There are plenty of accounts online of the repop metering valves leaking. My first one from Inline Tubes leaked so they sent me another one. The second leaked ever so slightly so I stuck with it. Now as I actually drive and brake, the thing leaks REAL bad under pressure from the pedal. I removed it and took it apart to find a very poorly made seal. From my readings online this seal cannot be bought separately.
Am I faced with continuing to get replacements until I receive one that doesn't leak? Has this bad part/leaking been resolved in the last couple of years and I missed it?
I understand that this valve delays the front discs for a split second when the pedal is applied. Can this thing be "gutted" and plugged, removing the "delay" and not adversely affect the braking?

I called Fine Lines. They had them in stock. They tell me that the internal parts are from china HOWEVER, most sellers have the units assembled in China. That's where the issues are. Fine Lines receives the parts and assembles the units themselves, weeding out bad seals and assuring that the valves are assembled correctly. I took his word for it and ordered one. I'll let you know.

I thought that I was the only one. My new valve leaks from the hex head plug at the end. I can't tighten it any tighter and I was going to pull it this week to see if I can add a seal. I don't recall which company supplied it though.

Yep, my re-pop leaked also. Sent it back. Received the second one. It leaked also. Tigtened the crap out of it & put teflon tape on the threads & has been trouble free for 3 years or so now.

If the valve is on the car, how much fluid will leak out when I remove the hex head plug (facing towards the ground on the car)? Will I need to re-bleed the brakes? I want to try the teflon tape idea. Thanks

Yes you will have to bleed the brakes... I have used teflon tape on them in the past and worked great for me

I pulled the valve block out of the car and that plug was very tight. So I pulled both the bottomplug and the top fitting and added teflon tape to both male fittings. I will have it back on and will be driving the car this weekend to test it again. Thanks

I have had at least 3 that have leaked so far. Everyone I have bought so far has been assembled and never tightened up.You would think they would be a little more critical with brake parts but what do they know about making brake parts where they are made. They ride bicycles.This has been a ongoing problem for at least 3 years. I would keep sending them back until you get one that does not leak. If they are going to sell you junk parts that they know have a problem. I would make there job difficult and make sure they loose there profit in shipping cost. They don't care about your labor.
