed now though. Aside from replacement, what has everyone done for their solutions? Did you go to a different vendor? Are these all made by the same manufacturer? Can they be purchased somewhere more common like NAPA or

Do yourself a favor and have your original one rebuilt!!!!!  In Line Tube distribution block and hold off valves are NOT to be trusted.  I had one crap out on me the way to a show and cause the back brakes to burn up.  The second one I got from them also acted like a one way valve and would not let fluid back up to the master cylinder.  Their stuff including their lines are total junk and I will never buy from them again!

You also need to use some pipe thread sealant on the threads of the stainless lines.  If you notice, stainless lines are either tight...or they are loose.  There is no in between like the standard steel lines.  Make sure you really tighten them down and use sealant on the threads as well as between the flare and the fitting.  When I did mine this way, the only leak I had was at the caliper bleeders.  I had to take those off and put some sealer on them.  I don't know if Inline Tube recommends the pipe sealant but Fine Lines does. 

[peterro]

Excellent. That doesn't hold my hopes high.  I can't have the original rebuilt because I converted from 4 wheel drum to disk/drum and didn't have the part before. I'll give it one last shot.

As far as my lines, I believe they're all dry now. What I did was tighten/loosen/tighten/loosen about 3-4 times to really get a good seat and then the final tighten seems to be dry. The only other issue I had was the copper washer on the top of the dist block. I think I have it dry now though. We were doing our final test last night (prior to engine install) and the hold-off started leaking again. GRRR.

 resq302 were you able to determine whether it was the distribution block or hold off valve that caused your rear brakes to burn up? got me concerned now.

Don,

The part that was giving me the problems was the t shaped thingy (some people call it a hold off valve, while others call it a proportioning valve).  Somewhere internally it was acting like a one way valve and not allowing the fluid from the rear wheels back up to the master cylinder.
